  • Can biopolymer-based flocculants reduce water treatment risk?
  • As biopolymer-based flocculants are of great benefit to reduce the risk of water treatment, researches of new flocculants based on biopolymers are the focus of scholars in recent years. Biopolymer-based flocculants have the potential to scale up practical applications.
  • Does polyacrylamide grafted bioflocculant reduce water pollution?
  • Water pollution contributes to by decreasing the amount of available freshwater. Grafted bioflocculants tend to have excellent wastewater remediation capabilities. The aim of this research was to synthesize, characterize and apply polyacrylamide grafted bioflocculant to wastewater treatment.
  • Which biopolymer has higher flocculation efficiency?
  • In their study, Sinha et al. (2013) also found their graft copolymer (polyacrylamide grafted casein) to have higher flocculation efficiency than the natural biopolymer (casein). When paralleled with some of the conventional flocculants (FeCl 3 and PAM), TMT −1 -g-PAM 2 displayed better flocculation efficiency than FeCl 3.
  • How do biopolymer based flocculants affect repulsion between contaminants?
  • If the electrical property of the biopolymer-based flocculants is opposite to that of the contaminants, the electrostatic attraction makes the biopolymer-based flocculants molecules be adsorbed on the surface of contaminants, resulting in charge neutralization. It decreases the electric repulsion between contaminants.
