Mechanical filtration equipment, also known as pressure filters or filtration tanks, serves as the pretreatment unit for water purification systems and is a vital component of water treatment equipment. Depending on specific customer requirements, the tank materials can be FRP (Fiberglass Reinforced Plastic), steel-lined rubber, or stainless steel. As water purification equipment, mechanical filters are classified based on the filtration media used. The filter media can include natural quartz sand filters, multi-media filters, activated carbon filters, manganese sand filters, and ion exchangers, among others. Mechanical filters, as water purification equipment, have different primary functions depending on the media used. These functions include filtering out suspended solids and mechanical impurities, removing organic colloids, eliminating color from water, reducing residual chlorine, removing ferrous ions (divalent iron) from water, and softening water quality.
