  • How can a drinking water treatment plant improve algae removal efficiency?
  • A few newly-built or expanded drinking water treatment plants improve algae removal efficiency by adding pre-oxidation (pre-chlorination, potassium permanganate and ozone pre-oxidation), air flotation and advanced treatment processes (ultrafiltration membrane, ozone activated carbon filtration).
  • How to remove algae from water?
  • Numerous studies have showed that pretreatment with preoxidants such as chlorine, chlorine dioxide, ozone, or permanganate can enhance algae removal by chemical coagulation processes , , . Chemical coagulation is the committed step in conventional water treatment processes for algae removal .
  • What is algae-based wastewater treatment?
