- When conducting wastewater treatment using activated sludge, it is very important to create a suitable growth environment for the activated sludge. In addition to nutrients such as nitrogen and phosphorus, mineral components are also necessary for the growth of activated sludge. - Even if nitrogen and phosphorus nutrients are sufficient, if the activated sludge continues to be unhealthy, there may be a deficiency in minerals. - "Active Clean Team Plus" is a multi-supplement that is balanced and formulated in an easily absorbable form with various minerals that are often lacking in activated sludge.

The "Bioreactor System (Soil Bacteria Activated Sludge Method)" is based on the activated sludge method. It utilizes humic substances produced by soil bacteria microorganisms that inhabit the natural environment to efficiently purify wastewater and suppress odors. It is resilient to load fluctuations, stabilizes effluent quality, and improves sludge characteristics (settling and filtration). Additionally, it reduces maintenance costs and enhances the working environment. 【Features】 ■ Improved water quality ■ Reduced odor in wastewater treatment ■ Resilient to load fluctuations with stable effluent quality ■ Improved sludge characteristics (settling and filtration) ■ Reduced maintenance costs and improved working environment *For more details, please refer to the PDF materials or feel free to contact us.

• Water Treatment

The "Rotating Child Raia" is a wastewater treatment device that can accommodate various effluent water qualities through combinations with other processing methods. It efficiently decomposes BOD components in wastewater by densely retaining microorganisms in the packing material and supplying air while rotating the aeration pipe, which helps to detach excess sludge and prevent clogging of the packing material. It can handle wastewater from a wide range of industries, not only the food industry but also chemicals and pharmaceuticals. 【Features】 ■ Capable of high-load operation ■ Strong against fats and oils ■ Generates little sludge ■ Only requires management of dissolved oxygen (DO) without special management ■ Requires less power for the blower *For more details, please refer to the PDF document or feel free to contact us.

• Water Treatment

The "Doric membrane separation activated sludge method" utilizes a membrane in the liquid for solid-liquid separation, eliminating the need for a sedimentation tank. This method maintains a high concentration of microorganisms in the aeration tank, drastically shortening the treatment reaction time and significantly reducing the size of the treatment facility compared to conventional methods (long aeration times). Furthermore, because it produces highly treated water, it can be reused as utility water without the need for additional equipment such as tertiary treatment devices or filtration systems. We also offer a maintenance support service called the "Membrane Guarantee System" to ensure stable operation of the membrane over the long term. 【Features】 - Simple system - Achieves both space-saving and ease of handling - No sedimentation tank required - Drastically shortens treatment reaction time - Reusable as utility water *For more details, please refer to the PDF materials or feel free to contact us.

• Turbid water and muddy water treatment machines

We would like to introduce our "Methane Fermentation Reactor System." At the bottom of the methane fermentation tank, hydrolytic bacteria, acid-producing bacteria, and methane-producing bacteria gather, forming a high-density state of granular sludge known as "granules." This allows for high-load operation by evenly passing organic wastewater in contact with the bacteria. Unlike aerobic treatment, organic matter is removed by 85% to 92% in an anaerobic state without oxygen, during which biogas (methane and carbon dioxide) is generated. This biogas has the potential to be used for energy recovery. Unlike aerobic treatment, the growth rate of sludge is very slow, contributing to a significant reduction in sludge disposal costs. 【Features】 ■ The growth rate of sludge is very slow compared to aerobic treatment. ■ Contributes to a significant reduction in sludge disposal costs. ■ Reduction in running costs. *For more details, please refer to the PDF document or feel free to contact us.
