Clean the wastewater from the combined treatment septic tank with the reclaimed water treatment tank and reuse it for toilet flushing!

Reclaimed water is situated between "tap water," which is used for normal daily life, and "sewage," which is discharged during daily activities. The reclaimed water utilization system cleans wastewater and reuses it for purposes such as toilet flushing. This system is being adopted in areas with discharge regulations and among those who are highly concerned about environmental protection. Additionally, when combined with on-site power generation facilities, it can be utilized even during power outages. Its implementation is increasing in convenience stores and other locations as a lifeline during disasters. *Note that a maintenance contract is required for the reclaimed water utilization system. 【Benefits】 ◎ Fully automated ◎ Clean water quality ◎ Effective use of limited water resources ◎ Contributes to achieving SDGs ◎ Reduction in water and sewage disposal costs ◎ Low running costs and easy maintenance ◎ Subsidy programs may be available in some regions *For more details, please refer to the PDF materials or feel free to contact us.

basic information

【Water Treatment Methods】 ■Combined Treatment Tank - Wastewater from buildings is first treated in a combined treatment tank. - The wastewater is purified through sedimentation separation and microbial treatment. ■Tertiary Treatment Tank - Wastewater treated in the combined treatment tank is further purified in the tertiary treatment tank. - Using a highly efficient carrier, advanced microbial treatment and biological filtration are performed, and fine suspended solids are removed through sedimentation separation. ■Reclaimed Water Treatment Tank - In the reclaimed water treatment tank, wastewater is purified to below "BOD 5mg/ℓ" and above "transparency 100" through biological carrier treatment and biological filtration, followed by decolorization and deodorization using ozone. - The wastewater, which has been highly treated with ozone and is colorless and odorless, is stored in a reservoir and supplied as toilet flushing water via a pump. ■Activated Carbon Filtration Tank - An activated carbon filtration system is combined to prepare for potential deterioration of water quality due to increased water usage. In emergencies, purification is carried out with the activated carbon filtration system to ensure the quality of the treated water. *For more details, please refer to the PDF document or feel free to contact us.
