BioACTIFLO Pilot Plant Case Study - City of Akron, Ohio

Many utilities are faced with the challenge of providing additional peak wet weather treatment capacity at their wastewater treatment plants and within their collection system. This need is being driven by a host of factors, the most significant of which is the focus by regulators on overflows and bypasses. If improvements are not required by a consent decree or other regulatory order, they are increasingly being mandated by conditions in permit renewals. In the City of Akron, Ohio case this requirement was mandated through a federal consent decree with USEPA. One of many items identified in the consent decree was to eliminate secondary bypasses within the Water Pollution Control Station (WPCS). Prior to the consent decree the City had conducted traditional 1 – 2 day pilot testing of various systems to treat secondary bypasses but only for the removal of suspended solids. The USEPA mandated the City pilot test and install a BioACTIFLO system for additional biological treatment as well as TSS removal. The pilot outcome coupled with the success of a step feed pilot system would determine the full scale design capacity of the BioACTIFLO treatment system. Hazen and Sawyer PC was selected by the City to operate, maintain, sample and test the BioACTIFLO pilot system.
This presentation will focus on the event forecasting, operations, maintenance and testing of the pilot as well as the results from pilot performance, field testing and bench top disinfection, coordination with WPCS staff and issues worked through during the sighting and startup. We will also cover the development of the Standard Operating Procedures (SOPs) that were implemented for the operation of the pilot as well as sample collection and field testing. Additionally, we will cover a typical event, detailed operational, sampling and field testing as well as pilot performance, testing data results, bench top disinfection procedures and sampling preparations procedures. As well as collaboration efforts between Project Management, WPCS staff, engineers, operations engineers and Kruger.
