Polyferric sulfate for organic compounds

The role of polyferric sulfate in deepening coagulation removal is the natural organic matter in water, so it can be seen that the polyferric sulfate can play a good role in organic matter. So what are its effects on organic matter? Let's have a look.

Natural organic matter in water exists in the form of ordinary particles, colloids or melting. Particles form organic matter, such as organic debris, microorganisms, etc., which is very simple after simple coagulation, accumulation and filtration. Doc organic integration (usually) refers to 0. After 45 o'clock film. There is no uniform expression of organic matter in the form of colloidal Hinduists, which may also be macromolecular groups or passing through 0. forty-five μ M filter membrane molecular material.

The form of natural organic compound colloid depends on the deepening of coagulation removal of natural organic compounds, such as compressed double electric layer, electric neutralization, adsorption bridging, coagulation sedimentation network, etc., and the transmission of coagulant dosage, pH value and other factors based on the removal rate of coagulant invasion of variety and nature. The deepening coagulation mechanism for the removal of organic pollutants by ferric sulfate includes the formation of colloidal NOM electroneutralization, the accumulation of humic acid and fulvic acid aggregates, and the adsorption on the surface of metal hydroxide.

In aluminum salt and iron salt coagulants (aluminum sulfate and iron sulfate in each group), under the premise of the same dosage, the effect of polymeric ferric sulfate on removing natural organic matter in water is better than that of aluminum salt. The main reasons are as follows: on the premise of the same dosage, ferric sulfate destabilizes the colloidal particles and contributes to the formation of humic acid and fulvic acid; Aggregation coagulation ferric sulfate sends out 2 times the alkalinity of aluminum sulfate, so that ferric chloride coagulates at the same pH value. When aluminum sulfate is low and the pH value is low, some positive charges are added, which increases the favorable aggregation caused by humic acid. At the same time, it also contributes to the adsorption of metal hydroxide of organic matter; The specific surface area, the number of surface charges and the area of the adsorption active region are different from the surface area and surface charges.

Therefore, through the introduction of the above contents, it can be seen that polyferric sulfate can have a good removal effect on organic matters, so polyferric sulfate can be selected to treat organic matters in water when using to treat water quality.
