The traditional clay pot can be modernized by including sawdust to produce a ceramic water filter. Ceramic water filters are known to improve the quality of drinking water by inactivating waterborne ...
Assessment of As and Hg in mine tailings and indigenous grass : a case study of non-functional New Union Gold Mine, South Africa

Mundalamo, Tsedzuluso; Gumbo, Jabulani R.; Muzerengi, Confidence; Dacosta, Francis (2015)

The present study was carried out to assess the uptake of toxic metals, arsenic (As) and mercury (Hg), by Cynodon dactylon grass species at New Union gold mine tailings, Limpopo Province, South Africa. The samples were ...
Defluoridation of groundwater using diatomaceous earth : optimization of adsorption conditions, kinetics and leached metals risk assessment

Izuagie, Anthony A.; Gitari, Wilson M.; Gumbo, Jabulani R. (Taylor and Francis, 2015-08-27)

In Sub-Saharan Africa, many rural communities depend on boreholes as the most appropriate source of water supply. Sadly, water from some of the boreholes contains ﬂuoride above the WHO guideline of 1.5 mg/L. Hence, ...
Effects of calcination temperature and solution pH on the defluoridation potential of Al/Fe oxide-modified diatomaceous earth: metal leaching and sorbent reuse

Izuagie, Anthony A.; Gitari, M.; Gumbo, Jabulani R. (IWa Publishing, 2017)

An evaluation of the effects of calcination temperature and solution pH on the fluoride removal capacity of Al/Fe oxide-modified diatomaceous earth was carried out. The sorbent was observed to be most effective and stable ...
