Get PriceWhat is polyaluminium chloride?
Polyaluminium chloride (PAC) is a pre-hydrolyzed inorganic polymeric coagulant that is being used widely in the treatment of water supply and wastewater by forming a hard and heavy Al (OH)3* precipitate, in addition to having a smaller effect on pH.
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 .
Does coagulant polyaluminium chloride improve water quality in eutrophic shallow lakes?
The aim of this study was to evaluate the performance of the coagulant Polyaluminium chloride (PAC) in water quality improvement of six eutrophic shallow lakes in Brazilian semiarid region. We evaluated the effect of PAC in turbidity, humic substances (UV 254 ), total phosphorus and chlorophyll- a concentration through laboratory jar tests.
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.
Can polymeric PAC be used for water treatment?
Several researchers have investigated the synthesis, of PAC and its performance for water treatment. The results shows that various polymeric species of PAC yield (Al b species) are obtained and different performance efficiencies for water treatment are reported in the literature [21, 24].
What is the concentration of aluminum in Pac solution?
The aluminum concentration in the PAC solution was diluted in the ranges from 5.4 to 10.8 mg L −1. The PAC solution to Ferron solution volume ratio was 10:1, which was mixed and immediately transferred to the cuvettes in the UV–vis spectrometer for absorbance measurement.
