Abstract

As water resources are constantly limiting due to excess water consuming and water contamination, research is challenged to present new methods for water saving and reuse. This paper presents the performance of a pilot scale prototype system for advanced wastewater treatment, which combines both GACFs and UF Membrane. The experimental unit has a total operational volume of 7.2 L and consists of a GAC column cascade followed by an UF membrane. Influent flow rates to this system ranged from 0.5 to 6 L/h at residence times of 1.8 – 14.4 h and organic loading rates of 16 -70 mg BOD5/L. Results show high removal efficiencies of organic matter of about 72% as total COD and 87% BOD5, complete denitrification with 86% removal of nitrate and total nitrogen removal of about 60%. Nitrification actually does not take place, as expected in the absence of dissolved oxygen. Average phosphorus removal was about 58%. Neither Total Coliform nor E. coli was detected in the UF effluent water. Fouling of the UF membrane was frequent at high influent rates (3-5 L/h), whereas for lower rates (0.5-1 L/h) use of the membrane was prolonged to about 48 hrs.
