Oily fine coal powder and clay suspended matter in coal washing sewage have very strong suspension characteristics in water, so it is difficult to remove substances in water by general natural precipitation method, and coal washing wastewater has high chrominance, high turbidity and high chemical aerobic characteristics. Many customers of coal washing plants are very headache in the treatment of coal washing sewage. Here, Secco Environmental Protection will explain to you how to use polyacrylamide to effectively treat impurities in water and reduce sewage to clean water.
Secco Environmental Protection has found in many experiments that the use of flocculation treatment of coal washing sewage can reduce water consumption costs, and the sewage can recover coal slime to reduce coal damage, and economic benefits can protect the environment, suitable for large and small coal washing plants. There are many customers in the beginning of the use of polyacrylamide when do not know how to select, different regions of different coal mine sewage treatment is not the same, so some may not be clean, this time it is necessary to test the water sample, and then choose the right product. After separating the coal slag in the sewage, the coal slag can be sold, and the water quality after treatment can be recycled again. In the process of coal washing, the PH value of the sewage may be acidic, and the PH value can be adjusted to about 7, and then the appropriate polyacrylamide is used to separate the water and coal slime powder.
