 The size of the auxiliary parts depends on the area of the filter and the type of usage.Rotary vacuum filters are flexible in handling variety of materials therefore the estimated solids yield from 5 to 200 pounds per hour per square foot.For pre coat discharge, the solid output is approximately 2 to 40 gallons per hour per square foot.Filtration efficiencies can also be improved in terms dryness of filter cake by significantly preventing filtrate liquid from getting stuck in the filter drum during filtration phase.
