  • Are plant-based alternatives to metal ion coagulants becoming more environmentally friendly?
  • Becci Bragg, from the Science and Optimisation team at South West Water, demonstrates how plant-based alternatives to metal ion coagulants are being introduced and tested at wastewater sites. Over the last 10 years, the use of metal ion coagulants has been increasing within wastewater treatment, but there is a trend towards more environmentally friendly alternatives.
  • Do chemical and natural coagulants improve wastewater treatment performance?
  • Treatment performances by chemical and natural coagulant have been reviewed on various types of wastewater with different success rates.
  • What is the difference between chemical coagulants and natural bio-flocculants?
  • Chemical coagulants/flocculants are conventionally applied in wastewater treatment and derived from chemically/petroleum-based materials. Natural bio-flocculants are extensively explored on the past few years and sourced from natural materials.
  • How effective are organic coagulants in removing turbidity?
  • Among the novel organic coagulants, PE-2 exhibits remarkable effectiveness in removing turbidity, TSS, COD, and BOD from sugar industry wastewater, while chitosan demonstrates efficacy in TOC and orthophosphate removal in brewery wastewater. CTAB proves highly effective in removing various toxic metal ions from wastewater.
