Wastewater treatment

Photo de silo de traitement des effluents Corelec

Industry by nature

To limit pollution generated by surface treatment activities, CORELEC Équipements designs and manufactures air and water decontamination processes that respect the environment and comply with current regulations.

Initially applied in the field of surface treatment processes, we successfully expanded our solutions to all industrial activities (aerospace, oil & gas, chemistry, nuclear, construction, automotive, luxury, industry, healthcare, waste recycling etc.).

The environment department also designs and manufactures equipment for the treatment of vapours (waste gases).

Laboratoire chez Corelec

An in-house laboratory to devise the best solution

Your pollution control projects are modelled in our in-house laboratory, either on a laboratory scale or on an industrial scale using fixed and 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

Our solutions and processes for industrial liquid waste

Each proposed solution and developed process responds specifically to our customers’ needs, always considering the best available techniques.
We also anticipate 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 CONCENTRATION

These thermal processes allow the separation of water and dissolved salts for the recycling of treated waste.
We offer 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 vapor compression system
  • 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.

PHYSICO-CHEMICAL TREATMENT

Physico-chemical processes are implemented when the aim is the discharge of wastewater to the outlet.

Our different processes:

  • Storage of raw waste
  • Physico-chemical treatment
  • Sludge conditioning (decantation, thickening, pressure filtration)
  • Finishing treatments (granular activated carbon (G.A.C.), selective ion-exchange resins, etc.)
  • Coagulation, neutralization, flocculation, filtration
  • Decantation, flotation
  • Sludge dewatering
  • Specific treatments: dechromatation, decyanidation

Our specific equipment:

  • Measurement and regulation
  • Pumping and transfer
  • Storage
  • Dosing
  • Stirrer

ION-EXCHANGE AND RESIN ABSORPTION RESINS

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

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 filtration processes on membranes (microfiltration, ultrafiltration or reverse osmosis)

Our different processes:

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

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

Facilitating the full recycling of treated waste, this solution combines several technologies, in particular:

  • Demineralized water production
  • Conventional physico-chemical conditioning or 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 is also specialised in the design, construction and commissioning of tailor-made solutions, allowing the treatment of these waste gases complying 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 SCRUBBER

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