Polyaluminium Chloride
PAC-WPD is a new-type inorganic macromolecule coagulant with high efficiency, manufactured by advanced process with raw materials of good quality. It is drum dried in solid form widely used for municipal drinking treatment.
PAC-WPD is high basicity (85-92%) polyaluminum Chloride. Its high basicity and the low dosage minimize the need of pH- adjustment and small coagulant dose reduces the amount of sludge. It is pretty effectively to treat the low-temperature raw water.
Properties
The water treatment cost is 20%-40% lower than that of other inorganic coagulants.
It can lead to quick formation of flock with big size and rapid precipitation.
It has wide-range adaptability to the waters at different temperatures and a good solubility.
The dissolved liquid of PAC-WPD is slightly corrosive and suitable for the automatic dosing and convenient for operation. Furthermore, it will not block pipes over long-time usage due to its low impurity.
Polyaluminium chloride for water treatment
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
English name: Polyaluminium Chloride, abbreviated PAC
EINECS: 215-477-2
CAS NO: 1327-41-9
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
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.
Classification of poly-aluminum chloride
A, drum-type polyaluminum 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.
Packaging of polymeric aluminum chloride and points for attention
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.
How to use
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
