New, high-quality, high-efficiency iron salt inorganic polymer flocculant, mainly used for excellent water purification effect, good water quality, no harmful substances such as aluminum, , and no water transfer of iron ions, non-toxic, non-toxic Harmful, safe and reliable, it has remarkable effects such as turbidity removal, decolorization, degreasing, dehydration, sterilization, deodorization, algae removal, and removal of COD, BOD and heavy metal ions in water. It is also used for industrial wastewater treatment, such as printing and dyeing wastewater, etc. It is also widely used in foundry, papermaking, medicine, tanning, etc.


 

  Characteristics of Polymeric Ferric Sulfate in Treatment of Oily Wastewater

Flocculation technology is widely used in the treatment of oily wastewater due to its strong adaptability, the ability to remove emulsified oil and dissolved oil, and some complex macromolecular organic compounds that are difficult to biochemically degrade. Commonly used flocculants are mainly inorganic flocculants, organic flocculants and composite flocculants.
Among the inorganic macromolecule flocculants, polyaluminum chloride, polyferric sulfate and other lower molecular weight inorganic flocculants have good treatment effect, low price, low dosage, high efficiency and are widely used.


 Industrial Wastewater Treatment
1. The treatment of printing and dyeing wastewater can replace the traditional coagulants of low molecular weight iron salts and aluminum salts. Compared with the traditional coagulants, the amount of coagulants is large, the coagulation efficiency is low, and the residues such as aluminum ions are easy to cause secondary pollution. The dosage is about 150ppm, the dosage is small, the removal rate of COD and chroma is high, and the optimal pH value condition is: 8.0.
2. Electroplating sewage treatment, can be used as coagulant and breaker. The complex is mainly copper-ammonia complex, which is stable in nature, pH=11, and is difficult to directly precipitate with alkali, polyaluminum and other coagulants. It can also be used for reuse of reclaimed water.
3. Papermaking wastewater treatment, instead of polyaluminum chloride, aluminum sulfate, etc., can be used as a coagulant, and can also be used for papermaking sludge dewatering. polymer), only polyaluminum chloride can be used.
