Capacity (TPY)
90,000
After the success of their original, 180,000 tpy positive CASP system, Napa Waste and Recycling engaged ECS to design an additional CASP system to meet the needs of Yolo County.
ECS designed and deliver an additional biolayer covered aerated static pile (CASP) system. The positive-aeration CASP has 12 independently monitored and controlled zones. The high-capacity aeration available at each zone is automatically controlled to follow the response of, and optimize the process conditions in, each batch according to an operator selected control sequence. The mechanical elements of the aeration floor under each zone are constructed entirely of rugged HDPE and stainless steel. All of which are recessed below the finished concrete surface for protection and designed for easy servicing.
