| description | 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 impair the efficiency of the membranes but the problem has not previously been well characterised, especially after a full life-span of membrane operation. Veena Nagaraj and colleagues at Murdoch University in Australia investigated biofilms and used genetic analysis to identify the bacteria growing on 14 used membranes, and compared the results with pre-existing contamination on unused membranes. The research revealed that operational conditions favour the growth of specific bacterial populations, predominantly Proteobacteria, but also Bacteriodetes and Firmicutes. The results should assist research to devise new methods to prevent and alleviate the biofouling of desalination plant membranes and maximise the efficiency of their operation. |
