The precipitate of polyferric sulfate (PFS) after using

Polyferric sulfate (PFS) is widely used in recent years as a flocculant, has been recognized by our customers, it is in water treatment and iron flocculation effect irreplaceable. Our company produces PFS since put into production output reached 6,000 tons, the products are sold to major electric power, iron and steel, metallurgy industries. Due to good quality, fast flocculation, in addition to iron obvious and received high praise from customers.

Under normal circumstances, there is no precipitate PFS, if the sediment, it should be polymerized iron manufacturers produce the acid and ferrous sulfate too many impurities inside the main impurities acid and ferrous sulfate which is a titanium white powder, titanium dioxide as a byproduct of ferrous sulfate is mainly because manufacturers of titanium dioxide, ferrous sulfate, acid inside the titanium dioxide separation caused by incomplete. Sewage treatment already, but due to transport, storage trouble, so to be dried into a solid polymer, but now there are customers or fluid requirements, in fact, just for convenience in the course of dosing. Really no need to buy a dosing device requires only 3,000 yuan, so that you can put into a liquid solid ferric sulfate diluted, and is automatic dosing, saving time and effort. Solid ferric easy transportation, storage is simple and can greatly reduce the cost to the customer.

The process of producing polyferric sulfate, ferrous sulfate, sulfuric acid as raw materials. Ferrous sulfate and sulfuric acid molar ratio of 1:0.32-0.613. Nitric acid as the oxidant. Ferrous sulfate and nitric acid molar ratio of 1:0.33-0.5. Stirring at atmospheric pressure under conditions of slow generation liquid iron, and finally into the reactor at 50 ° -100 ℃ polymerization reaction. PFS spray form. The process for short reaction time, short production cycle, improve production efficiency. Pure and stable product quality, versatility, oxidizing nitric acid can be recycled, the use of raw materials and the heat of reaction heat of dissolution, low energy consumption, low cost, easy operation, no pollution of the atmospheric environment.

Source Water filtration to provide you with polyferric sulfate solid product manufacturing methods: the use of liquid iron as raw material, winning the air as the oxidant, after a low temperature dehydration, crushing, high temperature oxidation, cooling telomerization, curing, aging, crushed to the finished product.
