ECS engineeredCOMPOSTsystems Covered ASP and Pipe-Less Aeration The AC Composter TM(Covered ASP)and CompDogTM(pipe-less floor aeration),provide facility operators with a cost-effective tool for controlling odors,VOC and Greenhouse Gas emissions;and also for maintaining optimal pile conditions during composting. The AC ComposterTM system combines an impermeable fabric cover with the ECS CompTrollerTM,options for in-slab or CompDogTM aeration floor,and biofiltration. The AC Composter TM is appropriate for a wide range of facility sizes,and virtually all feedstocks.It can be used outside in CompDogTM discrete piles/zones;with a bunker-wall configuration to reduce (Pipe-less aeration System) the facility footprint;or inside buildings to control the odor The CompDogTM aeration floor system is an innovative and cost- and humidity associated with in-building ASP systems.The AC effective alternative to using in-slab or above-grade pipe.The Composter provides: CompDogTM uses an inflatable form to create aeration vaults under an ASP pile.The ASP pile is built on top of the CompDogTM and is allowed • Complete capture and excellent reduction of VOC and to settle overnight.In the morning the CompDogTM is removed and Greenhouse Gas emissions leaves behind an aeration vault used for air distribution through the • Superior odor control biomass.The CompDogTM system includes a CompDogTM Roller and • Minimized evaporative water losses from the biomass Inflation and Deflation mechanisms.ECS also offers an In-Slab aeration • An effective barrier against vectors(birds,rats,flies) floor that collects condensate and minimizes labor. • Accommodates a broad range of aeration rates and process Aeration, Control and Monitoring System control options The AC Composter uses ECS'proven CompTrollerTM control technology. Compost pile temperature data is collected and stored on the In r ' CompTroller.The batches of compost are easily tracked through the AC Cover " " 01 facility from start to finish.Negative aeration is automatically controlled The AC Cover is made per Operator chosen set-points.The exhaust process air captured by the of tough,UV resistant, AC Cover is scrubbed in a biofilter.The aeration rates can be set lower and waterproof fabric. to conserve moisture and fan power,without releasing odors;or higher The cover includes to reduce temperature and increase drying rates.Prior to removing the straps for handling and securing. The AC Cover is placed and removed cover the aeration rate is increased to lower pile temperatures and raise with an ECS Straddle Cover-Winder(for large facilities);or with a Front Oxygen levels to greatly diminish the potential for odor release. End Loader Assist Cover-Winder(for smaller facilities). The advantages of the AC Cover include: • Does not absorb water and become heavy • Airflow characteristics do not change with fabric soiling • UV Protected and field repairable for long service life • Largely held in-place by the aeration system(negative suction) r EMPATENTS The AC ComposterTM covered aerated pile system and CompDogTM aeration floor system are covered by US Patents 7,642,090,7,713,731,and other US and foreign patents pending.
