Pilot for the treatment of industrial wastewater containing volatile compounds, for both pedagogy and research and development. It is a flexible equipment that allows feasibility studies on different types of contaminated water. It is composed of :
- 10 l capacity polyethylene feed tank with removable lid
- Total drain valve at the bottom of the tank
- Raw water supply valve
- Variable flow centrifugal feed pump
- Supply pipe at the top of the PVC column
- Control valve and flowmeter on filter supply
- A filtration column on the air stripping bench and modifications on the bench to accept this filtration column
- Gas chromatography and mass spectrometry
- Ion chromatography
- Atomic absorption spectrometry with flame
- Zetameter
- Infrared spectroscopy
- Total organic carbon analyzer
- High performance liquid chromatography
- UV-Visible spectrophotometer
- Solid phase extraction equipment for hydrocarbons
- Basic analytical equipment
- Oil & grease analyzer
- Activated carbon adsorption column
- Column for aeration tests
- Respirometer
This pilot laboratory is a powerful, mobile and flexible infrastructure for testing and demonstrating, at low cost, and directly in industrial environments or on degraded sites, new remediation and decontamination processes before their implementation on a real scale. . The laboratory team works to develop technologies for the treatment, decontamination and recovery of various matrices polluted by metals and other types of pollutants. The development of processes contributing to sustainable development in the field of environmental technologies is a priority research area of the INRS. The laboratory has a multifunctional mobile pilot plant to operate various types of physical, chemical and biological processes for the treatment of soils, hazardous wastes, gases, as well as industrial residues and effluents directly on contaminated sites.
• Ionic Chromatograph
• Gas and liquid chromatographs
• Mass spectrometers
• Level 2 Laboratory for Bacteria
The AS+ unit is composed of activated sludge (AS) treatment and a membrane process. Several configurations are possible:
- Activated sludge "classic"
- Use of media with or without activated sludge
- RBS (Sequential Biological Reactor)
- BRM (Membrane Bioreactor)
- FPB (Low Sludge Production)
This innovative unit consists of 4 platforms. The objective is the elimination of dissolved pollution by the following processes:
- Pre-treatment by ballast settling (Actiflo-MiniTM)
- Ozonation or advanced oxidation (ozone - UV)
- Adsorption / biodegradation on activated carbon powder (CAP)
- 4 parallel streams of biomembranes under pressure
- 2 parallel dies of submerged biomembranes
This pilot unit allows biofiltration on floating media (BiostyrTM) coupled to an MBBR process including feed pump, biofiltration column and treated water storage tanks and sludge. The BiostyrTM unit is used in secondary treatment at a flow rate of 0.35 m3 / h (filtration rate 5 m / h).
This unit groups conventional processes for the treatment of drinking water:
- Pumping system and pretreatment
- Conventional flocculation and settling
- Weighted decantation (ActifloTM unit)
- Granular filtration, conventional or direct (4 filtration columns)
- Ozonation
This mobile pilot unit made the weighted decantation (ActifloTM) including a sieve, a flocculation basin, three mechanical mixers, a static decanter and a dosing system (coagulant, soda, polymer). ActifloTM can be used in primary or tertiary treatment. Its treatment capacity is 2 to 6 m3 / h (speed of 40 to 120 m / h).
Nine stations that can be installed in a river, sewer or stormwater system or in a wastewater treatment plant. They include a metal enclosure, with a computer with software for monitoring and data processing (connected to the Internet), and sensors of different brands (pH, conductivity, turbidity, UV-Vis spectrometer, ammonium and nitrate, dissolved oxygen), and various control or maintenance elements (heat control, electric valve for air cleaning, etc.). The processing of data quality and storage of data in an organized database to also contain metadata (data on data) are important features of this development by the Canada Research Chair in Quality Modeling. water, which was marketed by the company Primodal (RSM-30).
