• Water treatment technology and systems

The odor problem in the foundry was immediately resolved with the deodorizer. The image of the tank shows the condition of the waste collection area about three days after starting operation, and customers who saw this were amazed, saying, "Can this much be captured?!"

• Drainage and ventilation equipment
• Gas equipment

There was a request to efficiently deodorize the dust and odors that scatter during the nanofiber manufacturing process, leading to the introduction of the dust collection and exhaust gas deodorization device, Deolizer. With the treatment from the Deolizer, the dust collection efficiency was enhanced and the exhaust gas absorption efficiency was also improved.

• Drainage and ventilation equipment
• Gas equipment

The dust, resin, and tar generated during the process of crushing and burning the mycelium substrate were causing complaints from nearby farmers, but by efficiently capturing them, there have been no complaints from the farmers.

• Drainage and ventilation equipment
• Gas equipment

There was a challenge in the manufacturing process regarding the deodorization of MEK (methyl ethyl ketone), rubber odors, and organic solvent odors (such as toluene and xylene). In some cases, there were concerns that secondary treatment might be necessary, but the primary treatment alone was sufficient to resolve the complaints from the neighbors.

• Drainage and ventilation equipment
• Gas equipment

Phenol and resin tar are reliably captured by deodorizers, allowing only substances that are insoluble in water, such as styrene, to be processed in the combustion system, thereby solving odor issues.

• Drainage and ventilation equipment
• Gas equipment

The exhaust gases emitted from the painting drying furnace are being initially treated through combustion methods, but they were not being fully processed, leading to complaints from nearby residents. Additionally, gases leaking from the drying furnace were lingering in the facility, worsening the working environment. However, the complaints from the neighbors have ceased, and it has become possible to treat the leaking gases that were accumulating above the factory, resolving the issue.

• Drainage and ventilation equipment
• Gas equipment

It became almost odorless immediately after installation, and not only did complaints from neighbors disappear, but the working environment also improved. The low running costs and minimal maintenance were appreciated.

• Drainage and ventilation equipment
• Gas equipment

In consideration of improving dust collection efficiency and reducing cleaning efforts, there was a challenge regarding how much dust could be collected and how much foundry odor could be reduced. However, with the processing of Dust Fall + Deodorizer, we enhanced dust collection efficiency and also improved exhaust gas absorption efficiency.

• Drainage and ventilation equipment
• Gas equipment

There was a challenge to reliably capture odor substances such as ammonia containing resin, aiming to improve the working environment and prevent pollution. After the installation of the scrubber deodorizer, the working environment was significantly improved, and the diffusion of odors to neighboring areas was sufficiently suppressed, leading to additional orders for scrubber deodorizers even in the existing casting line. Customers have commented that the removal is "almost too much," but since it mostly consists of inorganic soot, it is undeniable that there will be work involved in removing it. We have established a maintenance system in Thailand to address this.

• Drainage and ventilation equipment
• Gas equipment

Since it is emitted along with dangerous exhaust gases such as carbon disulfide and hydrogen sulfide, which do not dissolve in water, caution is required due to the risk of corrosion and explosion. As a result of the installation of the deodorizer, it was possible to reduce formaldehyde from several tens of ppm to a single digit.

• Drainage and ventilation equipment
• Gas equipment

Initially, activated carbon and other methods were planned for secondary treatment, but water-soluble organic solvents like PGMEA are captured at around 80% efficiency with just the scrubber deodorizer, and it is still operating while maintaining that performance.

• Drainage and ventilation equipment
• Gas equipment

It has been confirmed that water-soluble organic solvents such as PGMEA and acetone can be captured without any issues, and it has been found that a single layer of water film is sufficient for treatment, rather than requiring two layers.

