1, poly (co) aluminum chloride mechanism of action
Poly (aluminum chloride) is an inorganic polymer coagulant, due to the bridging effect of hydroxyl ions and polyvalent anion polymerization produced a larger molecular weight, higher charge of inorganic polymer water treatment agent . The formula is as follows: [AL2 (OH) nCL6-n] (n is 1-5.m≤10) Salt degree: B = n / 6 × 100%, its coagulation function is as follows:
A, colloidal substances in the water strong neutralization effect.
B, hydrolysis products of suspended solids in the water excellent bridge adsorption.
C, the selective adsorption of soluble substances.
The main form of poly (aluminum) chloride in water is AL13O4 (OH) 247+
2, poly (aluminum chloride) performance
A, purified water quality is better than aluminum sulfate coagulant, the cost of water compared with 15-30% lower. B, flocculation formation fast, settling speed, than aluminum sulfate and other traditional products processing capacity. C, the consumption of water alkalinity is lower than a variety of inorganic coagulant, which can not vote or less alkaline agent. D, to adapt to the source of water PH5.0-9.0 range can be condensed. E, corrosive small, good operating conditions. F, solubility is better than aluminum sulfate. G, the treatment of salt in the water increase is less conducive to ion exchange treatment and high purity water. H, the adaptability of the source water temperature is better than aluminum sulfate and other inorganic coagulants.
3, poly (a) the use of aluminum chloride
A, urban water supply and drainage purification: river water, reservoir water, groundwater b, industrial water purification c, urban sewage treatment d, industrial waste water and waste recycling of useful substances, promote coal washing wastewater coal precipitation, starch manufacturing starch Waste water, waste water for papermaking, coal washing wastewater, mine wastewater, brewery wastewater, metallurgical wastewater, meat processing wastewater f, sewage treatment g (waste water), waste water, waste water, , Paper sizing h, sugar refining i, casting molding j, cloth wrinkle k, catalyst carrier l, pharmaceutical refining m, cement quick-setting n, cosmetics raw materials.
Instructions:
1, depending on the amount of water treatment is different, the general water purification dosage is about: liquid products 5-100 g / t, solid 2-30 g / ton (commodity), can be determined by beaker test.
2, the preparation can be directly added to the water, add water can be determined by the amount of dosage and treatment of water, add water should be stirred evenly.
Precautions:
1, different manufacturers or different brands of water treatment chemicals can not be mixed, and shall not be mixed with other chemicals.
2, the original liquid and dilute slightly corrosive, but lower than the other kinds of inorganic coagulants.
3, the effective storage period: liquid half a year, solid one year. Solid products can still be used after the tide.
4, the product by a reasonable vote, after purification of drinking water quality in line with health standards.
