1 Kubota Johkasou Model HS-P
Kubota Johkasou Model HS-P Household Wastewater Treatment System 5・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

6 Term and conditions of design
Average daily wastewater 53gal/P/D (200L/P/D) Influent BOD 200mg/L Effluent BOD 20mg/L ≥ BOD removal rate 90% ≤

Treated Water Tr>20cm ≒BOD<20mg/L
