Abstract The occurrence and severity of cyanobacterial and algal blooms in water supplies has been increasing due to the effects of eutrophication and climate change, resulting in more frequent taste and odour (T&O) events. Conventional treatment processes have been found to be inefficient in removing the two most commonly detected algal T&O compounds, geosmin and 2-methylisoborneol (MIB), though granular activated carbon (GAC) and biological activated carbon (BAC) contactors have achieved high T&O removal rates. Literature on the performance of GAC and BAC for T&O removal in full-scale treatment plants, however, is limited. This review collates and assesses pilot-scale and full-scale studies which focus on removal of geosmin and MIB, with the aim of understanding the factors which influence T&O removal and determining knowledge gaps in the use of GAC and BAC. Age and empty bed contact time (EBCT) were found to have a significant impact on GAC performance, with removal efficiency decreasing with increased age and increasing with longer EBCTs. BAC contactors have achieved higher removal rates than non-biologically active GAC contactors and were not impacted by age, EBCT and/or carbon type. From these observations, implementation of BAC for T&O removal would be favourable; however, further investigations are required to understand full-scale performance of BAC and service life modelling.

Aim at experimenting the micro-polluted characteristic of Huaihe River water, a pilot-scale test by the combination process of ozone/ultraviolet (UV) /biological activated carbon (BAC) filter for advanced treatment of drinking water was applied. The removal efficiency of general pollution indexes by combined process with different ozone dosages (1.0~3.0 mg/L) was investigated. Along with the increase of ozone dosage, the removal efficiency of CODMn and UV254 generally increased in ozone/UV oxidation process; The removal effect of NO2--N by ozone/UV oxidation was obvious; The removal of turbidity and NH3-N was mainly in BAC filter phase; When the ozone dosage was 2.0~2.5 mg/L, the general pollution indexes had gotten satisfying results, thus it was not necessary to increase the ozone dosage.
