Process Flow
This pre-packaged wastewater treatment system is engineered for treating sewage from kitchens, toilets, and laundry facilities. Kitchen wastewater is pre-treated with a grease trap, while toilet flushing sewage must first pass through a septic tank. The collected wastewater flows into the Johkasou system, where it undergoes biological treatment through anaerobic, anoxic, and aerobic phases. Pollutants are significantly reduced before the water is discharged, and excess sludge is periodically removed using a suction truck every 3–6 months.
