SS filter material for iron and manganese removal

SS filter materialMainly used for removing iron and manganese from groundwater, purifying surface water, deeply purifying tap water, filtering and reverse osmosis pretreatment, purifying circulating water in swimming pools, and treating domestic and production wastewater. Due to the porous structure and good adsorption capacity of SS filter material, it has significant effects on the treatment of domestic and industrial wastewater.The main mechanism is the combined effect of adsorption filtration and flocculation sedimentation.

1、 The adsorption and filtration function of SS filter material

SS filter materialIt has a porous structure, rough surface, a porosity of over 50%, a large specific surface area, and high surface energy. It has strong physical filtration and chemical adsorption effects on iron, manganese, and various pollutants in water. SS filter material is used for removing iron from drinking water,mainThe characteristic is that there is no need to cultivate an active filter membrane, and the initial effluent can meet the standard. This feature has opened up a simple and feasible new path for the removal of iron and manganese from groundwater, which can be considered an innovation. The reason why it is possible to remove iron without cultivating an active filter membrane is mainly because SS filter material is a porous particle with a large adsorption capacity and a long filtration adsorption section. Although it may not immediately meet the standard for manganese removal, it takes less time than manganese sand and quartz sand.

2、 The flocculation and sedimentation effect of SS filter material

The main components of SS filter material are silicon, iron, aluminum, and carbon, which account for more than 90% of the filter material and are beneficial for purifying water quality by removing iron and manganese. Especially, the iron and aluminum salts formed by the dissolution of iron and aluminum in water are good coagulants, which have flocculation and sedimentation effects on iron, manganese, and various pollutants in water.

3、 SS filter material is easy to backwash

The backwashing process can be completed with only one water volume, and the filter material does not harden. After more than ten years of practical application, SS filter material has been proven to have a positive effect on removing iron and manganese. Its outstanding feature of being able to remove iron from the initial operation has also been repeatedly verified. SS filter material has a good effect on removing iron and manganese.

It should be noted that during the use of SS filter material, the raw water for iron and manganese removal must be aerated to ensure sufficient filter layer thickness and sufficient backwash space. Rinse the SS filter material. The filter material needs to be backwashed once every three days.
