What is the filter principle of efficient filter? 1.Interception effect: When a particle of a certain particle size moves near the surface of the fiber,The distance from the center line to the surface of the fiber is less than the particle radius,Dust particles will be intercepted by filter fiber and deposited.2.Inertia effect: when the mass of particles is large or the speed is large,It is deposited by collision on the surface of the fiber due to inertia.3.Diffusion effect: the particle Brown with small particle size moves strongly and easily collides on the surface of the fiber.4.Gravity effect: when particles pass through the fiber layer,Deposited on the fiber due to gravity settling.5.Electrostatic effect: both fibers and particles can bring charge,Generate electrostatic effects that attract particles,And suck the particles onto the surface of the fiber.As more dust is captured,The filtering efficiency of the filter layer also decreases,And the resistance increases;When a certain resistance value

Principle of multi-media filter A multi-media filter uses one or more filter media,At a certain pressure, water with high turbidity is passed through granular or non-granular materials of a certain thickness,So that the process of effectively removing suspended impurities to clarify water,The commonly used filter material has quartz sand,Anthracite,Manganese sand, etc,It is mainly used for removing turbidity from water treatment,Softened Water,Pre-treatment of pure water, etc,The turbidity of the effluent can reach less than 3 degrees.The top floor of the bed consists of the lightest and thickest grade material,The most heavy and fine grade materials are placed in the lower part of the bed.The principle is to filter by depth--The larger particles in the water are removed on the top floor,The smaller particles are removed in the deeper depths of the filter medium.So that the water quality reaches the standard after coarse filtration.The equipment is pressure type,The principle is that whe
