The extensive municipal WWTP was required to upgrade its effluent quality to include extensive Ammonia removal. The project was conducted by Aqwise’s partner in North America, Siemens Water Technologies Corp.

The city of Folkstone, Georgia, needed to upgrade its lagoon system to meet new regulation regarding Ammonia removal. The extensive system consists of primary lagoons, followed by a constructed wetland and discharging the effluent into the Okefenokee Swamp.

The upgrade project was to be accomplished with minimal downtime and minimal expansion of the existing facilities.

An application of the AGAR® technology in an MBBR configuration was installed in order to achieve the required level of Ammonia. In this configuration, very little excess sludge is produced in the process, due to the low reproduction rate of the nitrifiers. As a result, no clarification is required following the MBBR, nor sludge recirculation, removal or treatment. This simplifies the maintenance procedure, as well as reducing operating expenses in comparison to conventional methods.
