Patents
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.

A new publication, Fractional Operators with Constant and Variable Order with Application to Geo-Hydrology, will be published later this year, on 1 November 2017. The author, Prof Abdon Atangana, from the Institute of Groundwater Studies at the University of the Free State, said the book proposes new techniques for groundwater remediation, including guidelines on how chemical companies can be positioned in any city to avoid groundwater pollution.

Focus of the book
Prof Atangana said researchers and practitioners interested in groundwater modelling and remediation from applied mathematical and geo-hydrology backgrounds, will benefit from reading this book.

According to Elsevier, the book provides a physical review of fractional operators, fractional variable order operators, and uncertain derivatives to groundwater flow and environmental remediation. It presents a formal set of mathematical equations for the description of groundwater flow and pollution problems using the concept of non-integer order derivative. Both advantages and disadvantages of models with fractional operators are discussed.

“Researchers and practitioners
interested in groundwater modelling
and remediation from applied
mathematician and geo-hydrology
backgrounds, will benefit from
reading this book.”

About the author
Prof Atangana specialises in applied mathematics, groundwater modelling, fractional calculus and their applications, methods for partial differential equations, methods for ordinary differential equations, iterations methods, asymptotic methods, perturbations methods, and numerical method for fractional differential equations, uncertainties analysis. He has participated in 18 international conferences, organised six special sections and symposiums in international conference in Europe, Africa, Asia and USA, and has been invited as plenary speaker in eight international conferences. He also serves as editor on 20 international journal of mathematics and applied mathematics and editor-in-chief of two international journals of applied mathematics.
