A woman of impact, quality and care - Dr Lentsu Nchabeleng.

Dr Lentsu Nchabeleng currently serves as the Deputy Director in the Gender Equality and Anti-Discrimination Office within the Unit for Institutional Change and Social Justice at the University of the Free State (UFS). She manages the functions of the office to deliver high-quality services that advance gender equality and anti-discrimination based on human-rights principles.

What is the best thing about your job?
To bring about positive change by using collective individualism to make a collective impact on the university community. This includes recognising diverse views that fall outside the norm to solve issues relating to gender inequality. Thus, every engagement and response that takes place can help create change.

What is the best and worst decision you have ever made?
The best decision I have ever made was to listen to my inner voice and tuning into the wisdom of my body. The worst decision I have ever made was to negotiate my worth and value, which at that particular moment I thought were synonymous.

What was/is the biggest challenge of your career?
There are so many challenges. I don’t know where to begin.

What does the word woman mean to you?
Being a woman, to me, means a lot of things. It means being a force to be reckoned with. The embodiment of resilience, courage, and love.

Which woman inspires you, and why?
My mother inspires me. She’s an inadvertent feminist. I feel connected to more women through her because of her ability to visibilise the presence of women in all spheres of life. She carries her identities – mom, sister, wife, teacher, friend, grandmother, gardener, leader, listener – with so much ease and I admire her for that.

What advice would you give to the 15-year-old you?
Other people’s perception of you ain’t none of your business.

What is the one self-care thing that you do? 
Watering my roses helps me relax and recharge. I have recently learned the importance of silence and it’s benefits to the mind and body. I usually take 15 minutes every day to sit in stillness and self-reflect. This helps me to delve deeper into my value system and needs, which helps activate myself and social awareness.

What makes you a woman of quality, impact, and care?
I would say that my ability to be vulnerable, to accept my weaknesses, my strong sense of independence and speaking my truth, makes me a woman of quality, impact, and care.
 
 


I cannot live without … my family.
My secret weapon is … it will not be a secret weapon if I reveal it …
I always have … a bottle of water.
I will never … take my life for granted. 
I hope … to see the end of the gender pay gap.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
