What Purecycle Actually Does
Purecycle Technologies operates a water purification facility in Ironton, Ohio, that uses a proprietary steam reforming process to treat contaminated water. The system works by heating wastewater until it turns to steam, then condensing it back into liquid. Contaminants stay behind in the boiling chamber while the pure water vapor is collected. It is not reverse osmosis. It is not nanofiltration. It is a phase change separation method that can handle brackish water, produced water from oil and gas operations, and landfill leachate. The Ironton facility is their demonstration and pilot scale operation. They have been working with various industrial clients to prove the technology before scaling up. The location in southern Ohio is not random. Ironton sits near the Ohio River and has existing industrial infrastructure that makes it practical for testing at this scale. I worked with a client who had a site in West Virginia dealing with high-TDS produced water from an older oil well. The conventional options were either trucking the waste out for disposal or running a reverse osmosis setup that kept fouling. The RO membranes lasted about three weeks before flux dropped below usable levels. We brought in Purecycle's system on a trial basis. The steam reforming approach handled the salinity without the membrane replacement cycle. We went from changing filters every month to running continuously for six weeks with only routine maintenance stops.
The catch nobody mentions upfront is energy. This process requires significant thermal input. If you do not have a cheap heat source available on site, the operating costs climb fast. You are essentially boiling water to separate it from dissolved solids, which takes roughly 540 BTU per pound just for the phase change, not counting heat losses or pump energy. At an industrial scale that adds up to real fuel costs. At the Ironton demo site they have access to natural gas which keeps things manageable. If your site runs on electric resistance heating, you need to do the math differently.
How the System Works in Practice
Feed water enters the pre-treatment stage where large particulates and oils are removed. This step matters because any suspended solids or floating hydrocarbons will interfere with the boiling chamber. Purecycle's pre-treatment typically involves a combination of filtration and skimming. From there the water moves into the evaporation chamber where it is heated above its boiling point. The steam rises and passes through a condenser where it returns to liquid form. The concentrated brine remains in the boiling chamber and is periodically purged. The output water quality depends on what you are feeding in. For typical industrial wastewater you are looking at total dissolved solids reduction in the 99 percent range. Heavy metals, radionuclides, and most organic compounds do not vaporize and stay in the brine. The condensed water can meet drinking water standards if the feed water is within certain contaminant thresholds. It cannot handle volatile organic compounds that boil at similar temperatures to water without additional treatment stages. That is an important limitation. I ran into this exact problem with a client whose landfill leachate contained traces of benzene and toluene. The steam reforming stripped those compounds into the vapor phase along with the water. We had to install an activated carbon polishing step downstream to catch the VOCs before the water met discharge standards. Budget an extra 10 to 15 percent of your capital cost for this kind of post-treatment if your feed water has any volatile organics.

Common Pitfalls
The biggest mistake I see people make is assuming this is a drop-in replacement for RO without proper feed water analysis. You need a full water composition report before you size the system. Things like silica concentration matter more than most operators realize. Silica can deposit on the heat exchange surfaces and reduce thermal efficiency over time. If your feed water has silica above 50 parts per million, you will need a softening or antiscalant program running before the water reaches the evaporator. Another issue is brine management. The concentrated waste stream from Purecycle's process is not harmless. It is highly concentrated brine with all the original contaminants plus whatever volatiles got stripped. You cannot just discharge this anywhere. Depending on your local regulations you may need to handle it through evaporation ponds, deep well injection, or a contract with a brine disposal service. Factor this into your operational planning or you will hit a regulatory wall within a year. The system also requires consistent feed water flow. It is not designed for batch processing or intermittent operation the way some other technologies are. If your wastewater generation is cyclical, you need a holding tank that can buffer the fluctuations. I have seen operations try to run Purecycle systems on flow rates that varied by 40 percent between shifts. The thermal balance gets thrown off and you end up with inconsistent output quality and unnecessary shutdown cycles.
When This Makes Sense
This technology shines when you have high salinity wastewater that RO cannot economically handle, when you need to recover pure water from contaminated sources for reuse, or when disposal costs for liquid waste are prohibitively expensive. It is also relevant for mining operations, power plant cooling water blowdown, and food processing facilities with high organic load wastewater. If your main goal is simply lowering TDS on moderately saline water, conventional RO or electrodialysis will likely be cheaper on a per-gallon basis. The steam reforming approach is overkill for that scenario. It is built for harder cases where other methods break down or become uneconomical due to membrane replacement and chemical dosing costs. The Ironton facility offers pilot testing if you want to evaluate the technology for your specific wastewater. They run continuous tests on your feed water and give you actual performance data rather than lab estimates. I would recommend doing this before committing to a full installation. The difference between published specs and real world performance with your particular water chemistry can be significant, especially around energy consumption and brine volume.
There is no public download link or DIY version of this system. It is proprietary industrial equipment that requires professional engineering for installation and operation. The company provides the technology and support directly through their sales and engineering teams. If you are evaluating this for a project, start with a water analysis and a pilot test at the Ironton facility rather than trying to piece together a custom solution from off the shelf components.
