Septic tanks with integrated filters provide an efficient solution for primary and secondary wastewater treatment. They are advanced clarification systems—highly stable, efficient, and cost-effective—and are widely used for treating domestic blackwater and similar types of discharge.
The configuration of the tank, featuring an internal cone and high-surface-area filter media, forces wastewater to pass through a retention zone. The slowdown of the flow promotes solid sedimentation, while the filtration action retains organic matter. At the same time, a complementary anaerobic digestion process transforms suspended solids, producing an effluent with a low concentration of dissolved and colloidal solids.
