WebApr 14, 2012 · The framework guiding current biological research on control of fouling now appears firmly in place, with investigations focusing on the reception and transduction of settlement- and metamorphosis-inducing cues, and on organismal adhesives and their interaction with the substratum (Clare et al. 1992). WebOct 27, 2016 · The last option to handle biofouling once it has already occurred is membrane cleaning which contributes to 5–20% of the operating cost. Membrane cleaning involves physical cleaning, backwashing, …
