Brief introduction of Polyaluminium Chloride

Poly-aluminium chloride is an inorganic polymer coagulant, because of the hydroxyl ion bridging and polyvalent anion polymerization production of larger molecular weight, high charge of inorganic polymer water treatment chemicals.

Poly-aluminium basic informationm chloride

Chinese name: poly-aluminium chloride (referred to as poly-aluminum)

Chinese alias: basic aluminum chloride;Aluminium chloride; Hydroxy-aluminum chloride;  PAC

Poly aluminium chloride  CAS NO:1327-41-9;

English name: Polyaluminium Chloride, abbreviated PAC

EINECS:215-477-2

Molecular formula: Al2Cl (OH) 5

Technical standards: national standards for product quality in line with GB15892-2009

Appearance: white, golden yellow, tawny, reddish brown granule/Flake

Product form: powdery solid liquid

Physical propertiesresin-like solid: colorless or yellow .

Its solution is colorless or yellow transparent liquid, sometimes dark gray mucus due to containing impurities.

Poly aluminium chloride

Poly (a) its flocculation performance of aluminum chloride is as follows:

A, role of colloid substances in strong electric and water.

B, hydrolysis products on water adsorption of suspended matter in high bridge.

C, on the selective adssubstances.orption of dissolved

PAC use precautions, and dosage

1, according to the different raw water conditions, can do small trial first before seeking the best dose. For ease of calculation, configuration test solution by weight (w/w), with 2~5% distribution as well.. With 3% solution: solid 3G of poly aluminum chloride, wash 200ml sung in the graduated cylinder, jiaqingshuiyue 50ml, dissolution and dilute with water to 100ml scale again, shake the can.

2, poly aluminum chloride for the production of solid: 1:15 clear water =1:9 to weight ratio (liquid product is 1:2 per cent) mix dissolve. Hydrolysis of aluminum oxide content of less than 1% solution, will reduce effectiveness of high concentration is too easy addition of uniform.

3, dosing scale seeking the best dosing the amount of dosing, and look at adjusting in the running.  See fewer sedimentation tanks alum, and dark, the dosing volume is too small; As seen on sedimentation alum and, cloud high, the dose should be adjusted.

 

Properties of polyaluminum chloride

A, purified water is better than aluminum sulfate flocculant, compared to the cost of water and low 15-30%.

B, sedimentation of flocs formed quickly, fast, processing power than traditional products such as aluminum sulfate.

C,Alkalinity in water less than c, consumption of various inorganic flocculant, and without injecting or injecting little alkaline agents.

D PH5.0-9.0 range can be condensed, adaptation of the source water.

E, corrosive small, good operating conditions.

F, solubility is better than aluminum sulfate.

G, salt added to water less, conducive to the ion exchange process and high purity water.

H, to source water adaptability of temperature better than inorganic flocculant of aluminum sulfate.

 

Classification of poly-aluminum chloride

Pattern classification

A, liquid form of poly-aluminium chloride is not drying, without dilution, loading and unloading easy to use, the price advantage of relatively cheap, disadvantage is the transport required Poly-aluminium chloride tank cars, unit transport costs and increasing (solid equivalent of 2-3 tons per ton of liquid)

 

After drying form b, solid polymeric aluminum chloride, has convenient transportation advantage, does not require tank cars, disadvantage is that also need to be diluted when used, increase the intensity of work.

 

Technology category

A, drum-type poly () aluminum chloride content in General, water insoluble high, usually used in wastewater treatment.

B, plate-and-frame type poly () high aluminum chloride content, insoluble matter in water, wastewater treatment and drinking.

C, spray drying poly () high aluminum chloride content, water-insoluble, dissolve faster. And higher standards for drinking water treatment.

 

Use

A, urban water supply and drainage cleaning: water, groundwater, river water, reservoir.

B, industrial water purification.

C, urban wastewater treatment.

D, useful substances in industrial waste water and solid waste recycling, promoting the settlement of pulverized coal in coal washing waste water recovery of starch, starch manufacture.

E, industrial wastewater treatment: wastewater from printing and dyeing, leather, heavy metal waste water, waste water, fluoride-containing wastewater, coal washing waste water containing oil wastewater treatment, paper making, metallurgy, mine wastewater, wastewater from the brewing wastewater effluent,

f meat processing wastewater and sewage treatment.

 

Packaging of polymeric aluminum chloride and points for attention

PAC packaging:

1, plastic bags, plastic film set in, each bag of net weights 25kg, also can be modified according to user requirements, while liquid polyaluminium chloride sales.

2, this product is the prohibition of poisonous substances mixed loading, transportation and storage, the product should be kept in indoor drying, ventilation, shade, and do not damp.

 

Poly-aluminum chloride

1, use should be made according to the quality scale, elect water purification effect is good, put a small amount of the best points. Solution should be mixed with used, amount of non-drinking water should be selected according to the actual situation.

2, when using solid, and water dissolved with the distribution of 10-25% solution and diluted to the required concentration of water, slowly feeding first when dissolved in water, and stir it constantly.

3 different brands of water treatment chemicals, different manufacturers or cannot be mixed, and shall not be mixed with other chemicals to save.

4, ML and diluent slightly corrosive, but lower than other inorganic flocculants.

5, effective storage products: liquid for half a year, two years solid.

Solid product after the tide can still be used.

6, this product has been a reasonable addition, purify the water quality after compliance with drinking water standards
