The mean values of results from the measured parameters in the samples over the 4 weeks period are as presented in Table I. The last row of
the Table indicates the maximum limits specified by the Effluent Standard (EPA, 2010). The recorded temperature ranged between 31.2 and 32.5
in the phytoremediation process. It is observed that on the average, the turbidity value in the PostPhyto sample is about two-third the initial inlet
one into the wetland. Similarly, reduction is noted in the post-treatment values of nitrate, pH, phosphate and phenolic compounds. The pH
slightly became more alkaline during the treatment, it was observed to have marginally increased from 6.73 in the inlet to 6.76 at the wetland
outlet. Nitrate removal is however at a higher magnitude with a drastic reduction of about 52% in its value after the treatment. The mean
phosphate reduction in the treatment is 8.9% while the wetland shows insignificant removal of 1% phenolic compound after 4 weeks.
