Description

Polyaluminium chloride PAC-031 Grade 29% 25kg Bag

CAS No: 1327-41-9
Molecular Formula: Al2Cl(OH)5

Polyaluminium chloride is a spectrum of versatile inorganic polymers  that are finding  greater use in water treatment plants  over the past 10 years. They are used as a substitute for aluminum sulphate.

The advantages of PACs arise from the following factors:

1. Lower dosage requirements – results in introduction of less material to the water
2. Shorter flocculation time than aluminum sulphate
3. Smaller amount of sludge formed
4. No requirement for neutralizing agent (soda ash, lime), because of the high basicity of PACs
5. Improved quality of treated water.

These 5 facts compensate for the higher unit price of PACs compared to conventional flocculation agents.

The discovery of PACs  has been a major game changer in water treatment facilities in most developed and developing nations.
