Abstract

The start-up of an anaerobic fluidized bed reactor was carried out using asingle inoculum (supernatant of anaerobic digester) and later on with multiple inoculum (a mixture of supernatant of anaerobic digester and volatile fatty acid (VFA)) to achieve a faster start-up. Then regular experiments were carried out to study the effect of hydraulic retention time (HRT) on CODremoval (%) and biogas production. The pharmaceutical effluent with COD of2000 to 4000 mg/L was treated in a fluidized bed reactor using an enricher-reactor concept with a hydraulic retention times of 3 (U-f = 6U(mf)) to 24(U-f = 1.5U(mf)) hr. The maximum COD removal (%) of 91.2 and a maximum biogas production of 5.62 L/d were obtained at 24 hr HRT for a maximum COD concentration of 4000 mg/L corresponding to a fluidization velocity (U-f) of 20 m/hr (1.5U(mf)) using a granular activated carbon bed of average size 700mum.
