Why 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 .

What are the different types of chlorine derivatives?

For gainful utilisation of chlorine, the business has portfolio of chlorine derivatives like Stable Bleaching Powder (SBP), Polyaluminium Chloride (PAC), Chlorosulphonic Acid (CSA), Chlorinated Paraffin Wax (CPW), Calcium Chloride (CaCl), Aluminium Chloride (AlCl) and Chloromethane (CMS).

What is Vikram/kanpac polyaluminium chloride?

VIKRAM/KANPAC Polyaluminium chloride is aluminium based inorganic coagulant designed for clarification of wastewater & paper sizing. Unique product exceed the clarification performance of conventional chemical used for wastewater treatment. It produce denser solid which more suitable for better dewatering.

Does initial concentration of aluminum chloride affect the yield of Al B?

As observed in Fig. 1 (a–d), the effects of initial concentration of aluminum chloride, basicity ratio, reaction temperature and time curves were steep slope and curvature, which revealed that the yield of Al b content in the PΑC species was very sensitive for these factors.

What are the synthesis parameters of aluminum chloride hexahydrate?

The synthesis parameters were concentration of aluminum chloride hexahydrate (0.4 to 0.8 M), basicity ratio (2.0 to 2.4), reaction temperature (60 to 80 °C) and time (180 to 360 min). The performance of PΑC for water treatment was also investigated. The monomeric, medium polymeric and colloidal species of PAC were determined by Ferron test method.

Is Pac better than aluminum sulfate & aluminum chloride for removing turbidity & nom?

Moreover, the performance of synthesized PAC was also very much higher as compared with aluminum sulfate and aluminum chloride for removing turbidity and NOM from synthetic water samples. The coagulant dose and the lime required of synthesized PAC were reduced more than two folds relative to aluminum sulfate and aluminum chloride doses.
