| Summary: | This final report is prepared to report the whole progress of the studies of anaerobic
treatment of pharmaceutical wastewater. The project analysis done focused on
monitoring the performance of upflow anaerobic sludge blanket (UASB) reactor to
treat the pharmaceutical wastewater. Two reactors with different operating
temperatures, mesophilic (35±l°C) and thermophilic (54±1°C) were used. The sludge
chosen for anaerobic reactors was taken from UTP Sewage Treatment Plant. The aim
of this project is to determine the optimum operating condition of the reactors and
also to monitor the performance of reactors in removing the COD with application of
different Organic Loading Rates (OLR) and Hydraulic retention times (HRT). The
pharmaceutical wastewater was divided into two strength based on COD
concentrations which, low strength (300-500 mg!L) and high strength (1700-2000
mg!L ). Based on wastewater strength and the hydraulic retention time, the period of
the works is divided by five phase with different OLR ranges. The OLR was increase
from 0.07 to 0.56 kg COD/m3d. The hydraulic retention times (HRT) was ranged
from 5 to 3 days. The reactor performance was monitored for 211 days. Phase 1 to 2
consist of low strength wastewater while Phase 3 to 5 consist of high strength of
wastewater. The highest percentage of COD removal for mesophilic reactor was 95%
while for thermophilic reactor, the percentage removal was 93%. The methane
productions occur at range of 50-300 mL for both of the reactors. The Phosphorus for
both effluents was 10-40 mg!L. The Annnonia Nitrogen for both effluents was 5-14
mg!L. During phase 4 the reactor failure incident occurs at mesophilic reactor causing
its instability to remove COD. Anaerobic reactor has high percentage of COD
removal efficiency and the methane produced can be beneficial to industry. |
