Ammoniacal nitrogen removal in synthetic wastewater using seaweed-based ionic liquid and Bacillus spp.

Ammoniacal nitrogen (AN) is a hazardous component and a pollutant in rivers
that is challenging to be treated using conventional chemical treatment. The
purpose of the project was to remove the AN in synthetic wastewater using a
seaweed-based ionic liquid and Bacillus spp. Bacterium, which is required to
achieve the Department of Environment (DOE) environmental quality (industrial
effluent) requirement 2009. It is set at 20 ppm AN for Standard B area. The
Standard B is a water quality indexed set by the DOE to ensure the effluent
discharge from industry. A denitrification and ion exchange process occurs in the
bioreactor that remove the ammonia ions. The process variables used to evaluate
the removal efficiency are pH and temperature while taking into account the
COD, BOD and sludge of the effluent. The pH used was between 6 to 8 and a
temperature that varies between 30oC to 40oC. Furthermore, to evaluate the effect
of pH and temperature during the biological treatment process of ammonia
removal. The optimum pH and temperature values set as design parameters are 7
and 37oC, respectively. The result was then used as a constant to study the
optimum condition for the bacteria either in aerobic and anaerobic condition. It
was found that the aerobic condition was the best condition. The ammonia
removal rate was 94% with a final concentration of ammonia at 5.8 ppm treated
using 12.0 g of bacteria for 24 hour in a bioreactor.
