Industrial water filters are mechanically cleaning. Since the impurities and residue retained mechanical filter elements. Requirements for the purification of water with time and therefore tougher filtering becoming more and more quality to meet the requirements. Filtration process in some filters may be based on the fact that the particles of oil just stick to the singular surface of the filtering layer. If sort filters by type of environment is responsible for cleaning the original solution, we obtain the following list: membrane, wire, fabric, alluvial, granular. For industrial water treatment uses the boot filters, and if you want to waste water from oil and oil it uses the following technique.
Waste water that you want to clean, supplied by pipeline to the filter canister which is filled with special crushed particles with a diameter of 0,5-1,8 mm. After passage of this layer load of water extracted particles of oil, sand and other solids, and then purified water is drained through a pipeline from filtration unit. Filter bed during filtration is gradually saturated with petroleum products, so you need it from time to time change. Apply such filters to purify water, which was already pre-cleaning. Finally, the purified water can be used in industrial water supply enterprises. Besides filters, which we have just considered, for cleaning of industrial water, there are other types of filtration plants. Consider some of them: – open – water that passes through this filter should be transparent, and the concentration of oil in it should not exceed 1-1,5 mg / l – a floating charge – in connection with a high adhesion to the oil products they use, and for separating oil-water emulsions – coalescing – consolidation of small emulsified droplets of oil into larger ones.
