Double-Wall HDPE Septic Tanks are wastewater pre-treatment units designed for the collection of wastewater, settling of suspended solids, and anaerobic biological processes. They are manufactured from suitable-grade polyethylene with a reinforced double-wall structure.
The tanks can be designed and manufactured according to the required capacity, installation conditions, and project requirements. During the treatment process, suspended solids settle inside the tank and a significant portion of organic matter is decomposed through anaerobic processes. Depending on the system design and required effluent quality, the treated effluent can be directed to subsequent treatment stages or controlled disposal.
