1 Kubota Johk asou Model HS-P Household Wastewater Treatment System5・7・10 Person Tank

2 “Johkasou” in Japan 8,600,000 units of “Johkasou” placed in Japan Approx.160,000 units of “Johkasou” were installed in Japan in 2008 for domestic use. In 1969, we started development of “Johkasou” That can treat only night soil(flush toilet water) In 1986, we launched new “Johkasou” that can treat both night soil and gray water. Since then, a new high-performance product development continues. Now we manufacture approx. 20,000 “Johkasou” in a year.

3 Price concerning “Johkasou” in Japan “Johkasou” Catalog Price 6,000 ~ 12,000 dollars Construction Cost Including “Johkasou” 7,500 ~ 12,500 dollars Maintenance and Operation cost a year 500 ~ 900 dollars

4 Perspective cross section Effluent Air-lift pump Influent Anaerobic filter tank First chamber Anaerobic filter tank Second chamber Sedimentation tank Contact aeration tank Disinfection tank Blower Remove solids in the wastewater and anaerobic microbe attached to the filer decompose organic matter . Sludge is stored in these tanks Aerobic microbe grows on the surface of contact media in the condition of aeration by blower Suspended solids are settled and supernatant flows to overflow weir
