Researchers in Drexel University’s Environmental Engineering Department are collaborating with American Water to apply a new test that is intended to extend the lifespan of seawater filtering membranes by predicting the growth of damaging biofilm on them. The test, called Bioluminescent Saltwater Assimilable Organic Carbon (AOC), will help to measure the amount of biodegradable organic matter in seawater and enable researchers to predict the level of biological fouling –formation of biofilm- that could occur on the filtering membrane. American Water developed the AOC test, which will also help to reduce Reverse-Osmosis (RO) membrane fouling in the water desalination process.
