Demo System for Direct Potable Reuse

 Orthos Liquid Systems, Inc.,(ORTHOS) announced today the release of its Proteus™ Ozone+Biologically Active Filter (O3+BAF) Demonstration System to be primarily used at direct potable reuse (DPR) demonstration facilities. The 20 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-1 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 7.5 ft2 BAF to create 22.4 minutes of empty bed contact time at 20 gpm. 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.”

Proteus™ is immediately available for procurement, submittal evaluation, production, and commissioning. Extensive factory support is offered by ORTHOS to ensure optimal operation. Contact Stuart Humphries with all Proteus™ inquiries.

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.
