Content differentiation of polyaluminium chloride

The color of polyaluminium chloride varies with its content. For example, the appearance is powder and the color is golden yellow or light yellow and yellowish brown. With the changes of its production process and raw materials, many customers can really distinguish its content with the naked eye. Just put this product in the sun. If the content is 30, it is usually shiny golden yellow or light yellow, and the content of 28 is also shiny, but the color is a little dark yellow. If about 25 is non-standard, the color will be darker. Polyaluminium chloride does not need to add other additives. The floc has the advantages of fast and coarse formation, high activity and fast sedimentation, and has obvious purification effect on high turbidity water. It has a wide range of pH value and has no corrosive effect on pipeline equipment.

Generally speaking, the content of polyaluminium chloride within the standard range is 27-30. It is a yellow or light yellow solid powder, which is easily soluble in water and has strong bridging adsorption. How to distinguish the content of the product? In the hydrolysis process, [Al2 (OH) 3 (OH) 3] is formed through electrochemical, coagulation, adsorption, precipitation and other physicochemical changes α~, So as to achieve the purpose of purification.

In addition, the method for distinguishing the quality of different amounts of polyaluminium chloride products can also be determined by water-insoluble substances. Fill the mineral water bottle with water, take an appropriate amount of product for test, put it into the water bottle and shake it with force until it is completely dissolved. Then stand for one hour and observe the content of insoluble matter in the water at the bottom of the bottle. The lower the content of water insoluble matter, the better the product quality.
