Get PriceDoes nonionic polyacrylamide affect the flocculation process of removing clay?
The presence of nonionic polyacrylamide has slight effect on the flocculation process efficiency of removing clay from industrial wastewater. On the other hand, usin g o f prepared flocculent, it was found that the presence of soap in water in large concentrations has a negative effect on flocculation process.
What is nonionic polyacrylamide PAM?
Nonionic polyacrylamide PAM is mainly used for flocculation and sedimentation of various industrial wastewater, and clarification and disposal of precipitation. Many friends have little knowledge of this type of polyacrylamide. Today, I will introduce the characteristics, efficacy, and usage of nonionic polyacrylamide PAM.
What is polyacrylamide used for?
Polyacrylamide and its co-polymers are used as flocculants or coagulants in industrial wastewater treatment .Homo-polymer is used in this application and can be either nonionic, cationic or anionic depending on the types of wastewater needs to be treated. Also polyacrylamide can be prepared either as linear or as cross-linked.
What spectroscopy is used to identify anionic polyacrylamide flocculant?
The anionic polyacrylamide (APAM-T) flocculant was characterized by Fourier transform infrared spectroscopy (FTIR), 1 H nuclear magnetic resonance spectroscopy (1 H NMR), and scanning electron microscopy (SEM). Furthermore, the X-ray photoelectron spectroscopy (XPS) was conducted to measure the elemental composition.
Is non ionic polyacrylamide a water soluble polymer?
Non-ionic polyacrylamide is a water-soluble high molecular polymer or polyelectrolyte. The characteristics of nonionic polyacrylamide PAM can be simply divided into the following three points: It has relatively good water solubility and can be completely dissolved even in cold water.
How is partially hydrolyzed polyacrylamide wastewater treated?
