Abstract

A laboratory set up was used to determine the treatment capacity and effectiveness of bio-treatment system, which consists of a gravel-sand pre-treatment layer followed by a natural peat layer as the primary filter medium to treat kitchen wastewater by percolation. The filter column contained a 50 cm layer of peat lightly compacted to a density of 0.150 g/cm3 and supplied with 10 cm kitchen wastewater per day. The treatment gave the following reductions: SS, 72%; CODtot, 37%; BOD5, 40% and NH+4 -N, 87%. The effluent had a pH of 6.6-6.7. The physical properties of the peat did not appear to be significantly affected by the applied densities of a kitchen wastewater percolation (α = 0.05), as suggested by the voids ratio - applied pressure plots, which shows relatively unchanged compression characteristics pre- and post- filtration. However, the XRF test results show that Silicon Dioxide (SiO2) and Aluminium Oxide (Al2O3) increased after filtration. It was also shown in the study that peat can be potentially used for the removal of pollutants, with the post-filter water quality parameters complying well within the limits of Standard B effluent stipulated in the Environmental Quality Act 1974 (Sewage and Industrial Effluents, 2009). Thus, peat media can serve as a sustainable, effective and economical option for the filtration of kitchen greywater.
