Selecting the Right Coagulant for Wastewater Treatment Systems
Comparing the efficacy of Aluminium Sulphate, Polyaluminium Chloride (PAC), and organic polymers in turbidity reduction.
Industrial effluent management requires choosing the right coagulants. Choosing between inorganic salts like Aluminium Sulphate (alum) or PAC depends heavily on raw water pH, organic load, and settling time constraints.
Alum remains the most cost-effective solution for municipal systems with stable pH levels. However, Polyaluminium Chloride offers superior floc formation in low-temperature or fluctuating pH environments. Testing with jar tests is highly recommended before choosing your coagulants.
