- What is poly Aluminium chloride (PAC)?
- In the vast field of water treatment, the role of chemicals in ensuring the purity and safety of water cannot be overstated. Among these, poly aluminium chloride (PAC) has emerged as a cornerstone in both potable water and wastewater treatment processes.
- Does pH affect the performance of polyaluminum chloride (PAC)?
- The performance of PAC was dependent on pH. The synthesized PΑC was efficient coagulant for water treatment. The present work was aimed to synthesis of polyaluminum chloride (PAC) using calcium oxide as a basification agent and optimization of process parameters on the yield of medium polymer species in PAC.
- What is high-purity poly-aluminum chloride (PACL)?
- Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high-purity PACl are needed.
- Can PAC be prepared from aluminum chloride solution?
- PAC can be prepared from aluminum chloride solution with the titration of various basification agents such as calcium oxide [ 16, 21 ], sodium hydroxide [ , , ] and sodium aluminate [ 25 ].
