Ammonia in wastewater is nitrified in the water environment by microorganisms and changes into nitrate-nitrogen or nitrite-nitrogen that adversely affects human beings. Moreover, to decompose and treat separated ammonia, we provide separation recovery equipment and separation decomposition equipment, incorporating the catalyst technology of Nippon Shokubai.

Methane gas generated from anaerobic biotreatment is converted into a stable fuel by separating concentrations of CH? and CO? in biogas.
Based on our BMB tower technology, we have developed a system for separating and adsorbing CH4 and CO2, which reduces global warming gases. In activated sludge method, aerobic treatment has been employed widely for treating water quality. However, many disadvantages posed by the aerobic treatment have increased applications of anaerobic treatment with methanogens. Compared to aerobic treatment, surplus sludge is decreased markedly with biological treatment, recovering and utilizing CH4 as a carbon neutral product, saving energy and substantially contributing to prevent global warming.
With conventional systems, the quality of fuel recovered from discharged CH4 is low as its recovery is mixed with CO2. However, the BMB absorber recovers high-quality fuel by effectively recovering CH4 and CO2 separately.
