Primary Mechanism Greywater flows through a sludge tank to settle solids, then passes through four 500L IBC tanks arranged at a height to allow gravity flow. Each tank contains a reed bed that biologically breaks down organic pollutants (COD reduced to 20-100 mg/L, DO > 2). Two small 0.25 HP pumps circulate water as needed. Treated water is stored in a 1000L IBC tank.
