Product Specification Sheet The EDI BioReef® system is a submerged fixed film technology that is ideally suited to improve the removal of BOD, TSS, and nitrogen in conventional lagoons or suspended growth biological processes. Treatment systems experiencing any of the following conditions will benefit from the application of the BioReef system: • • • • • Hydraulic or organic overload Inadequate BOD or TSS reduction Poor ammonia conversion High effluent total nitrogen Reduced cold weather performance Biological processes are limited in their ability to treat wastewater by the mass of microorganisms...
