Séché Traitement des Eaux Industrielles (STEI) is the only point of contact you need to design, build, renovate and commission your facilities.
Our teams support you in managing your water cycle. They will work with you to design a solution tailored to suit your needs, whether that is building process water production facilities for your manufacturing processes and utilities or effluent and sludge treatment facilities.
A comprehensive range of complementary technical solutions
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...)
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 defense 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.
