How to determine the flow rate of the multi-media filter backwashing pump? The strength of the reverse wash is 10L/m2 * s, which is expressed by q. The backwashing flow is equal to the backwashing strength q multiplied by the filter area of the equipment, so that the pump flow can be obtained.1. multi-media filters use one or more filter media to pass water with high turbidity through granular or non-granular materials of a certain thickness at a certain pressure, in order to effectively remove suspended impurities and clarify the water, the commonly used filter materials include quartz sand, anthracite coal, manganese sand, etc., which are mainly used for water treatment, turbidity removal, softening water, and pre-treatment of pure water, the turbidity of the effluent can reach less than 3 degrees.2. the filter materials commonly used in multi-media filters mainly include quartz sand, anthracite coal, manganese sand, etc. the filtering accuracy of different filter materials is different to meet the requi
