Johkasou: Japan’s Advanced On-site Wastewater Treatment
Tank for Purifying
Johkasou is a sophisticated treatment system that uses anaerobic, aerobic and disinfectant processes to render blackwater (that bears human excreta) and/or greywater (from kitchens and sinks) relatively harmless and clean. Johkasou system was introduced in Japan in 1911 and developed rapidly in 1960s to meet the high demand for clean water.
Difference between Septic Tank and Johkasou
In many countries, septic tanks as anaerobic digesters are still built for domestic wastewater treatment. Johkasou uses Japan’s original method, which combines aerobic, anaerobic, filtration, and disinfection treatments
