Filters play a crucial role in purifying water. They can remove impurities such as sand, silt, rust, and some bacteria and viruses from raw water. For example, in a municipal water treatment plant, the filter helps to make the water safe and clean for domestic use by separating out solid particles and harmful microorganisms.

Filter cartridges play a crucial role in maintaining the purity of the electroplating solution. During the electroplating process, various impurities such as particulate matter, metal oxides, and residues from previous plating operations can be present in the solution. The filter cartridge can effectively remove these solid impurities. For example, tiny metal particles that have fallen off the anode or cathode during the electroplating process can be trapped by the filter. This ensures that only clean electroplating solution is in contact with the workpiece, which is essential for obtaining a smooth, uniform, and high - quality plating layer.
