<p>A floating media bioclarifier having energy efficient and water conserving backwashing. The bioclarifier includes a filter chamber (12) fluidly connected to a charge chamber (13) adapted for accumulating air. A trigger device (24) positioned between the charge chamber and the filter chamber selectively allows the flow of air from the charge chamber to the filter chamber. The backwash cycle is initiated by the trigger device allowing air to escape from the charge chamber and agitate the floating media (15). Simultaneously, water from the filter chamber flows into the charge chamber. After the trigger device closes, air accumulates again in the charge chamber.</p> |
