Polymeric ferric sulfate solid(SPFS)

DATE:2017-10-19 / READ:

Polymeric ferric sulfate is a kind of inorganic polymer coagulant with excellent performance. The morphological character is light yellow amorphous powder solid. It is easy to dissolve in water, and 10% (mass) water solution is red brown transparent solution, hygroscopicity. Polyferric sulfate is widely used in drinking water, industrial water, various industrial wastewater, urban sewage, sludge dewatering and other purification treatment.
CAS No. : 1327-41-9
Molecular formula: [Fe2 (OH) n (SO4) 3-n/2]m (where n<2, m=f (n))
Appearance: yellow or reddish brown amorphous powder or granular solid.
Performance characteristics:
1,New type, high quality and high efficiency iron salt inorganic polymer flocculant;
2,Excellent coagulation performance, alum dense, sedimentation speed is fast;
3,Water purification effect is good, good water quality, no aluminum, chlorine and heavy metal ions and other harmful substances, there is no iron ion aqueous phase transfer, non-toxic, harmless, safe and reliable;
4 removal of turbidity, decolorization, deoiling, dehydration, sterilization, deodorization, algae removal, removal of COD, BOD and heavy metal ions in water and other significant effect;
5 the pH range of water body is 4-11, the best pH range is 6-9. After purification, the pH value of the raw water and the total alkalinity changes little, and the corrosion of the equipment is small;
6, the purification effect of micro polluted, algae containing, low temperature and low turbidity raw water is remarkable, and the purification effect of high turbidity raw water is better;
7, less dosage, low cost, processing costs can save 20%-50%.

Application of polymeric ferric sulfate:
Polyferric sulfate in rare earth industrial wastewater treatment: for example, when the device on the surface of small solid particles in wastewater of high concentration and ionic membrane and always maintain a certain distance, greatly reduce the harmful substances and the membrane surface on the membrane surface have the opportunity to avoid pollution, polyferric sulfate to improve water circulation over; this process will not only with the concentration of chloride the separation process of rare earth ammonium extraction wastewater of high concentration wastewater, recycling of rare earth industry standards, and through the electrolysis process and solar energy for a successful recovery of hydrochloric acid and ammonia reactor, polyferric sulfate reducing rare earth industry production of raw materials recycling, but also through the use of fuel cell will be added a lot of energy recovery, treatment the waste water for the cost of 40 yuan, 1600 tons / day, including ammonium chloride 100g/L calculation, through this process, hydrochloric acid and ammonia generation of water can achieve profit 110 thousand This reduction, yuan, not only to the country's sewage treatment and disposal of stable and harmless targets; strict control of rare earth heavy metals in industrial waste water and toxic and harmful substances polyferric sulfate content; in the premise of safety, environmental protection and economic recovery, waste gas, wastewater using polymerization iron sulfate and energy resources, to achieve wastewater and the comprehensive utilization of waste management, energy conservation, development of circular economy to achieve.
Industrial wastewater treatment
1, the printing and dyeing wastewater treatment, to replace the traditional low molecular ferric and aluminum salt coagulant, dosage of coagulant, compared with the traditional coagulation efficiency is low, aluminum ions caused by the residual characteristics of two pollution, polyferric sulfate dosage of about 150ppm, the small amount of COD and the degree of color the removal rate is high, the best pH value is: 8. [2]
2. Electroplating wastewater treatment can be used as coagulant and complexing agent. The complex is mainly copper ammonia complex, its properties are stable, pH=11, it is difficult to precipitate directly with alkali, poly aluminum and other coagulants. It can also be used as reclaimed water.
3, wastewater treatment, substitution of poly aluminum chloride, aluminum sulfate, used as coagulant, can also be used as papermaking sludge dewatering in papermaking wastewater treatment can not use polyferric sulfate white water recovery process (including cationic polymer), polyaluminium chloride with only.
Packing methods: 25kg, 50kg, plastic woven bags lined with polyethylene bags
Storage notes: store in a cool, dry and well ventilated warehouse. Keep away from fire and heat. The relative humidity remains below 75%. Packing must be sealed, never damp. Should be stored with easy (combustible) substances, alkalis, alcohols, etc., should not be mixed storage. Should not be stored for a long time, so as not to degenerate. The storage area should be equipped with suitable materials for leakage.
