Industry by nature

In order to limit pollution generated by surface treatment processes, CORELEC Équipements designs and manufactures air and water decontamination processes that respect the environment and conform with current regulations. To this end, our Environment department offers a range of complete solutions for the treatment of industrial waste.

Initially applied to surface treatment processes, by recruiting the right specialists, we have been able to successfully extend our solutions to all industrial activities (Aerospace, Oil & Gas, Chemicals, Nuclear, Construction, Automotive, Luxury, Manufacturing, etc.).

Drawing on decades of experience and CORELEC Équipements’ numerous fields of business expertise, the Environment department also provides services for the sizing, design and manufacture of equipment for the treatment of vapours (waste gases).

Laboratoire chez Corelec

A comprehensive laboratory to devise the best solution

We model your decontamination projects in our in-house laboratory, either at the “lab” scale or on an industrial scale (fixed or mobile pilots).

We analyse your needs and choose the best solution from the available options:

  • Physicochemical tests: coagulation, neutralization, flocculation, filtration
  • Filtration technics (gravity, vacuum)
  • Vacuum evaporation and condensation (heat pump, mechanical steam compressor)
  • Ion-exchange resins
  • Activated carbon adsorption
  • Advanced Oxidation Technology

Therefore, each solution we propose and each process we develop will respond specifically to your problem, always considering the relevant Best Available Techniques.

  • Service/maintenance and after-sales technicians

Our state-of-the-art manufacturing facilities are grouped together on a single 10,000 m² site and cover all our areas of expertise.

Our solutions and processes for industrial liquid waste

To guarantee the best treatment solution, the processes offered by CORELEC Environment always incorporate the Best Available Techniques. We are also anticipating the tightening of rejection standards around substance-related issues (REACH), in order to offer the most sustainable solutions and processes and guarantee the safety of your investment.

VACUUM EVAPORATION AND CONDENSATION

Vacuum evaporation and condensation are thermal processes allowing the separation of water and dissolved salts for the recycling of treated waste. CORELEC Équipements offers a range of solutions covering all your needs, from 0.15 m³ / 24h up to 240 m³ / 24h.

Our different processes:

  • High vacuum and low temperature: heat pump system
  • Partial vacuum and high temperature: mechanical steam compression
  • Hot / cold water system
  • Concentrate system to extract dry matter
  • Any additional system for special designs (technological coupling: multi-stage evaporation)

Reduction in the volume of waste:

If the objective is to reduce the volume of waste produced, evaporation processes can be applied directly to the waste. The use of evaporators can also be extended to the shedding of certain pollution flows on conventional structures where treatment may compromise overall performance or where the substances discharged are not compatible with current standards.

PHYSICOCHEMICAL TREATMENT

Physicochemical processes are implemented when the aim is the discharge of wastewater from an outlet.

Our different processes:

  • Storage of raw waste
  • Physicochemical treatment
  • Sludge conditioning (settling, thickening, pressure filtration)
  • Finishing treatments (granular activated carbon (GAC), selective ion-exchange resins, etc.)
  • Coagulation, neutralization, flocculation, filtration
  • Settling, flotation
  • Sludge dewatering
  • Specific treatments: dechromatation, decyanidation

Our specific equipment:

  • Measures and regulations
  • Pumping and transfers
  • Storage
  • Dosage
  • Stirrers
  • Etc.

ION-EXCHANGE AND ABSORPTION RESINS

Filtering of ion-exchange resins.
Pre- and/or post-treatment by activated carbon filtering.

Our different processes:

  • For demineralized water production
  • For total or partial recycling applications
  • As an initial treatment, whether for protection or finishing

MEMBRANE TECHNOLOGIES

Our tangential membrane filtration processes (microfiltration, ultrafiltration or reverse osmosis)

Our different processes:

  • For the production of process water
  • For the treatment of waste

UV TECHNOLOGY, ADVANCED OXIDATION

For the treatment of waste and complex molecules.


Our different processes:

  • Ozonation
    Photochemical radiation (catalysed or non-catalysed)

ZERO LIQUID DISCHARGE STATION ON SITE

In order to support the full recycling of treated waste, this solution combines several steps, in particular:

  • Demineralized water production
  • Conventional physicochemical conditioning or conditioning using membrane technology
  • Finishing using vacuum evaporation and condensation
  • Post-treatment of distillate (according to the desired quality of recycled water)
  • Final reduction of waste through a concentrator

Our solutions and processes for industrial waste gases

Besides generating potential contaminants in the form of liquid waste, the majority of industrial surface treatment processes also generate gas emissions.

Our Environment department specialises in the design, construction and commissioning of tailor-made solutions allowing the treatment of these waste gases in compliance with current environmental standards and emission limits.

VENTILATION

  • Ventilation of workshops and on-site capture of pollution sources
  • Protection of employees in contact with hazardous substances or substances regulated by specific legislation

GAS SCRUBBING

  • Treatment of gas emissions through liquid/gas absorption for all types of acidic and basic gases
  • Treatment of odours by physicochemical processes or activated carbon adsorption
