The United Nations University Institute for Natural Resources in Africa (UNU-INRA) is pleased to invite the general public to a special seminar on the topic “Addressing Wastewater Challenges with an African Bio-resource”.
Date: Thursday, 20th August, 2015.
Venue: UNU-INRA conference room, located on the 2nd floor, International House, University of Ghana campus.
Speaker: Dr. Effiom E. Oku, Senior Research Fellow for Land and Water Resources, UNU-INRA.
The aim of the seminar is to share information on a research that assessed the potential of an African grass species, Chrysopogon nigritana, in treating effluents from industrial and “sickwater” from domestic sources. As part of the project, a phyto-engineering treatment plant was set up, using the African species of the vetiver grass with effluents from fertiliser blending companies, quarry sites, cassava processing factories, abattoirs, leachates from on-engineering dump sites, crude oil polluted water and urban wastewater from drainage sites. The comparative results of pre and post-treatments of the effluents and laboratory analyses showed that, the African species of the vetiver grass is capable of reducing toxic heavy metals, including phosphates, arsenic, cadmium and magnesium in effluents from industrial and “sickwater” from domestic sources, to the World Health Organisation / Food and Agriculture Organisation’s (WHO/FAO) or the United States Environmental Protection Agency’s (USEPA) internationally accepted limits of heavy metals in wastewater.
The seminar presentation will share further information on the research output, and also discuss how best the vetiver technology can be adopted in treating wastewater, at both micro and macro levels.
UNU-INRA periodically organises seminars to share information with stakeholders on the Institute’s research findings. This is to help promote the sustainable management of Africa’s natural resources.