In establishing the new factory, we were considering the introduction of deodorizing machines, but since the highly effective combustion-type deodorization is also very costly, we were exploring alternatives to combustion methods. At that time, we learned that Company T in Hiroshima Prefecture had successfully treated exhaust gases from their painting drying furnace, and they introduced us to our company. Because of the high trustworthiness from word-of-mouth recommendations from established customers, we proceeded with the delivery of the water film scrubber (exhaust gas treatment device) "Deo-Riser" without a demonstration experiment. Since the delivery was aligned with the new construction project, we were able to efficiently design the installation locations for the shower booths and circulating water treatment tanks, as well as the ducts and piping connecting each, while also significantly reducing the installation construction costs.

• Drainage and ventilation equipment
• Gas equipment

During the cleaning of manufactured products with organic solvents, solvent odors were being emitted and flowing into the offices in a separate building. It was necessary to effectively capture water-soluble organic solvents. By using one unit of the deodorizer DR-30W to perform water film cleaning with an airflow of up to 450 m³/min, we successfully kept the odor concentration below 400, even though it exceeded 1000 at times. The effectiveness of the delivered dust collection and exhaust gas deodorization system, the deodorizer, was recognized despite the difficulty in capturing VOC gases, leading to a repeat order. The previous issue involved a large outbreak of specific microorganisms in the groundwater that clogged the screen, but this phenomenon was resolved by administering chlorine and managing it at low concentrations.

• Drainage and ventilation equipment
• Gas equipment

The exhaust gases from the painting drying oven contain substances such as formaldehyde, resin, and tar, leading to persistent complaints from neighbors due to the irritating odors. Additionally, it was thought that installing a deodorizing machine would be difficult due to the limited space within the factory. However, the scrubber deodorizer was adopted because of its compact design, which allows installation in small spaces. Regarding the circulating water in the deodorizer, three months before the COD and BOD values reverse is considered the appropriate time for replacement. After primary treatment in the deodorizer, the concentration was reduced to 2 ppm, improving to a level that allows exhaust without the need for a secondary treatment device, completely eliminating complaints from neighbors. Furthermore, the water that captures odor components in the shower becomes formalin, but aeration by the Aqua Blaster promotes aerobic decomposition, making it reusable as circulating water. Additionally, since resin and tar substances are also decomposed, there is no adhesion to the pit walls, which helps keep running costs down and has been very well received.

There was a challenge in reliably capturing rubber debris and finely shredded wire. The rubber debris and wire were successfully captured, and there have been no occurrences of duct fires in the subsequent stages. Compared to the previously used wet-type dust collection and exhaust gas treatment system, (1) the capture efficiency has significantly improved. (2) There is no longer any concern about duct fires in the subsequent stages. (3) The screens have become less prone to clogging. Based on this evaluation, we have decided to deliver a total of five units.

There was concern that the exhaust odor from the painting drying furnace at the newly established factory might negatively affect the neighboring area. The exhaust was cleaned using one Deodorizer DR-4W with a water film. Since the startup until now, there have been no issues with odor at all.

• Drainage and ventilation equipment
• Gas equipment

At the charcoal-grilled chicken factory, the exhaust gases during production were causing local pollution, and there were no effective measures for deodorization. One unit of the deodorizer DR-30W (FRP specification) was used along with a deodorant spray chamber for cleaning. Although the odor was considerable, it was possible to eliminate all complaints from the neighbors.

• Drainage and ventilation equipment
• Gas equipment

When drying sludge generated from community wastewater treatment facilities in a drum to produce compost pellets, mainly ammonia-based exhaust gases are generated. It is cleaned using one unit of Deolizer DR-2W (made of PVC) and a dilute sulfuric acid drip system. While maintaining a pH close to neutral, it maintains performance with ammonia gas concentration reduced from 100 ppm to below 1 ppm.

• Drainage and ventilation equipment
• Gas equipment

Due to the request to prevent the strong odor containing chemical smells generated by the newly established casting line, we implemented a water film cleaning system with a gas flow velocity of 0.73 m/sec using one unit of the deodorizer DR-16W. The working environment has significantly improved, and the diffusion of odors to neighboring areas has been sufficiently suppressed.

• Drainage and ventilation equipment
• Gas equipment

During the vulcanization process in rubber product manufacturing, exhaust gas containing dust and organic solvents was generated, leading to complaints from nearby residents. There were concerns that secondary treatment might be necessary, but the complaints from the neighbors were resolved with just primary treatment.

