What are the main applications of PAC?

PAC is primarily used in water treatment for coagulation and flocculation, as well as in paper manufacturing, textile dyeing, and as a food additive for water purification.

How does PAC work in water treatment?

PAC works by neutralizing the charges of suspended particles in water, allowing them to clump together into larger particles (flocs) that can be easily removed through sedimentation or filtration.

What are the benefits of using PAC over traditional coagulants?

PAC is more effective at lower dosages, produces less sludge, has a faster settling time, and works over a wider range of pH levels compared to traditional coagulants like aluminum sulfate.

Is PAC environmentally friendly?

Yes, PAC is considered environmentally friendly due to its lower impact on water quality and the reduced amount of residual sludge it produces compared to other coagulants.

What is the recommended dosage of PAC for water treatment?

The recommended dosage varies based on water quality and treatment goals but typically ranges from 5 to 100 mg/L. It's best to conduct jar tests to determine the optimal dosage for specific conditions.

How should PAC be stored?

Store PAC in a cool, dry place, away from direct sunlight and moisture. Ensure that the containers are sealed tightly to maintain its quality.

Can PAC be used in industrial wastewater treatment?

Yes, PAC is effective in industrial wastewater treatment processes, helping to remove suspended solids, heavy metals, and other contaminants from various types of industrial effluents.

What is the shelf life of PAC?

The shelf life of PAC is typically around 12 to 24 months when stored properly in a sealed container, away from moisture and contaminants.
