WebJul 8, 2024 · Further, a good biocarrier should have low density, a suitable surface for quick biofilm immobilization, and good structure to protect biomass against shear and sloughing (Hirai et al. 2001; Chaudhary et al. 2003). In wastewater bioremediations, the biocarrier is recommended to have high mechanical resistance because it will face different ... WebAug 31, 2024 · The structure of biofilms in drinking water systems is influenced by the interplay between biological and physical processes. Bacterial aggregates in bulk fluid are important in seeding biofilm formation on surfaces. In simple pure and co-cultures, certain bacteria, including Methylobacterium, are implicated in the formation of aggregates. …
