Overview

Demonstrates engineered bacteria reduce biofouling in membrane filtration, highlighting a path for sustainable water treatment.

Key Points

  • The aim is to develop a sustainable solution to biofouling in membrane filtration systems.
  • Engineered quorum-quenching bacteria were constructed using CRISPR-Cas gene editing.
  • A gravity-driven membrane ultrafiltration model was employed for validation.
  • Performance metrics included evaluation of biofilm properties and transmembrane pressure.
  • Transmembrane pressure decreased by 64.5%.
  • Total organic carbon removal improved by 13.2%.
  • Membrane lifespan extended by 16.1%.
  • Annual net profit increase of 31.52% projected for treatment plant operations.
  • Net carbon footprint reduced by 27.43%, equating to 2.96 × 10^5 kg CO2eq.