• Drainage and ventilation equipment
• Gas equipment

During the manufacturing of rubber products, exhaust gases containing siloxanes and silicones are generated. There is a desire to capture these gases inexpensively and to deodorize them, leading to the introduction of a deodorizer. Approximately 80% of the siloxanes could be captured, but as expected, hydrophobic silicone gases escape, so there are plans to install a chamber that combines various filters for secondary treatment.

To establish a new recycling plant for leftover food, there was a desire to prevent odor issues, so a deodorizer was introduced. As a result, the goal of deodorizing to a level that does not disturb the neighboring factory was achieved, and the smell of leftover food is effectively captured, allowing the plant to operate without any problems.

In 2008, a wastewater treatment system was delivered to a bus depot (commonly known as a maintenance and washing facility). Before the delivery, a large amount of oil sludge was generated, but by installing aeration pipes, Aqua Blaster, in the existing water tank and performing aeration, we successfully reduced the generation to one-sixth. Since the oil sludge was being treated as industrial waste through incineration, this indirectly cut CO2 emissions by one-sixth as well. Although electricity consumption and maintenance costs for the aeration pipes, Aqua Blaster, increased, the costs for sludge recovery (cleaning costs) were significantly reduced, resulting in an annual cost reduction of 2.2 million yen.

Since it is not a designated facility, we had not installed wastewater treatment equipment until now. However, we received complaints from nearby residents about the foul odor from the wastewater, so we were consulted about implementing measures as cost-effectively as possible. Traditionally, we would have installed a buried type of blaster tank underground, but instead, we set it up above ground to reduce the initial costs of the wastewater treatment system. As a result, the foul odor completely disappeared, and the complaints from the neighbors subsided, leading to expressions of satisfaction from the factory manager in charge.

In 2001, we conducted treatment of a mixture of mineral oil degreasing cleaning water from mechanical parts and kitchen wastewater using a unit tank equipped with an aeration pipe Aqua Blaster. Although the inflow volume is small, the wastewater has a high concentration of mineral-based normal hexane extractables, which initially raised concerns. However, since the installation, we have operated without exceeding the treatment standards even once. As a result of successfully treating the wastewater at the facility, we received a repeat order for the wastewater treatment from the headquarters employee cafeteria.

In February 2008, we delivered a wastewater treatment system with a capacity of 30m³ per day to a bread-making factory. With the aeration from the aerator Aqua Blaster, we were able to maintain a dissolved oxygen concentration of over 5.0 mg/L even in the summer, and through collaboration with decomposing microorganisms, we successfully reduced high concentrations of oil and fat, which were at 500 mg/L, to a single digit within 40 hours of retention. Raw wheat flour, also known as β-starch, also flowed in large quantities, but until now, the treated water has never exceeded the contracted values.

In 2001, we supplied an aeration pipe Aqua Blaster wastewater treatment system to a school lunch factory that produces 12,000 meals daily and discharges 220 to 250 m³ of wastewater per day. Initially, there were issues such as foaming, but even after nearly 10 years, it continues to operate without any problems.

The 400t water tank was reduced to 200t, and despite the transition from river discharge to wastewater discharge, we successfully achieved an annual cost reduction of 15 million yen. Additionally, while 2.5 workers were previously required, after installation, only the removal of screened sludge was necessary. Furthermore, since the BOD and SS regulatory values in this area were below 600 mg/L, there were times when treatment was excessive, allowing us to stop the nighttime blower. As a result, we received the evaluation that it was "a dream-like wastewater treatment system," and the wastewater treatment equipment for the new factory was awarded a special order for the "Iens Innovative System."

