Column design for groundwater hardness removal using cashew nut shells activated carbon with potential application in low-income communities
(2020-01)tigated. Water hardness has a significant impact on groundwater, especially in arid and semi-arid regions, leading to wasted investments in borehole drilling and worsening accessibility to potable water. In many developing ... -
A column design for groundwater hardness removal using cashew nut shells activated carbon with potential application in low-income communities
(NM-AIST, 2020-02)Water hardness has been associated with various human health problems. In many developing countries, groundwater is the main source of drinking water. Water hardness has a significant impact on groundwater quality, ... -
Combination of natural betanidin dye with synthetic organic sensitiser towards dye-sensitised solar cell application
(NM-AIST, 2023-05)Betanidins belong to natural red-purple pigments betacyanins, which experimentally demonstrated good light adsorption in a visible range and might be suitable for the dye sensitised solar cell (DSSCs). Instability is a ... -
Combined reverse osmosis and constant-current operated capacitive deionization system for seawater desalination
(Elsevier B.V., 2014-07-01)There is an increase in the use of water purification technologies to produce the purified water from saline water. The desalination process may either involve the use of a single desalination technology, or may include ... -
Community awareness on fluoride contaminant sources: a case study at Mount Meru slopes in Northern Tanzania
(International Journal of Biosciences, 2019-10-27)A study was conducted around the slopes of Mount Meru in Arumeru district of Arusha region at Ngarenanyuki ward, to update the awareness of the potential routes of human exposure to unacceptable levels of fluoride. ... -
Comparative sorption isotherms and removal studies for Pb(II) by physical and thermochemical modification of low-cost agro-wastes from Tanzania
(Elsevier, 2018-03)Corn and rice husks, agro-wastes available in large quantities in Tanzania, were used to remove Pb2+ from aqueous solution. Husks were used in raw form, pyrolyzed form, and chemically modified form. Material characterization ... -
