In the field of wastewater treatment, polymeric ferric sulfate (PFS), as an advancediron-based flocculant, exhibits excellent clarification efficiency, pollutant removalcapacity, and system stability. When polymeric ferric sulfate is dosed into awastewater treatment system, it rapidly interacts with suspended impurities in thewater. The polymerized iron ions contained in PFS can effectively neutralize the surfacecharges of suspended particles, thereby eliminating the electrostatic repulsion betweenparticles and promoting their aggregation. This process generates dense, robust flocsthat are easy to precipitate and separate. As a result, the treated wastewater achievessignificantly improved transparency. For this reason, polymeric ferric sulfate is widely adopted in wastewater treatmentplants as a superior alternative to traditional aluminum-based coagulants, addressingthe limitations of conventional coagulants in terms of flocculation efficiency andenvironmental friendliness.

Wastewater decolorant is a treatment agent primarily used for industrial wastewater, targeting colored components in wastewater. It is a water treatment agent that reduces or removes the chroma of wastewater to achieve an ideal state. Based on the decolorization mechanism, decolorants can generally be classified into three categories: flocculating decolorants, oxidizing decolorants, and adsorbing decolorants. Oxidizing decolorants mainly utilize their strong oxidizing properties to break down chromophoric groups, thereby removing chroma, while adsorbing decolorants remove chroma through adsorption via their own porous structure. These two methods have many limitations and drawbacks, making them unsuitable for large-scale applications. Due to its wide applicability across various fields, flocculating decolorants have become the mainstream product for decolorization treatment. This decolorant can also decompose surfactants and emulsified oils in wastewater through the principles of flocculation and sedimentation. It breaks them down into small particles via electrolysis, which then settle under gravity through flocculation and sedimentation, achieving solid-liquid separation. Its functions include removing suspended organic matter, reducing chemical oxygen demand (COD), eliminating chroma, and additionally reducing the organic load in subsequent biochemical treatment. This wastewater decolorant is mainly used for the decolorization of high-chroma wastewater from dyeing factories and is applicable to wastewater containing reactive dyes, acid dyes, and disperse dyes. Furthermore, it can be used in the treatment of textile, bleaching, dyeing, printing, and dyeing wastewater, as well as industrial wastewater from the pigment, ink, and paper industries.

Polymeric ferric sulfate (PFS) is a high-molecular-weight coagulant widely used in wastewatertreatment. It is synthesized mainly from ferrous sulfate and sulfuric acid, and demonstrates superiorperformance in removing phosphorus, sulfur, SS, COD, and in bleaching applications compared tomany conventional coagulants. Although both polymeric ferric sulfate and ordinary ferric sulfate are inorganic compoundscontaining trivalent iron ions, they differ significantly in structure and properties: Molecular Structure Polymeric ferric sulfate is a macromolecular polymer, whereas ferric sulfate is alow-molecular-weight inorganjic salt.Upon hydrolysis, PFS forms long-chain colloidal species withstrong adsorption and net-trapping capabilities, enhancing its coagulation efficiency. In contrast,ferric sulfate hydrolyzes to simpler, less effective species with weaker colloid-adsorption capacity,which is why it is seldom used as a primary coagulant in sewage treatment.Applications Ferric sulfate is primarily employed as an analytical reagent, catalyst, or mordant in industries suchas medicine and fertilizer production. Its lower cost makes it suitable for certainnon-water-treatment roles. However, it tends to release more free trivalent iron ions, which can becorrosive. Polymeric ferric sulfate, on the other hand, is specifically designed as a high-performance coagulantfor physicochemical treatment processes in wastewater. Its polymeric structure provides betterflocculation, wider pH adaptability, and less corrosiveness compared to the conventional ferricsulfate.