Since it was a parallel two-system processing, to confirm the performance of the Aqua Blaster, all biological carriers from one of the towers were removed, and the Aqua Blaster was installed with the same air flow. Upon checking the processing efficiency, the load reduction rate for the conventional carrier processing was 24.2%, while the tank with the Aqua Blaster achieved a reduction rate of 39.1%. As a total load, it changed from 2,960 mg/L to 2,380 mg/L, resulting in a "1.24 times capacity difference." Even without the supported carriers, the performance was demonstrated, and it was naturally installed in the remaining tower, leading to the decision to remove carriers in other factories as well and implement the Aqua Blaster.

High concentrations of hydrogen sulfide were generated from the wastewater treatment facility of a renowned hotel, established by a major general contractor, exceeding the discharge standards. However, by installing a prototype of the Aqua Blaster, the hydrogen sulfide levels were reduced to 0.0 ppm, successfully clearing the discharge standards without using a pressurized flotation device. This led to a ripple effect in other top-tier hotels, and with funding from Hyogo Prefecture, it became the foundation of the current technology of Iens, as a "wastewater treatment facility without sludge treatment" (treating SS to below discharge standards).

Before the installation of the Aqua Blaster, a large amount of grease scum accumulated in just one day, leading to the formation of oil balls. Hydrogen sulfide was generated to the extent that it corroded surrounding equipment. The oil balls on the water surface and those that sank to the bottom were regularly manually retrieved and disposed of as industrial waste. As a result of installing the Aqua Blaster, the removal rate of BOD improved significantly to 80%, and the removal rate of normal hexane extractable substances improved to 82%. Even after more than eight and a half years, there has been no need for removal or dredging work, and a no-maintenance state has continued. The dramatic improvement in water quality has led to waterfowl visiting the sedimentation tank every year without fail. Below are the results from the installation in 2012 until 2020, covering eight years: - With a six-hour retention time in the adjustment tank, BOD and n-hex were cut by over 80%. - The floating grease and settled sludge that had accumulated in the adjustment tank have not been removed even once in eight years. - Hydrogen sulfide levels, which were at 100 ppm, have been reduced to 0 ppm. - The outlet of Aeration Tank 1 meets Setouchi regulations. - The sludge conversion rate for BOD has been reduced from 35% to 25%. - The sedimentation tank has remained stable, attracting ducks. - Excess sludge has drastically decreased, and the odor from its steam drying is no longer a concern.

At this factory, aeration was performed using a stirrer, but due to a lack of dissolved oxygen (DO), aeration was also conducted simultaneously with a disc-type diffuser. However, due to poor treatment performance, the existing blower was utilized, and the aeration device was changed to the Aqua Blaster AL-750, which allowed for proper treatment, leading to the complete shutdown of the 55W stirrer. Subsequently, the amount of sludge generated per unit of production was reduced, resulting in repeat orders for other wastewater series tanks. ★ Sludge reduction rate per unit of production → 18.8% reduction ★ Conventional stirring device 55Kw → Completely stopped

To prevent foul odors and enhance processing capacity in the adjustment tank, the existing aeration device was replaced with an Aqua Blaster, resulting in a reduction of BOD by over 30% based on the weighted average. Additionally, previously, chemical dosing was performed due to poor sedimentation in the final settling tank, but since the sedimentation issues have been resolved, stable discharge can now be achieved without chemical dosing. As a notable point, customers are very satisfied that even in cases of increased production or sudden inflows of high-concentration wastewater, the system can handle it without any issues. This has led to the special adoption of this system for pretreatment in related factories.

To address neighborhood concerns, 63 units of the Aqua Blaster AS-250 were installed to eliminate the foul odors, such as hydrogen sulfide, generated from the adjustment tank. After installation, when sludge was returned from the settling tank to the adjustment tank, surplus sludge (approximately 5.1 tons/month) ceased to occur, and electricity costs were reduced by about 10%. The person in charge mentioned, "The fact that we no longer need to manage the dewatering machine has greatly helped us, as the measurement work now only takes about 2 hours a day, reducing the work time to one-sixth." The BOD cut rate in the adjustment tank is 38.9% on average during high-load wastewater inflow and 61.4% during normal conditions, which has reduced the load on the subsequent aeration tank.

