Until now, there have been very few methods to separate water from high-concentration bentonite wastewater using coagulants. With the combination of Ultra Separate BC and diluted hydrochloric acid, high-concentration bentonite wastewater can be easily treated. For dewatering, a cloth filter type simple dewatering machine is optimal. When treating bentonite wastewater with coagulation, it expands and contracts, resulting in strong additional resistance, making it impossible to process with standard coagulation sedimentation equipment. Our company has developed a coagulation sedimentation device specifically for treating bentonite wastewater.

The composite heavy metal adsorbent Zeoforce 583 was jointly developed in collaboration with Associate Professor Hasegawa from Kanazawa University Graduate School and industry-academia partnerships. Existing adsorbents are expensive and required changing agents for effectiveness against various heavy metals, but Zeoforce 583 can form a heavy metal adsorption layer by mixing with harmless construction waste and other materials in trace amounts. Zeoforce 583 can adsorb and detoxify composite heavy metals using a single agent. This composite heavy metal adsorbent Zeoforce 583 simultaneously triggers reduction reactions, adsorption reactions, co-precipitation reactions, and calcium compound reactions with its main raw materials to achieve chemical stability, and it is a high-performance heavy metal adsorbent that incorporates harmless minerals and chemicals that irreversibly adsorb and render insoluble. The addition rate of Zeoforce 583 is 3% to 5%, and it has the ability to strongly adsorb and render insoluble arsenic and other heavy metals simultaneously; when forming an adsorption layer, the addition rate should be set after confirming safety through column tests and other methods. Zeoforce 583 has received very high evaluations in various consultant competitions.

Zeoforce 835 is a product jointly developed by Associate Professor Hasegawa from Kanazawa University Graduate School and industry-academia collaboration. Typically, conventional solidification treatments require multiple agents tailored to specific heavy metals when dealing with complex heavy metal mixtures. However, Zeoforce 835 can sufficiently solidify complex heavy metals, such as those found in construction waste and contaminated soil, with just a small amount of a single agent. The addition rate of the solidifying agent is also minimal, making it very economical.

By adding a small amount of the easy-to-handle mineral-based powder coagulant Ultra Separate HC to turbid water and stirring, the contaminants strongly coagulate and precipitate while the flocks settle, purifying the water and making it transparent. The coagulation and sedimentation speed is in seconds. The addition rate of the coagulant is also one-fourth of conventional types, and the amount of flocks generated is less than one-third of the usual, reducing the turbidity of the treated water to between 1 and 3, and the contaminants to around 5, resulting in remarkably clear water. It also demonstrates astonishing effects with just a small amount added for the purification of lake water quality.

The power consumption is less than half that of conventional electrostatic precipitators. A stable low-voltage current can be obtained, allowing for the collection of sub-micron particles and demonstrating excellent removal capabilities for dioxins. We developed a high-performance electrostatic precipitator and obtained a patent in June 2006. Using this electrostatic precipitator is very economical as it can reduce dioxins without the need for slaked lime or activated carbon. We are currently seeking companies for technical assistance contracts. This invention enables stable discharge from the flat electrode by providing an optimal gap distance. The discharge electrode has a blunt angle or a shape close to it, making it resistant to corrosion and capable of maintaining a stable high current over the long term.

Grand Solid is a permeable dust control surface improvement material made primarily from PS ash, hexavalent chromium suppression cement, and gypsum. Grand Solid has high early strength and can maintain a stable ground for a long time with a low addition rate. Its granulated structure improves water retention, suppresses dust generation, prevents soil loss due to wind, and offers excellent permeability, allowing for good drainage and quick use of the ground after rainfall. Surface improvement with Grand Solid is effective at a low addition rate, making treatment costs very low and economical. While conventional surface stabilizers use separate granulation agents to create a granulated structure to improve permeability, the permeable dust control surface improvement material Grand Solid can achieve granulation of the surface through mixing.

The leachate from the final disposal site contains a high amount of unburned carbon derived from organic matter and incineration ash, and often does not lose color even after the addition of coagulants. In such cases, the concentration of dioxins does not significantly decrease. As a countermeasure, the Fe-DS system is effective. By using a combination of ferrous iron, caustic soda, and Ultra Separate S-DS for coagulation, very clear treated water can be obtained. This treated water has a neutral pH and can meet the environmental standards for dioxins, including the river discharge standards. In examples of dioxin wastewater treatment, the concentration of dioxins can be reduced from 30 pg-TEQ/L to below 1 pg-TEQ/L after treatment.

The device is low-cost and has inexpensive running costs. The hemihydrate gypsum produced by the hemihydrate gypsum device can be used as a raw material for solidifying agents for soft ground improvement, construction sludge improvement, construction soil improvement, and dredged soil improvement. We are also developing solidifying agents that utilize hemihydrate gypsum.

Fluorine in gypsum is more difficult to immobilize than fluorine in soil, but by using supermagnetite, it can be immobilized below environmental standards.

• Other analytical equipment

Crushed and separated waste gypsum boards can be heated at over 120°C for a certain period, resulting in the production of semi-hydrated gypsum through water and hydration reactions. If a generator is mounted on a 4-ton unic truck, processing can be done immediately. The produced semi-hydrated gypsum can be stored by packing it into flexible containers. Semi-hydrated gypsum serves as an excellent solidifying agent when mixed with lime, cement, and other materials. Solidifying agents can be produced on-site for solidification treatment. Technologies for addressing fluoride in gypsum and suppressing hydrogen sulfide generation have also been established. Consulting services for the recycling of waste gypsum boards into solidifying agents that immobilize fluoride and suppress hydrogen sulfide generation are available nationwide in Japan. Each project costs 525,000 yen (excluding consumption tax).

A three-dimensional water flow stirring and sedimentation device that can achieve three-dimensional water flow stirring using a general mixer has been patented! This is the first of its kind in the world. In general sedimentation processes, the coagulant dissolves and sedimentation occurs due to the rotational water flow generated by the mixer. Most people feel that the stirring efficiency is weak when it is actually in operation. Three-dimensional water flow stirring involves using a standard mixer to create a special structure in the water tank, where the flow in the center moves from top to bottom, while the flow along the sides moves from bottom to top, creating a circulating water flow. By utilizing three-dimensional water flow, clear treated water and well-formed flocs can be obtained in a short time. We also offer consulting services for improving the stirring efficiency of your sedimentation device or developing a sedimentation device tailored to your needs, starting at 525,000 yen (including tax) per project.

The "Ultra Solid Reactor," a high-speed reaction solidification device for sludge, is capable of effectively handling not only sludge treatment but also the insolubilization of heavy metals in construction-generated soil and the decomposition of dioxins. In general construction machinery mixers, the contact time between the treated material and the insolubilization agent is short, which can reduce the insolubilization effect. The Ultra Solid Reactor can set the stirring time to at least one and a half minutes, allowing for better mixing and higher insolubilization efficiency. We will provide optimal original designs tailored to the specific treatment applications.
