Study of the efficacy of the membranes produced on a laboratory scale for filtration: a proposal to improve the water quality of the hydrographic sub-basin of Ribeirão das Pedras, Diamantina, MG (Brazil)

Chitosan-based membranes developed for water filtration demonstrated promising efficacy in absorbing heavy metal ions, offering a potential solution to improve the water quality of the Ribeirão das Pedras sub-basin in Diamantina, Brazil. The study, conducted by Amaral et al. (2019), addresses the environmental impact of population growth and technological development on local water resources, particularly concerning heavy metal pollution from historical mining activities. Researchers prepared membranes using chitosan biopolymer and tested their filtration capacity with water samples collected from the sub-basin. While the membranes showed efficiency in removing pollutants, further investigations are recommended to refine formulations and conduct seasonal sampling for comprehensive assessment. This approach highlights the potential of biopolymer-based filtration systems as a sustainable method for mitigating heavy metal contamination in degraded aquatic ecosystems.
