Filter selection begins after a company determines the required level of filtration or filtered water quality; decides whether filtrate will be disposed or reused; identifies how much space is available; calculates the amount of capital available to purchase, operate, and maintain the system; decides whether the system should be automatic or manual; and considers any pertinent water conservation requirements.
Water Treatment Filter size is determined by flow rate and the amount, size, and type of solids to be removed. Particle sizes and filtration levels can be determined by filtering water and solids through varying sizes of filter paper and measuring the total solids content of filtered water.
Solids remaining in Membrane Water Treatment Systems will be the same size or smaller than the last filter paper used and will indicate which filter media opening size to use. (A filter manufacturer or laboratory can be hired to perform this procedure.) The quantity of solids in water or wastewater can be determined by a laboratory analysis of total solids; flow can be determined from plant records or an in-line flow meter.
The following equation is used to calculate solids loadings (how quickly a filter will load with solids): solids (lb/h) = flow (gal/min) x total solids (ppm) x (8.34/60/1,000,000).
After solids loading, Water Treatment Filter, and filter media opening size have been determined, the amount of time required before cleaning, or back-washing, should be calculated, and the fate of filtrate waste must he determined.
