Evaluating the level of ammonia and sulfide in the liquid phase during anaerobic digestion of slaughterhouse waste operating at mesophilic scale digester—the impact of inhibition and process performance
(AIMS Press, 2020-07-10)
The performance of experimental batch-reactor loaded with slaughterhouse waste at mesophilic temperature was investigated as well as the inhibition of both ammonia and sulfide concentration in the aqueous phase. The digester ...
Synthesis and FTIR Characterization of Mg-Hydroxylapatite Derived from Dolostone with High Dolomite Mineral Content
(University of Dar es Salaam, 2020-08-24)
We present the synthesis of magnesium-substituted hydroxylapatite starting from locally available
dolostone. The apatite was prepared by a reaction between heat pre-treated dolostone powder with
phosphoric acid, maintained ...
Performance of water filters towards the removal of selected pollutants in Arusha, Tanzania.
(University of Dar es Salaam, 2016)
This paper presents the findings of a study carried out to investigate the efficiency of selected
common water filters in the removal of Escherichia coli, organic matter and fluoride. Additionally,
the Total Suspended ...
Effect of mixing ratios of natural inorganic additives in removing ammonia and sulfide in the liquid phase during anaerobic digestion of slaughterhouse waste
(Elsevier, 2021-06-01)
In this study, the efficacy of inorganic additives in the removal of total ammonia nitrogen (TAN) and sulfide in the aqueous phase of slaughterhouse waste undergoing anaerobic digestion in the batch reactor was investigated. ...
Fenton-mediated solar-driven photocatalysis of industrial dye effluent with polyaniline impregnated with activated TiO2-Nps
(Elsevier, 2024)
Various integrated technologies have been investigated for the remediation of heavily polluted industrial dye
effluent. Also, more than 70 % of these dyes are known to be solely azo dyes used in the textile industry ...
