(kitchen ､ toilet ､ bath ､ laundry ､ etc.) 3) There are many functions in one tank. (anaerobic, aerobic, filtration, disinfection) 4) ｢ Johkasou ｣ can treat wastewater as same quality of sewerage systems. （ BOD removal ratio ≧ 90%, Effluent BOD ≦ 20mg/L ）
Johkasou system (K-HC-T) anaerobic disinfecti on aerobic filtration BOD <20mg/L 4 Kitchen Toilet Bath Laundry BOD 200mg/L Airlift Pump
Johkasou system(K-HC-R) BOD <20mg/L 5 Kitchen Toilet Bath Laundry BOD 200mg/L Airlift Pump
Johkasou system(KJ) BOD <20mg/L 6 Kitchen Toilet Bath Laundry BOD 200mg/L Airlift Pump Dinitrification 2NO - + 5(H 2 ) → N 2 +2OH - + 4H 2 O Nitrification NH4-N → NO 2 -N → NO 3 -N
