Electroplating wastewater treatment: application of polymeric ferric sulfate

Groundwater, as one of the important freshwater resources on Earth, directly affects human life and production activities in terms of water quality.

Printing and dyeing wastewater mainly comes from the production process of printing and dyeing plants. In the process of printing and dyeing, a large number of dyes, auxiliaries and high concentration salts and other chemicals need to be used. These chemicals will be dissolved in water during the production process to form wastewater. In addition, the printing and dyeing process will also produce a large number of textile waste and solid waste, which will also become an important part of wastewater after treatment.

Production of papermaking wastewater

Polyferric sulfate (PFS), as an efficient inorganic polymer coagulant, has a wide range of applications in the field of water treatment. The types of wastewater it can treat mainly include but are not limited to the following:

Generation of mine wastewater
Mine wastewater refers to the general term for the wastewater discharged after mining, mineral processing, tailings dam, and slag disposal sites. The main sources include:

If heavy metal wastewater is not properly treated and discharged, it will seriously pollute water bodies, affect water quality safety, cause long-term damage to the ecological environment, and accumulate harm to human health through the food chain, causing various diseases.

Fluorination wastewater is mainly generated from processes that use fluorine-containing substances in industrial production, and the specific sources include:
Aluminum industry: In the process of electrolytic aluminum production, the use of fluoride salts as co solvents will generate a large amount of fluorine-containing wastewater.

The following is a detailed introduction to the causes and characteristics of leather wastewater, as well as the principles and advantages of using polyaluminium chloride to treat leather wastewater:
