In this position the cake will not crack under pressure and complete dependable filtration is assured. Practically every kind of liquid from light alcohols to heavy resins can be filtered in a Sparkler Filter. Filters can be designed and constructed for any particular type of fluid to be filtered. Steam jacketed models where required and brine jacketed models when cooling is necessary. Tanks and working parts are made in a range of materials including stainless steel, mild steel, bronze, nickel, monel, or rubber lined steel. Explosion proof motor equipment used when required. Filter plates are available in two depths, deep plates for liquids carrying a large percentage of solids; shallow plates for liquids carrying only a small percentage of solids, the latter providing a larger filtering area within the same size tank. Sparkler Filters are equally efficient for continuous or intermittent operation. Complete recovery of product is obtained by "wa'sh t h r o u g h " or "blowdown" of cake without removal from filter. T h e Sparkler patented scavenger plate acts as an auxiliary filter with independent control valve, filtering each batch down to the "last drop," leaving n o hold-over. Sparkler Horizontal Plate Filters are made in a range of sizes from the small laboratory pilot plant models to the standard plate models of 50 G.P.H. to 5000 G.P.H. Our engineers are ready to cooperate in solving any problem of filtration. Write E. S. Anderson, Industrial Sales Dept.
In the recovery of naphtha and benzol solvents at the Bayer Aspirin plant Sparkler Horizontal Plate Filters are installed in the processing
line.
