    A comparative analysis of coconut, palm frond and palm stem fibres as erosion control materials on embankments
    (U. P., 2009) Egwuonwu, C. C.; Uzorije, A. P.
    The research focused on the use of fibres from coconut pud, palm stem and palm frond in erosion control on embankments. It compared single layer performance of the three fibres on three different slopes and a double layer performance of the coconut fibre. Two coconut fibre nets and a single net each for the palm stem and palm frond were used with a cell dimension of 2cm x 2cm and a boundary dimension of 360cm x 122cm. The fibres were in turn placed over a model of soil embankment in a soil bin. Rain was simulated for 30 minutes over the protected soil and the amount of soil loss deter mined. This soil loss was compared to the loss from the unprotected slope. The single and double layered coconut fibre were found to be more effective in reducing soil loss compared with the control experiment and fibres from palm frond and palm stem. For instance, for a slope of 3%, the soil loss from the single and double layered coconut fibres were 279.4g and 204.3, respectively, compared to 1051.6g, 322.80g and 310.60g for the unprotected soil, the palm stem fibre and palm frond fibre, respectively.

    Evaluation of the effects of industrial wastewater discharge on surface water (A case study of Nigeria breweries Plc Enugu)
    (U. P., 2012-09) Egwuonwu, C. C.; Uzoije, A. P.; Okafor, V. C.; Ezeanya, N. C.; Nwachukwu, M. U.
    The need to undertake an evaluative effect of industrial wastewater discharge on surface water with a case study of Nigerian Breweries Plc Enugu into the Ajali River was borne out of the need to ascertain the level of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total suspended Solids (TSS) etc and other characterized effluent been discharged into the water body that determines the level of use and quality of this water for irrigation purposes, human consumption and safe ecological habitation of aquatic lives. To achieve this, laboratory analysis was carried out on the Ajali River and the wastewater discharged from the industry and it was confirmed not to have exceeded the benchmark for required discharge of wastewater into streams and rivers as stipulated by some regulatory bodies. In conclusion, treatment measures and regulatory policies were suggested to checkmate the abuse of this water bodies and the danger it might likely pose to aquatic ecological system if regulatory standards were not complied with.
