Sectors of application

Industry / Facility operators in river or marine environment / Environmental agencies / Water engineering / Environmental consultants

Your challenges

  • Optimizing the chemical treatments (e.g. biocidal treatments) in place in order to conciliate  "industrial performance", "economic viability" and "environmental and health acceptability”
  • Characterize chemical releases, including unknown transformation by-products, and assess their environmental fate
  • Understanding the physico-chemical and biological phenomena involved in industrial processes and in the environment
  • Evaluate the environmental impact of new technologies (new chemicals or processes)
  • Identify room for action and rationalize technological choices, in order to guarantee compliance with environmental regulations

Our strengths

  • Complete solutions, ranging from opportunity study (technical and economical feasibility), experimentation and expertise. A gradual response, adapted to the needs and challenges.
  • Skills valued by the scientific community (publications in specialized journals).
  • A multidisciplinary team: coupling chemistry and ecotoxicology approaches for the identification of contaminants at risk for the ecosystems (Effect-Directed Analysis approaches, Mass Balance Analysis, etc.).

Our offer

  • Experiments in laboratory, in semi-industrial testing facility and in natural field environment: process optimization (biocidal and anti-scale treatments), understanding of phenomena, evaluation of the environmental fate of chemical substances at environmentally relevant concentrations
  • Development of analytical strategies and protocols, allowing to characterize chemical contaminants (including their unknown compounds) in different matrices:
    • Chemical substances: disinfection by-products (trihalomethanes, haloacetic acids, etc.), organohalogen compounds (e.g. AOX, POX, EOX, AOCl, AOBr, AOI), amines, nitrosamines, oxidants (monochloramine, chlorine, ORT), etc.
    • Matrices: natural water (fresh and saline), industrial effluents, sediments, soils, suspended solids, biota, etc.
  • Consulting and expertise in analytical sciences and environmental chemistry (e.g. chlorination and monochloramination by-products)
  • Writing of technical and scientific reports, based on literature review and/or experiments
  • For rent : laboratories, analytical equipment (incl. training)
