Polyaluminium Chloride 30% (PAC 30%) Chemical appearance:
Polyaluminium Chloride 30% (PAC 30%) is a yellow or light-yellow powder. It is tasteless, harmless and non-toxic when in contact with humans or aquatic life. The substance dissolves in water with ease and can even absorb water from the atmosphere.
Chemical application and strengths:
-
- Polyaluminium Chloride (PAC) contains positively charged hydroxyl aluminium cations with strong basicity. This characteristic enables PAC to function as an effective coagulant in a wide range of industrial and water-treatment processes.PAC can act as both an organic and inorganic flocculant, allowing industries to use it for industrial coagulation and raw sewage treatment. During these processes, the positively charged aluminium species in the solution interact with negatively charged ions and suspended particles in the mixture. These interactions destabilize and aggregate the impurities, forming larger flocs that operators can remove through filtration or sedimentation.
This coagulation and flocculation mechanism makes PAC useful for sewage treatment, industrial water treatment, and wastewater purification.
Beverage manufacturers and water-bottling companies also use Polyaluminium Chloride to remove impurities from water. Natural water contains various minerals that it collects as it flows through soil and rock. These minerals can affect the water’s taste and quality.