As shown in the table above, the pH automatically rises without the use of neutralizing agents, and the adjustment tank alone has cut the load by over 70%. Of course, it has also eliminated any foul odors. Later, a load more than three times higher flowed in, yet the adjustment tank alone managed to cut BOD by 50% and normal hexane extractable substances by 60%. The person in charge later emailed me saying, "The concentration of raw water flowing in is much higher than the figures we had heard, and it is remarkable that we are able to handle this load."

Due to the occurrence of processing issues, we decided to abandon the existing sprinkler bed and removed it, installing the Aqua Blaster AL-750 in the aeration tank. Until now, we had no choice but to use coagulants after passing through the sprinkler bed, but after the installation of the Aqua Blaster, we no longer needed coagulants even after removing the sprinkler bed. Additionally, since the treatment became very stable, we successfully included the high-concentration yogurt wastewater, which had previously been disposed of, in the drainage treatment, leading to a reduction in industrial waste costs. The recent analysis of the discharged water showed BOD at 9.4 mg/L, n-Hex was not detected, and other parameters also met the river discharge standards without any issues.

To enhance the processing capacity of the oil and fat components, the existing aeration device in the adjustment tank was replaced with an Aqua Blaster, resulting in an increase in processing capacity. As a result, the amount of normal hexane extractable substances was reduced by over 50% after passing through the adjustment tank, and other parameters similarly decreased, halving the sludge generated by pressurized flotation. Previously, the pH on the inflow side tended to be acidic, requiring chemical neutralization; however, now, due to the effect of the Aqua Blaster, it has automatically become neutral, eliminating the need for neutralizing agents. Additionally, the dissolved oxygen (DO) levels at the outlet of the adjustment tank have been maintained at 2.0 mg/L or higher, resolving issues with sedimentation in the final settling tank, and the odor of dewatered sludge has changed from anaerobic to aerobic.

Due to the increase in wastewater volume associated with the factory expansion, the aeration device of the existing treatment tank was changed to an Aqua Blaster to enhance processing capacity. By installing Aqua Blasters in the adjustment tank and aeration tank, we successfully accepted a load increase of 10-20% without increasing the tank size. Furthermore, it has become possible to carry out treatment without using a pressurized flotation device.

The work to eliminate the foul odor from the adjustment tank and the recovery of floating oils has been completed, and the Aqua Blaster AS-250 has been installed to improve processing capacity. As a result, although hydrogen sulfide had been accumulating and causing processing issues, the foul odor has disappeared, and the wastewater is no longer acidic, leading to a significant reduction in the amount of chemicals used. Furthermore, the manual collection of floating oils, which had been done three times a week, has been eliminated, along with the generation of 36 tons of floating sludge. Additionally, the final sludge from the subsequent activated sludge treatment has been reduced from 200 tons to 170 tons, representing a 15% reduction in volume.

A new Aiense Innovative System (AIS) has been established at a cut vegetable factory with a daily drainage capacity of 300m³. The processing flow is as follows: adjustment tank ⇒ 7 AIS tanks ⇒ sedimentation tank ⇒ river discharge. By returning the sludge from the sedimentation tank to the adjustment tank, the amount of sludge generated is minimized. The water quality analysis results show that, despite inflows exceeding the design load, all parameters meet the standard values. In another factory, issues related to odors have arisen, and the introduction of AIS is also being considered there. This is the first case that has proven the ability to discharge into rivers without using activated sludge.

At a tofu and soy milk factory in Shizuoka Prefecture, simply changing the aeration device in the first aeration tank from a membrane type to an Aqua Blaster resulted in a 39% reduction in sludge, leading to the shutdown of one blower. As a result, at this factory in Tokushima, all aeration devices in the tanks from the adjustment tank to the aeration tanks were changed to Aqua Blasters. The project was completed at the end of July, and despite several days exceeding 35°C, the system remained stable, maintaining the sedimentation tank in the condition shown in the photo. At this site, they also succeeded in reducing the inverter frequency of the auxiliary blower to 25Hz. It is planned that this blower will eventually be shut down as well.
