Polyaluminium Chloride Crystal

Poly aluminum chloride is an inorganic polymer flocculant made from aluminum hydroxide powder by a series of processes ,abbreviation PAC, and it is a multi-hydroxyl, multi-nuclear complex cationic inorganic polymer flocculant, solid appearance is white and yellow powder, easily soluble in water, has strong bridging adsorption, along with electrochemical, coagulation, adsorption and precipitation physical changes in the process of hydrolysis, and finally generation [AL₂(OH)₃(OH)₃], so as to achieve the purpose of purification.

Application

Widely used in municipal sewage treatment and sludge treatment, industrial wastewater, petroleum, printworks, cosmetics, medicine, papermaking and other industries, and can also be used in cement accelerator and casting molding agent.

Parameters

Instructions

Preparation: Generally, it is prepared into the solution of 5%-10%, and it should be stirred evenly after adding water;

Dosage: The dosage varies depending on the treated water, and it is determined by the turbidity of the wastewater, which can be determined by experiments.

Condition of use: The applicable pH range of water is 4-14, but the optimum pH range is 7-9.

Packing, Storage and Notes:

1. Woven bag with moisture-proof lining.

2. PAC effective storage period: one year for solid and half a year for liquid.

3. Avoid to be damp, but the effect will not be affected if getting damp.

4. Do not store with other chemicals, and PAC from different manufacturers should not be mixed.

5. Some sewage treatment can be used with PAC and PAM, but do not mix, and generally use PAC in advance, and then PAM.
