  • Are plant based coagulants effective in wastewater treatment?
  • The plant based coagulants (PCB) are used in the treatment of water but they are not effective on industrial scale because of the higher cost as compared to synthetic coagulants. These coagulants are more effective in wastewater treatment, which has low or medium turbidity range (50–500 NTU).
  • What factors affect coagulation processes in water and wastewater treatment?
  • Several factors affecting the coagulation processes in water and wastewater treatment include the types of coagulants, the coagulant dosage, the mixing processes, and the characteristics of the water/wastewater to be treated.
  • Can natural coagulants be used in water treatment?
  • The transition from chemical to natural coagulants can be an alternative solution to minimize the environmental pollution and health risks caused by the use of chemical coagulants [ 9, 10 ]. The use of natural coagulants in water treatment has become imperative due to its biodegradable and environment-friendly nature.
  • Are natural coagulants effective in waste water purification?
  • Molecule bridging, adsorption, and charge neutralization constitute the stages of the treatment process using natural coagulants. The major benefits of natural coagulants in waste water purification are that they are renewable, non-toxic, biodegradable, and cost-effective, and can efficiently remove turbidity [46, 47].
