Is Ferric Sulfate The Same As Polymeric Ferric Sulfate
Is polyaluminum chloride acidic or alkaline?
Polyaluminum Chloride (PAC) is an inorganic polymer with a core chemical structure of poly-nuclear hydroxyl complexes (general formula: [Al₂(OH)ₙCl₆₋ₙ]ₘ). When dissolved in water, aluminum ions (Al³⁺) undergo hydrolysis reactions, releasing hydrogen ions (H⁺) that create an acidic solution with a pH value stabilized between 2.0–4.5. This characteristic gives PAC the following advantages
Difference Between Polyaluminum Ferric Chloride And Polyaluminum Chloride
Conditions for continued use after exposure to moisture
If the solid polyferric sulfate only lumps due to moisture, but no obvious oxidation or discoloration (such as no yellowing or redness), it can still be used normally after crushing. When using it, it is necessary to strengthen mixing to promote dissolution and appropriately increase the concentration of the solution to ensure the flocculation effect
What can be used to replace polyaluminum chloride in sewage treatment?
In sewage treatment, polyaluminum chloride (PAC) is commonly used, but the following alternatives can be considered in specific scenarios (such as reducing aluminum residue, adapting to low temperature water quality or cost optimization):
application of polyferric sulfate in aquaculture
Polyferric sulfate (PFS) is used as an efficient water quality and sediment improver in aquaculture. It can significantly improve the aquaculture environment through flocculation, precipitation, oxidation, decomposition and nutrient supplementation. The specific applications are as follows:

PAC color classification and corresponding levels
The color difference of PAC directly reflects its purity level and core components, which are mainly divided into four levels:
