Nonionic Polyacrylamide Application
Jun 26, 2017

In the sludge dewatering part of the choice of sewage treatment agent is the most critical, there are many uncertainties, mutations often occur, Nonionic Polyacrylamide often with a good type of pharmaceutical, but because the scene of water into a hair or sludge generated qualitative change Changes, resulting in poor selection of pharmaceutical failure or effect weakened, this result led to re-extraction of sewage samples back to do with the type of test, which requires pharmaceutical suppliers can not just provide products, but also a better after-sales service , Nonionic Polyacrylamide Under normal circumstances, with a good type of medicine is still relatively stable.

At present, the industrial solid-liquid separation process is generally used with polyacrylamide flocculant, including sedimentation, clarification, concentration and sludge dewatering process, the application of the industry is also more extensive, according to the source of sewage is divided into two types: And industrial wastewater.

City sewage: refers to the sewage discharged into the urban sewage system collectively, while urban sewage also includes domestic sewage and industrial sewage, urban sewage in the choice of polyacrylamide as a flocculant when used, the general use of cationic polyacrylamide, In about 40% to 60%,Nonionic Polyacrylamide  of course, according to the different water quality, have specific problems specific analysis.

Industrial Wastewater: According to the chemical properties of the main pollutants contained in industrial wastewater, it is mainly classified into organic wastewater containing organic pollutants, inorganic wastes containing inorganic pollutants, organic and inorganic materials Mixed wastewater,Nonionic Polyacrylamide waste water containing radioactive material and only contaminated cooling water, and heavy metal wastewater. For example: food or oil processing wastewater is organic wastewater, and mineral processing wastewater and electroplating wastewater is inorganic wastewater.

According to the classification of industrial processing, it can be divided into: metallurgical wastewater, textile wastewater, papermaking wastewater, tannery wastewater, Nonionic Polyacrylamide pesticide wastewater, oil refining wastewater, mineral processing industry, dyeing industry and sugar industry.

Urban sewage and industrial wastewater commonly used activated sludge treatment, biochemical sludge is often a strong hydrophilic colloid, organic content is high, Nonionic Polyacrylamide extremely difficult to dehydrate. With cationic polyacrylamide treatment, with less, high dehydration efficiency, easy to separate.

Alcohol plant wastewater, brewery wastewater, monosodium glutamate wastewater, sugar plant wastewater, meat products factory wastewater, beverage plant wastewater, textile printing and dyeing plant wastewater. The use of cationic polyacrylamide is several times or several times higher than that of anionic polyacrylamide, Nonionic Polyacrylamide nonionic polyacrylamide or inorganic salt. Because such waste water is generally negatively charged.

The choice of polyacrylamide is mainly based on the type of charge of the effluent with the different types of charge. According to the characteristics of water quality, cationic polyacrylamide, anionic polyacrylamide and nonionic polyacrylamide are selected. The process is generally from the laboratory Of the small test, to the factory test, and ultimately determine the product selection, Nonionic Polyacrylamide specific issues specific analysis. No matter what the industry's water quality, the election of the model is the most critical, mutations occur when the event occurs, once the change, we have to calmly, do not just look at the problem itself, to find a solution to their own polyacrylamide Selection is a very experimental process.
