Laboratory Testing

Ozone and AOP Application Services.

Oxidation services

Ozone is a solution for any oxidation application including resource recovery processes. Veolia provides full lifecycle services to develop the optimum oxidation solution for our clients.
 

The first challenge for any solution is feasibility. Feasibility studies by the Ozonia team define process solutions to meet your challenges.

  • Batch and semi-batch laboratory testing

  • Continuous laboratory testing

  • On-site pilot testing

  • Analytics

  • Expertise and innovation using the Veolia database

  • Literature research

Process Application Services

Partnering with clients for results

Ozone-based AOP laboratory testing provides results that our clients can count on to meet their goals.

  • Our services provide a technical-economical assessment for the optimum oxidation process mechanics including ozone dose, concentration, and process ratios

  • We evaluate the site-specific evolution of water parameters (COD, TOC, AOX, micropollutants CECs) to ensure the feasibility of our solutions

  • Ozone-based AOP combined with biological testing allows us to recommend a combined ozone-biological treatment process to minimize capital and operational costs

  • Pilot testing confirms laboratory testing to optimize full-scale installations and define continuous mode settings to manage:

    • Water matrix variations

    • Process guarantees

Success story:

From laboratory to full scale

Industrial wastewater COD and colour removal

01

Challenge

New regulations required stringent COD discharge concentrations. Process goal was to remove > 60% COD. Client required a bolt-on process to remove several items:

  • Color

  • COD

  • Hard COD compound

03

Results

Laboratory testing at the Ozonia ozone innovation center in Zürich used  to  define AOP process and equipment requirements. Two-stage AOP selected  to achieve an optimized 60% Color / COD reduction.

  • 1st stage: O3

  • 2nd stage: O3 / H2O2

Intelligent process design allows the most cost effective process combination to reduce capital and operational costs Hydroxyl radical reactions were required to break down the remaining refractory (hard to degrade) color compounds and COD.

02
