Water Technologies

Veolia Water Technologies South Africa has water treatment technologies for all municipal and industrial requirements. We design, build and commission world-class water management solutions for every water and wastewater treatment application to local and international quality standards.

Our range of technologies provides treatment for municipal water in full-scale design and build projects or via water techno packages (packaged plants). Solutions for industrial water treatment are provided via packaged plants or skid-mounted units to augment existing plant capacity.

Our range of technologies include:

Our technologies are used in large scale brick and mortar plants and in our range of packaged plants (water techno packages).

Biological processes form part of our water technology offering.
Municipal Treatment Plant, Water Techno Package (Packaged Plant), Industrial Water Treatment Plant
  • Municipal: Large- and small-scale plants and package plants for drinking water; treating and reusing water economically and sustainably.
  • Industrial: Specialised industrial process water and wastewater treatment. Includes AMD, sludge and effluent treatment, re-use and recovery.

Easily treat municipal water, sewage water and industrial process water and wastewater. Enquire now.

Our Water Technologies


Water clarification is used in the treatment of industrial effluent, municipal wastewater and municipal drinking waterto remove suspended solids and particulate matter, to improve setting and as pre-treatment to further purification processes.

Water clarification systems are either rectangular, where water flows from end to end, or circular, where flow occurs from the centre outward.

Get more information on clarification here.


Filtration may be used in the treatment of industrial effluent, process water, municipal wastewater and drinking water. It is also used as a pre-treatment step to membrane processes and desalination of seawater.

Oxidation & disinfection

Disinfection of water by physico-chemical is the destruction of disease-causing organisms. Processes such as ozonation and ultraviolet irradiation also aid in the destruction of biological contaminants that remain in the water after treatment.

These processes are used in potable water treatment, industrial effluent reclamation, municipal wastewater treatment, as well as ultra-pure water applications.

Membrane separation

In membrane separation, semi-permeable membranes allow certain molecules or ions to pass through by diffusion and, occasionally, by specialised "facilitated diffusion".

Get more information on membrane separation here.

Ion exchange

A cationic or anionic process in which ions are exchanged between the solution and an ion exchange resin. Ion exchange is reversible and resin can be regenerated for re-use. The process is widely used for water softening in industrial and residential applications.

Aerobic and anaerobic biological processes

These are naturally occurring processes harnessed to treat waste, produce biogas, provide heat and produce compost. These digesters are commonly used for sewage, municipal wastewateror industrialwastewater treatment.

Sludge treatment & handling

Sludge is a source of valuable by-products and agriculturally beneficial ingredients, such as phosphorus extracted from struvite. Managing the increasing sludge volumes generated by municipal and industrial water and wastewater treatment processes is a major environmental challenge worldwide. The benefit of treating sludge is the capacity to recover energy.

Evaporation & crystallisation

Thermal processes like evaporation and crystallisation are used in industrial applications, in water treatment involves the recovery of water from a brine or waste stream, or the production of potable or process water from seawater. Usually these processes are used in combination with other processes such as reverse osmosis to establish a Zero Liquid Effluent Discharge plant.

Membrane bioreactors

An effective process for treatment and reuse of industrial and municipal wastewater, Membrane Bioreactors (MBR) combines a membrane separation process such as microfiltration, ultrafiltration or reverse osmosis with a suspended growth bioreactor.

We have over 350 proprietary technologies covering everything from pre-treatment to sludge treatment and water reuse. Enquire today.
