Sometimes, when we buy polyaluminum chloride, we always feel that we can't get the desired result, so we often try again. You should know that when you use a lot of products, there are always a lot of things to pay attention to! But why is polyaluminium chloride not achieving the desired result?
Polyaluminum chloride is an inorganic polymer coagulant. Mainly through the compression of the double layer, adsorption neutralization, adsorption bridge, sediment network capture and other mechanisms, so that the fine suspended particles and colloidal ions in the water destabilization, aggregation, flocculation, coagulation, precipitation, to achieve purification treatment.
The active ingredient of polyaluminum chloride is ALCl3, and the content of active ingredients is also greater than 27%, more than 29%. The hydrolysis of aluminum trichloride is actually the ionization of aluminum ion hydrolysis. Because aluminum is an amphoteric hydroxide, double hydrolysis occurs. When the concentration of PAC in the solution is less than 3%, the effective content is less, and the ionization rate of aluminum trichloride is large, resulting in a failure to produce a coagulation mechanism, but if you increase the concentration of the solution, the ionization rate is reduced. The coagulation mechanism can occur, that is, the principle of ionization balance, so it is best to carry out a small sample test before use. At the time of use, the product (solid) and normal temperature water were added while stirring at a weight ratio of 1:3, and after complete dissolution, water was added to dilute to the desired concentration. When the specific addition is made, a small test should be carried out according to the water quality, and the best dosage should be selected and then used. If the effect is still not so obvious, then Huaquan suggests that you can use PAM together, but when the two are used at the same time, the two dosing devices should be separated, otherwise the two will react to form a latex and lose coagulation. The worst thing is to block the dosing system and destroy the system. It is best to add PAC first, then add PAM, the effect is good.
After more than 30 years of development, Henan Huaquan is committed to the production and research of water treatment materials! Up to now, overseas branches have been established and sold to more than 30 countries! We are extremely strict with all kinds of water treatment materials! In order to ensure the satisfaction of our customers! Because we always adhere to the principle that "Your satisfaction is our hope, your hope is our pursuit"!
