Odour Control by Photoionisation

  • An exciting “new” technology in odour control.
  • New to North America
  • Successfully used for over 10 years
  • Based on the application of UV light and a catalyst.
  • Mimics natural reactions that take place in the upper atmosphere
  • Interaction of air and UV light from the sun.

Principles:

  • Odourous air exposed to intense UV light.
  • UV creates free radicals, (O- 2, OH-, O3, etc.)
  • Immediate oxidation of the odour-causing compounds begins.
  • Then air passes to a catalyst. - remaining odourous compounds are adsorbed.
  • Broken down by the constant flow of free radicals in the air from the UV section.
  • Catalyst acts as both a catalyst and “buffer”.

Advantages: 

  • SMALL FOOTPRINT CAN HANDLE HIGH CONCENTRATIONS – 100’s of ppm of H2S
  • HANDLES SPIKES EASILY
  • WIDE TEMPERATURE RANGE (-30 TO 70 deg C)
  • LOW MAINTENANCE (0.5 days per year)
  • NO WATER OR CHEMICALS
  • STABLE AND ROBUST
  • ON or OFF – IMMEDIATELY STARTS WORKING
  • LOW ENERGY

300 CFM PILOT PLANT AVAILABLE

Odour Control by Corona Discharge

  • Treats odourous air within a room or space.
  • Air is re-circulated.
  • Long track record - indoor air controlling yeasts, moulds, and odours.

Operation:

  • Air drawn into the unit and passes over a low-voltage corona discharge.
  • Free radicals, mostly "active oxygen" and other ions (activated 02 OH etc.) are created.
  • Immediate oxidation of odour-causing compounds.
  • Strict voltage control - minimizes ozone generation.
  • Meets EU standards for indoor air quality.
  • Air returned to the room.
  • Free radicals break down odour-causing compounds, moulds and germs in situ.

Advantages:

  • SMALL FOOTPRINT
  • LOW CAPEX / OPEX
  • MINIMAL MAINTENANCE
  • REDUCES ODOUR IN SITU IN A ROOM
  • PROVIDES SAFE WORKING ENVIRONMENT
  • FEW AIR CHANGES PER HOUR
  • ENERGY SAVINGS
  • NO WATER OR CHEMICALS REQUIRED
  • TURN ON ONLY WHEN ROOM OCCUPIED
  • NO DUCTING REQUIRED

Successful Applications:

  • Water and wastewater treatment plants
  • Food processing facilities
  • Composting and organic recycling facilities
  • Fertilizer plants
  • Rendering plants
  • Pulp and paper industries
  • Surface coating operations (lacquering, spray painting, printing)
  • BTEX and solvent removal operations
  • Foundries
  • Numerous other municipal and industrial applications

Chemical Scrubbing

Spray nozzles, placed at the top of each cell of the scrubber, produce a mist of droplets to create an exchange surface between the liquid and the pollutants. These droplets meet the gaseous pollutant, thereby creating the liquid/gas interface.

When pollutants pass against the current with the aqueous scrubbing solution, they are transferred from the gas phase to the liquid phase where they can be neutralized (acid-base or redox chemical reaction) by the reagent injection (soda, bleach, sulphuric acid, etc.).

Once the pollutants are dissolved, they are degraded and neutralized in the scrubbing liquid by chemical reagents. The liquid is then periodically deconcentrated then sent to the water treatment station.

Advantages

  • Flows up to 130,000 m3/h
    • efficiency greater than 99%
  • Constructed from PPH or HDPE
    • suitable for aggressive and corrosive compounds
  • Low maintenance requirements
    • reliable and fully automated operation
  • Customizable
    • sizes, materials, orientations etc.
  • Options
    • lined pumps, sloping bottom, finishing separator, etc.

Carbon Absorption

Activated Carbon by the adsorption process is able, due to its microporous structure, to trap harmful VOC-type molecules (Volatile Organic Compounds) or corrosive and odorous molecules present in wastewater treatment plants (NH3, H2S, etc.).

In order to increase the adsorption efficiency of pollutants, Activated Carbon may be impregnated with KOH or H2SO4 depending on the type of gas to be treated.

>Treatment with Activated Carbon is used in particular in processes within the chemical, petrochemical, food and pharmaceutical industries, and also in water treatment facilities (pumping stations, buffer/storm basins, sludge storage and processing).

Advantages

  • Flows up to 10,000 m3/h
    • efficiency greater than 99%
  • Thermoplastic or steel construction
    • suitable for aggressive and corrosive compounds
  • Customizable
    • size, regenerative adsorbant materials, etc.
  • Low maintenance requirements
    • excluding replacing activated carbon

Biofiltration

The operating principle of a biofilter consists in forcing the passage of a gas to be treated through a biomass medium, whose composition varies according to the pollutants to treat.

The purifying micro-organisms settle down the biomass, that is kept at optimal moisture level for their development.

Advantages

  • Several biomass media options
    • according to the effluent to be treated
  • Construction that is corrosian-resistant
    • plastic, concrete, wood, etc.
  • Customizable
    • size, materials, covering
  • Low operating costs
    • no reagent
