NHWSF
Since 1999, Ovive has operated in the world of wastewater treatment. During this time, we’ve developed a series of technologies to address the technical and regulatory changes that have taken place in the life of facilities.
In 20 years, Non-Hazardous Waste Storage Facilities (NHWSF) have shifted their focus from simply ‘making more space’ to becoming flow managers and renewable energy producers. This permanent technological innovation enables us to tackle the challenges of control leachates and odors, as well as treating and recovering biogas or cogeneration heat.
- Leachate treatment at over 100 non-hazardous waste storage facilities in France, by delivering or constructing a treatment facility.
- See our page about NHWSF leachates to learn more
Heat recovery unit by evaporation of the discharge, drying of sludges, biological pre-treatment
Heat recovery productsTreatment of the H2S by adsorption over media (Ovive FDS, Ovive KI, etc.) or biological treatment (Ovive BDS)
Re-injection of biogas into the GRDF network with our partner WAGA Energy
Treatment of the H2S in a lagoon by Ovive HF dosage
Eflox flare with a low methane rate, in order to better degas sites
Specific Cases
Leachate treatment and biogas recovery:
- Biogas boiler
- Biological pretreatment in a heated, aerated lagoon
- Leachate treatment using Membrane Bioreactor MBR+
