Influence of land use change on nitrate sources and pollutant enrichment in surface and groundwater of a growing urban area in Tanzania
(Springer Nature Switzerland AG., 2021-01-31)
In the present study, 3-year (1997, 2008 and 2017) satellite images as well as different hydro-chemical parameters, nitrogen and oxygen isotopic composition of nitrate were used to examine the impacts of land use and land ...
Regeneration and carboxymethylation of cellulose and its derivatives: application assessment for brewery wastewater treatment
(Springer Nature Switzerland AG., 2021-02-13)
Coagulation–flocculation technique is usually employed in wastewater treatment by applying conventional inorganic materials such as alum and ferric chloride. Due cost to environmental challenges associated with the use of ...
Farmer's appropriation of system of rice intensification practices in water-scarce irrigation schemes in Northern Tanzania
(Springer Nature Switzerland AG., 2021-02-08)
The system of rice intensification (SRI), advocates new ways of rice cultivation which challenges farmers’ knowledge and skills to the extent that they are required to learn, experiment and integrate new principles to suit ...
Comparison of blue and green water fluxes for different land use classes in a semi-arid cultivated catchment using remote sensing
(Elsevier, 2021-08)
Study area
Kikuletwa catchment, Upper Pangani River Basin, Tanzania.
Study focus
This study compared yearly blue and green water fluxes using four different methods: Senay’s method (SN) (Senay et al., 2016), van Eekelen ...
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 ...
The Influence of Fertilizers on the Behavior of Fluoride Fractions in the Alkaline Soil
(Elsevier, 2021-08-23)
It has been established that fluoride bioavailability in the soil is defined by the form which it exists rather than the amount of total fluoride. In the soil, fluoride exist in different fractions such as water soluble ...
Reconstructing the Changes in Sedimentation and Source Provenance in East African Hydropower Reservoirs: A Case Study of Nyumba ya Mungu in Tanzania
(MDPI, 2021-08-08)
This study aimed to reconstruct the sedimentation rates over time and identify the changing
sources of sediment in a major hydropower reservoir in Tanzania, the Nyumba ya Mungu (NYM).
Fallout 210Pb measurements were used ...
Clay-based ceramic materials for water de-fluoridation
(NM-AIST, 2021-08)
Long-term consumption of water with fluoride concentration above the WHO recommended
limit of 1.5 mg/g may cause fluorosis. Low-income communities living in fluoride endemic
regions are more affected as they cannot afford ...
Heavy metals risk assessment of water and sediments collected from selected river tributaries of the Mara River in Tanzania
(Springer Nature, 2021-06-25)
This study investigated the levels of Pb, Hg, Cr, Cd, and As in water and sediments from the tributaries of the Mara River,
Tanzania. Pollution risk of water and sediments was investigated using seven indices and fve ...
Integrated Capacitive Deionization and Humidification-Dehumidification System for Brackish Water Desalination
(MDPI, 2021-11-15)
A hybrid capacitive deionization and humidification-dehumidification (CDI–HDH) desalination system is theoretically investigated for the desalination of brackish water. The CDI system
works with two basic operations: ...
