The quartz sand in the automatic water filter multimedia filter is used to remove particles and suspended solids. A layer of anthracite can also be added to treat influent with high suspended particles. Finely crushed garnet can also be used for finer filtration. The multi-media filter mainly uses more than two kinds of media as the filter layer. In the industrial circulating water treatment device, it is mainly used to remove impurities in the sewage.
1. River water treatment, because the river water mainly has relatively high sediment content, especially in the rainy season, and there are relatively many organic impurities in the water, mainly because the river water dissolves some rotten branches and weeds. Therefore, the multi-media filter is generally matched with quartz sand and activated carbon. The sediment in the water and the impurities in the organic matter are absorbed in the water. If the content of quartz sand and organic impurities is compared, it is best to connect the quartz sand filter and the activated carbon filter in series. run.
2. Groundwater treatment. Groundwater mainly contains high iron and manganese content. Multi-media filters generally choose manganese sand filter material. Manganese sand filter material has the ability to remove iron and manganese efficiently. Generally, since the hardness of manganese sand is not very high, it can be added The quartz sand filter material improves the passing rate of water. If the water contains sediment and other impurities, it is recommended to add quartz sand to the bottom of the manganese sand filter for interception and filtration.
3. Advanced purification treatment of sewage, especially textile wastewater, printing and dyeing wastewater, mechanical processing wastewater, papermaking wastewater, medical wastewater, food wastewater, etc., due to its high chroma, high content of suspended solids, and organic additives. The multi-media filter generally uses quartz sand and activated carbon, and the quartz sand traps the filter box activated carbon to absorb impurities such as sediment in the effluent water, improve the transparency of the water, and remove the odor in the water.
