Polyaluminium chloride is also called polyaluminium chloride as a kind of water purification material, inorganic polymer coagulant, also known as polyaluminium.
Due to the polymerization of hydroxide ions and polyvalent anions, the molecular weight of high inorganic polymer water treatment agents.
The shape can be divided into solids and liquids.
Solid colors are brown, beige, golden and white, and the liquid can be colorless and transparent, pale yellow, pale yellow to yellow brown.
The advantages of polyaluminium chloride, polyaluminium chloride has a good stability by spray drying, with high moisture content, hydrolytic speed, adsorption ability, form large alum, concentrated precipitation, low turbidity water, dewatering performance is good wait for an advantage.
Under the same water quality, especially the spray drying of polyaluminium chloride dosage reduction under the condition of the water quality is poor, compared with the drying of polyaluminium chloride, spray drying product quantity reduced by half, this not only reduces the labor intensity of workers, lowering the cost of water treatment.
Industrial water purification;
Urban sewage treatment;
In the recycling of useful substances, industrial waste water and waste residue can promote the coal washing wastewater in the subsidence coal, and the starch in starch production.
Printing and dyeing wastewater, leather wastewater, fluoride wastewater, heavy metal wastewater, oil wastewater, papermaking wastewater, coal washing wastewater, mine wastewater, brewing wastewater, metallurgical wastewater, meat processing wastewater.
Methods for the use of polyaluminium chloride:
1. According to the proportion of water quality, the average water purification dosage is about: 5-100g/ton of liquid product, 20 ~ 25kg/ton (according to the commodity), which can be determined by beaker test;
2. The preparation can be directly added to the water. The amount of water can be determined by the dosage and dosage, and the water should be evenly mixed after adding water.
