Manganese sand filter to produce water for half an hour what to do? Many towns and industrial and mining enterprises in China use groundwater as water source.However, there is an excess of iron in groundwater in many areas,Its content is generally 2-16mq/L range.'Automatic iron and manganese removal filter' overcomes the human operation,Various problems caused by backwashing,Give full play to the special features of fully automatic work,Therefore, it has incomparable superiority in other iron removal devices,The iron content of groundwater after treatment is ≤ 0.3 mg/L,National GB5749-85 quality standards for drinking water.In addition to iron and manganese in water,Make the oxygen in the air two-valent iron,Oxidation of manganese at two prices,Generate Fe (OH) 3,Manganese dioxide,According to the content of iron and manganese in water,Jet aeration or hollow multi-face ball aeration are selected.Filter with first-class or multi-stage manganese sand filter,Can meet the processing requireme

What is the RO film? 2.Principle of reverse osmosis: \ r first understand the concept of 'penetration.Penetration is a physical phenomenon.When two kinds of water containing different salts, such as separated by a semi-permeable film, it will be found that the water on one side with less salt content will penetrate through the membrane into the water with high salt content, the salt contained does not penetrate, so that the salt concentration on both sides is gradually merged to equal.However, it takes a long time to complete this process, also known as penetration pressure.However, if a pressure is added on the water side with high salt content, the result can also stop the above penetration. The pressure at this time is called penetration pressure.If the pressure increases again, it can penetrate in the opposite direction, while the salt is left.Therefore, the principle of reverse osmosis salt removal is to apply more pressure than natural penetration pressure in salt-containing water (such as raw water), s
