Water treatment processes from Veolia and their technologies go hand-in-hand with one another. Our technologies and water treatment processes combine to provide both process water for industry and potable water for industry and municipalities. They are:


Water purification package plant

Water purification package plants from Veolia South Africa, also called modular or containerised plants, have fewer moving parts than conventional plants and leave only a small footprint. Similarly to large-scale plants, Veolia provides the key technologies, chemicals and processes so it’s customers can easily achieve both process water and potable water to both industry standards and local and international legislative requirements. They are easily transportable and are designed as a ‘plug-and-play’ solutions.

Water purification technologies

Water purification technologies from Veolia South Africa focus on attaining highly purified water for industrial use – specifically for use in the pharmaceutical, petrochemical and food & beverage industries. However, some of them are also used for other industries, which can be seen in our market segments pages. These water purification technologies are also used to achieve potable water, fit for human consumption, that can be used onsite by industry or sent to municipal infrastructures to help with their fresh water needs if required.

Reverse osmosis plant

Reverse osmosis plants from Veolia are extremely effective in dividing and separating solubles from their solvents. This includes salts, iron and calcium, among many others. Reverse osmosis plants have been helping some cities around the world achieve a reliable potable water source using desalination. Essentially, reverse osmosis plants aid in producing both process and potable water, polishing and demineralisation of water for niche markets, and water recycling and reuse for numerous industries. These plants are also instrumental in achieving ZLD.
