(AIMS Press, 2020-07-10)The performance of experimental batch-reactor loaded with slaughterhouse waste at mesophilic temperature was investigated as well as the inhibition of both ammonia and sulfide concentration in the aqueous phase. The digester ... -
Evaluating the performance of faecal sludge dewatering technologies in urban settings of developing African countries: a review
(Taylor & Francis online, 2024-05-02)Inadequate dewatering technologies are reported as the dominant challenge in handling faecal sludge (FS) within urban settings of most African countries. Studies have been carried out to evaluate the efficiencies of unplanted ... -
Evaluation of recharge areas of Arusha Aquifer, Northern Tanzania: application of water isotope tracers
(IWA Publishing, 2020-10-21)In Arusha urban, northern Tanzania, groundwater contributes about 80% of the water supply. However, elevated fluoride levels and evidence of anthropogenic pollution have been reported in the groundwater around Mount Meru ... -
An Evaluation of Sustainability Potential of Existing Septic Systems: A Fuzzy-Based Indexing Approach
(MDPI, 2022-05-05)In this study, a fuzzy-based indexing approach (FIA) is developed based on a conceptual framework regarding social, environmental, economic, and technical dimensions to evaluate the overall sustainability potential of ... -
Evaluation of the Oxidation Stability of Biodiesel Produced from Moringa oleifera Oil
(ACS Publications, 2011-10-19)Biodiesel is considered as an alternative fuel to petroleum-based conventional diesel fuel. Dependent upon the raw material, biodiesel can contain more or less unsaturated fatty acids in its composition, which are susceptible ... -
Evidence of climate change impacts on water, food and energy resources around Kilimanjaro, Tanzania
(Springer Nature Switzerland AG., 2019-11-08)This review presents research evidence of climate change and anthropogenic impacts on the slopes of Mt. Kilimanjaro and its implications on water, food and energy production (WFE nexus). While there exist divided scholarly ... -
The Exergy Analysis for the Air Gasification in a Hybrid Fixed Bed Gasifier
(Current Journal of Applied Science and Technology, 2021-07-31)Municipal solid waste (MSW) is becoming a concern as population in urban area is increasing. Several disposal methods (landfill and biochemical) have been used. However, waste to energy (WTE) particularly gasification ... -
Experimental analysis of air flow patterns in perfomance of flat plate solar collectors
(African Journal of Agricultural Research, 2015-02-05)Solar drying is one of the promising methods of reducing post-harvest losses in rural areas. Studies have shown that, heat transfer mechanisms in a solar collector influences the performance of solar dryers. This study ... -
