dc.description.abstractThis study highlighted bioremediation of aquaponics wastewater and its re-use by providing a breeding compartment for the sh, plant and bacteria. The aquaponics wastewater from the sh, bio-remediated water from the bio-lter and water from the plant pots that recycled back to the sh tanks were characterized. An aquaponics setup was made to have three sh tanks and nine plant pots with three different bed media of gravel, periwinkle and palm kernel shell to hold the plant without soil. As the shes grew, nitrite and nitrate concentrations signicantly increased from 0.00 to 10.66 mg/L and from 0.00 to 30.13 mg/L respectively. The plants show a signicant increase to a maximum height growth of 22.86 cm for periwinkle, 20.24 cm for gravel, and 30.48 cm for palm kernel shells bed in each of the beds. However, the palm kernel shells bed yielded the best plant growth measured up to 30.48 cm height. Atomic absorption spectrophotometer (AAS) analysis shows that plants used up essential nutrients like zinc, iron, and potassium from the bio-remediated water after the ninth week. For kinetic study, Line Weaver-Burke plot of reciprocals of the data was plotted to examine the possibility of the reaction tting into the Michaelis-Menten model. V was obtained to be 19.12 % which indicates the minimum max concentration of substrate at which there will be maximum oxidation. K obtained to be 0.97 indicates the s substrate concentration at which half the bacteria's active sites are occupied by a substrate. This conrmed that the reaction in the system follows the rst order reaction so the behavior of the system's reaction can be predicted over a desired time interval; Microbial nitrication shows Michaelis-Menten kinetics.
