  • Are chitosan-based hydrogels suitable for wastewater treatment?
  • Presently, the application of polysaccharides in drinking water purification and wastewater treatment has been extensively studied [ 73, 74 ], but there is still a deficiency of methodically related reviews on chitosan-based hydrogels for wastewater treatment, particularly in their adsorption of contaminants and oil–water separation.
  • Why is chitosan a good flocculator?
  • These properties endow chitosan with its good flocculation performance, including efficient charge neutralization and bridging effects, in the treatment of various contaminants in water, as most of them have a negative surface charge (Jiang, 2015, Lee et al., 2014, Matilainen et al., 2010).
  • Can chitosan based flocculants be used in water purification?
  • Chitosan-based flocculants can be also combined with other materials such as PAC, Al 2 (SO 4) 3, FeCl 3, montmorillonite, soils and PAM in water purification as coagulant aids or one of main components in composite flocculants (Assaad et al., 2007, Lee et al., 2012, Lee et al., 2014, Li and Pan, 2015, Ng et al., 2012, Petzold and Schwarz, 2014).
  • Why is chitosan important for water purification?
  • Hence, the need for water remediation from different pollutants is a must. Developing different techniques to accomplish water purification is expanding every day. Chitosan is a biodegradable and eco-friendly biopolymer which is extensively used in various applications.
