  • Are natural flocculants a sustainable technology for water and wastewater treatment?
  • Finally, the future prospects, challenges and recommendations are also provided in order to advance the developments of natural flocculants to enable them to be a long-term sustainable technology for water and wastewater treatment. 2. Dyes wastewaters Dyes have been used in practically all spheres of daily life since the beginning of mankind.
  • Can microbial flocculants be used in wastewater treatment?
  • For instance, microbial flocculants can be applied in numerous wastewater treatments, however, these materials are low yield and high cost that limits itself development. Therefore, hybridizing flocculant materials with different properties, such as starch based flocculants, can complement each other.
  • Is flocculation a long-term sustainable technology?
  • Flocculation employing natural flocculants is indeed a long-term sustainable technology as it does not require the usage of chemicals, and therefore it is a more desirable option as compared to chemical flocculants (e.g. synthetic organic polymers) , , .
  • Which organic flocculants are used in wastewater treatment?
  • Natural organic flocculants like chitosan, cellulose, tannin, starch, gelatin and their derivatives and microbial flocculants have been investigated for their flocculation mechanism in wastewater treatment.
