Aerated Static Pile (ASP) Composting

You can rely on ECS aerated static pile (ASP) compost systems to be an efficient tool to control odors and make great compost. Our systems feature dynamically controlled aeration with a wide range of air delivery rates required to keep oxygen and temperature at Best Measurement Practice levels throughout the pile. At the same time, they are the most energy-efficient aerated static pile system (measured by air-volume delivered/unit of fan energy used) in the industry. Our dedication to continuous improvement has led to ASP designs that simplify construction, provide uniform distribution of air, are uniquely effective at controlling leachate, facilitate maintenance, simplify operations, and will run reliably for decades. ECS aerated static pile composting come in positive, negative, and reversing aeration systems; bunker-wall, mass-bed, and in-vessel configurations; and are sized and equipped to best fit your site, feed stocks, and economics.

Aerated Static Pile Composting Standard Features

ECS aerated static pile systems (ASP) can offer the following standard features depending on your operation needs:

aeration system

Air Distribution for ECS Aerated Static Pile Systems (ASP)

The aeration system distributes air through the biomass to enhance composting conditions. All process air exhausts through an ECS-designed biofilter. All aeration components in contact with the compost’s corrosive exhaust air-stream are made from stainless steel or polymeric materials. The aeration system is designed to conserve energy with variable speed fans, and adaptive control strategies. Motorized dampers control airflow and direction to each pile. Damper position is automatically set by the control system.

ASP Aeration Floors

ECS offers several different below and above grade aeration floors that distribute air through the biomass and are compatible with loading and unloading using front-end loaders. Our below-grade Low Friction Trench and Sparger pipe aeration floor collect condensate/leachate, are plug-resistant, and are designed with ease of construction and maintenance in mind.

Control for Aerated Static Pile Systems

ECS’ CompTroller™ is an automated aeration control and monitoring system that is operating at all ECS compost installations. It is designed to achieve regulatory compliance; offers operators a broad range of process options; and provides each pile/zone with independent and automatic control for achieving process goals. It allows the operator to set aeration rates very low (anoxic conditions) if conserving moisture and fan power is the highest process-setting priority; or higher to reduce temperature and increase drying rates. The CompTroller™ is remotely accessible via the web and is flexible, robust, and keeps your data safe.
