Wastewater treatment

Helping companies achieve and sustain the highest standards across the entire industrial water cycle.

Ensuring that wastewater is managed, treated and safely discharged within regulatory standards is a critical element in many industrial processes. Failure at any stage of the effluent management process can compromise operational efficiency, site safety and the local environment. Breach of discharge consents can lead to prosecution or plant closure.

With extensive experience in industrial water management, SUEZ Water UK provides a fully comprehensive range of troubleshooting, consultancy, treatment, design, construction, operations, maintenance and optimisation services to businesses of all sizes, in all sectors.

We help companies achieve and sustain the highest standards across the entire industrial water cycle – even returning water to the environment cleaner than it was extracted. With our help, you can:

  • Control your site’s effluent discharge and comply with standards and regulations
  • Employ the latest, efficient aerobic and anaerobic biological treatment technology
  • Ensure your systems are running to their optimal level

The right chemistry

The details matter in effluent treatment performance, and those details include not only the choice, composition and quality of the chemical and biological products used but also how they are used.

We formulate and supply a wide range of standard and bespoke treatment products in our specialist manufacturing facilities and advise how to best use these products for optimum performance, allowing us to meet the unique requirements of each customer and each site we serve.


As part of our initial evaluation, our team of effluent consultants can carry out field jar tests on your site. This can identify if the chemistry in your system is right which will help ensure optimum performance.

Our product range encompasses all aspects of effluent treatment. It includes chelating agents, coagulants and flocculants optimised to suit specific site requirements; products for biological treatment; pH control and antifoaming products; high performance polymers for sludge dewatering; and a full range of odour control materials.
