CONTINUOUS EMISSION MONITORING SYSTEMS (CEMS) : LANDFILL
INTRODUCTION
  • Landfill gas often containing 50'60% methane, is generated on waste disposal sites receiving organic waste.
  • Regulation requires that this gas is managed in order to reduce emissions, but very few suggestions exist as to how management activities are monitored, what should be set up to ensure this management and how criteria should be developed for when monitoring activities are terminated.
  • Methane emission monitoring procedures are suggested, based on a robust method for measuring total leakage from the site; additionally, quantitative measures, to determine the efficiency of the performed emission mitigation, are defined.
  • The tracer gas dispersion measuring technique is suggested as the core emission measurement methodology in monitoring plans for methane emissions from landfills and a guideline for best practice measurement performance is presented. A minimum methane mitigation efficiency of 80% is suggested. but doing onsite has been impractical.
AWAKENING CALL ONLY WHEN FIRE STRUCK THE LANDFILL
Landfill either with natural Phenomena can catch fire or with a purpose to clear the space for additional waste. The Fire is required to be avoided and thereby countering mass scale SMOG that is generated. Smoke and other atmospheric pollutants combined with fog generates unhealthy & irritating SMOG. To defuse and neutralize the fire is not only expensive and strenuous affair but the Smog impacts respiratory system.
RIGHT MONITORING AT RIGHT PLACE
  • Methane (CH4) plays a critical role in the radiation balance and chemistry of the atmosphere.
  • Measuring methane emissions directly from landfills and developing a better understanding of how environmental variables control these emissions are essential for reducing the uncertainty in reported greenhouse gas emissions.
  • AUM provides a continuous, automatic, direct measurement of spatially averaged gas flux over a large upwind area with no human interference.
  • AUM monitors CH4, C2H2, CO2, H2O at ppb level precision in total methane concentration.
  • Photonic technology is an excellent tool for understanding the processes, such as how various environmental variables control gas emissions.
  • A complete area of landfill is monitored meter by meter with few installations of AUM. It is immaterial that landfill are above the ground that is inclining up for Hillock or landfill is in excavated or mined land.
FEATURES
Features Benefits
Continuous monitoring (CLEMS)

AUM is the only continuous monitoring system which can be easily set up. AUM monitors multiple gases in real time. There is not limit of gases that can be monitored at same time.

Measures and Monitors :- AUM monitors CH4, C2H2, CO2, H2O at ppb level precision in total methane concentration.
Meteorological Measurement

Measures meteorological factors like temperature, humidity, wind parameters (speed, direction, pressure, velocity), precipitation that show how pollutants are transferred from source to recipient.
Sensing Area distance

Area covered by AUM is 10mm to 5 Km in radius. The unit can be rotated3600. Data of air can be collected vertically as well as horizontally at distance of every 100mm to 5km as required. The laser beam travels to the targeted area / source of pollutants. With few nos. of installation complete area of landfill can be monitored for pollutants and weather conditions.

Drone Emission Surveillance

AUM PORTABLE EMISSION MONITORING SYSTEM (AUM PEMS) is integrated with Drone for surveillance purpose over the Landfill.

Drone Acharya swarms and collects data using AUM_CEMS integrated with Wireless Sensor Networks.
APPLICATIONS
  • LANDFILL, SOLID WASTE MANAGEMENT AND CO GENERATION SYSTEMS, JUNKYARDS, LARGE SCALE BURNING OF HAZARDOUS COMPOUNDS, DEBRIS (POST WAR) ETC.
