What is the difference between single-flow mechanical filter and double-flow mechanical filter? Mechanical filter is also called pressure filter. it is an important part of the pre-treatment and water purification system for pure water preparation. the material is made of steel lining or stainless steel,According to the different filter media, it is divided into natural quartz sand filter, multi-media filter, activated carbon filter, manganese sand filter, etc,According to the water inlet method, it can be divided into single flow filter and double flow filter,It can be used jointly or separately according to the actual situation.The pipe of single flow mechanical filter is simple,Running smoothly.The filtration flow rate is generally 4-50 m/h,The operating cycle is generally 8 hours.The two-stream mechanical filter is equipped with a water inlet device at both ends,There is a water outlet device in the middle.The advantage is that the amount of filtered water is large,High pollution removal capacity,Long run
Is the manganese sand filter really effective for getting iron from well water 10? The iron removal mechanism of manganese sand filter material is by contact oxidation method,Let the Fe 2 in the groundwater enter the manganese sand filter layer together with the dissolved oxygen,Under the contact catalytic action of manganese sand filter layer,Complete the oxidation and interception of Fe 2.In the early stages of filtering,Mainly based on adsorption and iron removal,After a while,The capacity of adsorption and iron removal of filter materials has gradually weakened,The iron content of water after filtration has an upward trend.Meanwhile,The surface of the filter material begins to generate an iron filter membrane with catalytic activity,But the contact oxidation capacity is small,Therefore, in the process of forming the filter membrane, the new filter material,At the same time, it has two functions: adsorption and iron removal and contact oxidation and iron removal.At the later stage, the active iron filter m
