CB&I > Biosolids Profile - ESD Class A System
London, OH
In 2006, the City of London embarked on a major expansion of its' wastewater plant including a new biosolids processing facility to replace existing conventional digesters. The new digestion system was designed as a two phase, Class A system with CB&I's ATP/ESD process.
The Phase 1, thermophilic ATP Reactor acidifies the incoming feed sludge and provides pathogen reduction in a batch feed process in compliance with the USEPA time-temperature requirements. The Phase 2, mesophilic Egg Shaped Digester (ESD), utilizes the volatile acids, generated in the first phase, to further reduce solids and produce methane, completing the solids reduction process.
