Plant biomasses for defluoridation appropriateness : unlocking their potentials
(Research Journal in Engineering and Applied Sciences, 2014)
Fluoride and fluorosis are endemic to many countries including Tanzania. Performances of different materials
for use in water defluoridation systems have been reported. Some of these materials are; alum, oxides and
hydroxide ...
Energy Recovery routes from Municipal Solid Waste : A case study of Arusha-Tanzania
(Journal of Energy Technologies and Policy, 2014)
A study of energy recovery from municipal solid waste was undertaken. The energy content of the solid waste is
12MJ/kg. The elemental composition shows that the municipal solid waste contains 50% and 5% of carbon and
hydrogen ...
Water hardness removal by coconut shell activated carbon
(Science Publishing Group, 2014-08-30)
The present study reports the water softening by adsorption of hardness ions onto Coconut Shell Activated
Carbons (CSAC). Characterization of CSAC was identified by FT-IR and SEM techniques. Batch experiments were ...
Potential of municipal solid waste, as renewable energy source : a case study of Arusha, Tanzania.
(International Journal of Renewable Energy Technology Research, 2014-06)
This paper presents the study of municipal solid waste (MSW) as a potential source of renewable energy in Arusha
city. The city of Arusha annual average MSW generated was estimated at 43,772 tonnes. Characterization ...
Energy Recovery from Municipal Solid Waste
(Regional Collaboration Conference, 2014-07)
Energy flow analysis and thermal degradation of municipal solid waste was carried out using differential
scanning calorimetry and thermo-gravimetric analyzer at heating rates of 10 K/min, 20 K/min, 30 K/min
and 40 K/min ...
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 ...
Environmental Contamination By Radionuclides And Heavy Metals Through The Application Of Phosphate RocksDuring Farming And Mathematical Modeling Of Their Impacts To The Ecosystem
(nternational Journal of Engineering Research and General Science, 2014-07)
Most of rock phosphates contain radioactive elements and heavy metals because theyoriginate from phosphate deposits.
The application of these rock phosphates may result to the transfer of these dangerous materials into ...

(SciencePG, 2014-09-10)
Recycling and reuse of solid waste has a number of benefits in the overall process of solid waste management.
First, it reduces the amount of waste that has to be disposed off; be it in landfills or otherwise. In this ...
Effects of wastewater characteristics on fish quality from integrated wastewater treatment system and fish farming in Urban Areas, Tanzania
(Scientific Research Publishing, 2014-09-10)
Availability of suitable water is one of the most important limiting factors for development of sustainable
aquaculture in the urban areas. As a consequence, the use of wastewater effluents for aquaculture is on the rise ...
