Article Synopsis
  • Intensive human activities have polluted water sources, making treatment essential due to rising populations and water scarcity.
  • This study evaluated the effectiveness of four plant extracts (Agave americana, Carpobrotus acinaciformis, Austrocylindropuntia subulate, and Senicio anteuphorbium) as natural coagulants to remove Microcystis aeruginosa from water, examining how pH and coagulant dose affected results.
  • Results showed these extracts could remove up to 80% of M. aeruginosa, with lower pH levels enhancing effectiveness; they also exhibited low toxicity, particularly S. anteuphorbium and A. subulate, being the least toxic options.

In recent years, the proliferation of Harmful Cyanobacterial Blooms (CyanoHABs) has increased with water eutrophication and climate change, impairing human health and the environment in relation to water supply. In drinking water treatment plants (DWTPs), the bio-coagulation based on natural coagulants has been studied as an eco-friendly alternative technology to conventional coagulants for both turbidity and CyanoHABs removal. Plant-based coagulants have demonstrated their coagulation efficiency in turbidity removal, as reported in several papers but its ability in cyanobacterial removal is still limited.
