MIT ODOR CONTROL
With rising environmental standards and smarter monitoring systems, odor control is evolving. Technologies now integrate real-time sensors, AI-based dosing systems, and remote monitoring platforms to predict and prevent odor events before they occur.
Odor Control Technologies
- Chemical Treatment
- Liquid-phase dosing: Chemicals like iron salts or Bioxide are injected into the wastewater to prevent the formation of odorous gases.
- Oxidizing agents: Chlorine dioxide, hydrogen peroxide, and ozone neutralize odor-causing compounds.
- Biological Treatment
- Biofilters: Air containing odorous gases is passed through a bed of organic media (like compost or wood chips) where microbes digest the pollutants.
- Biotrickling filters: Combine biological degradation with continuous water trickling to maintain moisture and microbial activity.
- Physical & Mechanical Systems
- Activated Carbon Adsorption: Odorous gases are trapped on the surface of carbon granules.
- Mist Filtration: Removes moisture-laden odorous particles from air streams.
- Thermal Oxidation: Burns off odorous compounds at high temperatures, converting them into harmless gases.
- Scrubbing Systems
- Wet Scrubbers: Contaminated air is washed with a liquid (often chemically enhanced) that absorbs and reacts with the odorants.
- Packed Towers: Increase contact time between air and scrubbing liquid for higher efficiency.
