Biofouling is a major issue in applying NF/RO technologies for wastewater treatment. Biofilm formed on the surface of membranes will cause flux decline and energy waste. In this study, a novel anti-biofouling method that applies D-amino acids to inhibit biofilm formation was investigated. The D-amino acids previously reported to inhibit biofilm formation and disrupt existing biofilm -- D-tyrosine and the mixture of D-tyrosine, D-tryptophan, D-leucine and D-methionine were tested. Pseudomonas aeruginosa and Bacillus subtilis were used as model Gram-negative and Gram-positive bacteria, respectively. D-amino acids had better effect on inhibition of biofilm formation and disruption of exiting biofilm to B. subtilis than to P. aeruginosa. Microtiter plate assay for quantitative biofilm measurement was systematically evaluated and optimized for screening biofilm control agents. This study also showed that D-tyrosine could effectively inhibit organic fouling and P. aeruginosa biofouling on NF90 membrane surface in bench scale dead end filtration experiment.
