  • Why is flocculation important in industrial wastewater treatment?
  • Flocculation is an essential phenomenon in industrial wastewater treatment. Inorganic coagulants (salts of multivalent metals) are being commonly used due to its low cost and ease of use. However, their application is constrained with low flocculating efficiency and the presence of residue metal concentration in the treated water.
  • Are polymer-based flocculants effective in treating wastewater from mining industries?
  • However, Sarkar et al., demonstrated the efficacy of naturally abundant polymer-based flocculants/adsorbents for treating wastewater from mining industries [ 102 ].
  • How much PAM based flocculants are consumed in France?
  • In France, for instance, the consumption of PAM-based flocculants is about 15 kt year −1. In particular, the aggregate production uses about 900 t year −1 of PAM-based flocculants (i.e., 6 % of the total consumption) as clarification aid (UNPG 2013).
  • Are plant extracts a useful flocculant?
  • Coagulation/flocculation studies were carried out on water samples taken from local drinking water sources. The results show that the plant extracts effectively remove water turbidity and are disinfecting, therefore may be a potential useful flocculants in near future.
