This product is synthesized with high-purity ferrous sulfate and oxidant, and follows food-grade production specifications throughout the whole process. Its heavy metal content is far lower than industry standards, and it will not introduce additional pollution to water body. It has excellent flocculation speed and precipitation effect, can quickly remove turbidity and chroma in water, and will not change the natural mineral balance of water body. It is compatible with the conventional clarification process of drinking water treatment plants. The packaging adopts food-grade inner lining bags to avoid cross-contamination, meeting the packaging requirements of food safety production.
Total iron content ≥23% (calculated as Fe), basicity 8%-12%, pH value 2.5-3.5 for 1% aqueous solution, water insoluble matter ≤0.2%, ferrous ion content ≤0.05%, lead ≤2ppm, arsenic ≤0.5ppm, cadmium ≤0.1ppm, appearance is off-white to pale yellow crystalline powder, solubility ≥99%, packaged in food-grade PE composite bags of 25kg per bag, stored in a cool, dry and ventilated place, avoiding moisture and exposure to sunlight, shelf life of 18 months.
It is mainly applied to raw water clarification treatment of urban centralized drinking water plants, wastewater treatment of bottled drinking water production lines, advanced treatment of starch wastewater and slaughter wastewater in food processing plants. It complies with the environmental protection and hygiene standards of the food industry, and can be directly used in water treatment links in contact with food, meeting the discharge and drinking water safety requirements without additional post-treatment processes.
