The standard flow rate of municipal tap water is generally between 0.2 and 0.6 meters per hour. The specific value will be adjusted according to the actual situation in different regions. In order to meet the residents' demand for high-quality drinking water, water treatment equipment is often used to treat municipal tap water. The filter element is one of the important components of water treatment equipment. After a period of use, the filter element will be blocked by impurities in the municipal tap water, and it is necessary to use backflushing to clean the filter element regularly.
