Metallic iron for safe drinking water provision: Considering a lost knowledge
(Pergamon, 2017-06-15)
Around year 1890, the technology of using metallic iron (Fe0) for safe drinking water provision was already established in Europe. The science and technology to manufacture suitable Fe0 materials were known and further ...
Water defluoridation by Fe (III)-loaded sisal fibre: Understanding the influence of the preparation pathways on biosorbents’ defluoridation properties
(Elsevier, 2019-01-15)
Defluoridation properties of two Fe(III)-loaded plant biomass (Fe(III)-activated sisal fibre (Fe(III)-ASF) and post-alkalized Fe(III)-ASF (PA-Fe(III)-ASF)) distinguished by preparation pathways through exclusion/inclusion ...
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. ...
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 ...
