Liquid polyferric sulfate
introduction:

Application scope of liquid polyferric sulfate:


It is widely used in the purification treatment of urban drinking water and industrial circulating water, as well as the purification and sludge dewatering treatment of industrial wastewater and urban domestic sewage in chemical industry, petroleum, mining, paper making, printing and dyeing, brewing, steel, coal gasification, paint, leather, pharmaceutical, food, electroplating and other industries. It is suitable for phosphorus removal or sludge hydrophobicity improvement in domestic sewage treatment plants;


How to use liquid polyferric sulfate:

1. The dosage can be determined according to the different turbidity of raw water. Generally, for turbid water (turbidity is 100-500mg / L), 30-50kg can be used per thousand tons. For non drinking water, the dosage of high turbidity industrial sewage can be appropriately added.

2. In the process of industrial wastewater treatment, the first-class polyferric sulfate is diluted to 1-2 times of water solution. When the concentration of source water is high and the amount of treated water is large, it can be directly added. Then according to the results of laboratory simulation test, according to the better process conditions and dosage, after full stirring and coagulation sedimentation, the clarified effluent can be obtained.

3. The water treatment plant can also be diluted 2-5 times before dosing. According to the nature of raw water, the dosage can be determined by production debugging or beaker experiment, depending on the proper amount of alum formation. Other dosage used in water plant can be used as reference. Under the same conditions, the dosage of this product is about the same as that of solid polyaluminum chloride, which is 1 / 2-1 / 3 of that of solid aluminum sulfate. If the original liquid product is used, it can be calculated and determined according to the concentration of the corresponding reagent, which is roughly determined by the weight ratio of 1:3.
