The viscosity and activity of high purity polyacrylamide are temperature dependent, so dosage and application effectiveness are also affected by seasonal temperatures. The dosage of high purity polyacrylamide varies in different seasons. Due to the temperature in winter, the viscosity of polyacrylamide is very small and the activity is relatively small, so more investment is needed to achieve the same purification effect as before, while summer is not required. But there is more rain in summer, so it is necessary to pay attention to the change of sewage quality and discharge, so that the flocculation effect and economic benefits.
High purity polyacrylamide as clear water agent, the application method of polyacrylamide is to dissolve polyacrylamide in clear water, and then mix for about 1 hour, completely dissolve polyacrylamide. Then, dissolved polyacrylamide is added to the purified water. If polyacrylamide is used in printing and dyeing and pharmaceutical industries, the method of application of polyacrylamide is different from that of purification agent.
Screening tests for high purity polyacrylamide flocculants are often necessary. After the suitable polyacrylamide flocculant is selected in the laboratory, it should be tested on the sludge dewatering unit. Different sludge dewatering equipment put forward different requirements on the condensation of polyacrylamide during operation. Therefore, field engineers should timely check and adjust the variety, concentration, addition amount, input point and other output of flocculants according to the conditions of dehydration equipment.
Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N. It is a hard glassy solid at room temperature. The products are liquid glue, latex and white powder particles, translucent beads and flakes. Good thermal stability. Can be dissolved in water in any proportion, aqueous solution is uniform transparent liquid. After long-term storage, the solution viscosity will decrease due to slow degradation of polymer, especially when the storage conditions are poor.  Polyacrylamide, as lubricant, suspension agent, clay stabilizer, oil displacement agent, water loss reducer and thickener, has been widely used in drilling, acidification, fracturing, water plugging, cementing and secondary oil recovery, tertiary oil recovery. It is a very important oil field chemical.Learn more
Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. It is a light yellow amorphous powdery solid and easily soluble in water. 10% (mass) aqueous solution is red-brown transparent solution and hygroscopic. Polyferric sulfate is widely used in drinking water, industrial water, all kinds of industrial waste water, municipal sewage, sludge dewatering purification treatment.Learn more
