Odor Stabilization Project

Odor removal equipment

Overview of odor stabilization facility
KCES NETWORK removes the odor and harmful gas generated in the unsanitary landfill by using a blower, removes it with bio filter, and injects oxygen-rich air accompanied by aerobic microbes in bio filter into unsanitary landfill. It is a facility that turns the landfill into aerobic condition.

Overview of odor stabilization facility

Overview of odor stabilization facility
In order to reduce the stability of unsanitary landfill due to the reduction of environmental damage and the risk of gas explosion due to the odor and harmful gas (CH4, CO2, H2S) expected at the time of excavation of unsanitary landfill waste. It applies Landfill-Well system to remove harmful gases to prevent civil complaints and secure work environment stability

Structure

Structure

ARS, air/ exhaust blower and lance that converts air flow per bio filter time that functions to supply aerobic air and purify harmful gas

Features

  • · Guaranteed high stabilization efficiency

    Low pressure air injection stabilization system ensures high stabilization efficiency due to high ventilation and diffusion effect

  • · Prevent Channel phenomenon

    Prevent air channel phenomenon in the buried layer by automatic switching of air injection/suction direction in 1 hour interval

  • · Smooth Inoculation of aerobic bacteria

    Inoculation of aerobic bacteria in buried layer is smooth with biofilter passing air injection

  • · Beneficial On-site response

    Hydraulic rammer attached to backhoe inserts eliminates the need for additional boring

  • · Reduction of work time

    Construction (lance, hose replacement and lance pouring) is simple, shortening work time

  • · Very low maintenance cost

    Very low maintenance cost due to odor removal by biological treatment method

  • · Shortened construction period

    Shorten the construction period by switching the inside of landfill to aerobic in a short period of time

Expected effects

  • - Preventing harmful gas which gives harm to workers before excavation work.
  • - Stability of work due to elimination of explosion risk because it changes to less than methanol standard value generated when excavation work is carried out.
  • - Resolving the complaints caused by the landfill such as the emission of odor due to landfill gas
  • - Prevention of external leakage of secondary environment pollutants to improve the living environment and resident health in the surrounding area
  • - Prompt land use of existing landfill site
