Removal of arsenic in a sand filter coupled with zero valent iron
(Elsevier, 2023-06-22)Arsenic (As) in wastewater has negative effects on the environment and human health, hence As containing wastes must be handled properly. Given the accessibility of metallic iron, studies investigating into the potential ... -
Removal of fluoride and pathogens from water using the combined electrocoagulation-inline-electrolytic disinfection process
(IWA Publishing, 2023-07-01)The consecutive removal of fluoride (defluoridation) and pathogens (disinfection) in drinking water through combined electrocoagulation-inline-electrolytic disinfection (EC–ECl2) process with aluminum and dimension-stable ... -
Striding towards self-sustainability using aluminium from Tanzanian Kaolin for combination tanning system
(Dresden-Germany, 2019)Sustainability is a key factor which controls future leather manufacture. Developing several new technologies is one of the primary agendas for sustainability. However, developing countries are facing several challenges ... -
Influence of duct configurations on the performance of solar-assisted heat pump dryer for drying tobacco leaves
(NM-AIST, 2023-08)nadequate storage facilities and preservation techniques lead to a decrease in the quality of agricultural products. Application of modern processing techniques has reduced post-harvest losses of agricultural crops. ... -
A quantity-quality tradeoff: Water quality and poverty assessment of drinking water sources in Southern Tanzania
(NM-AIST, 2023-06)Regardless of being essential for human survival, access to potable water is still a problem in many rural African communities with increasing exposure to waterborne illnesses. This study aimed at establishing accessible ... -
Experimental investigation of the variation in the potential of selected natural rocks as thermal energy storage materials
(NM-AIST, 2023-08)Fossil fuels cause greenhouse gas emissions and are perceived to deplete, hence the use of renewable energy is considered crucial. These renewables include the use of solar thermal energy in concentrated solar power (CSP) ... -
Characterization of bird, reptile, and insect community diversity in constructed wetlands and waste stabilization ponds across Tanzania
(Elsevier, 2023-11)Wastewater treatment systems, such as Constructed Wetlands (CWs) and Waste Stabilization Ponds (WSPs), have untapped biodiversity enhancement and development potential. Birds, insects, and reptiles, which are displaced by ... -
Effects of zero-valent iron on sludge and methane production in anaerobic digestion of domestic wastewater
(Elsevier, 2023-12-08)Iron metal (Fe0) materials enhance the performance of anaerobic digestion (AD) reactors to remove pollutants. Most research focused on the materials' mechanisms and effectiveness in enhancing AD. However, there is scant ... -
Assessment of dairy wastewater treatment and its potential for biogas production at Tanga fresh limited
(Tanzania Journal of Science, 2016-03-16)The extent of pollution of dairy wastewater treated in a septic tank and its potential for biogas production was investigated. Performance of the existing treatment system was assessed through characterization of both raw ... -
Eggshells – assisted hydrolysis of banana pulp for biogas production
(2017-01-27)In this study, pretreatment of banana pulp using eggshells in both calcined and un-calcined forms to examine the extent of hydrolysis was conducted. Reactor CO containing banana pulp and inoculum but with no eggshells added ... -
Distribution of organic carbon: possible causes and impacts in the Pangani River Basin ecosystem, Tanzania
