Iron and manganese in the ground (well) water almost at the same time, when the water contains high iron, the water has a fishy smell, affecting the taste of water, as paper, textile, printing and dyeing, chemical and leather delicate production water, will reduce product quality, iron-containing water can make production appliances rust spots, washing clothes will appear yellow or brown stains, iron precipitates Fe2O3 will grow iron bacteria, blocking pipes, and sometimes appear red water. It has strong corrosion ability to production equipment.

Manganese sand filter is a filter media using quartz sand or manganese sand as filler. It is conducive to removing impurities in water. It also has the advantages of small filtration resistance, large specific surface area, strong resistance to acid and alkali, and good resistance to pollution.

The unique advantage of manganese sand filter also lies in the self-adaptive operation of the filter by optimizing the design of the filter media and the filter. The filter media has strong self-adaptivity to the raw water concentration, operating conditions, pre-disposal process, etc., i.e. the filter bed automatically forms the upper sparse and lower dense state during filtration, which is conducive to ensuring the effluent quality under various operating conditions, and the filter media is fully dispersed during backwashing with good cleaning effect.

The sand filter can effectively remove the suspended matter in the water, and has obvious removal effect on the pollutants such as colloid, iron, organic matter, pesticide, manganese, bacteria and virus in the water. And it has the advantages of fast filtration speed, high filtration precision and large dirt interception capacity.

It is mainly used in the fields of electric power, electronics, beverage, tap water, petroleum, chemical industry, metallurgy, textile, paper making, food, swimming pool, municipal engineering and other various process water, domestic water, recycled water and deep disposal of wastewater.

Manganese sand filter treatment method

Water with high iron and manganese content is generally treated by oxidizing the dissolved divalent iron or divalent manganese into insoluble trivalent iron or tetravalent manganese compounds respectively under the action of catalyst (such as manganese sand), and the backwashing function of manganese sand filter is used to remove the purification purpose.

Manganese sand filter technical requirements

The natural manganese sand used for iron and manganese removal in groundwater should be mainly in the form of manganese oxide. Natural manganese sand filter media with manganese content (MnO2) not less than 35% can be used for removing iron and manganese from groundwater; natural manganese sand filter media with manganese content of 20%-30% is only suitable for removing iron from groundwater; manganese ore sand with manganese content less than 20% is not suitable; natural manganese sand varieties that have been scientifically tested or used in production and proved to have good effect of removing iron and manganese are preferred As filter media.

Manganese sand filter application scope

1、It is used for industrial water, domestic water and municipal water supply system which requires the turbidity of the effluent to be ≤5mg/L and can meet the drinking water quality standard;

2、Removal of suspended matter and solids in industrial sewage;

3、It can be used as pretreatment equipment in ion exchange softening and desalination system, and coarse filtration equipment for industrial water supply with low water quality requirement; and used in swimming pool circulating treatment system, cooling circulating water purification system, etc.
