Novel FGBAC reactor for controlling the leakage of microfauna in drinking water treatment

In order to reduce the microfauna leakage risk from a granular biological activated carbon (GBAC) reactor which employs granular activated carbon (GAC) as adsorption media in drinking water advanced treatment, a novel fiber and granular biological activated carbon (FGBAC) reactor which employs both GAC and activated carbon fiber (ACF) as adsorption media, was developed. The results showed that the species composition of microfauna leaking from FGBAC reactor is almost similar to that leaking from GBAC reactor, however the densities of microfauna leaking from FGBAC reactor is reduced by 26%-81% compared to those leaking from GBAC reactor. In addition, compared to GBAC reactor, FGBAC reactor can increase the removal efficiencies of chemical oxygen demand (COD) and turbidity by 7% and 10%, respectively, during the stable operation period of reactor.
