Biofouling in Membrane Bioreactors—Mitigation and Current Status: a Review

Application of psychrotolerant quorum quenching Planococcus versutus sp. L10.15T to membrane bioreactors for biofouling control at low temperatures

“…Biofouling reduces membrane permeability and increases the number of chemical cleaning and membrane replacement, leading to an increase in the operating costs of MBR processes and potential impacts on the environment due to disposal of used chemicals. [1][2][3] Through quorum sensing (QS), which is densitydependent cellular signaling, microorganisms can form biofilms. Cells secrete and sense signaling molecules (e.g., N-acyl homoserine lactones or AHLs) to detect their population density.…”
