• Filtration Equipment

This is an introduction to a case where a liquid membrane was introduced into the wastewater treatment facility for animal and vegetable oil processing. During the expansion of the factory, consideration was given to the discharge river, resulting in the modification of the wastewater treatment facility to a membrane separation activated sludge method. Although it involves high-concentration wastewater containing oil and fat, by combining floating separation equipment with the membrane separation activated sludge method using liquid membranes, clear treated water is consistently obtained. This treated water is effectively utilized for snow melting in winter and for irrigation of young plants in summer. Excess sludge is dewatered and then incinerated. The waste heat generated during incineration is used for heating water, which is effectively utilized for cleaning water within the factory. [Case Study] - Location: Niigata Prefecture - Type of wastewater: Animal fat processing wastewater - Treated water volume: - 95m³/day - +5m³/day (dewatering filtrate) - Operation: Since June 2009 *For more details, please refer to the PDF document or feel free to contact us.*

• Water treatment equipment

This is an introduction to a case where a liquid membrane was introduced into livestock (cattle and pig) wastewater treatment facilities. In Ugo Town, Akita Prefecture, a farming and livestock circulation system has been established to raise safe, secure, and delicious Ugo beef by feeding cattle with additive-free feed made from a mixture of rice straw and rice bran, and utilizing cattle manure for rice cultivation. At the core of this system is the compost center, which produces high-quality organic compost called "Ugo Yuki" in the compost fermentation building and properly treats cattle and pig urine in the urine treatment facility. The adoption of the liquid membrane enables stable discharge of clear treated water. The treated water is used as agricultural water in the irrigation channels where it is released. 【Case Details】 ■ Location: Ugo Town, Akita Prefecture ■ Wastewater Type: Cattle and pig urine ■ Treated Water Volume: 24.2 m³/day ■ Operation: From April 2001 (expanded in April 2006) *For more details, please refer to the PDF document or feel free to contact us.
