Can Polyacrylamide Be Used In Power Plant Wastewater Treatment?
There are many sources of power plant wastewater, which are mainly divided into the following categories: ash washing wastewater, desulfurization wastewater, chemical wastewater and oily wastewater. Polyacrylamide is used in various types of wastewater from power plants. The wastewater from thermal power plants has the following characteristics: the water quality and quantity vary greatly, and there are many types of wastewater classified; the pollutants in the wastewater are mainly inorganic substances, and the organic pollutants are mainly oil; there are many intermittent drainages.

How To Choose Suitable Type of Cationic Polyacrylamide?
The selection of cationic polyacrylamide generally depends on the different sludge to be treated and needs to be selected through experiments. In the experiment, solutions of polyacrylamide with different ionic degrees were prepared, mixed with sludge under the same conditions, and the size of the flocs and the moisture content of the flocs were observed.

What Effect Does Water Temperature Have On Polyacrylamide?
Generally, the operating temperature of polyacrylamide can be below 50℃ and above 20℃, and the effect is ideal. However, if the water temperature in the settling tank is higher, the convection disturbance of the water in the settling tank will be greater. Since polyacrylamide flocculant is a water-soluble polymer, when the temperature is too high during use, hydrolysis is likely to occur.

How To Choose The Right Polyacrylamide Type?
In the flocculation and sedimentation process of sewage, medium-hydrolyzed anionic polyacrylamide is selected; for air flotation of sewage, nonionic polyacrylamideand low-ionic cationic polyacrylamide pam are mostly used; for sludge dehydration, cationic polyacrylamide is widely used.
