Redesign of effluent treatment

Location: Saint-Auban (04)
Project phases: Feasibility studies
Study period: 6 months

Context of the project: Arkema has a biological station and a physico-chemical station in Saint-Auban. The biological plant treats Arkema’s industrial effluents and effluents from the city of Saint-Auban. The city will stop sending its effluents, making the biological station oversized and inadequate. The project therefore consists in migrating the treatment from the biological station to the physico-chemical station, which is obsolete and has been shut down for several years. The effluents discharged must comply with the new Ministerial Order and the BREFs

Studies :

  • Study and definition of the segregation of effluent flows:
    • Acidic flows without TSS or COD that only require pH adjustment
    • Flows loaded in TSS and/or COD
    • Fluxes loaded with adsorbable organic halogen and aromatic organochlorine
    • Neutral flow without any need for treatment
  • Pilot laboratory tests
    • Neutralization
    • Physico-chemical treatment
    • Adsorption on activated carbon
    • Ozone oxidation
  • Based on the results of laboratory tests:
    • Definition of the physico-chemical treatment process
    • Definition of the size of the structures
    • Audit of the existing station
    • Validation of existing recoverable equipment
    • Creation of new works
    • Definition of activated carbon filters
  • Implementation of PIDs, functional analysis, implementation plans
  • CAPEX, OPEX and planning

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
