We need to do living water filtration and purification in our project living quarters. What kind of equipment do you need? How much, approximately?
Water purification, its precision is relatively low, generally 0.1 M (10-7 m), only removing suspended solids (silt, rust etc.) and microbe, and not very good filter of heavy metal and organic agricultural chemical pollution, but retained the mineral water, boiling water is still a scale.2 is the use of soft water, the principle of ion exchange resin, calcium and magnesium ions adsorption water exceed the standard by ion exchange, thereby reducing the hardness of the water, the tap water without boiling water scale, but not very good to remove bacteria, impurities and organic pollution.
There is no limit to this, and what kind of effect you want will have the same amount of money,OneTypes of purified waterOn the market, purified water is generally divided into three categories: one is pure water, two is soft water,Three is pure water.
2, the filter core and filter water purification is filtered through the filter at all levels. At present, the common filter material has:PP cotton, common filter, filtering accuracy of 5 m (5 * 10-6 m), can only remove particulate matter. Activated carbon, is an adsorption type filter core, can absorb water odor, some residual chlorine, heavy metals and so on.Hollow fiber ultrafiltration membrane is, filtering accuracy of 0.01 M (10-8 m), can remove microorganisms, heavy metal and organic part.3 RO is a membrane, reverse osmosis membrane, filtering accuracy of 0.0001 m (0.1 nm) can effectively remove bacteria, viruses, and other heavy metals. RO membrane is the filter membrane used for purifying purified water.And ceramic filter, KDF film and so on. The filter element is usually used in combination with several filter membranes. Because the filter core is contaminated, it must be replaced for a certain period of time. PP cotton generally use 3~6 months to be replaced, the other element usually takes 1~3 years to replace every year, replace the filter costs about 100 yuan.
Pure water, its purification degree is high, generally 0.1nm (1 nanometer, namely 10-10 meters), almost filtered out all impurities in water, and the water taste pure. Some purification equipment in the manufacture of pure water, and then add a level of science, to increase mineral content, and make water weak base (pH value is slightly greater than 7), known as weak alkaline mineral water, the actual still belongs to this category of pure water. It should be explained that the minerals that people need in the water want to be retained, while the heavy metals and chemical pollution that are harmful to people want to be filtered out, but in water purificationIt is difficult to solve the problem when both are retained at the same time (such as purified water), or simultaneously filtered (e.g. pure water), hoping to retain one and remove it. From the point of view of purification, the use of pure water, which can filter almost all kinds of pollution, may be better. The loss of minerals can be supplemented by other methods, such as drinking milk (120 times the amount of calcium in the water of the same amount of water).
