Alternative tanning technologies and their suitability in curbing environmental pollution from the leather industry: A comprehensive review.
(Elsevier Ltd., 2020-04-18)Chrome tanning remains the most favourite technology in the leather industry worldwide due to its ability to produce leather with attributes desirable for high-quality leather such as excellent hydrothermal stability, ... -
Anaerobic treatment of tannery wastewater using ASBR for methane recovery and greenhouse gas emission mitigation
(Elsevier, 2017-10)The objective of this study was to develop and optimize a pilot scale Anaerobic Sequencing Batch Reactor (ASBR) for the treatment tannery wastewater and reduction of greenhouse gas emission. The performance of the pilot ... -
Analysis of Different Techniques for Improving Performance of Flat Plate Solar Collectors for Fruits Drying
(Tanzania Journal of Engineering and Technology (TJET), 2014-06)Fruits drying had become a broader technology in fruits and vegetables value addition. The technology is reported to be a promising way of dying without incurring higher cost but its adaptation has not been feasible in ... -
An Analysis of Fuel Properties of Fatty Acid Methyl Ester from Manketti Seeds Oil
(Taylor & Francis Online, 2014-11-20)The fatty acid methyl esters (FAME)produced from vegetable oils, animal fats, or waste oils known as biodiesel has attracted attention as possible replacement of fossil fuels. The fuel properties of biodiesel are similar ... -
Analysis of Macro- and Microplastics in Riverine, Riverbanks, and Irrigated Farms in Arusha, Tanzania
(Springer Nature Switzerland AG., 2021-11-16)Microplastics and macroplastics have been reported in different urban rivers and agricultural soil across the globe. However, the interlink between them has not been previously assessed. The present study evaluated the ... -
Analysis of spatio-temporal climate variability of a shallow lake catchment in Tanzania
(IWA Publishing, 2020-04-06)This study analyzed the trends and spatio-temporal variability in rainfall and temperature, and the length of the rainy season (LRS) in the Lake Manyara catchment, Tanzania, covering a period between 1988 and 2018 using ... -
Antibiotic-resistant microbial populations in urban receiving waters and wastewaters from Tanzania
(Elsevier, 2023)Antimicrobial resistance against certain medications in the pathogenic microbial community is globally increasing due to the continual discharge and disposal of pharmaceuticals in the environment. The phenomenon resulted ... -
Application of modified lignocellulosic materials as green flocculants for brewery wastewater treatment
(NM-AIST, 2021-03)Coagulation–flocculation technique is usually used in wastewater treatment by employing conventional inorganic materials such as alum and ferric chloride. Due to environmental challenges associated with the use of inorganic ... -
The application of nutrient budget models to determine the ecosystem health of the Wami Estuary, Tanzania
(Elsevier, 2018-04)Using the LOICZ and the UEE models we estimated the nutrient budget in the Wami River estuary, Tanzania, to better understand the functioning of the ecosystem and assess its health. We found that during the wet season, ... -
Application of rice and corn husk biochar for removal of heavy metal ions from industrial wastewater
(NM-AIST, 2020-01)This study investigated the removal of heavy metal ions from industrial wastewater by using rice and corn husk biochar. The choice of the materials was influenced by their largest surface area, plentiful functional groups ... -
Approaches to the mitigation of ammonia inhibition during anaerobic digestion – a review
(IWA Publishing, 2020-06-03)The digestion process of organic waste rich in high ammonia content has always been a gridlock during methanogenesis process. The free ammonia may increase inhibition/toxicity, which in turn affects the microbial community ... -
