The water in the reservoir is surface water, which contains a large amount of suspended solids, algae, bacteria and viruses, harmful ions, etc., which are harmful to the human body, so it must be treated.
Polyaluminum chloride is a water-soluble inorganic high molecular polymer between ALCL3 and AL(OH)3. The general chemical formula is [AL2(OH)NCL6-NLm] where m represents the degree of polymerization and n represents the PAC product degree of neutrality. Polyaluminum chloride abbreviated as PAC is usually also called basic aluminum chloride or coagulant, etc. The color is yellow or light yellow, dark brown, dark gray resinous solid. The product has strong bridging and adsorption properties, and during the hydrolysis process, physical and chemical processes such as coagulation, adsorption and precipitation occur.
Polyaluminum chloride is a new type of inorganic polymer water treatment flocculant. It occurs electrochemically during the hydrolysis process. It has strong bridging adsorption performance and cohesion ability. The use of polyaluminum chloride is mainly used for domestic water, industrial Water purification and industrial wastewater treatment are also widely used in papermaking, printing and dyeing, precision casting, sugar, leather, petrochemical and other industries. For example: urban water supply and drainage purification: river water, reservoir water, groundwater, industrial water supply purification, urban sewage treatment, recovery of useful substances in industrial wastewater and waste residues, promoting the sedimentation of pulverized coal in coal washing wastewater, starch recovery in starch manufacturing, Various industrial wastewater treatment: printing and dyeing wastewater, leather wastewater, fluorine-containing wastewater, heavy metal wastewater, oil-containing wastewater, papermaking wastewater, coal washing wastewater, mining wastewater, brewing wastewater, metallurgical wastewater, meat processing wastewater, sewage treatment, paper sizing, sugar Liquid refining, casting molding, cloth anti-wrinkle, catalyst carrier.
Instructions:
1. Mix the solid product with room temperature water at 1:2.5-1:3 (weight ratio) and stir for about 30 minutes. After it is completely dissolved, add 30-40 times of water to dilute it or dilute it into a liquid according to the required concentration (source The greater the water turbidity, the more water is added for the second dilution).
2. When the source water turbidity is 100-500mg/L, the dosage is 5-10mg, that is, the dosage per thousand ton of water is 5-10Kg. Before use, it is best to conduct a small test according to the water quality characteristics, select the best value, and then put it into use.
3. The product packaging is lined with plastic bags and the outer layer is plastic peritoneal woven bags, each bag weighing 25 kg.
4. Store in a cool, dry place to prevent sun and rain.
