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

What kind of anion exchange resin does vc and vc ether use? Ion Exchange Chromatography (IEC) is the stationary phase of Ion Exchange agent,A chromatography method based on the difference in the binding force between the component ions in the mobile phase and the equilibrium ions on the exchange agent for reversible exchange.On 1848,Thompson et al found ion exchange during the study of exchange of alkaline substances in soil.In the 1940s S,Polystyrene ion exchange resin with stable exchange properties has emerged.On 1950s,Ion exchange chromatography enters the field of biochemistry,Applied to the analysis of amino acids.At present, ion exchange chromatography is still a common chromatography method in the field of biochemistry,It is widely used in the separation and purification of various biochemical substances such as amino acids, proteins, sugars, nucleotide, etc.The commonly used ion exchange agents are: Ion exchange cellulose, ion exchange
