Resumé

When virgin filter media is placed in drinking water biofilters, a start-up period of some months typically ensues. During this period, the necessary inorganic coating and bacterial community are established on the filter medium, after which the treated water complies with drinking water criteria. In this study, the start-up of a full-scale biofilter using natural inherent inoculation was investigated using a thorough monitoring approach to document the changes that take occured. Results showed that interrelated physical, chemical and microbiological changes take place during specific phases and in specific strata in the filter medium. With this knowledge, it is possible to identify how to optimize the start-up process, including when and where to inoculate as well as what to inoculate with.
