MSABP® : Multi-Stage Activated Biological Process Treatment System

MSABP® is a wastewater treatment technology based on a revolutionary biological treatment process in which a fiber-likeorganism-supporting media provides immobilization of microorganisms in a multi-stage aeration tank.

①Suppresses the generation of excess sludge ➡ Reduces sludge disposal costs; sedimentation pond and sludge return are unnecessary(cost-down, space-saving)

②Absorption of variations in the concentration of raw water (±50%)➡ Facilitates operation and management *1

③Also treats highly concentrated effluent (COD < 50,000mg/L)➡ No dilution treatment required *1

④Also decomposes hard-to-decompose effluent (BOD/COD ≥ 0.15) ➡ Also decomposes surface-active agents, etc.*1

・Treatment of chemical effluent with high COD content (chemical plants, pharmaceutical plants, cosmetics plants, etc.)・Treatment of hard-to-decompose effluent such as antiseptics and insecticides・Reduction in excess sludge from easy-to-decompose effluent such as effluent from food manufacturing plants・Sewage treatment for domestic wastewater・Wastewater treatment under high salt level

•As an effect of the multi-stages, the biota in each tank changes in an orderly manner, thereby forming a food chain.•The fiber-like organism-supporting media provides an environment in which microorganisms remain active and are able to treat highly concentrated effluent and hard-to-decompose effluent.

ELCAT ® : E l e c t r o C a t a l y t i c M e t h o d

The ELCAT® is a composite process that combines an electrolytic tank and a catalytic tank.Effectively decomposes and treats organic matter by changing hard-to-decompose substances into easy-to-decompose substances.

① It is also possible to treat hard-to-decompose organic matter that cannot be removed completely by biological treatment.

② Generates hypochlorous acid by adding salt ➡ More economical than the addition of hypochlorous acid

・Decoloring through decomposition of dye・Industrial wastewater treatment, wastewater recycling・Post-treatment for biological treatment (removal of hard-to-decompose organic matter after biological treatment)・Reduction of dilution water(When diluted to the value which is lower than the criterion value)

•Treatment occurs in two stages by using the electrolytic and catalytic tanks.*3

•Easy-to-decompose intermediates are generated by forming hypochlorous acid in the electrolytic tank and oxidizing the organic matter.•Both the intermediates and surplus hypochlorous acids are sent to the catalytic tank to be gasified and decomposed by means of oxidation-reduction reactions.

The HiPOx® water purification technology is based on the AOP system that utilizes ozone gas and hydrogen peroxide.

①Mixers are located immediately after the ozone gas injection ports, thereby enabling the gases to mix effectively ➡Reduced amount of ozone injection and installation space compared to treatment with ozone alone

②Minimizes the formation of reaction byproducts by means of ozone injection at multiple points (when used in drinking water applications)

Residual ozone gas is separated from treated water using a gas separator.The ozone gas thus separated is decomposed and made harmless using ozone destruction equipment before being discharged.

・Industrial wastewater, Industrial wastewater recycling, ultra pure water recycling, sewage water purification, water treatment, etc.

•Hydroxyl radicals are formed through the addition of ozone gas and hydrogen peroxide to decompose and remove organic matter.
