1, ultrafiltration machine
Fine ultrafiltration is a traditional water dispenser technology, filtering material is activated carbon, PP cotton and other materials as a filtration medium, can only remove the water sediment, large particles, etc.;
Microfiltration and ultrafiltration is a drinking water dispenser technology that has emerged before and after the Shanghai Expo, the use of organic or inorganic material The filter membrane is made of organic or inorganic materials. Ultrafiltration can filter bacteria, rust, colloids and other substances in the water, but can not filter metal ions. By the way, the hospital dialysis is this kind of, but the material purity is higher;
Fine-filtered water dispenser even if the early 1990s things, as long as it is the county above the area, the water plant water and pipeline network water supply purity can reach and exceed the level of the fine-filtered. But if the township users are recommended to consider buying or installing ultrafiltration, reverse osmosis equipment. Township water supply system is too poor, I am currently involved in the township project is either drinking water source and drainage outlet are together, or system management is chaotic, water treatment chemicals either do not add, or add indiscriminately. Fine filtration drinking fountain production costs are very low, so generally speaking the purchase price should be 500-600 yuan / unit is more reasonable.
Microfiltration and ultrafiltration drinking fountains are now mainstream, helping to improve the taste of drinking water (kitchen installation), reduce home pipe network sedimentation and sediment (intake mains installation). If the water quality is good in your area, an ultrafiltration water dispenser is sufficient after filtration. Ultrafiltration water dispenser cost is low, the purchase price of 800-1200 yuan / unit is more reasonable.
2, reverse osmosis water purifier
Reverse osmosis water dispenser is the trend, theoretically removes all impurities in the water, including bacteria, heavy metals, salt, the actual will be a small amount of residue, but basically almost the same as pure water. Even if you take water from the cesspool, after reverse osmosis are directly drinkable.
Reverse osmosis water is recommended to boil before drinking (equipment with a period of time will be bacterial overload), and need to pay attention to, long-term drinking reverse osmosis water but on the contrary, is not good for health. It is recommended to drink tap water or mineral water at a certain frequency. In addition, home water dispenser production rate is low, the general production of 1 cubic meters of water need to consume 6 cubic meters of tap water, water-scarce areas to use with caution.
Reverse osmosis water dispenser cost is actually not high, but the market price is high, I probably looked at, generally in the 3500-7000 yuan / unit, taking into account the need for marketing products, late maintenance and total profit on sales of a single product than the total industrial products have a few orders of magnitude of difference, is also considered to understand the manufacturers, but the price is definitely too high, I think the sales price of 2,000-3,000 yuan / unit! It is almost the same.
