Report proprietary technologies. Many of these technologies were well proven, while almost an equal number were in the early phases of development and without peer-reviewed data. Below is a description of the considered technologies. A few of the technologies are common and are not associated with a brand name, while other technologies have specific propri- etary properties and are associated with a particular brand. Inclusion of brand names is not an endorsement. Primary treatment technologies: • M2 Renewables' MicroScreen • Salsnes Filter • Chemically enhanced primary treatment (CEPT) • Veolia's Actiflo™ enhanced high rate clarification (EHRC) Secondary treatment technologies: • Shortcut nitrification denitrification (Severn Trent Services using its deep bed filter system) • Severn Trent Services' TETRA Denite system • Anaerobic ammonium oxidation (Anammox) • Upflow Anaerobic Sludge Blanket (UASB)/Expanded Granular Sludge Bed (EGSB) • Aerobic granular sludge (e.g., the Nereda Process) • Biologically active filtration • Anaerobic membrane bioreac- tor with and without granular activated carbon Grundfos' • • • Biobooster (Ceramic MBR) — Low SRT MBR with physical membrane scouring Emefcy's Spiral Aerobic Bioreactor (SABRE) Emefcy's Bioreactor (EBR) • High efficiency blowers (e.g., APG-Neuros's Turbo Blower). • American Water's NPXPress. • Noram Engineering's Vertreat Process Tertiary filtration technologies: • Water Tectonic's Electro- coagulation and Filtration • Parkson DynaSand Ecowash • Schreiber's Fuzzy Filter Tertiary disinfection technologies • Pasteurization Technology Group's Pasteurization System • Aquionics/Dot Metrics LED UV disinfection wateronline.com ■ Water Online The Magazine, Wastewater Edition 23 Electrogenic Energy recovery technologies • M2 Renewables Ultra High Temperature Gasification • OpenCel Focused-Pulsed Technology • Thermal Hydrolysis (e.g., Cambi Process) • Fuel Cell Energy's Fuel Cell. • Supercritical wet oxidation (e.g., SCFI's AquaCritox) Combined treatment trains Several combined treatment trains were also considered. These systems were often propriety packaged systems or were closely linked and reliant upon each process. • CEPT + microfiltration (MF) + BAF • CEPT + IMANS • Great Circle Industries' i50 non-biological satellite treatment. • M2 Renewables — MicroScreen, BAF, filtration, disinfection. • UASB, facultative ponds, nitrifying trickling filters, filtration, disinfection Step 3: Recommendations — The technologies were
