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.

Lecture honours one of SA’s greatest women leaders
2008-08-22

A member of the national executive committee of the ANC Women’s League, Yolanda Botha, has called on all South Africans to cherish the legacy of Charlotte Maxeke, one of South Africa’s greatest women leaders.

Ms Botha was delivering the first Charlotte Maxeke Memorial Lecture at the University of the Free State (UFS) in Bloemfontein last night, in honour of the pioneering role played by Maxeke in the struggle for human rights, democracy and freedom. The lecture series is a partnership between the Free State Provincial Government and the university.

She was born Charlotte Makgomo Manye on 7 April 1874 at Ramokgopa in the Polokwane district in Limpopo. In 1905 she graduated from the Wilberforce University in Ohio in the USA with a B.Sc. degree, making her the first black South African woman to graduate with a science degree.

She married the Rev. MM Maxeke, a prominent AME minister who had also been educated overseas, and together they collaborated on the compilation and publication of the first AME church hymn book in Xhosa.

Later she became a founder member and president of the Bantu Women’s League, forerunner of the ANC Women’s League. She was an early opponent of the pass laws for black women and an organiser of the anti-pass movement in Bloemfontein.

Charlotte Maxeke died in 1939. Two years later, an ANC conference held in Bloemfontein, passed a “resolution on the women’s section”.

Elaborating on the challenges that women still face, Ms Botha said poverty remains a challenge affecting the majority of women. She called on all women to unite and engage with government to develop a comprehensive strategy for food security and agricultural support programmes to eradicate poverty.
