Unformatted text preview: eous solution. Studies were carried out in four pH medium with two different standing times. The concentration of the metals in the filtrate was determined using flame atomic absorption 3+ spectrophotometer (FAAS). From the results, it was found that SDMTC was able to removed >90 % Cr , 2+ 2+ 2+ Pb and Ni in basic medium while for Hg , 87.94 % was removed in acid medium. However, only a 4+ 5+ 6+ small portion of metals such as for V , V , Cr can be removed in acid medium. From the findings, it was observed that most of the heavy metals were effectively removed by SDMTC. ENV-O26 DEGRADATION PROFILE OF PHENOL IN SEQUENTIAL BATCH REACTOR Farah Khan, Mohammad Zain Khan and *Suhail Sabir Environmental Research Laboratory, Department of chemistry, Aligarh Muslim University, Aligarh-202002, India Email: Compact well settling granules were cultivated for degrading 3.9 kg m d of phenols. Formed granules were studied qualitatively using SEM and it was found that a large number of bacterial types including bacterial rod, cocci, and diatoms were dispersed in the extracellular polymeric substance (EPS). Degradation studies show that initially the removal rate of phenol was fast but later on it becomes slow. -1 Low concentration of 50, 100 and 200 mg L phenol comes down below detection limit in about 170 min -1 of the SBR cycle but high concentration of 400 and 650 mg L took around 240 min for complete removal. This study demonstrates the utilization of aerobic granulation for treating high concentration of phenol and other xenobiotics. -3 -1 100 3rd ICYC 2010 Universiti Sains Malaysia ENV-O27 23rd-25th June 2010 STUDIES ON BIODEGRADATION OF 2,4-DICHLOROPHENOL IN A SEQUENCING BATCH REACTOR M. Z. Khan, F. Khan and *S. Sabir Environmental Research Laboratory, Department of Chemistry, Aligarh Muslim University, Aligarh-202002, Uttar Pradesh, India E-mail: Aerobic granules had been successfully cultivated in a SBR for degrading DCP at a higher organic load of -3 -1 0.42 kg DCP m d . Stable and compact granules were obtained after 70 days of SBR operation. Final -1 -...
