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
Kubota now unveils a package incorporating its advanced water treatment engineering expertise, which has been refined through many years of experience in building water treatment plants. Optimal water treatment solutions are available in locations and in sizes customers require. Kubota’s “plant package” is sure to serve as the key concept of combined wastewater treatment tanks.
Small and Medium Johkasou
This wastewater treatment tank is designed for individual homes and vacation homes to small-scale stores and flats. It is a standard product.
For various uses, including large-scale plants, public facilities and apartment buildings. It is custom-made according to the facility’s demands.
Optional advanced treatment for Johkasou system and the effluent improvement for existing STP. The final treatment for effluent polishing to remove remained SS and BOD from the secondary treatment. By adopting high performance carrier media, compactness has been achieved and the workability has been greatly improved.
