  • 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.
  • Does aluminium sulfate and poly-aluminum chloride affect coagulation process?
  • In this study, the effectiveness of aluminium sulfate and poly-aluminum chloride was evaluated at different pH values and coagulant dosage in order to find optimal operational conditions for low to high turbidity waters. The influence of lime, as a coagulant aid, on coagulation process was also studied.
  • What are the different types of hydrolyzed aluminum?
  • As mentioned above, the chemical species of hydrolyzed aluminum can be divided into three types: Ala (instantaneously reacted, i.e., Al monomers, dimer, and trimer), Alb (reacted within 120 min, i.e., Al 13 ( AlO 4 Al 12 ( OH) 24 ( H 2 O) 12 7 +) ), and Alc (no reaction, i.e., Al polymer molecular weight normally larger than 3000 Da).
  • Why is polyaluminium chloride used in aquaculture?
  • The role of polyaluminium chloride is to increase the soil moisture content, inhibit the formation of soil crusts, as well as increase water infiltration. Used in aquaculture. The addition of PAC coagulant can precipitate and remove a large amount of organic matter in the water body. Would like The Quotation?
