Comprehensive services to operate and maintain your water treatment facilities

To operate and maintain facilities, Séché Traitement des Eaux Industrielles (STEI) leverages the expertise it has acquired over 25 years working in industry for a great many clients.

We work with you to optimize the operation and maintenance of all your facilities, whether that is water production plants (process water, ultra pure water, heat transfer water…) or effluent and sludge treatment plants.

 

Multi-process specialists

Our highly competent engineers and technicians are proficient in the processes and technologies that span the entire water cycle:

  • Water purification (filtration, softening, ultra filtration, reverse osmosis, demineralization…)
  • Physicochemical processes (coagulation, flocculation, redox, neutralization, oil separation…)
  • Biological treatment (aerobic, anaerobic)
  • Liquid-solid separation (sedimentation, lamellar sedimentation, floatation, filtration…)
  • Membrane treatments
  • Polishing (adsorption using activated carbon, filtration, disinfection…)
  • Evapo-concentration
  • Dehydration of sludge (centrifugation, filtration using mechanical supports…)

Performance-based contracts

Our specialized technicians enable us to guarantee the continually high quality of the water we treat. We manage every level of maintenance (from 1 to 5) and put in place on-call rotas so we can intervene 24/7 if necessary. Our processes are designed to reduce discharge and ensure it is fully compliant with environmental standards. 

Recycling and reusing treated wastewater

Process water is an essential component in manufacturing and transformation processes. By reusing wastewater, you reduce:

  • your environmental footprint and help preserve a precious resource at a time when the climate is warming and conflicting demands are on the rise
  • industrial risks related to your water supply
  • operating expenses by minimizing consumption

We support you all throughout your project by auditing your existing facilities, drawing up a reuse plan, conducting feasibility studies, building or commissioning facilities or providing maintenance of technical assistance.

Clients from across the entire economy, including the agrifood, chemical, petrochemical, metallurgy, transportation, electronics and defence industries, place their trust in us.

Our Group has been providing environmental services for many decades. We have developed a clear understanding of the main constraints as all our own facilities are listed under French environment protection regulations (ICPE) and sometimes Seveso. Managing safety and hazards form an integral part of our work, as does preserving natural environments and creating circular economy loops.

Why outsource?

Audit and solution design

We audit the facility under operation, sometimes even conducting a full audit of the water cycle, depending on your needs. Our specialist Technical Department and R&D teams trial solutions in the lab or at industrial pilot sites if necessary.

Contractual framework

We work closely with our clients to draw up a contract tailored to suit each facility.

Operation/Maintenance

We provide a range of services and can also offer 24/7 on-call assistance:

  • Oversight and management of the facility
  • Analytic tracking and settings
  • Provision of reagents
  • By-product management
  • Technical maintenance
  • Reporting, etc.

Continuous improvement

All throughout the contract we strive to achieve continuous improvement in operating the facility, optimizing costs and recovery channels for sludges, effluent and water. Our teams can help you develop and implement a progress plan, and fine tune it wherever necessary.
