Process water treatment

We help industrial businesses take control of the quality and cost of water used to supply their production-critical processes.

The water supply to processes and utilities is the largest water-related cost at an industrial site. This water is used in cooling systems, boilers, processes and sometimes in the product itself. Flexibility and precision in managing this resource is essential as water quality and quantity requirements can be challenging and they vary from one application and site to another.


SUEZ operates and maintains a broad range of equipment for treating process water across all industries – from food and beverage through to oil refining and power generation.


Our in-house expertise and strategic partnerships mean we are able to provide all the water-related services you will require, from raw water abstraction through to polished water delivery.


With our help, you can:

  • Ensure you always meet your site’s process water quality and quantity requirements.
  • Employ the latest membrane, softening and filtration technologies.
  • Tailor your water treatment systems to cater cost-effectively for the specific needs of your site.
Tailoring treatment to your exact requirements

The level of treatment that needs to be applied typically depends on the degree of water purification a process requires. For example, a water feed to a cooling tower would generally require far less treatment than a water supply to a high-power boiler or a printed circuit board manufacturer. A cooling tower may only require solids removal and biocide dosing to reduce biological activity. Process water for a printed circuit board manufacturer, however, may need to be completely free from solids and dissolved salts, as it could come in to contact with and potentially affect the finished product.


Other considerations may affect the quality of process water. Examples at the point of abstraction include the seasonable variability of river water quality and borehole integrity. Your site’s requirements for water may also increase, which can result in the water treatment plant operating above its original design scope. Or the plant could require more maintenance due to ageing.


We offer a range of process water treatment solutions that will be tailored to your application and site. These range from chemical dosing through to settlement and filtration, and to more advanced treatment such as membrane separation, ion exchange or electrodeionisation.


With decades of industry experience, our deep understanding of industrial water processes and systems ensures your plant is operated and maintained for optimum performance.

Ensuring production continuity

Whether the water feeds the product manufacturing process or is used for steam production, cooling or washing, any failure in a process water production unit could have an immediate impact on your industrial’s site production.


Ensuring continuity of production involves regular maintenance to your water production facilities. Our dual builder-operator expertise is an undeniable advantage in ensuring the sustainability of your water treatment facilities. We design and deliver maintenance plans scaled to your production line, with key performance indicators (KPIs) to measure the results guaranteed under our contract.


We can swiftly deploy mobile water treatment units in case of a fault or failure in your water production system, or a sudden deterioration in your water resource. Our mobile units can guarantee the quality and quantity of water required for your facility.


Mobile units also play a vital role in planned maintenance and servicing operations, when upgrading your existing equipment, starting up new installations, or dealing with variations in production levels.
