|Abstract: ||Freshwater scarcity has prompted farmers in developing countries to rely on wastewater for agriculture.
However, the concentrations of heavy metals in the wastewaters are found to be above the WHO/FAO
recommended thresholds. This inherently presents concern particularly as it relates human health.
Although, several conventional wastewater treatment technologies exist; their applications are limited by
high procurement, operation and maintenance costs. Currently, studies on biomass wastes as low cost
adsorbents are gaining momentum. In this study, coco-peat was considered for heavy metals removal. In
this context, batch experiments were carried out in triplicates at 3 different contact times and pH. After
2hr of contact time at pH9, the coco-peat was proven to have Cr removal efficiency of 91.6% against
73.2% using an activated bone char; and 95.0% for Pb(II) against 91.2% for the bone char. This
suggests that the use of coco-peat can provide cost effective means for metal removal from industrial
