12 Shengming water purifier price The water purifier has ultra-filtration water purifier and reverse osmosis water purifier,And there are water purifiers with different water supply,Different filter configurations can also lead to different prices.It is recommended to purchase a suitable water purifier according to your own water demand and the water quality requirements after purification.First, the water purifier is also called water purifier.According to the composition structure of the filter element, it is divided into RO reverse osmosis water purifier and UF membrane water purifier, energy water purifier and ceramic water purifier.RO reverse osmosis water purifier is standard with Grade 5 filtration,That is, the first level is pp cotton,For primary filtering,Mainly filter sediment, rust, a large particle visible to the naked eye, the second level is granular carbon, which has a strong interception effect on organic matter and inorganic colloid in the water,The third grade has the functions of deodorizat

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
