dc.description.abstractNitrification removes ammonia and Nitrite-Nitrogen (N0i-N) from aquaculture w a stew at u but lead to increase in the amount of Nitrate-Nitrogen (NCh-N) in the system. NOj-N though not toxic to fish at low concentration affects growth and yield at higher concentration thus making further denitrification of the waste water a necessity. This study investigated Polypropylene bio-block (PP) and Palm Kernel shell(PK) as biofilter media for the denitrification columns were used. Wastewater from African catfish (Clarias gariepinus) monoculture facility was ueat* “S"IS ' determine media. Selected water quality parameters were measured in effluent wastewater an lofi Ic,fi L ,moved,. the change in water quality. 'The denitrification efficiency was determined using and Volumetric N Percentage ( ./ oJn conversion rate(VNR). Data obtained were analyzed using t-test. The parameters in the filtrates were within the range recommended for aquaculture, water reuse and discharge into the environment, NO3-N in filtrates was reduced to 45 mg/L in PP and 25 mg/L in pk in the denitrification system.en_US
