  journal={Industrial \& Engineering Chemistry Research},
A homogeneous layer of a single biofilm component (polysaccharides, proteins, and nucleic acids) was studied on an ultrafiltration membrane and its interaction with different cleaning solutions (base, oxidizer, surfactant, and chelating agent) was evaluated by comparing permeate flux, with the base and oxidizer showing the best cleaning performance. The presence of calcium in the feed solution hindered the ability of the cleaning solutions to completely remove the foulants in the absence of a… Expand

Biofilm as a live and in-situ formed membrane for solids separation in bioreactors: Biofilm succession governs resistance variation demonstrated during the start-up period
Abstract Biofilms developed on support materials with large apertures can be used as live and in-situ formed membranes for solids separation in biofilm-based dynamic membrane bioreactors (bDMBRs).Expand
New approach for the removal of mature biofilms formed by wild strains of Listeria monocytogenes isolated from food contact surfaces in an Iberian pig processing plant.
It is concluded that treatments with an enzymatic detergent have a significantly greater impact on the removal of mature L. monocytogenes biofilms, although a further disinfection process would be needed, enhancing even more the treatment effectivity. Expand
Water flushing irremovable biofilms on support material in dynamic membrane bioreactor: Formation, composition, and microbial community.
It is found that both low SRT and repeated water flushing promoted the formation of irremovable biofilms on support materials, and the composition and microbial community between the ir Removable and removable bio Films were significantly different, which differentiated the biofilm adhesion and removability.
