Characterisation and comparison of bacterial communities on reverse osmosis membranes of a full-scale desalination plant by bacterial 16S rRNA gene metabarcoding

Biofouling: Biofilms and microbes on desalination membranes The diverse microbial populations on seawater desalination plant membranes have been characterised after full operational lifecycles. The membranes were used for seven years to purify water by reverse osmosis. Biofouling can seriously impai...
