We all know that most of the wastewater from mineral processing comes from the sewage produced in the flotation process of mineral processing. The volume of mineral processing wastewater is particularly large, and the content of solid suspended impurities is high. The wastewater contains various heavy metals and chemical agents. If it is directly discharged and pollutes the water source, these heavy metals may accumulate in human organs through the food chain. In severe cases, it may even cause organ diseases and cancer in the human body. Therefore, the treatment of mineral processing wastewater is highly valued. Polyacrylamide is a high-molecular polymer that can rapidly cause solid suspended matter in mineral processing wastewater to coagulate into flocs. After sedimentation and other treatments, the water will become clear. The treated wastewater can meet the discharge standards or the clarified water can be recycled in other places. This not only protects the environment but also makes full use of water resources.
Which polyacrylamide is used for the treatment of mineral processing wastewater?
We all know that there are many types of polyacrylamide, a wastewater treatment chemical, such as anionic polyacrylamide, cationic polyacrylamide and nonionic polyacrylamide. So, how should we choose when treating wastewater from mineral processing? In fact, due to the differences in mineral types and regional water quality during the mineral processing, the water quality of the wastewater produced during the mineral processing also varies. Generally, anionic polyacrylamide is often used to treat mineral processing wastewater, but the molecular weight of anionic polyacrylamide ranges from 400w to 2500w. Therefore, to accurately find the appropriate specification of polyacrylamide for mineral processing wastewater treatment, we will all choose to conduct wastewater sample tests. Through water sample experiments, we can determine which specification of polyacrylamide to use. This not only ensures the treatment effect of mineral processing wastewater but also reduces the usage of wastewater treatment chemicals.
