SANOFI – New treatment plant

New effluent treatment plant for the vaccines business

Location: Neuville-sur- Saône (69)
Project Phases: Detailed Preliminary Project Study
Study period: 2 months

Context of the project: following the conversion of the Neuville Sur Saône chemical site with the establishment of a vaccines business (Sanofi Pasteur) and the gradual closure of the chemistry business, the existing effluent treatment facilities were obsolete. The construction of a new effluent treatment plant dedicated to the vaccines business was necessary. This station must be scalable to keep pace with the growth of the vaccines business.

Pollutant to be treated: COD, BOD5, TSS, Global Nitrogen, Total Phosphorus

Emdelen Mission :

  • Flow balance, material balance and definition of the treatment chain
    • Water channel (biological) including the following steps:
      • Homogenization of effluents in buffer tanks
      • Neutralization of effluents
      • Biological cultures on mobile media with syncopation to alternate nitrification and denitrification sequences
      • Separation of the bio-mass by pressurized float
      • Coagulation of effluents leaving the floater
      • Filtration of effluents on rotating screens
      • Counting and discharge of effluents in the natural environment
    • Sludge filter comprising the following steps:
      • Storage of sludge coming out of the floater
      • Sludge conditioning
      • Sludge dewatering on filter presses
    • Definition and preparation of reagents: lime milk, polymer, ferric chloride
    • Treatment of tank vents on activated carbon filtration
  • Realization of PID schematics
  • Writing of the Functional Analysis, definition of the PLC inputs/outputs and the automation architecture
  • Single-wire electrical diagram and power balance
  • Implementation of implementation plans
  • Allocation of the project
  • Specifications and consultation of equipment batches
  • Specification and consultation of work packages
  • Analysis and comparison of offers
  • Drafting of control documents and operation of the station
  • Listing of laboratory equipment required for operation
  • Planning, Capex (€2.5m) and Opex
