What Are the Factors Affecting the Effect of PAM Polyacrylamidem Wastewater Treatment?

Industrial Wastewater Treatment using PAM Polyacrylamide has excellent treatment effects on wastewater with suspended particles, high concentration, positive charge, and neutral or alkaline pH, such as sewage from steel plants, electroplating plants, metallurgical plants, and coal-washing plants. Wastewater treatment is generally divided into production wastewater treatment and domestic wastewater treatment. Production wastewater includes industrial wastewater, agricultural wastewater, and medical wastewater etc. Domestic wastewater is the complex mixture of various inorganic and organic substances generated in daily life, including floating and suspended solid particles, colloids and gel-like diffusing bodies, and pure solutions.

PAM polyacrylamide used in wastewater treatment

As we all know, PAM polyacrylamide is divided into anionic, cationic, and non-ionic types, each type containing many medium models. Different industries have suitable wastewater treatment models. The choice of model is crucial to the effect of wastewater treatment, which is one of the reasons affecting the effect, followed by other influencing factors.

Factors affecting the effect of PAM polyacrylamide wastewater treatment

• The acidity and alkalinity of water have a great impact on the potential of the surface charge of colloidal particles and the property and function of flocculants.

• Water temperature. When the water temperature is high, the reaction rate of flocculants is too fast, and the flocs are very thin. When the temperature is too low, the reaction rate of flocculants decreases, hydrolysis time increases, which affects the treatment capacity.

• Stirring speed and time. When the stirring speed is too fast and the time is too long, large solid particles will be crushed into small particles, and the sedimentable particles will be crushed into non-sedimentable particles. When the speed is too slow, the flocculant cannot fully contact the solid particles in a short time, which is not conducive to the collection of colloidal particles by the flocculant, and the concentration distribution of the flocculant is also uneven, which is not conducive to the role of the flocculant.

Due to the relatively high application cost and various types of PAM polyacrylamide, it is best to choose the best model for wastewater treatment in different industries through experiments, and further adjust the pH range and temperature through experiments, and control the stirring speed and time.
