The thorny issue of membrane biofouling in membrane bioreactors (MBR) calls for new effective control measures.Herein, D-amino acid (DAA) was employed to mediate MBR membrane biofouling by inhibiting biofilm information and disintegrating formed biofilm.Different DAA control ways involving membrane property, DAA-adding timing, and DAA-control mode were explored through experiments and the 7 Piece Queen Poster Bedroom multiple linear regression model and the response surface methodology.

The optimized DAA control ways were acquired, involving DAA used as an active agent, and the DAA-adding timing of 4 h cultured before running, as well as both hydrophilic and hydrophobic membrane, resulting in an approximately 40.24% decrease in UofA the membrane biofouling rate in comparison with the conventional MBR.DAA is an efficient membrane biofouling mediating approach for MBR under optimized control ways combination and a facile solution for solving membrane biofouling in actual membrane systems.
