Before treating the sewage, the microfilter should remove the pollutants and coarse particles in the water. A2.1 Classification of filtration processes
Magnetic filtration processes can generally be divided into two categories according to the magnetic properties of the pollutants contained in the raw water: potential emulsion
iron pollution
virtual pollution
cold pollution
400-60G
a) The main impurities are magnetic impurities. For example, steel wastewater can be directly filtered into the magnetic filter: if it is necessary to remove some floating impurities, it should be treated with coagulation first, and then magnetic filtration; b. If the main impurities are non-natural floating impurities or ions, such as printing and dyeing wastewater, papermaking wastewater, axle and type wastewater, heavy metal ion wastewater, etc., it is recommended to use a coagulant or combined iron and oxygen co-precipitation method to treat it first, and then magnetic filtration.
