In PCAPP had been designed over the course of the prior comparison to a suspended growth process, advantages for decade, and construction was essentially completed by this application include greater resiliency during fluctuating autumn of 2012; therefore, the committee limited its con- loading, faster recovery from off-normal conditions, and cerns, findings, and recommendations to problems that longer biomass residence time.
