Manganese sand filter iron and manganese removal equipment stainless steel tank body automatic backwashing

Product Core Structure

The manganese sand filter uses natural manganese sand filter material as the core filling medium, relying on the catalytic oxidation characteristics of manganese sand itself to achieve water purification. The raw water enters the tank, and the divalent iron and manganese in the water are catalytically oxidized on the surface of the manganese sand, converting into insoluble iron oxide and manganese oxide precipitates. Combined with the physical retention effect of the filter layer, the precipitates, suspended solids, and colloidal particles are retained inside the filter material layer. The filter layer of this device has a large specific surface area, low filtration resistance, excellent acid and alkali resistance, and strong anti pollution ability. The optimized filter material filling and tank structure design enable the equipment to have adaptive operation capabilities, and have good adaptability to fluctuations in raw water concentration, changes in operating conditions, and differences in pre-treatment. Under filtration conditions, the filter bed will naturally form a stable structure with a sparse top and a dense bottom, ensuring stable effluent quality; When entering the backwashing stage, the water flow flushes the filter material thoroughly, efficiently removes attached impurities, and achieves excellent regeneration and cleaning effect of the filter material. In addition to the function of iron and manganese, manganese sand filters also have significant removal effects on pollutants such as suspended solids, colloids, some organic matter, pesticide residues, bacteria and viruses in water bodies. They have comprehensive advantages such as fast filtration speed, large interception capacity, and stable filtration accuracy.

Core technological advantages

Firstly, dual purification of catalytic oxidation and physical retention. Unlike ordinary quartz sand filtration that only intercepts suspended solids, manganese sand filter material can be used as a catalyst to efficiently oxidize soluble iron and manganese ions in groundwater, solving the problems of yellowing of water bodies and excessive metal ions from the root, and solving the common problem of iron and manganese exceeding standards in groundwater.

Secondly, it has strong adaptability to working conditions. The filter bed can automatically form a layered structure with sparse upper and dense lower layers during operation, and maintain stable effluent even when there are slight fluctuations in inlet water quality; During backwashing, the filter material is fully fluidized, impurities are completely removed, the regeneration effect of the filter material is good, and the filter material replacement cycle is extended.

Thirdly, the material selection is diverse and the anti-corrosion performance is reliable. The shell can be equipped with options such as carbon steel lining, epoxy coating, stainless steel, etc., to cope with various corrosive environments such as groundwater, chemical wastewater, acidic and alkaline water bodies, and the tank has a long service life.

Fourthly, the operation and maintenance costs are low and the operation is convenient. The equipment can be configured with manual or fully automatic control mode, and backwash can be started according to the pressure difference between the inlet and outlet or the set time, without the need for a dedicated person to continuously monitor it; Manganese sand filter material has a long service life, a long replacement cycle, and low overall consumables investment.

FAQ

Q1: What is the core function of manganese sand filter?

A: Manganese sand filters are mainly used for removing iron and manganese from groundwater, while intercepting suspended solids and colloidal impurities in water. Through the catalytic oxidation of manganese sand, the dissolved divalent iron and manganese in water are converted into solid precipitates for filtration and removal, solving the problems of yellowing of well water and excessive metal ions. They are often used as pre-treatment equipment for water treatment systems.

Q2: Are your water filtration products mainly divided into equipment and filter cartridges, and which products are included?

A: Yes, it is.
