Polyferric sulfate is a kind of inorganic polymer coagulant, which is mostly used for purification of drinking water, industrial water, industrial wastewater and urban sewage. It is generally a light yellow solid, easily soluble in water, and the water solution is a reddish brown transparent liquid. The molecular formula of ferric sulfate is Fe2 (SO4) 3, a light yellow particle. The water solution is a reddish brown viscous liquid, sensitive to light, easy to absorb moisture, and slowly dissolves in water.
Polymerized ferric sulfate is polymerized by ferrous sulfate through oxygen and nitric acid to produce liquid polymerized ferric sulfate, which forms solid polymerized ferric sulfate after drying. Polyferric sulfate is a kind of high polymer flocculant with high efficiency and high quality. It has good coagulation effect, dense alum flower, fast settling speed, excellent water quality after purification, and no harmful substances such as aluminum, chlorine and heavy metal ions. It has remarkable effects in turbidity removal, decolorization, deodorization, dehydration and deodorization, small dosage, low corrosion to equipment and wide pH range of water, It has corresponding national standards.
Ferric sulfate is prepared by adding sulfuric acid to ferric hydroxide, or by the reaction of rust and dilute sulfuric acid. It is commonly used in silver analysis, sugar determination, as fuel, ink, disinfection, catalysis, etc., and can be used as fertilizer and weed insecticide in agriculture.
The essential difference between PFS and FeSO4 results in a huge difference in their use. The price of a ton of PFS is about 1500 yuan, while that of FeSO4 is about 400 yuan. The two kinds of goods must not be confused.
The general treatment of acidic sewage will add basic polyaluminum chloride, but this is not environmentally friendly, sewage treatment are now ordinary PAC, Ha
Can be used, but this process will certainly not be achieved alone. Now conventional with other pharmaceutical processes, can be completely up to standard. Lear
Chongqing Huadong Chemical have bought me a few times before the quality can be bought you can ask, this guy's price is lower than others, 183 @ 2302-6967
High-purity white more expensive, more about 17,000 anions more normal. Polyaluminium chloride PAC mainly depends on your use of occasions, the price of drinkin
