Abstract
Wastewater is a crucial component of the environment. With municipal wastewater that
contains organic matter which is harmful to both the environment and the people. High
levels of BOD5, TSS and phosphates present pose a risk on both aquatic life and to the
population if not properly handled as these deplete dissolved oxygen therefore need to
be treated to NEMA permissible limits of discharge. This study assessed the use of
bamboo activated carbon in the tertiary treatment of wastewater effluent from Lubigi
stabilization pond putting into consideration of the maturation pond as the wetland
130m downstream, the mean values of BOD5, TSS and orthophosphates were found to
be 100mg/L, 140mg/L and 43mg/L which higher than NEMA discharge limits of 50mg/L,
100mg/L and 5mg/L respectively. The study also evaluated the effectiveness of
activated carbon in waste water effluent treatment where its adsorption behavior was
described based on different depths of columns. The 30cm depth demonstrated the
highest percentage removals of BOD5 at 80%, TSS at 81% and Orthophosphates at 71%
which put the concentrations below the permissible limits.
