What is poly aluminum chloride?
Polyaluminium Chloride is an acidic solution. Classified as corrosive at higher concentrations, it is typically yellow in colour. It is miscible with water at all concentrations although dilute solutions hydrolyse to precipitate Aluminium Hydroxide (Al(OH)3).
How do you make poly Aluminium chloride?
The polyaluminium chloride preparation method comprises the following steps: firing bauxite for 0.5-2 hours under the temperature of 1200-1500 DEG C, and crushing; 2)adding bauxite powder and calcium aluminate powder in a reaction kettle, adding 25-30% of hydrochloric acid solution in the reaction kettle, heating to …
Why is poly Aluminium chloride?
Polyaluminium chloride(aluminium chlorohydrate) also simply called PAC, is used in deodorants and as a coagulant in water purification. This compound is preferred in some cases because of its high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminium salts.
How do you dilute PAC powder?
Take 10 ml of this solution into 500 ml Conical flask and dilute to 200 ml with distilled water. Add 25 drops of Conc. H2SO4 and mix well. Pipette 25 ML of 0.025 M EDTA Solution into the prepared sample solution and swirl well.
How do you use PAC powder for water treatment?
PAC is directly and continuously dosed from the containers in which it is delivered at a rate of about 0.1ml/m3 of the circulation flow. (It is very important that it is not diluted with water as it will form a gel.) This must be mixed as evenly as possible throughout the water flow.
Why is PAC used in water treatment?
Polyaluminum Chloride (PAC) is one of the most efficient water treatment chemicals utilized today. It is widely used in both potable water and wastewater treatment because it provides high coagulation efficiency and it has the widest pH and temperature application ranges compared to other water treatment chemicals.
