Title: Countercurrent washing of gravity filters - with automatic intermediate washes with small quantities of water increasing service life
IPC: B01D35/16
Filed: 1976-09-01
Abstract: Washing granular filter beds in gravity filters by periodical counter-current flow of filtrate from a filtrate receiver provided for the purpose, incorporates intermediate washes with smaller quantities of filtrate between large washes with the whole quantity of filtrate in the receiver. The operation is automatic, the washes being initiated by the press. drop across the filter bed increasing as the bed becomes blocked with sediment. A filter in which the process is used incorporates a filter chamber with a cover and a filtrate accumulator, above the filter chamber. The filter chamber contains the granular filter bed on a screen and a filtrate receiver below the screen. The filtrate accumulator is open at the top and works at a constant level during the filtering period. A pipe connects the filtrate receiver with the bottom of the filtrate accumulator. An inlet pipe connects a feed vessel above the filter with the upper part of the filter chamber. A washing pipe is connected to the cover of the filter chamber and to one end of an invertsion bend above the level of the liq. in the filtrate accumulator. A down pipe connects the other end of the bend to a sump below the accumulator. A siphon break pipe is connected to the inversion bend and dips into the accumulator, where it divides into two branches with outlets at different levels. A bistable rocking lever system closes and opens alternately the upper outlet. When it is closed the countercurrent wash is carried out with the whole quantity of water in the accumulator, above the lower outlet. When it is open, intermediate wash is carried out with the smaller quantity of water above the upper outlet. In other forms, the double-pipe rocking lever system is replaced by a pipe of variable outlet height and a float; valves operated by remote control; a magnetic valve actuated by a pressure switch or a relay or a level operated switch; or an air feed system. The facility to carry out intermediate washing with smaller quantities of water increases the length of time for which the gravity filter can be in service, without increasing the quantity of water necessary.
