PORTIONS OF THE BODY OF FILTER MATERIAL ARE ONSTREAM AND WHICH PORTIONS ARE OFFSTREAM.
LIQUIDS ARE CONTINUOUSLY FILTERED THROUGH A PORTION OF A FILTER MEDIUM SUCH AS SAND WITH SIMULTANEOUS REGENERATION OF OTHER PORTIONS OF THE FILTER MEDIUM. THE RAW LIQUID PASSES FROM A VERTICAL DISTRIBUTOR HORIZONTALLY THROUGH A VERTICAL FILTER BED IN A SINGLE FILTER CHAMBER WHILE ANOTHER PORTION OF THE FILTER BED IN THE SAME FILTER CHAMBER IS OFFSTREAM. THE OFFSTREAM FILTER MATERIAL IS REMOVED FROM THE BOTTOM AND THE MATERIAL THAT HAS BEEN FILTERED OUT IS REMOVED THEREFROM, WHEREUPON THE FILTER MATERIAL IS RETURNED TO THE TOP OF THE SINGLE CHAMBER, WHERE IT AGAIN FILLS THE SPACE FROM WHICH IS WAS REMOVED. SEPARATE FILTRATE COLLECTORS ARE PROVIDED WHICH ARE SELECTIVELY PLACED IN COMMUNICATION WITH AN OUTLET THEREBY TO DETERMINE WHICH

摘要:
A multi-component liquid filter is provided having at least two filter elements. One of the filter elements has an increased effective surface area defined by, for example, a pleated surface, to provide an increased filtering surface area. In addition, another one of the filter elements can have a flat surface to minimize the filtering surface area of the element. In one embodiment, the multi-component liquid filter has at least two generally cylindrical filter elements arranged concentric relative to a common axis. One of the filter elements can have a circumferential filtering surface having an increased effective surface area and another one of the filter elements can have a constant radius circumferential filtering surface to minimize the filtering surface area of the element.
摘要:
A filter with a horizontally fed filter chamber having loose bulk material as the filter medium has a wall on the upstream side and downstream side to hold back the loose bulk material in the filter chamber. The filter chamber includes a compressed air-lift pump disposed inside of the filter chamber for pumping the loose bulk material from a bottom area of the filter chamber, through a bottom lifter connected with a stand pipe to an upper rinse chamber, and a hopper disposed at a bottom of the filter chamber having entrance slots and surrounded by a chamber that is provided with a rinse water inlet tube connected to a raw water chamber.
