A private operator in the Northwest needed to replace and improve their covered aerated static pile system which was under sized and under performing. They selected ECS to the design and supply a positively aerated pipe on grade system complete with CompTrollerTM and temperature feedback process control.
ECS delivered a pipe on grade, positively aerated static pile composting system. This design delivers high aeration rates, which helps facilitate good process conditions which lead to low odor composting. The main aeration fan maintains a duct static pressure setpoint in the main distribution duct. As the temperature probes send feedback to the CompTrollerTM automated control system, dampers modulate the airflow into the zones.
In addition, pipe on grade can achieve very low installation costs. While most water boards require an impervious surface, it usually does NOT require concrete. In addition, this approach allows a mass-bed configuration (no walls between zones). This approach can save money while still maintaining rapid composting of food waste, yard waste, biosolids, or other organic feedstocks.
