2 Creating water solutions for the mining industry Veolia Water Technologies can provide specialised water systems thanks to our understanding of the unique requirements of mine operations and our worldwide expertise of water treatment. Our solutions focus on technical performance, compliance with process and environmental requirements and longterm cost effectiveness in order to fulfil the most demanding reliability, safety and quality standards essential to the mining industry. Our expertise and innovative technologies can help you meet your mining challenges: To improve productivity by treating raw water surface or aquifer for production process requirements To manage environmental risks by treating contaminated water to achieve water quality suitable for reuse or for safe discharge into the environment To add value to the bottom line by treating sludge streams to recover suspended and dissolved constituents To secure high quality drinking water, even at remote mining sites To cope with production peaks while complying with stringent regulations To guarantee long-term efficiency and costs through operations services High OH&S Standards We place the Occupational Health & Safety (OHS) of our customers, employees and third parties at our workplaces as our highest priority. We are certified to the following Standards by BSI Global: BS OHSAS 18001: 2007 OHS Management Systems Standard AS/NZS 4801: 2001 OHS Management Systems Standard AS/NZS ISO 14001: 2004 Environmental Management Systems Standard AS/NZS ISO 9001: 2008 Quality Management Systems Standard Applications Drinking water applications Set up or upgrade potable water systems, including for sites in remote locations Provide a temporary or emergency supply of water, when there is a breakdown, emergency or planned maintenance need Process water applications Metal recovery, specific ion removal and demineralisation Pre-treatment of raw water for boiler feed, cooling tower water and condensate treatment Contaminated water applications Treatment of contaminated underground water, process water or tailings dam water to produce high quality water suitable for reuse or safe discharge Wastewater applications On site wastewater treatment, turnkey or packaged plant biological treatment for safe discharge into sensitive environment or reuse Reuse water applications Treatment to provide reuse water in stringent conditions to maintain positive water balance on site and reduce water supply stress on mine operations Ensure high quality reuse water for safe operations and minimise maintenance cost
