Potential of Moringa oleifera seeds and fuel wood ash as adsorbent of dye and organic matter in wastewater from batik producing enterprises
Treatment of effluents from batik producing enterprises to removal dyes and other impurities is inevitable as these enterprises are becoming ubiquitous in many cities in Tanzania. Wastewater from batik production processes are discharged haphazardly without treatment. In this study, preliminary results on adsorption potential of defatted Moringa oleifera crude seed extract (DMOCSE) and fuel wood ash (FWA) for dye and...

Influence of a quasi-delegated management framework on sustainable distribution of quality drinking water in Umoja Innercore Estate, Nairobi
Managing drinking water in its distribution pathways is one of the main indicators of the quality of service provided to the consumer. Its quality management is important since human health and livelihoods depend on adequate, clean, reliable water supplies. Unfortunately, this is not true to many neighborhoods in developing countries and the quality of water distributed in Umoja Innercore is no exemption. This research...

Intensity duration frequency relationship of maximum rainfall in a data scarce urbanized environment: A case study of the Guma Catchment in Sierra Leone
Rainfall intensity for a particular frequency and duration is one of the most important parameter for the hydrologic design of dam, reservoirs, storm sewers, culverts and many other hydraulic structures. This can be obtained from Intensity-Duration-Frequency (IDF) relationship, which is determined by frequency analysis of rainfall data. The goal of this research is to develop rainfall intensity-duration frequency...

Current methodologies and algorithms used to identify and quantify pollutants in sub-basins: A review
Over the past few years, water quality has been threatened and is vulnerable to various pollutants and climate variables. The deteriorating state of water resources/bodies has been further exacerbated by the impacts of climate change patterns in Southern Africa. Therefore, modelling and predicting the quality of water in sub-basins has become important in controlling water pollution. Remote sensing techniques gained...
