Home > Poly Ferric Sulfate Production
We are a large-scale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment, milling equipment, mineral processing equipment and building materials equipment. And they are mainly used to crush coarse minerals like gold and copper ore, metals like steel and iron, glass, coal, asphalt, gravel, concrete, etc. With more than 2,500 case sites, the scientific management method, the refined manufacturing process, and the innovative manufacturing concept,have rapidly grown into the mining machinery production and export bases in China even the world.
Poly ferric sulfate pfs is a kind of polymeric coagulants widely used in china in the past 20 years and reveals certain advantages in advanced treatment of wastewater.In this paper, three samples were synthesized by different methods sodium nitrite catalytic oxidation method pfs-1, one-step method pfs-2 and nitric acid oxidation method pfs-3.
Continue readingThe aim of this work was to produce a ferric sulphate rich solution from acidic coal mine drainage that could be used as coagulant.Precipitating the iron at ph 3.8, followed by dissolution in sulphuric acid, produced a coagulant consisting of 12.4 iron and 1.3 aluminium.Water treatment tests proved that this coagulant was as efficient as the coagulant chemicals conventionally used in water.
