Nearly every industrial manufacturing site requires a source of water for its various processes. Water is used for heating, cleaning, rinsing, cooling or dilution and must always be filtered and recycled. In any given process, water can be contaminated with oil, sludge, dirt or scale and must be filtered or purified before it can be recycled for use again or released to a natural body of water. Mesh Strainers, cloth filters, and filter presses generally remove solids from the water. In applications which use oil for lubrication, oil is removed from water using oil skimmer machines, separators and clarifiers.
