Anionic polyacrylamide application areas:

1. The coal washing plant selects polyacrylamide for coal slurry precipitation and tailing residue filtration. Please choose anionic polyacrylamide, nonionic polyacrylamide and cationic polyacrylamide.

2. Please use anionic polyacrylamide and nonionic polyacrylamide for the occupational wastewater. For the treatment of paint wastewater, the traditional method is to directly coagulate the mixed wastewater, the management effect is not ambiguous, the effluent water quality is unstable, and it is difficult to reach the discharge standard.

3. Dairy products occupational liquid biological treatment, sludge treatment, please select cationic polyacrylamide.

4. Electroplating wastewater contains cyanide oxide treatment using anionic polyacrylamide, nonionic polyacrylamide, low cationic polyacrylamide.

5. Copper ore mining tailings wastewater treatment uses anionic polyacrylamide, low cationic polyacrylamide, nonionic polyacrylamide.

Specific use of anionic polyacrylamide:

1. Granular polyacrylamide flocculant cannot be directly added to sewage. It must be dissolved in water before use, and its aqueous solution is used to treat the sewage.

2. The water that dissolves the granular polymer should be clean (such as tap water) and not sewage. Water at room temperature can be used, generally no heating is required. When the water temperature is lower than 5 ° C, the dissolution is very slow. The water temperature progresses and the dissolution rate accelerates, but above 40 °C, the polymer will accelerate degradation and affect the application effect. Generally tap water is suitable for formulating polymer solutions. Strong acid, strong base, high salt water is not suitable for formulation.

3. The selection of the concentration of the polymer solution is recommended to be 0.1%-0.3%, that is, 1 g-3 g of polymer powder is added to 1 liter of water.
