Poly aluminum chloride(PAC) is a type of inorganic flocculants. The flock can form rapidly with fast sedimentation rate and low cost. The water clarity rate is better than aluminum sulfates. PAC can give good result in a wide range of pH (5-11).
Application Field
1, cleanse of water from river, reservoir and groundwater.
2. cleanse of industry water, waste water treatment and sludge dewatering.
3. Sewage treatment and sludge dewatering
4. Starting materials of cosmetics.
5. Sizing agent in paper industry
6. Carrier of catalyst.
