Usage principles: 

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

2. The water used to dissolve granular polymers should be clean (such as tap water), not sewage. Room temperature water is sufficient; heating is generally unnecessary. Dissolution is very slow below 5℃. Increasing the water temperature accelerates the dissolution rate, but temperatures above 40℃ will accelerate polymer degradation, affecting the effectiveness of the solution. Generally, tap water is suitable for preparing polymer solutions. Strong acids, strong alkalis, and water with high salt content are not suitable for preparation.

3. The recommended concentration of the polymer solution is 0.1%–0.3%, which is 1–3 g of polymer powder added to 1 liter of water.

4. Dosage: Generally, the dosage of polyacrylamide per ton of dry mud is about 2-4 kg. The actual dosage must be adjusted according to the actual site conditions.

   
   

Precautions: 

1. Determine the optimal model and dosage of the product through small-scale testing.

2. The product should be prepared into a 0.1% (solid content) aqueous solution, preferably using neutral water without salt.

3. When dissolving in water, sprinkle this product evenly into the water while stirring, and heating appropriately (<60℃) can accelerate the formation of a solution.

4. This product is hygroscopic and should be stored in a sealed container in a cool, dry place at a temperature below 35℃.

5. Avoid spilling solid products on the ground to prevent the ground from becoming slippery after the products absorb moisture.
