Ammonia Removal from Wastewater Using Both Activated Carbon and Carbon Nanotube

The removal of ammonia from wastewater has been studied using both Activated Carbon (AC) and Carbon Nanotube (CNT) at different conditions i.e., pH, amount of dosage, contact time, shaking speed, and temperature. To enhance the removal process, the adsorbent materials have been impregnated with Fe, Al, and Cu. The maximum removal that has been achieved was 40% with using 2 g of activated carbon impregnated with aluminum oxide at a pH of 10.5 and a shaking speed of 200 RPM for 2 hours. It was shown that the temperature has a noticeable effect on the removal. While only around 21% removal was achieved at 25oC, 40% removal was achieved when the temperature was increased to 70oC with aluminum oxide impregnated AC. These results shows that this method of removal can be used as a pre-treatment since the removal percentage is lower than other available techniques.
