“…4. Data for mine-water ions were calculated from the mine feedwater quality and quantity desalinated as provided by Buhrmann et al (1999). Raw water ions were estimated from raw water quality data and the specific raw water consumption reported for Eskom at 2000 levels (Eskom, 2000), while treatment chemical salts were approximated for the water treatment operated at the power station (Pather, 2004;Ras, 2011).…”

“…A notable water exchange is the longstanding desalination of excess saline mine water from adjacent coal mines by the Tutuka power station and by Sasol's Secunda facility (Buhrmann et al, 1999;Burger, 2004). Further potential initiatives include an exchange of low total dissolved solids (TDS) waste streams to a water-constrained gold mine for gold recovery from dormant slimes dams and the use of mine water for cooling purposes (Ras, 2011).…”

The increasingly poor quality of South Africa's natural water sources requires industries and power stations to treat raw water extensively prior to industrial use in, for example, boilers. Two different raw water desalination technologies, an existing ion exchange plant and a proposed reverse osmosis intervention, are compared by life cycle assessment for the production of 1 Mℓ of boiler feed water, in the context of the Secunda industrial complex situated in Mpumalanga, South Africa. The proposed reverse osmosis option would perform 22% worse for global warming potential, which relates to the use of coal-derived electricity, but would reduce burdens of the ion exchange option on human toxicity and freshwater aquatic ecotoxicity due to the use of an aluminium sulphate coagulant. Significantly, the assessment predicts the reverse osmosis option to effect a 78% overall reduction in storage of problematic salts, from 599 kg/Mℓ to 133 kg/Mℓ. Notwithstanding the fact that the power generated within the complex and used by the RO process is associated with a high salts burden (mine water is desalinated at the power station), it was found that the reverse osmosis intervention would incur a lower salts footprint than the IX/S technology and would not shift salts burdens.

“…Veil et al (2003) investigated mine water in Pennsylvania and West Virginia/USA, where more than 120,000 abandoned mines and consequently a large number of flooded mine pools are available. At the South African Tutuka Power Station, Eskom mine water (treated by a spiral reverse osmosis plant) is used as cooling water (Buhrmann et al 1999). Among them is the Tremont 31-MW block, which has used the treated Lyken mine discharges since 1986.…”

“…Fortunately, the highest fraction of reclaimed water came from the secondary treatment where organic compounds, suspended solids, and pathogens were substantially partially removed (National Research Council, 2012). It could be utilized for agricultural irrigation, landscaping, civil non-potable purposes, cooling or other industrial applications (Buhrmann et al, 1999;Carr et al, 2011;Gori et al, 2003;Lazarova and Savoye, 2003). However, nutrients, predominantly nitrogen and phosphorus, which can cause eutrophication while being discharged to the environment might not be removed in the conventional secondary treatment.…”

A mini-review on the impacts of climate change on wastewater reclamation and reuse

To tackle current water insecurity concerns, wastewater reclamation and reuse has appeared as a promising candidate to conserve the valuable fresh water sources whilst increasing the efficiency of material utilization. The climate change, nevertheless, poses both opportunities and threats to the wastewater reclamation industry. Whereas it elevates the social perception on water-related issues and fosters an emerging water-reuse market, the climate change simultaneously presents adverse impacts on the water reclamation scheme, either directly or indirectly. These effects were studied fragmentally in separate realms. Hence, this paper aims to link these studies for providing a thorough understanding about the consequences of the climate change on the wastewater reclamation and reuse. It initially summarizes contemporary treatment processes and their reuse purposes before carrying out a systematic analysis of available findings.
