Introduction
Total solutionsfor Africa
Large ProjectsUsing both traditional and cutting-edge treatment technologies, Veolia specifies, designs, procures, constructs and commissions large-scale water plants for industries and municipalities.
Modular ProjectsFully-containerised packaged plants answer to the need for smaller-scale water treatment solutions in remote, independent or decentralised communities and industries.
ChemicalsFrom 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 & MaintenanceVeolia provides outsourced technical assistance, planned/unplanned mainte-nance, daily management and other ser-vices that help to keep water treatment plants functioning at their peak.
Services & ConsumablesA dedicated Customer Services Division provides field service, spares, membrane manufacture and maintenance contracts, ensuring complete on-going support and optimisation.
Veolia Water Solutions & Technologies
South Africa provides customised water
and wastewater treatment solutions to

Implem
entation
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)
Seawater Desalination
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.
The Durban Water Re-use ProjectA packaged dealIn 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)
Municipal Solutions
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 re-
use, 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.
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
Zero Liquid Discharge
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.
Modular solutions
The Langstrand Holiday Resort in Swakopmund, Namibiauses 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.
Installed on a Zambian copper mineeach 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 Katimo Mulilo Filtration Plant Upgradeis designed to produce potable water from the Caprivi River
System at a rate of 2,6 mega litres per day.
The Elisenheim Housing Developmentnear 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.
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. They feature
few moving parts, are affordable to maintain, and are exceptionally
easy to operate.
Made-to-order solutions
Veolia Water Solutions & Technologies South Africa designs and
assembles packaged plants to suit each application’s unique
requirements, whether for potable, process or waste water. Factors
include the type of influent, and the legislated effluent standards.
