• History    • Company Profile    • News News August 2006 Pneumapress® Receives Filter Order for the Pulp and Paper Industry Pneumapress Filter Corporation has been awarded a contract to supply a Model 19 multi-module filter for a US based pulp and paper facility. The filter installation is scheduled for early 2007. The filter will be used to remove residual char and calcium carbonate from a hot green liquor stream at 190F and wash the resultant filter cake to remove sodium and potassium carbonates. Pneumapress® filters are available in single module or multi-module filter chamber construction with capacities from 1 to 10,000 GPM. Operation is both simple and fully automatic. The filtration cycle begins when the filter plates close to form the filter chambers. Each set of plates sandwiches a woven filter media belt, which separates the chamber into an upper and lower section. Slurry is pumped into the upper section of each filter chamber and a solid cake is formed above the filter media belt as the filtrate liquid passes through the belt. Once the cake is formed, wash liquid is pumped through the cake to remove any unwanted material from the cake. Compressed air or gas is then used to dry the cake by forcing the remaining liquid in the cake through the filter media. At the end of the filter cycle the filter chambers are opened and the filter media belts automatically discharge the dry cakes into a mixer, tote box, or onto a conveyor.
