Spray dried poly aluminium chloride PAC for paper industry sewage treatment is mainly used as flocculant in water treatment

Spray dried poly aluminium chloride PAC for paper industry

1. AL2O3(%):26-30%2.Basicity: 80-100%1.  Brief introduction:

Spray dried poly aluminium chloride PAC 3A  is one kind of water-soluble inorganic polymer flocculant. It ls adopting advanced manufacturing technique and high quality raw material with an appearance of brown, or yellow, or white powder.

2. Application: 

Spray dried poly aluminium chloride PAC 3A  is used as the flocculating agent for the treatment of dringking water and industrial wastewater

Spray dried poly aluminium chloride PAC 3A  can be widely applied in precise casting,paper-making, printing ,dyeing, tanning and other industries.

3. Features: 

a) Spray dried poly aluminium chloride PAC 3A  is obviously effective in purifying high turbid water without adding alkaline additives.

b) Spray dried poly aluminium chloride PAC 3A is suitable for wide range of water quality,alum flower formed is quick and big, easily settled.

c) Spray dried poly aluminium chloride PAC 3A has fast flocculating rate, small corrsiveness and low labour intensity.

4. Package 

25 kg packed in plastic woven bag lined with PE bag
