Ferric sulphate
1. Brief Introduction
Based on the market demand, our company developed ferric sulfate(Fe2(SO4)3) with the advanced process technique. The product include solid and liquid. Liquid appears brown, and solid is yellow powder. We are the biggest manufacturer of ferric sulfate in China, and our ferric sulfate ISO9001-2000 certified,and NSF certified (2006-2008).
Please refer to the national standard of <water purifying agent--polyferric sulfate, PRC.

2. Uses
Ferric sulfate is a high-efficiency inorganic flocculant, mainly used to purify and treat all kinds of drinking water, industrial water, wastewater and sewage. Moreover, it can be used as catalyst, mainly used in the liquefaction and vaporization.
3. Features
(1) has the same features as inorganic flocculants such as polyaluminum chloride, etc.
(2) low use level and cheap cost;
(3) has stronger effect to remove COD at the slightly acid condition;
(4) specially effective to treat the wastewater from oil field and oil extraction,coking wastewater.
4.Usage and cautions
before use, you should test it in beaker to determine the dosage
1, dissolved in pond in 20-50% concentration, stirred it, then standing to till the water is brown red2, according the original medicine, its dosage is equal to polyaluminum chloride, is 1/3~1/4 of solid aluminum sulfate. The solution follows the concentration3, during use, feeding the medicine by measure tank 4, watch the deposit forming state
condense phase : In short time, it form small deposit in water, the water is more cloud, the test rev in beaker is 250-300r/min in 10-30s, the time ashoule be less tham 2 min
flocculation phase: The deposi become biger nad biger, it need nor flow seppd and time(10-15min), you can see lots of deposit, there are clear interface in waterstir: first: 150r/min in 6min, then 60r/min in 4minsubside phase, The deposit is settled in water, you can use slanting tube or board( best methos is air float way), big deposite will fall into bottom, the smaal will become big, it last stage, the residual cloud will be changeless. Time: 20-30r/min in 5min, standing in 10min.
5, intensive filtration :it can increase the purified efficiency by filter structure and aids.
6, To industry sewage, the uses is similar with water making factory. To such water with high color, COD and high BOD, you can use some aids.
7, The former chemical settling equipment, you just need adding a dissolved pond.
8, Stored in dry place, avoid moisture and heat(<80 ), no break the packing, this product can be preserved in long time.
9, This product should be dissolved before use, the dissolved equipment and feeding equipment should be made from anticorrosive material.
5. Pachage
25Kg p/p bags or 800kg p/p bags.
6. Transportaion
Owning specially-used railway,company can provide container and train wagon transportation for customers. Being well cooperative with local motor carriers and many shipping companies,company can consign products with automobiles conveniently.and can freight products to all harbors around the world.
