 Manganese sand filter backwash frequently destroys its active membrane layer surface, reducing the effect of removing iron and manganese filter sand filter; and repeatedly backwash has no obvious benefit, so the best manganese sand filter Do frequent backwashing. So how long can be called a backwash is "frequently" mean? Manganese sand filter used in addition to iron and manganese filter. After generating a long iron scale, affecting heat transfer, can corrode equipment. Use of manganese sand filter backwash function to achieve the purpose of purification to remove. However, due to the activity of the membrane structure manganese sand filter surface is relatively loose, easily damaged, so generally do not backwash air, as long as the pressure does not affect the output on the line. When the pressure reaches a certain time manganese sand pavement installation height, simple backwash it, did not need to engage in air backwash, it was destroyed because manganese sand filter membrane surface testing method, reestablished need a lot of time. So thorough security manganese sand filter backwash out once a quarter is enough, each time not too long backwash control in 5-15 minutes just fine. Manganese sand is made of natural manganese sand or manganese ore as raw material, crushing process, repeated screening, processed into different contents of manganese sand filter. The appearance of rough, brown sand manganese normal maintenance, with good iron and manganese functions, is the ideal product for water supply and drainage industry. As a form of manganese sand filter manganese manganese dioxide mainly based, users can be noted in the different processing purposes. Currently, in addition to iron ore using natural MnO2, the principle there are two kinds: one is the role of the so-called membrane, manganese sand surface has a strong layer of oxidation. Another is antiferromagnetic manganese ore itself catalyze the water divalent iron into trivalent iron catalysis, then ferric kilohertz manganese ore particles adhered to the surface and thus play a purpose other than iron. Natural manganese dioxide can oxidize water divalent iron to trivalent iron to precipitate manganese sand is removed, the water clean. Manganese dioxide dissolved oxygen in water is oxidized into heptavalent manganese oxide. Seven manganese oxide in water and then divalent iron into trivalent iron. Natural manganese ore is a strong oxidant, can play in water stock iron oxidation. Hydrochloric acid can be dissolved in water application can not acidic. Some manufacturers and individuals online propaganda that natural manganese sand slightly soluble in hydrochloric acid is no scientific basis, manganese sand filter Product Details: manganese sand pavement installation height, Chifeng manganese sand, manganese sand filter Song Xin rose from Gongyi City Song Xin filter Industrial Limited.
