Poly Aluminium Chloride (PAC)

Poly Aluminium Chloride (PAC)

Innovative Water PAC is used for the treatment of wastewater and industrial effluent, drinking water, swimming pool water, the treatment of sewage and industrial effluents. Poly Aluminium Chloride (PAC), is a water-soluble inorganic polymer between AlCI3 and Al(OH)3, its general formula is [Al2(OH)nCl6-nLm], of which m represents the degree of polymerization and n represents the degree of neutrality of PAC products. Poly-aluminium chloride (PAC) based coagulant.  It is also used extensively in the pulp and paper processing industry. This product has strong bridge adsorption performance. During the hydrolysis process, condensation, adsorption, precipitation as well as other physical and chemical processes also occurs at the same time. The fundamental difference between poly aluminium chloride and traditional inorganic coagulants is that the traditional inorganic coagulants is low molecular crystal salt, but the structure of poly aluminium chloride is composed of polycarboxyl complex with variable morphology, it has high speed of flocculating and precipitating, suitable for wide PH range, no corrosive to pipeline equipment, obvious water purification effect, it can effectively remove chromaticness, Suspended Solids(SS), Chemical Oxygen Demand(COD), Biochemical Oxygen Demand(BOD) and such heavy metal ions as arsenic and mercury in the water. This product is widely used in drinking water, industrial water and wastewater treatment field.

Poly Aluminium Chloride Product Application

Poly Aluminium Chloride is a kind of inorganic polymer, which is made from the reaction of aluminum mineral powder and hydrochloric acid. As one of coagulants it is an ideal and economical water purifier at present. This product is widely used for purification and treatment of domestic drinking water, industrial water, domestic sewage and industrial wastewater; and the purified water completely meets the national standard of domestic drinking water. This product is less corrosive to the equipment in the purifying device, which can simplify the purifying equipment and reduce the area of the purifying equipment, thus saving investment and realizing high-speed purifying. The product can sterilize and deodorize, remove fluorine, aluminum and chromium, remove oil, turbidity and heavy metallic salt, remove radioactive contamination as well. It is widely used for purifying various water sources.
Purify drinking water and domestic sewage.

Purify industrial water, industrial waste water, mine and oilfield injection water; purify various chemical waste water from paper making, metallurgy, coal washing, leather working, etc.

Industrial application; paper sizing, printing and dyeing, bleaching and dyeing, cement accelerator, precision casting hardening agent, refractory materials adhesive, glycerin refined, sugar liquor refined, cloth anti-wrinkle, medicine, cosmetics and other industries, the waste water can be recycled.

It is used to separate oil and water in refinery industry and has perfect effect.

Poly Aluminium Chloride Usage

Mix Poly Aluminium Chloride (solid) with normal temperature water at the weight ratio of 1:1.3 to 2.5 for 30 minutes. After dissolving this product, dilute it with 30-40 times more water or dilute it according to the required concentration to use.

Small experiment should be undertaken according to water quality condition when this product is concretely used, then choose the optimal usage.
