There are many opportunities in life to change their own destiny, these opportunities for you to find, to grasp, rather than waiting for others to give you, (+ 86-15639065815) the role of cheap, large, the quality of the product and the effectiveness of use depends on their own Knowledge of the level of master, filter Xiaobian remind you that there are three main indicators to determine the quality of polyaluminum chloride: aluminum oxide content, basicity and water insolubles, of which the higher the aluminum content, the better the quality of the relative The smaller the water insoluble matter, the basic degree of salt adjustable. Under normal circumstances, we can see from the appearance, sub-brown, khaki, yellow, yellow and white, brown polyaluminium chloride are low, yellowish polyaluminium chloride are mid-range products, Yellow and white belong to high-grade products, followed by the price of Poly aluminum chloride, which, living grade water treatment aluminum oxide mass fraction of up to 30%, industrial grade water treatment aluminum oxide mass fraction up 27-29%. The measure of OH ion in polyaluminum chloride is called the basicity of the salt, and the basicity of the salt is usually defined as the percentage of the amount of OH and Al in the polyaluminum chloride. Generally, the basicity of the salt should be in the range of 40-90 % Or less.
There are a lot of advantages about PAC PACs. You must be able to say one or two of the important ones. Using PAC PACs to process the sewage is much easier than the traditional treatment methods. Good low temperature coagulation treatment efficiency and settlement efficiency, can significantly improve the solid-liquid separation efficiency, improve sedimentation filtration and sludge dewatering performance, thereby reducing the residence time of sedimentation tank and increase water production, there is an important advantage is that the polymerization Residual aluminum content in water treated with aluminum chloride (PAC) is very low, and the residual aluminum content in conventional aluminum sulfate treated water is generally 150-255 g / L, while the residual aluminum content in polyaluminum chloride treated water is only 40-55 g / L.
Not only reduce the labor intensity of workers, but more importantly reduce the user's water costs. In addition, the use of spray-dried products to ensure safet
Precipitation process will absorb a very small amount of phosphorus, but the effect is not obvious, but the effect is somewhat obvious except for heavy metals.
