Influence of natural organic matter on the deposition kinetics of extracellular polymeric substances (EPS) on silica

► Deposition of EPS on silica surfaces is significantly influenced by NOM. ► Pre-coating silica surfaces with SRHA hinders the deposition kinetics of EPS. ► Pre-coating the silica surfaces with alginate enhances EPS deposition. ► NOM present in solutions decreases the deposition of EPS on silica.
