Polyaluminum chloride, as a common water purification agent, can be used to treat the sewage of various industries, as well as the purification of urban sewage and drinking water. But polyaluminum chloride want to achieve the ideal effect, the correct use method is essential, today for the next polyaluminum chloride in the use of dosage problem.

The use of polyaluminum chloride is determined according to different water treatment conditions. There are great differences in the treatment of industrial sewage, domestic sewage and drinking water. In particular, the dosage of polyaluminum chloride has a great influence on the effect of water treatment. Before adding polyaluminum chloride, it is necessary to add polyaluminum chloride solid into tap water to dissolve, and then continue to add tap water according to a certain proportion for dilution. Polyaluminum chloride is diluted into a certain proportion of water solution and then added.

Generally, when polyaluminium chloride is used to treat urban and domestic sewage, it needs about 30 grams per ton of sewage, and it needs to be dissolved and diluted when it is added. In the treatment of some industrial wastewater with high concentration, about 120 grams per ton of sewage is generally used, and about 10 grams is generally used in the treatment of raw water for drinking water.

The dosage of polyaluminum chloride is only a rough data. Generally speaking, the dosage of polyaluminum chloride needs to be obtained through laboratory test, so as to ensure the effect of polyaluminum chloride.

In the actual dosing, the dosage will also be changed due to other factors. For example, the ambient temperature will affect the dosage of polyaluminum chloride, the flow of sewage treatment will also change the dosage of polyaluminum chloride, and the different additives will greatly change the dosage of polyaluminum chloride, etc.
