Raw water pump: Provides water volume and pressure to the pretreatment unit.
Quartz sand filter: the use of quartz sand interception, precipitation, inertial action and adsorption to reduce the content of suspended solids in water, while some bacteria, viruses are also removed with the suspension.
Activated carbon filter: The pressure vessel is filled with activated carbon filter material, the particle size is 0.8-2.0mm, and the physical adsorption of activated carbon is used to remove organic matter, colloid and part of heavy metal ions, especially chromogenic substances in water. At the same time, activated carbon can effectively adsorb residual chlorine in water to reduce the residual chlorine content in tap water and improve the taste of water.
Ion softener: reduce the content of calcium and magnesium ions in water and prevent fouling of membrane system.
Precision filter: Filter activated carbon powder and particulate impurities to protect the membrane system from contamination.
Multi-stage pump: Provides water and pressure for back-end membrane system operation.
RO membrane system: a device for desalting and purifying salt water under the action of pressure difference, which can effectively remove inorganic salts, bacteria, viruses, pigments, heat sources, heavy metal ions and pesticides, fertilizers, detergents, colloids and other pollution in water.
