Nonionic Polyacrylamide The Most Critical
Jul 14, 2017

In the sludge dewatering part of the choice of sewage treatment agent is the most critical, there are many uncertainties, mutations often occur, often with a good type of pharmaceutical, Nonionic Polyacrylamide 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, Nonionic Polyacrylamide 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, Nonionic Polyacrylamide 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, Nonionic Polyacrylamide 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, Nonionic Polyacrylamide inorganic wastes containing inorganic pollutants, organic and inorganic materials Mixed wastewater, 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, Nonionic Polyacrylamide it can be divided into: metallurgical wastewater, textile wastewater, papermaking wastewater, tannery wastewater, pesticide wastewater, Nonionic Polyacrylamide 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, extremely difficult to dehydrate. Nonionic Polyacrylamide With cationic polyacrylamide treatment, with less, high dehydration efficiency, easy to separate.

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, Nonionic 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, specific issues specific analysis. No matter what the industry's water quality, the election of the model is the most critical, Nonionic Polyacrylamide 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.
