Working Principle of quartz sand filter? Raw water usually contains fine particles of dust, rot, starch, cellulose, bacteria, algae and other microorganisms. These impurities form colloidal particles in the Sol state with water, which present settlement stability and polymerization stability due to Brown motion electrostatic rejection, and cannot usually be removed by means of natural sedimentation under gravity, the general raw water pretreatment can destroy the stability of the Sol with the addition of flocculation, make small colloidal particles, and then condense into larger particles, and pre-filter through sand filtration and carbon filtration to remove these particles. Working Principle of groundwater special quartz sand filter it uses quartz sand as the filter medium, and at a certain pressure, the water with high turbidity is filtered through a certain thickness of granular or non-granular quartz sand, effectively intercepting and removing suspended matter, organic matter, gum particles, microorganis
