As a high-molecular-weight inorganic coagulant, the efficacy of
polyferric sulphate as a flocculant in wastewater treatment is significantly influenced by its quality. Criteria for assessing this quality include iron content, basicity, density, pH value, and other factors. So what exactly is the density of polyferric sulphate? Let us explore this today!
The density of ferric sulphate polymer essentially denotes the ratio of mass to volume – commonly referred to as specific gravity. Typically, both density and volume undergo certain variations with changes in temperature and pressure. Consequently, precise control over temperature and pressure during production is crucial. Regarding density, a value of 1.3 indicates a compliant product. However, a density reaching 1.45 signifies superior quality. Higher density generally correlates with superior product quality. Consequently, density testing—typically conducted using specialised densimeters—is a standard method for assessing the quality of ferric sulphate products.
In practical application, ferric sulphate polymer reveals itself as a distinctive water treatment agent. It exhibits strong coagulation properties, rapid flocculation effects, the formation of large, compact flocs, and accelerated sedimentation rates. It also exhibits a broad pH tolerance range. Compared to other water treatment chemicals, it requires lower dosage rates. Its distinctive advantages include superior water treatment efficacy, low operational costs, and minimal toxicity. Furthermore, it proves particularly effective in treating specialised water qualities, such as dyeing wastewater and synthetic detergent effluent.
For dyeing wastewater, where raw materials and dyes present complex and variable compositions, traditional biochemical methods alone often fail to meet discharge standards. Our application demonstrates polyferric sulphate's remarkable efficacy in dyeing wastewater treatment. It can replace inorganic flocculants like polyaluminium chloride while achieving comparable purification results with approximately half the dosage. The treated water remains free of secondary-pollution impurities. It also demonstrates excellent performance in treating synthetic detergent wastewater. It delivers comparable purification results while requiring approximately half the dosage. The treated water is free from secondary pollutants. It also demonstrates excellent efficacy in treating synthetic detergent wastewater, which contains challenging substances such as alkylbenzene, petroleum chloride, sodium hydroxide, cyanide, and phosphates. Selecting the appropriate product is essential for effectively removing COD from detergent wastewater. It is widely recognised that polyferric sulphate achieves COD removal rates exceeding 90%, a level unattainable by other flocculants.
