Groundwater ( Deep well water) In addition to iron manganese technology is introduced
groundwater excess iron manganese formation analysis:
the crust of rock and soil, due to the erosion of carbonate, organic matter of dissolved and ferric iron to iron oxide reduction under anaerobic conditions, make a lot of iron into the groundwater.
the groundwater water treatment equipment technology analysis, deep well water equipment in addition to iron and manganese, iron and manganese equipment adopts advanced iron and manganese removal technology at home and abroad, the well pump pressure filling air suction or compressed air machine, perforated tube hybrid dissolved oxygen, automatic exhaust valve degassing, dissolved oxygen contact oxidation bed filtration perfect combination, such as equipment cover an area of an area small, in addition to iron and manganese well water, groundwater treatment mainly for removing iron and manganese and ammonia nitrogen, harmful material such as sand, scale, and make the processed water quality meet the national drinking water standards. Well water, groundwater treatment at present is mainly iron, manganese, because in our country, high groundwater fe mn content is quite common, in addition to iron and manganese mainly adopts aeration filter, filter filter medium usually use quartz sand and manganese sand, later after precision filter to filter, activated carbon, and after treatment, the water quality can basically meet the national drinking water standards. And ammonia nitrogen is mostly using ultrafiltration and reverse osmosis filtration process, sediment and scale can be used more filter filtration and ion exchange softening devices.
equipment using deep well water, groundwater, in addition to iron and manganese iron and manganese removal technology at home and abroad, the well pump pressure filling air suction or compressed air machine, perforated tube hybrid dissolved oxygen, automatic exhaust valve degassing, dissolved oxygen contact oxidation bed filtration perfect combination, such as equipment cover an area of an area small, in addition to iron and manganese piping is simple, small investment, stable and reliable working performance and so on. Filter in addition to iron and manganese is mainly used for domestic water to remove the bivalent iron and manganese in the water, is the ideal equipment in addition to iron and manganese.
groundwater organic dissolution and ferric iron to iron oxide reduction under anaerobic conditions, make a lot of iron into the groundwater, iron and manganese in the water often exist at the same time, China's regulations on hygienic standards for domestic and drinking water, iron content is 0 or less. 3 mg/L, manganese content is 0 or less. 1 mg/L, long-term drinking water containing iron and manganese high adverse to human body, impact on the textile, paper making, brewing, food and so on product quality, to generate spots, and the corrosion of the equipment, therefore, must carry on the processing in addition to iron and manganese.
the working principle of the filter in addition to iron and manganese:
in the water exist in the state of Fe2 +, Fe2 + ion is easily polluted ion exchange resin, the resin poisoning and reduce the exchange capacity, after heat generated on the surface of iron scale extremely easily, affect the heat transfer and corrosion of equipment, iron excessive amounts of groundwater, or well water, water has peculiar smell. Equipment, in addition to iron and manganese in the use of natural manganese sand MnO2 and the REDOX reaction of Fe2 +, Fe2 + Fe3 + and generate becomes Fe ( 哦) 3 after precipitation, the use of filter backwash function to remove them. Iron groundwater by manganese sand filter layer after aeration, water ferrous iron oxidation reaction can quickly finish in the filter layer, and at the same time will be the iron intercept in the filter layer, so as to complete a full iron removal process. Groundwater after aeration manganese content in the manganese sand filter layer filter, make high manganese hydroxide are attached to the surface of filter material, gradually forming a contact with the catalysis of manganese membrane filter, which makes the water bivalent manganese oxidized manganese removal for a high price.
iron manganese filters filter material selection is very important, he is related to in addition to the ability of iron and manganese, manganese sand of manganese content in 30% generally, so the manganese sand filter ( In addition to iron manganese filters) Can iron out of water, if the content of manganese in 35%, then the manganese sand filter can remove the manganese ion in the water, and then the other one is the filter velocity cannot too fast, the design flow rate of manganese sand filter commonly at about 8 m/h.
