Is Pac better than aluminium sulfate flocculant?

Comparing to aluminium sulfate flocculant, the quality of water treated with PAC is better; the total cost reduced by 15%~30%, and the solubility is better. It can be applied to water with broad pH range. The floc function valid in water of pH 5 to pH 9

How does polyaluminium chloride coagulation work?

The use of polyaluminium chloride (PAC) for continuous coagulation in swimming pool systems is highly recommended, particularly due to the threat posed by Cryptosporidium. PAC works by extracting and aggregating dissolved, colloidal, and suspended matter, forming flocs that can be efficiently trapped by filters.

What are the advantages of using PAC as flocculant?

CAS No.: 1327-41-9 Using PAC as flocculant, the speed of flocs forming and settling is quick. Flocs formed is easy to filter Comparing to aluminium sulfate flocculant, the quality of water treated with PAC is better; the total cost reduced by 15%~30%, and the solubility is better.

How is polyaluminium chloride dosed?

However, when dosed with polyaluminium chloride, removal rates improved dramatically to over 90%. Dosing Rate and Method: PAC should be continuously dosed directly from the containers it is delivered in at a rate of approximately 0.1ml/m3 of the circulation flow. It is crucial not to dilute PAC with water as it will form a gel.

What is polyaluminium chloride used for?

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. CAS No.: 1327-41-9

What is the PAC dosing rate for a pool?

This can typically be achieved within the space above the filter media. Dosing Calculation: For pools with a capacity of 450m3 (100,000 gallons) and a turnover period of 2 hours, the circulation rate is 225m3 per hour. Therefore, the PAC dosing rate for this pool would be 22.5ml per hour.
