some of the well water as drinking water sources, water use will appear in the well of yellow rust phenomenon, how to do?
many of my friends reacted well water yellow rust, which is what causes it, then how should we do it?
because the wells of iron excessive levels of manganese. Iron and manganese in underground had almost simultaneously (well) water, higher iron content in water, water has a smell of iron affect the taste of water. Iron water pipe can produce rust, laundry stain appears yellow or brown stains, iron will precipitate Fe2O3 iron bacteria grow, blockage of tubing, sometimes red water. The high manganese content and high iron content of the water in a similar situation, such as colored water, smell, taste, the household appliance may contaminate a brown or black, or washing clothes will blackish gray spots stains. my countrys "drinking water health standards" (GB5749-85) provisions to this end, the iron content 鈮?.3銕?/ L, manganese content 鈮?.1銕?/ L, more than the standard raw water is subject to iron and manganese removal process. Iron manganese content is too high for a long time drinking water will seriously affect their health, strong production equipment corrosion.
Available iron and manganese removal filtration system, it is the main principle purification: well water after aeration, iron (manganese) begin to oxidize in water, when the water filtered through a layer of manganese sand filter, since the filter chemistry and iron (manganese) bacteria filter surface (poly Bacillus bacteria embroidery, ferrous irons Ka bacteria, iron bacteria and unicellular microorganisms rust coat) biochemical action begins to occur in the filter layer biochemical reactions, physical entrapment of catalytic oxidation and adsorption action, interaction of these processes can greatly accelerate the oxidation of iron in water (Mn), the curing and removal to achieve the desired results.
household drinking water Tips: How well water purification
purify well water, well water according to the situation in different places, such as fluorine-containing groundwater generally Loess Plateau is too high, Custer landscape groundwater generally calcium is too high (commonly known as NOx), and some ground water containing iron and manganese is too high, local conditions vary greatly, well water purification process in very different ways. In short treatment must be targeted, water quality testing should be carried out beforehand, then targeted purification treatment based on test results. Currently these treatments are relatively mature. In addition to the above outer remove excessive water minerals, but also generally well water turbidity of purification,Household water purifier is a good choice, the choice of which the physical filtration, the choice of primary filter sand filtration tank, a filter may be selected intermediate PP cotton core, filtration ceramic core, one can choose a deeper hollow filter ultrafiltration filtration precision of up to 0.01 UM, bacteria and viruses can be filtered out.
Through the above description, you are sure to have well water safety knowledge to understand it. If you want to know more small drinking water safety knowledge, we pay more attention to stop it.
