Polyaluminium chloride has liquid and solid on the market, each with its own advantages and disadvantages. Solid polyaluminium chloride is convenient for storage and transportation, but it needs to be dissolved before use. Do not dissolve the liquid polyaluminium chloride. Add water to dilute it into a concentrated aqueous solution before use. However, at present, more solid polyaluminium chloride is used, so dissolution and dilution are essential before use. No matter how it is used, it is necessary to carry out laboratory test according to different sewage treatment to determine the correct use method and reasonable dosage in order to achieve the use effect.

The water insoluble matter of polyaluminium chloride mostly comes from production raw materials, so it needs to be controlled from the source. Traditional polyaluminium chloride is mostly produced by bauxite and industrial waste hydrochloric acid. These raw materials generally contain a large number of impurities. If the production process is not well controlled, the later polyaluminium chloride will contain a large amount of water-insoluble substances.

Polyaluminium chloride is easy to operate in use. Cost savings. Therefore, it is deeply loved by the majority of consumers. Polyaluminium chloride is not dangerous goods, but it should be noted that heat will be generated when encountering water after the outer package of polyaluminium chloride is damaged. Polyaluminium chloride is highly corrosive and strong. It will produce on human skin. A large amount of polyaluminium chloride will cause and bronchus. Taking a large amount of polyaluminum chloride by mistake will cause human oral ulceration. Polyaluminum chloride is used as a water purification agent. The secondary product is used for the purification of drinking water and urban industrial water supply. Hazards: if the use method is improper, there will be certain hazards, but as long as the operation is correct, there will be no hazards. Precautions for the use of polyaluminium chloride and the operators should be trained. Strictly follow the operating rules.

With the development of polyaluminium chloride, industrial grade polyaluminium chloride produced by spray process has begun to appear. Due to the high purity of this kind of polyaluminium chloride, it has a better effect than the drum type industrial grade polyaluminum chloride in the treatment of some industrial wastewater. However, the price of this kind of polyaluminum chloride is relatively high. Therefore, in the treatment of industrial wastewater, it is better to select the industrial grade polyaluminum chloride according to its own wastewater treatment situation, It also needs to be selected according to its own wastewater treatment process. Polyaluminium chloride can dissolve in water very quickly. Under normal conditions, polyaluminium chloride is added to water. It will dissolve rapidly and achieve the effect of complete dissolution in a short time. When the water temperature is not higher than 70 ℃, polyaluminium chloride will dissolve faster with the increase of water temperature.
