In gravity-fed mode water is pumped from the unit (at up to 2,500 gph).
(1) Water is drawn by gravity from a bottom drain and/or side inlet (2). The EstroSieve can be isolated with an optional valve (3). A float (4) regulates the flow-rate into the unit to maintain the artificial water level (5). Water spills over the internal weir (6) and down the removable curved sieve element.

(7) Oxygenated water filters through the sieve. Dirt is lifted off and collects above water level (8). A pump (mounted externally or inside the EstroSieve sump (9)) draws water out and pumps into the BubbleBead Filter (10). Water is returned from the filter outlet (11) to the pond (12) e.g. by a cascade. |
