Quartz sand filter and manganese sand filter

Quartz sand filter is sand and manganese sand filter simple filter, then what is the difference between them, there is a user asks, quartz sand filter can instead of manganese sand filter, by analyzing their respective role under the principle of: a, quartz sand filter

quartz sand filter filled with quartz sand filter material as the name implies, quartz sand is mainly by retaining filter to intercept the water sediment impurities, such as quartz sand is different from the ordinary sand, because quartz stronger hardness, particles can be fine, if using ordinary quartz sand, because ordinary sand after backwashing, is easily broken, the passage of time long sand used more serious. And although manganese sand packing density is big, but there is no Shi Yingqiang manganese sand strength, so used for filtering impurities such as intercepting sediment effect certainly not as good as quartz sand.

2, manganese sand filter

manganese sand filter, also known as iron manganese filter, mainly is for the use of the iron and manganese ions, he mainly by intercepting + adsorption to filter the iron and manganese in the water. Iron and manganese ions after aeration oxidation, manganese sand can be filtered to remove.

excessive amounts of iron and manganese water is generally used in the oxidation of the dissolved state under the action of bivalent iron or bivalent manganese oxide respectively into insoluble ferric iron or quadrivalence mn compounds, using the adsorption of manganese sand filter iron and manganese in addition to the filter can be removed. He reaction of the chemical oxidation process is as follows:

4 fe2 + + O2 h2o + 10 = 4 fe ( 哦) 3 + 8 h + mn2 + + O2

2 + 2 h2o mno2 = 2 + 4 h +

three filter, quartz sand and manganese sand filter operation parameters

overall, quartz sand filter and quartz sand filter operating conditions, are 3 - feed water pressure 4 kg, at room temperature, the filter tank routine for stainless steel and carbon steel lining plastic material, or epoxy anticorrosive processing. The main difference is that the filtration velocity, quartz sand filter, maximum flow rate can be up to 20 m/h, and manganese sand filter maximum velocity of 10 m/h, so deal with the same water, quartz sand filter tank to a smaller diameter, filled with quartz sand packing does less. From the cost of the filter material, manganese sand filter material cost is higher, and higher bulk density. So if with manganese sand filter to replace the quartz sand filter from the economy also is very not bargain. And filter from the original, quartz sand filter can't instead of manganese sand filter, because the effect of quartz sand filter in addition to iron and manganese is far from manganese sand filter in addition to good effect of iron and manganese.
