Backwash industrial water filters are installed on water supply pipes in various industries such as power stations, the chemical industry, printing and dyeing, and papermaking. They are mainly suitable for pipes below DN500mm, thus replacing secondary filters and saving costs. They are key equipment for achieving optimized management of the above systems, and are especially suitable for water and power departments with few people on duty.
