Polyferric sulfate is a phosphorus remover. Manufacturers of polyferric sulfate specially have polyferric sulfate packaged with efficient phosphorus remover. Both polyferric sulfate and polyaluminium chloride can be used as phosphorus remover. Aluminum and iron neutralize phosphate in sewage to form insoluble aluminium phosphate and iron phosphate. Ferric phosphate has a smaller solubility area in water, which means that more phosphate and iron can form insoluble phosphate precipitation. Phosphate can be removed from water.
One of the main functions of polyferric sulfate is to remove phosphorus, which can be used as a dephosphorizing agent. But apart from polyiron, dephosphorizers can also be polyaluminium, calcium salts or other modified products. Customers suspect that the Dephosphorizer they purchased is Polyferric Sulfate due to its predominant content of whole iron. However, this does not mean that the dephosphorizing agent purchased by the manufacturer is polyferric sulfate, which may be an improvement of polyferric. To improve the dephosphorizing function of Polyferric sulfate, the manufacturer of polyferric sulfate should make it a better dephosphorizing agent. Or other iron salts or complex iron salt dephosphorizers mainly composed of all-iron. It can be further tested.
Phosphorus remover can be the name of a single agent or the general name of a group of agents with phosphorus removal effect. For general users, in fact, it is not necessary to be too accountable for the specific material content of the product. Mainly pursue the main performance of the product, such as whether the phosphorus remover can achieve the effect of phosphorus removal, whether other pollutants will be brought in, whether the low cost and stable standard can be reached efficiently, and what is the cost performance.
Polyferric sulfate is widely used in sewage except phosphorus and turbidity. Besides phosphorus reagents, there are also polyaluminium chloride, lime and other reagents which are modified on the basis of ferrite and aluminium salts.
