Purification of drinking water with polymeric ferric sulfate
Polyferric sulfate (PFS) is a new, high-quality, and efficient inorganic polymer flocculant widely used in the field of drinking water purification due to its outstanding performance in water treatment. The following is a detailed analysis of the purification of drinking water using polymeric ferric sulfate:
1. Purification principle
The process of purifying drinking water with polymeric ferric sulfate mainly relies on various mechanisms such as coagulation, adsorption, oxidation, and precipitation. It can rapidly hydrolyze in water to generate highly charged multi-core complexes, which aggregate colloidal particles and suspended solids in water into larger particles (i.e. flocs) through electrostatic attraction, bridging, and cross-linking. Subsequently, these flocs rapidly settle under the action of gravity, thereby achieving effective removal of pollutants.
2. Main advantages
Efficient water purification: The coagulation formed by the aggregation of ferric sulfate settles quickly and can quickly remove suspended solids, colloidal substances, and organic matter from water; It has significant purification effects on slightly polluted, algae containing, low-temperature, low turbidity, and high turbidity raw water; It can effectively remove heavy metal ions such as lead, cadmium, chromium, etc. from water, ensuring water quality safety.
Improving water quality: The water purified by polymeric ferric sulfate is clear and transparent, with significantly reduced chromaticity and turbidity; Having multiple effects such as decolorization, deodorization, sterilization, and algae removal, it enhances the sensory quality and safety of drinking water;
Economical and practical: The dosage of polymeric ferric sulfate is relatively small, and the processing cost is low; Compared with traditional flocculants, polymeric ferric sulfate can significantly reduce operating costs while achieving the same treatment effect.
Strong adaptability: Polymeric ferric sulfate adapts to a wide range of pH values in water (411), with an optimal pH range of 69, and has low corrosiveness to treatment equipment; Suitable for drinking water treatment under different water quality conditions, including slightly polluted water sources, algae containing water sources, etc.
Safe and environmentally friendly: Polyferric sulfate is non-toxic and harmless, and will not cause harm to human health; After decomposition, it mainly produces iron hydroxide, which is easy to remove from water and does not cause secondary pollution.
3. Precautions for use
Dosage control: The dosage of polymeric ferric sulfate should be reasonably determined based on water quality conditions and treatment needs to avoid excessive use and excessive iron ion residue in the water.
PH adjustment: Before using polymeric ferric sulfate, the pH value of the water should be tested and adjusted as needed to ensure that it is within the optimal working range.
Mixing conditions: Good mixing is a prerequisite for achieving efficient coagulation. Therefore, after adding polymeric ferric sulfate, an appropriate mixing method should be used to ensure that it is fully mixed with the water. Storage and transportation: Polyferric sulfate should be stored in a cool, dry, well ventilated warehouse, away from sources of fire and heat. During transportation, avoid severe collisions and direct sunlight.
Polymeric ferric sulfate, as an efficient, economical, safe, and environmentally friendly water purification agent, has broad application prospects in the field of drinking water purification. Its unique coagulation performance, significant water quality improvement effect, and wide applicability make it the preferred solution for drinking water purification. However, key factors such as dosage control, pH adjustment, and mixing conditions also need to be taken into account during use to ensure optimal water purification performance.
