secco polyacrylamide

Polyacrylamide raw material acrylamide is a certain toxicity, but polyacrylamide is non-toxic, has been widely used in drinking water, food processing industry, sugar industry.

Generally used in the sugar industry is anionic polyacrylamide, in the sugar juice purification, syrup filtration two links, highlighting its important effect, but in the polyacrylamide, it is inevitable that there will be a trace of unpolymerized acrylamide, so, in the application of time to strictly control the residual monomer content.

The wastewater of sugar industry is the wastewater discharged in the process of sugar making from sugar beet or sugarcane. The wastewater generally contains organic matter and sugar, among which COD and BOD are high. In addition, the waste water contains very high nitrogen, phosphorus, potassium and other elements, which mainly come from the distillation speed, sugar pressing wastewater, ground flushing

Wash water, etc. The treatment of sugar industry wastewater is inseparable from polyacrylamide, in which anionic polyacrylamide plays an important role.

First, anionic polyacrylamide will remove pure sugar water, removing impurities can improve the quality of sugar water;

Second, anionic polyacrylamide can purify the sugar juice, its molecular weight is fixed on the surface of different particles, so that the particles form aggregates and settlement;

Third, anionic polyacrylamide can filter syrup, save processing time, thus improving the efficiency of production and processing.

After years of practice, the anion of polyacrylamide used by general sugar mills is 22-28%, which is suitable for different materials (cane juice, syrup, brown sugar) and different technological processes.
