Understanding the impact of cationic polyacrylamide on anaerobic digestion of waste activated sludge - ScienceDirect
Cationic polyacrylamide (cPAM), a linear water-soluble polymeric compound with a high molecular weight and cationic charges, is widely used in enhancing solid-liquid separation through charge neutralization and interparticle bridging (Aguilar et
Abstract. This study aimed to evaluate the use of cross-linked cationic starch and pregelatinized cationic starch as flocculants in the sedimentation of iron ore tailing slime seeking a less toxic and less expensive alternative when compared

The influence of cationic and anionic polyacrylamides (PAM) on the compressive and shear properties of kaolinite suspensions has been investigated at pH 7. The compressive
- What is powdered activated carbon (PAC)?
- Powdered Activated Carbon (PAC) Systems are primarily used by water treatment plants on either a full time basis or as needed for taste and odor control or removal of organic chemicals. PAC can be fed as a powder using dry feed equipment or as a slurry.
- How can wastewater treatment plants reduce micropollutants in the global water cycle?
- In order to protect aquatic environments and to reduce the presence of micropollutants in the global water cycle, wastewater treatment plants (WWTPs) often implement an additional treatment step. One of the most effective measures is the use of powdered activated carbon (PAC) as an adsorbent for micropollutants.
- Why is PAC used in water purification?
- The addition of PAC will affect the floc characteristics, which will also impact on the separation of the PAC. PAC used in the water purification system makes it possible to react quickly to changes in the quality of raw water. It is the main reason for using PAC in cases when the increase in the concentration of pollutants occurs peri-odically.
- Does PAC increase turbidity in treated water compared to raw water?
- In other dosing strategies turbidity of treated water increased in comparison to raw water. When PAC was dosed before coagulant, regardless of the type of coagulant, the effectiveness of organic contami-nants removal was high.
