Panel Discussion in Water & Sanitation Africa Magazine – Sept/Oct 2016
What contracts is QFS currently undertaking in support of water conservation and water demand management (WC/WDM)?
HS On the supply side, QFS is busy with three secondary effluent treatment plants for various municipalities. These solutions generally employ a form of pretreatment and then an ultrafiltration process, followed by a reverse osmosis process in certain instances. This method of treating secondary effluent is a highly effective way of saving water . Our most recent secondary effluent treatment plant was installed in Ballito, KwaZulu-Natal – we achieved some truly impressive results, recovering 91.5% of the plant’s original feedwater.
Can you provide an example where QFS approached WC/WDM creatively?
QFS is proud to have been involved in numerous water-saving solutions for the industrial and mining sectors. For example, the implementation of a gas-energy-mixing (GEM) system as the core technology at a major poultry abattoir in Rustenburg saw the successful treatment of 5.25 Mℓ/day of effluent. This process not only results in a major saving for the client (in terms of penalties) but it also opens up further treatment and reuse options. There are also numerous industrial process water treatment solutions installed where QFS’s solutions are effectively reusing millions of megalitres of water per year .
Why is WC/WDM essential in South Africa and how can it be implemented effectively?
South Africa’s water scarcity and droughts provide a stark reminder as to how valuable and scarce clean water actually is. QFS plays a significant role in many communities across South Africa, in terms of providing real and immediate solutions that enhance people’s lives through access to clean water .
