Aeration Floors

Systems ECS Staff 07/29/2020

Aeration floors are arguably the most critical component in an aerated composting system.  ECS has invested heavily in the development of four distinct aeration floor technologies, each with its own set of pros and cons.

The primary goal is always to provide the right amount of airflow to sustain Best Management Practice levels of oxygen and temperature as uniformly throughout the pile as possible. Secondary goals include: simplifying operations and maintenance, efficiently collecting leachate, minimizing energy use, and making the floors robust. To help you choose the right floor we need to understand your tolerance for operational expenditure vs. capital expenditure, what aeration direction is required, and site tolerance for dirty water. 

Compost aeration floors are the critical interface between technology and biology. A high performance ECS aeration floor can reduce the odor and VOC emissions by a factor 10 to 100x compared to a low performing aeration floor. ECS floors achieve this by providing surplus oxygen early in the process and delivering uniform and adequate aeration to keep temperatures below
650C (1500 F). Since our first aeration floor in 1999, ECS continues to improve the durability, O&M features, and floor construction of our aeration floors used across the 60+ facilities that we support.

In-Floor:

  • Lowest operating cost
  • Lowest long term total cost of ownership
  • High peak airflow
  • Most uniform airflow
  • Superior leachate control (LFT)
  • Lowest fan power (LFT)
  • Compatible with aerated turned piles (ATP)

Above Grade:

  • Lowest capital cost
  • Best for facilities with:
  • Remote locations
  • Modest size
  • Limited time horizon
  • Low cost labor
  • Existing paved surfaces
  • Temporary locations
