Polyferric sulfate（PFS） is an inorganic polymer coagulant with superior performance. Its morphology is a pale yellow amorphous powdery solid, which is easily soluble in water. The 10% (mass) aqueous solution is a reddish-brown transparent solution with hygroscopicity. Polyferric sulfate is widely used in the purification of drinking water, industrial water, various industrial wastewater, urban sewage, sludge dewatering, etc.
The pH value of solid polymerized ferric sulfate is 4-11 for water body, but the best treatment range is 6-9; 4°C or less). Since solid polyferric sulfate is hygroscopic, what are its storage requirements? Because solid Polyferric sulfate must be dissolved before it can be used. Therefore, the dissolution equipment and dosing equipment should be made of corrosion-resistant materials. Installation, transportation and storage requirements:
1. It should be lightly loaded and unloaded to avoid damage to the packaging;
2. It should not be transported or stored together with toxic and harmful substances, and should be stored in a cool and dry place;
3. The effective storage period of solid products is one year; the storage period of liquid products of water purifier is six months.
