  • Can polyaluminum chloride be used in water treatment?
  • In this study, synthesis and speciation of polyaluminum chloride (PAC) for application in water treatment was investigated using a colorimetric speciation method. It was possible to produce stable preparations of PAC solutions in which a relatively stable cationic polymer predominated.
  • Is polyaluminum chloride a good coagulant for water treatment?
  • Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water [ 6 ].
  • How does poly aluminum chloride affect sludge production?
  • PAC benefited the aggregates of sludge flocs. PAC caused more EPS remained in sludge cells. Solubilization, hydrolysis, acidiogenesis, and methanogenesis were inhibited by PAC. Alb and Alc were the contributors to the decreased SCFA production. Poly aluminum chloride (PAC) is accumulated in waste activated sludge at high levels.
  • Why are aluminium based polymers used in water treatment?
  • These shortfalls in the use of alum have led to the synthesis of improved, aluminium-based polymers, which have been used extensively, over the few last decades, for treating water due to their high efficiency at lower dosages, and wider pH and temperature application ranges ( Sahu & Chaudhari 2013 ).
