The Industrial and Mining Water Research Unit (abbreviated IMWaRU) is one of several research entities based in the School of Chemical and Metallurgical Engineering at the University of the Witwatersrand, Johannesburg. It provides research as well as supervision to masters and doctorate students within the University, as well as consulting to industry.

Unit Structure

The unit deals with cross disciplinary water issues relating to industry and mining.[1] As such the group includes experts in chemical engineering, microbiology and other sciences.

The unit includes five NRF rated researchers and over 20 masters and doctoral level postgraduate students in the faculties of engineering and science.

Members

The group currently comprises 7 academics (alphabetically - Mogopoleng (Paul) Chego, Kevin Harding,[2] Michelle Low,[3] Craig Sheridan,[4] Geoffrey Simate,[5] Karl Rumbold[6] and Lizelle van Dyk), as well as several postgraduate students.

Location

Richard Ward Building, to the right, home to the Industrial and Mining Water Research Unit.

The unit is housed in several buildings across the University, most notably in the Richard Ward Building on East campus.[7] Additionally, some members are located in the Biology Building on East Campus and have access to laboratories in that building.

They also have access to an outdoor facility on West Campus where constructed wetland, and other outdoor, experiments take place.

Research

2nd floor laboratories of the Richard Ward Building, upgraded in 2013 for use by IMWaRU and others.

The group has a broad range of research publications in the areas as listed below:[8]

Collaboration

The unit works closely with the Centre in Water and Research Development (CiWaRD), a cross disciplinary water research think tank.

Active collaborations include the Schools of Law, Chemistry, Civil and Mining Engineering and the Global Change Institute at the university, in addition to the Helmholtz Centre for Environmental Research in Leipzig, Germany. They have also collaborated with the Universities of Cape Town, Geneva, Queensland and the Pontifical Catholic University of Chile.

IMWaRU has had several Technology Innovation Agency (TIA) projects run through Wits Enterprise.

The unit exhibited with several other groups at Mine Closure 2014.[50]

Presentations

Constructed wetland equipment used in research experiments by the group.

Members of the group have had presentations given at:
