In the treatment of ore wastewater, the commonly used super -speed flocculant is polymerized aluminum chloride (PAC). PAC is an efficient flocculant that can be used for fast solidification and suspension, sediments and organic matter in the wastewater in the flocculation ore wastewater.
The chemical formula of polymer aluminum is [AL2 (OH) NCL6-N] m, where the value of N and M depends on the formula and preparation method of specific products. It is a polymer compound composed of aluminum chloride and hydraulic aluminum ions, which has good flocculation performance and the ability to adapt to different water quality conditions.
When using PAC as a flocculant for ore wastewater treatment, it usually adds it to the wastewater in the form of liquid or solid, and reacts with pollutants in the wastewater through stirring or mixing. The PAC can quickly condense and flocculate the suspension and organic matter in the wastewater, forming larger particles, which is convenient for subsequent precipitation and solid fluid separation steps.
It should be noted that when using PAC for mining wastewater treatment, the appropriate PAC products should be selected according to the characteristics and processing requirements of the specific wastewater, and the correct operation is performed according to the instructions provided by the manufacturer. At the same time, the processed wastewater should be discharged or further processed in compliance to ensure that the relevant environmental standards and regulatory requirements are met.
