Studies :

• Project Quality Plan
• assessments (material, heat, utility, power)
• Implementation of PFDs (process flow diagram) and then PIDs (piping and instrumentation diagram)
• Sizing of new equipment and storage capacities
• Elaboration of project lists (equipment, motors, piping, valves, cables)
• Implementation of the whole project in the existing workshop
• Preliminary security analysis
• Drafting of new functional analyses
• Drafting of preliminary technical specifications for preliminary design consultation: equipment and works contracts (civil engineering, structure and framework, piping, electricity / instrumentation / automation, “centralized dust collection” package)
• CAPEX and implementation planning

Audit, improvement, reliability and debottlenecking of the wastewater treatment plant

Location : Fos-sur-Mer (13)
Project phases: Feasibility studies
Study period: 2 months

Emdelen Mission:

• Installation audit
  • Analysis of the current operation (flow rate, pH, COD, MeS, nitrogen, O2, Fe content)
  • Loads applied already close to design values
  • Average nitrogen concentration too high
  • TSS content too high for aerobic treatment
  • Carbon deficit
  • Excessive iron content for ultra-filtration membranes
  • Anaerobic buffer tank
  • Limiting anoxic basin volume for the average nitrogen flow
  • Sludge age too old
• Based on the conclusions of the audit (confirmed by our laboratory tests), proposals to Evere for the following modifications:
  • Implementation of a redox control in the buffer tank
  • Control of the hydro-ejector of the buffer basin with redox
  • Installation of an aeration of the anoxic basin controlled by a redox probe
  • Separation of biomass (to protect the membranes from ultra filtration) by the installation of a clarifier and tanks for re-aeration, degassing and flocculation upstream
  • Recycling of clarifying sludge to anoxic basin
  • Finishing treatment of the hard COD on activated carbon filter
• Realization of PIDs, 3D model, functional analysis, equipment specifications, layout plans and civil engineering guide plans of the clarifier
• Recommendations on operating parameters (redox, oxygen in aeration, methanol dosage, sludge recycling rate, pH)
• CAPEX, OPEX and planning

Turnkey project for the construction of a skid for the treatment (COD: Determination of Chemical Oxygen Demand) of radioactive effluents from the dismantling of a workshop at a nuclear site.

Location: Dessel, Belgium
Project phases: Study, realization, assembly and start-up
Project duration: 36 months

Project context: Turnkey project in partnership with a local company for the construction of a unit to treat organic matter contained in radioactive effluents.

Studies for the treatment of radioactive effluents :

• From the treatment process defined upstream: assessments, sizing of equipment and drafting of technical specifications of equipment
• 3D design and implementation of the skid

Realization and start-up :

• Equipment purchases
• Follow-up of manufacturing at equipment suppliers
• Quality Assurance file
• FAT (Factory Acceptance Test) and SAT (Site Acceptance Test) of the complete skid after assembly
• Assistance with start-up and performance testing

Completion of the industrial transfer of a nanosphere and polymer microsphere manufacturing unit.

Location : Meyzieu, Rhône FRANCE
Project phases : Detailed design and implementation (studies and monitoring of the transfer)
Project duration : 3-month detailed design and 18-month implementation

Within the MERCK group, the ESTAPOR division has been designing and manufacturing nanospheres and microspheres of polymers, magnetic or not, since 1993.

MERCK wanted to regroup ESTAPOR’s premises, initially in Pithiviers, on its Meyzieu site. For this purpose, MERCK had decided to rely on the services of an industrial engineering team to confirm the preliminary design studies and manage the complete transfer, from the shutdown of the units and the management of the stocks before transfer to the complete reassembly on the host site. The transfer concerned the two ESTAPOR businesses: laboratory (clean rooms) and production (grey rooms). The reception site was completely dismantled since the previous activity was still in place on the floors.

Total amount of the project :

Range A < €10 million
Range B: between €10 and €20 million
Range C: between €20 and €50 million
Range D > €50 million
