| Popis: | Using appropriate laboratory pilot plants we studied phage elimination during sewage treatment by lagooning and activated sludges. Sewage fed into two types of pilot plant was seeded with a somatic coliphage (φX-174) or an F-specific RNA phage (MS2). Samples were taken from inside the biological treatment tanks to follow phages disappearance. The kinetics of their elimination were compared with that of an inert tracer, rhodamine B. Other samples were taken at the outflow to evaluate the efficiencies of phage removal for the two treatment processes. The elimination of MS2 in the absence of any specific solid phase was also studied. Results show that rapid adsorption on solid particles was less marked for rhodamine than for the phages. The regression coefficients calculated for MS2 and φX-174 were, respectively, 0.46 day−1 and 0.37 day−1 for lagooning, and 0.13 h−1 and 0.128 h−1 for activated sludges, whereas those of rhodamine were 0.069 day−1 and 0.024 h−1. Thus elimination of the phages was faster than t... |
