ORTHOS Proteus™ O3+BAF Demo System

for Direct Potable Reuse

Orthos Liquid Systems, Inc., (ORTHOS) Proteus™ Ozone+Biologically Active Filter (O3+BAF) Demonstration System is primarily used at direct potable reuse (DPR) demonstration facilities. The 20-200 gpm Proteus™ O3+BAF System delivers to utilities a larger-scale, longer-term solution than pilot columns to demonstrate the carbon-based removal of total organic carbon (TOC) and other chemicals in order to achieve high-quality purified water. The Proteus™ forms the core element of carbon-based DPR treatment that meets or exceeds applicable drinking water quality standards while mitigating the brine disposal challenges of processes using reverse osmosis

O3+BAF Demonstration System

To create the Proteus™, ORTHOS formed a strategic agreement with Pure Flow Ozone Division, the exclusive US and Canadian municipal engineering partner of Primozone®, a leading manufacturer of ozone generators. The Primozone® GM-series reactor utilized in the Proteus™ provides straight-forward, efficient operation and minimal maintenance in a compact footprint—an optimal solution. Ozone is dosed based upon influent concentration of TOC (plus nitrite, optionally), monitored by Proteus™ instrumentation.

After the influent TOC is oxidized, O3-treated water is pumped to the ORTHOS BAF utilizing media-retaining ORTHOS Type D nozzles in an underdrain plate. Up to 96” of media (e.g., GAC, anthracite, sand) may be installed in the BAF to create 20+ minutes of empty bed contact time. Proteus™ pumps and compressor provide user-adjustable, concurrent air-water backwash, triggered manually or automatically based on headloss across the filter media, runtime, or turbidity.  

The Proteus™ operator panel (with Allen-Bradley CompactLogix PLC and HMI) provides real‑time monitoring and control of all instrumentation, automated valves, and equipment for ease-of-use.      

“With increased water scarcity, utilities are demonstrating that highly purified reuse water may augment available potable supplies. Proteus™ will prove that carbon-based strategies are extremely effective for full-scale DPR,” stated Stuart F. Humphries, Director of Filtration Technology for ORTHOS. “Proteus™ is another example of our repeated investment in the advancement of industry technology.”

“We are pleased to team with ORTHOS to support Proteus™ systems with our Primozone® generators and equipment. The modular, compact GM-series produces ozone at naturally-higher gas output pressures, resulting in increased ozone concentrations and improved dissolution in water.”

Remember Orthos’ HUGE life cycle cost benefits– At the end of the filter’s life cycle (~25 years), in contrast to a complete plastic block or folded sheet metal underdrain overhaul, nozzles are simply replaced
potentially saving $Millions.
