YD-0301 Food grade Liquid poly ferric sulfate

Application:

YD-03 food grade poly ferric sulfate, there are two kinds of liquid and solid, is mainly used in drinking water treatment. In the use of high-quality raw materials at the same time, the unique methods to removal heavy metals, heavy metal content in the product is only 50% of content of the national standard, at the same time zero chloride ion and nitrite residue. According to PH requirements for the drinking water after treatment, through strict control of the production process, improve the degree of polymerization of OH radical with Fe3+, the flocculation ability of products has been further improved, is the best high efficient inorganic flocculant to replace Aluminium salt to reduce aluminum ions remaining in water treatment.Using our product in drinking water treatment, can make the water physical and chemical index comply with the hygiene requirements.
