Wide application of polyferric sulfate
The application of Polyferric sulfate is wide. This water purification product is a light yellow amorphous powdery solid with an excellent performance of coagulation, which produces compact alum flowers with a high sedimentation rate. Polyferric sulfate is soluble easily in water. The 10% solution is red brown and transparent, with good hygroscopicity and excellent purification effect. There is no harmful substances such as aluminum, chlorine and heavy metal ions, and no water phase transfer of iron ions, non-toxic in the solution. This harmless, safe and reliable agent can help to save cost of 20% -50%. It’s widely used in the treatment of drinking water, industrial water, various industrial wastewater, urban sewage, sludge dewatering and other purification treatment.
At present, most water plants use aluminum salts as flocculants. In order to reduce the water turbidity before filtration and increase the dosage of flocculant, many water plants use excessive aluminum salt and as a result the level of aluminum in treated water increases. A new water purification agent, solution of PFAS can be got by mixing PFS and PAS with a certain percentage. Compared to other flocculants such as ferric chloride, ferric sulfate and alkali aluminum chloride, polyferric sulfate is widely used in the purification treatment of industrial wastewater , urban sewage, industrial water and drinking water because of its unique and advanced production technology, low price, wide using range of PH, low residue concentration, high sedimentation speed, good decolorization effect.
