Abstract:
Biodegradation is an effective method for the removal of taste and odour (T&O) compounds from drinking water sources. In this study, the applicability of a moving-bed biofilm reactor (MBBR) as biological treatment step for the control of MIB and geosmin was studied at pilot-scale. After a 3.5 month acclimation period both T&O compounds could be reliably removed by at least 80%. Biodegradation was found to be the dominant removal mechanism with air stripping contributing up to 25% at shorter HRTs. Also sorption of MIB and geosmin onto carriers and biofilm did occur, simultaneously facilitating the biodegradation process. The biodegradation of MIB and geosmin followed pseudo-first-order kinetics.

Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...
