Steel

ArcelorMittal South Africa, Vanderbijlpark

Among the largest zero effluent discharge (ZED) steel plants in the world, Veolia operates all water-related infrastructure and manages the chemical dosing requirements of 60 water systems in nine separate site locations.

The contract includes the supply of approximately 100 tons of Hydrex™ water treatment chemicals each month. These include chemicals for boiler treatment, cooling water treatment, coagulants and flocculants, anti-scalants and disinfectants.

Mining

Evander

Veolia’s O & M contract at Evander Gold Mine helped increase efficiency and reduce its overall costs at its on-site treatment plant. The contract includes the supply of 12 new treatment solutions, including: new chemical dosing stations; flocculants, coagulants, anti-scalants and micro-biocide chemical treatment; a semi-automated duplex flocculent plant; and coagulant plants.

This new solution improved the entire water circuit for the mine. Overall TDS and iron concentrations were reduced, chemical consumption has been optimised and the mine equipment performs more reliably – ultimately running more efficiently and lowering overall maintenance costs.

AngloGold Ashanti (Ghana)

AngloGold Ashanti contracted Veolia to optimise water management at its Iduapriem open pit gold mine. Veolia provides management and operational expertise to ensure proper water treatment and discharge compliant with the Ghana EPA effluent discharge requirements. Site-wide operations were also optimised with a two-stage water treatment process including ozonation and reverse osmosis.

Power Generation

O&M Lesedi / O&M Letsatsi

Veolia provides monthly service of the RO plants that supply the water for cleaning the solar plant’s photovoltaic cells and drinking water onsite. This includes CIPs, routine maintenance, media replacement and breakdown assistance.

Food and Beverage

Distillation plant, Stellenbosch

Since 2016 and as part of a 10-year Build, Operate, Transfer (BOT) agreement, Veolia manages a 1 000 m3 effluent/day anaerobic water treatment plant in the Stellenbosch area.

South Africa’s first Biobulk® Wastewater Treatment plant, the facility treats approximately 8.6 tons of COD each day, harvesting the biogas that is generated within the Biobulk® CSTR (Continuous Stirred Tank Reactor) that is used to power the site’s boilers.

Dairy, Humansdorp

Veolia executes the operations and maintenance requirements for the resource recovery plant at a dairy in Humansdorp in the Eastern Cape.

The plant uses Memthane® anaerobic digestion, UF filtration and membrane desalination processes and related water-conditioning chemicals. The anaerobic digester produces biogas from the COD for use as an energy source in a biogas boiler with a design capacity of 19.6 ton COD/day.

Food processing plant, Durban

At one of South Africa’s largest food manufacturing plants in the world, Veolia provides full operations and maintenance for a water recycling plant that provides high-quality treatment of the factory wastewater and rainwater harvested on site.

Veolia manages the dissolved air flotation, biological, membrane bioreactor and reverse osmosis treatment of the plant that recovers approximately 70% of all process water.

3 food and beverage plants, Johannesburg, Parow and Durban

Veolia assisted one of South Africa’s largest food and beverage producers operate their plants and help reduce production downtime at three production sites across South Africa.

Our solution was a 24-hour operational service, providing the facilities with an in-house technical service and the supply of all water treatment consumables, as well as operational teams to operate the facilities.

Food and beverage plant, Mossel Bay

As part of a design, build, operate and maintain contract, Veolia manages a 600 m3/day resource recovery plant for a leading multinational food and drinks company at its Mossel Bay Factory.

The plant treats an average COD content of 3 907 mg/L, recovering approximately 260 m3/day of purified water with an average conductivity of 148 μS/cm, clarity of 0.13 NTU and COD content of 5.23 mg/L – a 99% overall COD removal and 58% water recovery.

Soft drink manufacturing plant, Durban

Veolia provides operational services for two process water treatment plants for one of the world’s biggest beverage producers in Durban. This 24-hour service includes all laboratory functions for analysis compliant to client specification and chemical supply for all applications within the scope of the water plant.

Wingoc (Windhoek)

Following its design and build of the 5 000 m3/day Ujams industrial wastewater treatment plant, near the City of Windhoek’s northern industrial zone, Veolia was contracted to operate and maintain the plant through a 21-year contract period.

It will manage the plant’s entire water treatment cycle, from the screening and de-gritting of incoming wastewater before entering a membrane bioreactor, to UV disinfection and odour removal before the treated effluent is released from the plant.
