Galvanization, that is, coating one type of metal (usually steel) with a thin layer of another metal (nickel, zinc, chrome, etc.) in order to protect it from corrosion or as a decorative coating. The basis of galvanization is the electrolytic process, when a part or workpiece is immersed in a bath with electrolyte. During production, the electrolyte becomes contaminated with mechanical impurities and precipitates formed as a result of the electrolytic process. Since the electrolyte becomes contaminated, there is a need for its purification. The electrolyte contains acids, metals, and salts of relatively high value, so its reuse is economically justified. The simplest and quite effective way of purifying the electrolyte is the use of mechanical filters. In essence, this process is very similar to water purification, with the difference that the materials used to manufacture the pump and the filtration unit must be chemically resistant. Our company offers both separate chemically resistant plastic pumps (polypropylene, PVDF, PVC) as well as ready-made filtration units . The advantage of a filtration unit, at a relatively low cost, is the presence of all necessary elements to implement the purification process almost immediately, straight out of the box. The filter housing is equipped with Slim 20-inch filter elements. These elements are available to order with different pore sizes — 5-10-25-50-100 µm.
