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. 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, Michelle Low, Craig Sheridan, Geoffrey Simate, Karl Rumbold and Lizelle van Dyk), as well as several postgraduate students.

The logo of the Unit is in the shape of a drop of water, with the left half representing the blue of water.

The right half of the drop is modified to show grass and how water is linked to all life. Underneath the icon are the letters IMWaRU, while to the right, the name "Industrial and Mining Water Research Unit" appears.

Location

The unit is housed in several buildings across the University, most notably in the Richard Ward Building on East campus. 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

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

• Acid mine drainage (AMD) - methods of reducing, treating and managing AMD.
• Algal Studies - including to clean water, and as a source of biomass for biodiesel
• Biorefineries - the use of biomass for values add product, including obtaining these with dual purpose water treatment.
• Constructed wetlands (CW) - waste water remediation through natural biological processes.
• Ecological Engineering - study of creating and sustaining cohabitation conditions for both humans and their environment.
• Grade Engineering
• Industrial biotechnology - the use of biotechnology in water related applications e.g. for water purification and water reduction.
• Industrial Ecology - the use of sustainability principles in reducing environmental impacts; particularly relating to water.
• Life-cycle assessment (LCA) - quantification and minimisation of liquid/solid/gaseous waste at sites which include food processing, industrial bioprocessing and others.
• Material flow analysis
• Membrane technology
• Nanotechnology
• Ozone - determination of optimal treatment techniques for cooling water purification systems, chemical vs ozone.
• Water footprinting (WF) - quantification and minimisation of water use on, amongst others, mine and paper/pulp sites.
• Wastewater treatment
• and more.

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.
