Drinking Water

Drinking water from Veolia Water Technologies South Africa conforms to the highest scientific standards. Drawing on a portfolio of over 350 proprietary technologies, we’re able to treat feed water from boreholes; rivers and lakes; the sea; and even wastewater into high-quality potable water.

Our solutions for drinking water can be supplied through large-scale permanent plants for use by towns and cities, or in containerised plug-and-play package plants that provide flexible, portable and scalable treatment solutions for remote settlements and camps, and temporary applications.

Our treatment technologies for drinking water include:

We implement these technologies as part of a tailored solution as determined by the volume of your drinking water requirements and feed water specifications.

Drinking Water from Surface Water

The supply of drinking water to households and businesses starts with the abstraction of intake water and its pretreatment. Treatment will depend on the nature of surface water including its turbidity (suspended mineral or organic matter). Non-turbid water can be sent to direct filtration treatment systems, while turbid water needs to be clarified and filtered / polished.

  1. Turbid water is sent for clarification. Coagulants are added, gathering suspended solids, colloidal matter and some dissolved matter into flocs that can then be removed by settling or flotation.
  2. Non-turbid water is easier and cheaper to treat, as it requires only filtration before disinfection.

Both non-turbid water and pre-treated turbid water need to be filtered before final disinfection and distribution. Filtration, through sand filters, adsorbant media (activated carbon) and membranes (ultrafiltration, nanofiltration), removes organic matter and micro-pollutants and provides a barrier against bacteria and virus.
Polishing, sand filtration, activated carbon filtration and ultrafiltration are the technologies used in the filtration / polishing of feed water downstream of clarification.
Feeds downstream of treatment systems of both turbid and non-turbid water need final disinfection following filtration. Disinfection agents (chlorine), ozone and UV are used to remove viruses and bacteria. This water is then ready to be stored in water tanks.
This water is now ready to be used and safe for human consumption!

Drinking Water from Groundwater

Water abstracted from the ground via deep wells has slightly different treatment requirements than water abstracted from a river to achieve drinking water standards, but can still be roughly divided into turbid and non-turbid water streams.
Non-turbid water can be treated through aeration / stripping. The oxygen injected into the water eliminates carbon dioxide and iron.
Turbid water needs to be treated for the removal of natural organic matter as well as micro-pollutants, and this is achieved through filtration and polishing. Sand filtration, adsorbant media (activated carbon) and membranes are used, removing bacteria and viruses for sanitary security.
Because groundwater may carry pollutants generated by agricultural or industrial activities, various specific treatments need to be incorporated into the overall treatment system. These pollutants include arsenic, pesticides, micro-pollutants, nitrates, iron, manganese and even radioactive compounds. Water softening may also be utilised.
Before the water reaches drinking water standards, it needs a final disinfection treatment. Treatment such as chlorination, UV and ozonation is used to remove viruses and bacteria. Water is then transferred to tanks.
This water is now ready to be used and safe for human consumption!

Drinking Water from Desalination

In many cases, desalination technology remains the only option for producing potable drinking water. Veolia offers both thermal and membrane separations to desalinate both seawater and, in arid inland areas, brackish water.

  1. Beachwells are an innovative water intake system for seawater that provide stable, reliable high-quality feed water that is ideal for maintaining the durability and performance of downstream membranes. Beachwells make use of natural filtration through sand bank layers.
  2. The primary method in Southern Africa for producing drinking water from desalination is reverse osmosis (RO) membrane filtration. Here, water is forced through a semi-permeable osmotic membrane at high pressure and reaches an osmotic equilibrium, with salts retained on the seawater feed side. It is suitable for high and low salinity concentrations.
  3. Downstream of the RO treatment process, water needs to undergo remineralisation in order to achieve potable drinking water standards and to avoid corrosion of the pipe networks. Carbonate media filters are used, with injection of lime and CO2.
