Dr Mariana Erasmus, SAENSE Platform Manager, says water remediation is vital for both the ecosystem and industries.

KovsieInnovation at the UFS supports innovative research outputs in various ways – one of which is to protect the intellectual property and to register patents where viable. This is in line with KovsieInnovation’s broader aim to create third-stream income for the university. Patent registration is a complex process and the UFS is proud to have the needed expertise to properly facilitate such an endeavour.

The SAENSE Platform

South Africa is a water-scarce country, with many water hungry industries (such as agriculture and mining). “Industrial processes often contaminate water with heavy metals, harmful chemicals, radioactive waste, and even organic sludge,” Dr Mariana Erasmus, SAENSE Platform Manager, explains.

Hence, water remediation is vital for both the ecosystem and industries. One of the key functions of the SAENSE Platform is to offer water-remedial solutions for the (bio)remediation of nitrates, heavy metals, and salts, among others. The platform’s activities and services are supported by undergraduate and postgraduate students and researchers, using Technology Innovation Agency (TIA) funding. TIA is a national public entity that serves as key institutional intervention to bridge the innovation chasm between research and development.

From waste to water

Through the joint effort of two mining companies and the UFS/TIA SAENSE Research Platform, a new treatment for mine drainage (MD) has been developed. This patented B-DAS (Barium – Dispersed Alkaline Substrate) technology effectively treats the major contaminants found in acid, alkaline, or neutral mining wastewater. The aim of the B-DAS system is to provide a passive water-treatment solution with minimum waste production; it can also be a potential pre-treatment for reverse osmosis (RO) to lower the requirements of the membranes and therefore potentially reduce the RO cost.

The success of the patent is that it turns unusable water into water that is fit for agricultural purposes at a reduced cost and increased efficiency.

Prof John Grider, Associate Professor of History at the University of Wisconsin-La Crosse in the USA and a Research Fellow in the Institute for Reconciliation and Social Justice (IRSJ) at the University of the Free State (UFS), has launched a book based on more than a decade of research into the Pacific maritime labour identity. His monograph, entitled A Foreign Voyage—Pacific Labour Identity, 1840-1890, delves into the history of the maritime industry, not only as a vehicle for expanding the processes of capitalism, colonialism, industrialisation, and globalisation, but is also exploring the impact of this industry on the shifts in gender, race, class, and technology.

As a student in Colorado, a homesick Grider tried to connect with his coastal roots via research. “Before I started to explore the maritime history, I thought of the ocean as a type of boundary that you sometimes need to cross. The truth is that globalisation happens on ships.” Prof Grider’s passion for Pacific maritime labour identity generates colourful discussions on the topic. Masculine sailors confronted by technological de-skilling that corroded away their identity, come to life as he talks and writes. “I try to show students that history is more than a story about the powerful few, and that everyday people, who may seem powerless, play a major role in shaping the past and the future.”

This monograph is based on first-hand, previously unpublished accounts of daily life at sea, often from ships’ logs and the diaries kept by the men who sailed them. The culmination of much painstaking research and supporting evidence, this book investigates the complex interplay between gender, class, and race sourced from the narratives of men who found themselves working in the transforming Pacific maritime industry during the mid-nineteenth century. A powerful lesson to be learnt from this fascinating segment of maritime labour history, is adaptability, “especially in today’s rapidly changing labour world”, Prof Grider says.
