The Changes of Polyferric Sulfate in Wastewater

Polyferric sulfate undergoes a series of changes in wastewater treatment, including dissolution, coagulation, precipitation, oxidation, and other processes. The following are the main changes in the use of polymeric iron sulfate in wastewater treatment:

Dissolution: Polyferric sulfate is added in liquid form to wastewater and then dissolved in water. In this process, polymeric ferric sulfate molecules decompose into iron ions and sulfate ions, which play an important role in wastewater treatment.

Coagulation: Chemical reactions occur when dissolved iron ions and sulfate ions interact with suspended or colloidal particles in water. This leads to mutual attraction between small particles, forming larger aggregates. Coagulation is to more effectively remove suspended solids from water.

Sedimentation: The formed coagulant settles into water, forming sludge or sediment. This step is to remove suspended solids from the water and purify the water quality. Sludge can be further disposed of through subsequent treatment methods.

Oxidation: Polyferric sulfate has certain oxidation properties and can undergo oxidation reactions with certain organic and inorganic pollutants. This helps to degrade recalcitrant organic matter and improve water quality.

PH regulation: The addition of polymeric iron sulfate may affect the pH value of wastewater. In some cases, additional pH adjustment steps may be required to ensure that the water quality is within the appropriate range.

Filtration: The settled sludge can be removed through filtration and other methods to further improve the clarity of water.

These changes enable polymeric iron sulfate to play multiple roles such as coagulation, sedimentation, and oxidation in wastewater treatment, ultimately achieving the effects of wastewater purification and clarification.
