4 Total solutions for Africa Large Projects Using both traditional and cutting-edge treatment technologies, Veolia specifies, designs, procures, constructs and commissions large-scale water plants for industries and municipalities. Modular Projects Fully-containerised packaged plants answer to the need for smaller-scale water treatment solutions in remote, independent or decentralised communities and industries. Chemicals From sanitising chemicals and disinfectants to flocculants and chemicals for the optimisation of membrane processes, Veolia s Hydrex chemicals range is tailored to the needs of the African water treatment market. Operations & Maintenance Veolia provides outsourced technical assistance, planned/unplanned maintenance, daily management and other services that help to keep water treatment plants functioning at their peak. Services & Consumables A dedicated Customer Services Division provides field service, spares, membrane manufacture and maintenance contracts, ensuring complete on-going support and optimisation.

5 Implementation Veolia Water Solutions & Technologies South Africa provides customised water and wastewater treatment solutions to municipalities and industry. Turnkey solutions in Africa Potable/drinking water production Domestic wastewater/sewage treatment Seawater desalination Water re-use Industrial process water production Zero liquid discharge of industrial wastes Valuable substance recovery Modular water and wastewater treatment plants Mine water solutions including acid mine drainage

6 Seawater Desalination South Africa s largest desalination plant in Mossel Bay Located in Mossel Bay (400 km east of Cape Town), Western Cape Desalinates 15 mega litres per day 10 mega litres used domestically as potable water 5 mega litres used by PetroSA as process water Total cost: ZAR 210 million (US$ 24 million)

7 The coastal town of Mossel Bay needed urgent drought relief, so we turned to the only consistent water source available the ocean. By taking the salt out of seawater on a large scale, we helped supply enough process water for industry, and fresh water for drinking. Seawater: a viable source of fresh water? Almost one quarter of the world s population lives within 25 km of the coast. 97% of the world s liquid water is seawater. Salt removal explained By forcing salt water through the microscopic holes of a reverse osmosis membrane, the salt stays behind: the membranes act as a filter on a molecular level. Further processing with chlorine ensures the water is sanitised, clear and suitable for irrigation, bathing and even drinking. Using technology to create a resource The Mossel Bay Municipality is able to consistently supply large industrial customers with high-quality fresh water that s suitable for various processes. Residents of the greater Mossel Bay region also have more drinking water in their taps. On-going support Veolia continues to maintain and operate the Mossel Bay desalination plant, which includesthe supply of the Hydrex range of chemicals from Veolia.

8 Municipal Solutions The Durban Water Re-use Project A packaged deal In 2001, Veolia Water Solutions & Technologies South Africa designed, constructed and financed the country s first re-use plant. Located in Durban, the largest city on the East Coast of South Africa Upgrades 50 to 77 mega litres per day Commissioned in May, 2001 Total cost: ZAR 74 million (US$ 8.8 million) Public Private Partnership (PPP)

9 Potable water generation and municipal wastewater treatment from Veolia help communities around the world to better manage water resources. Recently, a lot of emphasis has been placed on wastewater reuse, which provides large volumes of industrial process water at lower prices. It is an innovative environmental concept, as municipal wastewater re-use means less stress on fresh water sources, and wastewater streams are less polluted. Domestic sewage as a resource to industry Some industrial processes don t need high quality water. Instead, they rely on large quantities to ensure a high and constant throughput. By upgrading or reclaiming grey water from municipal sewage systems, we are able to secure a constant water supply that matches the necessary quality specifications. Upgrading municipal wastewater Sewage contains high levels of organic matter, carbon, nitrogen, phosphorus and other suspended particles. Activated sludge processes break these impurities down into a form that s easily filtered or clarified, leaving behind water of a near-potable standard. Veolia s flagship municipal plant Some of Durban s largest industrial water consumers, including the Mondi and Sapref refineries, are able to maximise their output, knowing their water needs are taken care of. The city s municipality is further able to divert potable water away from industrial customers to supply previously-unserviced communities instead. The benefits to the environment by reducing the amount of discharged sewage are also long-lasting.

10 Zero Liquid Discharge Valuable mineral recovery at Ambatovy Mine With an extraction capacity of 25,6 tons per hour, this is the largest crystallisation project ever designed in Africa, and one of the largest in the world. Recovery of saleable minerals from waste streams Contain 100% of polluting waters within plant walls Re-use water on-site and significantly reduce fresh water intake

11 Aimed at the mining and heavy industrial sectors, Veolia Water Solutions & Technologies South Africa supplies turnkey extraction plants that drive profitability and minimise damage to the environment. Turning waste into fertilizer with evaporation Ambatovy Mine in Madagascar, a producer of nickel and cobalt, needed a solution to extract ammonium sulphate left behind by the main refining process. The answer was to dry the effluent stream, leaving the ammonium sulphate behind in a waterless and manageable form that can be sold to the agricultural sector as fertilizer. Extreme energy efficiency The plant is equipped with an energy recovery system which harnesses steam from the drying process and converts it to electricity. This helps power the extraction plant, keeping energy requirements as low as possible.

12 Modular solutions The Langstrand Holiday Resort in Swakopmund, Namibia uses a containerised trickling filter plant to re-use sewage as irrigation water. This frees up high-quality potable water for use by visitors and residents. The Katimo Mulilo Filtration Plant Upgrade is designed to produce potable water from the Caprivi River System at a rate of 2,6 mega litres per day. Installed on a Zambian copper mine each container produces potable water at a rate of 0,43 mega litres per day. Over the years, additional containers have increased total production to 1,7 mega litres per day. The Elisenheim Housing Development near Windhoek has acquired a trickling filter plant capable of turning municipal sewage into water suitable for gardening and greening functions. Designs allow for future growth.

13 Using state-of-the-art technology that was developed in Africa for Africa, Veolia Water has helped a number of remote mine camps, villages and industrial plants throughout sub-saharan Africa by supplying packaged plants for wastewater treatment and for potable water production. High-quality water for the pharmaceutical industry is also available with Veolia s range of modular solutions. Plug in, switch on Packaged plants offer highly efficient solutions to smaller communities water needs. They are pre-assembled, containerised and transported to site, where they are simply plugged in and switched on.
