The Potential of Subsurface Infiltration for the Treatment of Biofil Toilet Technology Effluent

Type: article
Abstract: BTT effluent and sampled at ports spaced at 0.3 m, 0.8 m, and 1.5 m depths. Using the samples, parameters like COD, BOD5, TSS, T-N, NO3-N, NO2-N, PO4-P, and pathogenic indicator microbes were monitored. RLS and SS columns efficiently removed COD, BOD5, and TSS from the BTT effluent below the Ghana Environmental Protection Agency (GH EPA) guideline values. Up to 99% COD removal were observed in RLS column. A two to five log pathogen removal was recorded for the soil columns. The RLS and SS were found to have a high efficacy for contaminant removal with up to 80% of all contaminants being removed at a depth of 0.3 m along the soil columns. Thus the subsurface infiltration system can serve as a promising technology for the BTT effluent treatment. The study recommends the incorporation of infiltration systems to the BTT especially for areas with high water table or clayey soils.
