Tap water (or other) to primary and secondary water treatment water treatment, tertiary water treatment to fine treatment, membrane separation system to sterilization, user
Technical principle:
　　Primary treatment: the main removing coarser particles and impurities in water, commonly used method is to use a certain specifications of quartz sand, manganese ores, etc.
　　Secondary treatment: adopt high quality coconut shell activated carbon, by using the principle of filtration and adsorption, eliminate peculiar smell, residual chlorine, suspended solids and organic impurities.
　　Tertiary treatment: the sodium ion exchange resin, the replacement of the water calcium and magnesium ions.To reduce the hardness of water.The south water quality soft, usually do not use.
　　Fine filtration: commonly known as security filtering, often using hollow fiber filtration precision for 5 um, continue to purify water quality, prolong the service life of and protection.
　　Membrane points out: choose one to two membranes, including microfiltration (MF), nanofiltration (NF), ultrafiltration (UF) and reverse osmosis (RO), etc., on craft according to the user to select the type of membrane, the requirement of the water quality of reverse osmosis can effectively in addition to salt and organic matter.
　　Through the multi-stage purification of water quality, fully meet the drinking water hygiene requirements.In order to further ensure the quality of the whole system, in the final stage, add sterilization, disinfection to ensure that the pipeline of the drinking water hygiene requirements.
