Features of the Equipment

       It is still a pressureless filter basin, with the same basic principle of operation, characterized by:(1) No valves are installed for inlet, outlet, backwashing, or drainage. Both operation and backwashing are fully automated by water pressure. Unlike siphon filter basins, double-valve, or single-valve filter basins, no siphon pipes are needed to replace valves, and no vacuum equipment needs to be set up.

(3) The backwash water tank is located at the top of the filter bed, eliminating the need for a separate flush tank or pump. This reduces the space required and saves on electricity consumption. No operational procedures are required.

(5) Operation and flushing are fully automated by hydraulic control, requiring no operation, management, or maintenance. Only regular maintenance is needed.
