Environmental performance
For more than 15 years, the Ortec Industrie Fos-sur-Mer agency has developed recognized expertise in water treatment and sludge dewatering, further strengthening Ortec Industrie’s capabilities in: :
- Hydrocarbon streamsÂ
- Contaminated streamsÂ
- Hazardous wasteÂ
With their mobile units, our experts operate throughout France, providing services directly at customer sites, industrial facilities, wastewater treatment plants, and local authority sites.Â
The purpose of sludge dewatering is to reduce the volume of liquid sludge.Â
This volume reduction helps lower treatment and transportation costs. It also supports waste recovery (sludge and aqueous residues).Â

ASSESSMENT AND ANALYSIS
Assessment and Consulting
Our team is available to support you throughout your project and answer any questions you may have about the different stages of the worksite.
Analysis / Diagnosis / Sizing
To determine the most suitable dewatering or treatment solution, samples must first be collected.Â
These samples are used to:
- Carry out analyses, including flash point and pollutant testingÂ
- Verify coagulation and flocculation performanceÂ
- Estimate the volume reduction achieved through dewateringÂ
- Determine the recommended treatment methodÂ
- Identify suitable disposal or recovery channelsÂ
Project proposal
Our teams then present a solution tailored to your needs and remain available to discuss it with you.Â

Water Treatment
The objective is to remove contaminants from the water so that it can be reused in production circuits.
This is achieved through the following processes:Â
- Suspended solids treatmentÂ
- Hydrocarbon separationÂ
- Dissolved pollutant treatmentÂ
- StrippingÂ
- FiltrationÂ
Waste management
Collection Containers
Our team provides personalized support, adapting the setup and management of collection containers to the specific requirements of each site.
Transportation and Tracking
We operate multiple types of equipment to meet each request efficiently, including ADR- and ATEX-compliant equipment.Â
