EspañolProduct overview
Properties: Poly aluminum chloride is a kind of inorganic material, a new water purification material, inorganic polymer coagulant, referred to as poly aluminum.
It is a water-soluble inorganic polymer between AlCl3 and Al(OH)3.
The general chemical formula is [Al2(OH) NCL6-N] M, where M represents the degree of polymerization and N represents the neutral degree of PAC product.
Applications
In the sewage treatment industry, polyaluminum chloride is widely used in the sewage treatment, which can make the fine suspended matter in the sewage coagulate and precipitate quickly, so as to achieve the purpose of purifying the sewage. The use of polyaluminum chloride can make the sewage treatment faster, reduce the difficulty of treatment, but also reduce the content of nitrogen, hydroxide and other harmful substances in the sewage, so as to achieve higher environmental benefits.
In the paper industry, polyaluminum chloride can be.
