What are the uses of polyaluminum chloride?

The color is yellow or light yellow, dark brown, dark gray resin-like solid. The polyaluminum chloride produced by Lvjie has strong bridging and adsorption performance. During the hydrolysis process, physical and chemical processes such as condensation, adsorption and precipitation occur. The fundamental difference between polyaluminum chloride and traditional inorganic coagulants is that traditional inorganic coagulants are low-molecular crystalline salts, while the structure of polyaluminum chloride is composed of multiple carboxyl complexes with variable morphology, which has a fast flocculation and precipitation speed, and is suitable for The PH value range is wide, non-corrosive to pipeline equipment, and the water purification effect is obvious.

Polyaluminum chloride use

⒈ Purification of urban water supply and drainage: river water, reservoir water, and groundwater.

⒉ Industrial water supply purification.

3. Urban sewage treatment.

⒋The recovery of useful substances in industrial wastewater and waste residues, the promotion of the sedimentation of pulverized coal in the coal washing wastewater, and the recovery of starch in the starch manufacturing industry.

⒌Various industrial wastewater treatment: printing and dyeing wastewater, leather wastewater, fluorine wastewater, heavy metal wastewater, oily wastewater, papermaking wastewater, coal washing wastewater, mine wastewater, brewing wastewater, metallurgical wastewater, meat processing wastewater, sewage treatment.

⒍Sizing for paper making.

7. Cast molding.

8. Medical refining

9. Cement quick-setting.

10. Cosmetic raw materials.

Precautions for the use of polyaluminum chloride

⒈Should carry out a small test according to the water quality first, and select the best point with good water purification effect and small amount of input. The solution should be used with the preparation, and the amount of non-drinking water should be selected according to the actual situation.

⒉When using a solid, first add water to dissolve it to form a 10-25% solution, then dilute with water to the required concentration, add water to slowly feed the material when dissolving, and continue stirring.

⒊ Water treatment chemicals of different manufacturers or different brands cannot be mixed, and must not be mixed with other chemicals.

⒋ The original liquid and diluent are slightly corrosive, but lower than other inorganic flocculants.

⒌ Product effective storage period: half a year for liquids and two years for solids. The solid product can still be used after damp.

 6. This product is properly added, and the purified water quality meets the sanitary standards of drinking water.
