Ferromanganese elements in the water are invisible, only iron content in excess of the time will emerge yellow look, and therefore whether there is manganese sand filter removing iron and manganese is not apparent to the naked eye, a lot of people It will have such doubts - whether manganese sand filter has not removed the elements of iron and manganese in the water it? So is there any way to know whether there is manganese sand filter element removal of iron and manganese in the water? Here to tell us about how we can know whether manganese sand filter plays a role in removing iron and manganese. A look at the color of water. As mentioned above too much water ferromanganese element, then it will happen on the color change from colorless to yellow, manganese sand filter water filtration, you can see the color of the water quality is restored colorless and transparent, to determine manganese sand filter really play in addition to the effect of iron and manganese. 2 to see the quality manganese sand filter. Manganese sand filter capable of removing iron and manganese, the manganese and iron are cleared to where exactly? The answer is to dispose of manganese sand filter. So the longer the manganese sand filter usage time, the more removed the elements of iron and manganese, and the weight of manganese sand filter also will be more severe, use a sand filter iron and manganese year will increase 5%, manganese It will increase by 20%. So we can weight up to judge manganese sand filter manganese sand filter is played effect of removing iron and manganese. 3 Check the water quality index is subject to change. Before using manganese sand filter, it must be through water quality testing have found the need to use manganese sand filter, so we can detect water quality after filtration sand filter manganese manganese sand filter to know whether the real play in addition to iron the effect of manganese, manganese sand filter price concessions, sponge filter manufacturers, manufacturers of quartz sand, manganese sand filter manufacturers in the most professional. Manganese sand has a higher fire-resistant function, industry general quartz sand often divided into: general manganese sand, manganese sand refined, high-purity manganese sand, sand and microsilica molten manganese. General general quartz sand manganese sand that SiO2≥90-99% Fe2O3≤0.06-0.02%, what refractoriness 1750 ℃ ??manganese sand role? , The appearance of some large particles, the appearance of a yellow cysts. Size scale of 5-220, the user needs size production. Main use: metallurgy, Mexico silicon carbide, glass and glass products, enamel, steel, water filtration, sodium silicate, chemicals, spraying noisy occupation. Refined manganese manganese sand, also known as sand, SiO2≥99-99.5% Fe2O3≤0.005%, high quality natural quartz sand, Britain at the end carefully selected, fine fine manganese sand processing. Particle size 1-0.5mm, 0.5-0.1mm, 0.1-0.01mm, 0.01-0.005mm, according to user needs processing. Purpose: to make glass, refractory materials, exercise ferrosilicon, metallurgical flux manganese sand backwash strength is how much? , Ceramics and manganese sand how to use? Abrasive materials, quartz sand casting appearance, etc., used in the construction of its strong acid etching medium capacity, extracting acid and acid of concrete mortar. Refined manganese sand SiO2≥99-99.5% Fe2O3≤0.02-0.015%, selection of high quality ore processing disorder. Size with a 5-480 scale projects, according to user needs production, the appearance of white or crystals. Main use: high-grade glass, glass manganese sand, refractory materials, smelting stone, precision casting, grinding wheel and other materials. (Mm is millimeters) Deyang manganese sand, manganese sand Which cheaper price? , Song Xin manganese sand filter Price (certified merchants) are provided by Gongyi City Song Xin Industrial Co., Ltd. filter.
