Experimental studies on stratification were conducted a waste stabilization pond system at the University of Nigeria, Nsukka, Nigeria. This was done to ascertain effect due sunlight parameters. An experimental approach adopted which involved pouring wastewater into glass column apparatus and exposing for 7, 14, 21 days. The statues 16 physicochemical microbiological parameters investigated in t...

There has been a paradigm shift towards reclamation of wastewater from high cost to low cost effective technology for treatment of sewage and resource utilization for economy driven activities.Under appropriate conditions, sewage fed fisheries would reduce the cost of fish production by utilizing the sewage induced natural plankton and become cost effective because of savings through chemical f...

Rock filters are an established technology for polishing waste stabilization pond effluents. However, they rapidly become anoxic and consequently do not remove ammonium-nitrogen. Horizontal-flow aerated rock filters (HFARF), developed to permit nitrification and hence ammonium-N removal, were compared with a novel vertical-flow aerated rock filter (VFARF). There were no differences in the remov...

This study reports the biomass accumulation, plant nutrient concentration, and uptake rates of plants in a constructed floating wetland (CFW) installed for sewage treatment application Australia. Plant accumulation was estimated based on field samplings throughout duration study. Analysis samples each species also completed to estimate mean tissue content. The concentration were then used total...
