The activated carbon filter for removal of organic compounds in water, colloidal silicon, chlorine (Cl2) on a strong odor, color, heavy metal ion adsorption capacity. The beverage industry use water-purification carbon, can improve the product taste. 
 The activated carbon filter is mainly used for mineral water, all kinds of water craft, swimming pool and other process water purification. With deodorant, odor, to remove the chloride ion and other organic matter. The shell is made of stainless steel or carbon steel, fill water purification activated carbon. 
 Quartz sand filter is the use of quartz sand as filter media under certain pressure, high water turbidity through a certain thickness of the granular and non-grain quartz sand filtration, and the interception to remove suspended solids, organic matter, plastic quality of particles, microorganisms, chlorine, odor, and some heavy metal ions, and water treatment equipment, water clarification. Depending on the water production, to be equipped with different mesh quartz sand (quartz sand particles of different diameters) are used in water treatment turbidity, demineralized water, and the former level of pure water pretreatment effluent turbidity of up to 3 degrees or less.
