Fouling
One Treatment - Zero Compromises.
When membrane flow rates decline or micro counts rise, quality suffers and costs increase. Our patented chemistry, PURE Hard Surface, quickly penetrates even RO membranes delivering powerful pathogen elimination and effective removal of fouling, all without oxidization. By preserving membrane integrity and extending service life, our treatments delay costly replacements, maximizing your system’s return on investment.

Why switch
to pure?
Switching to PURE provides long-term value in food manufacturing and processing. While cheaper options may lower upfront costs, they lack PURE’s proven effectiveness, leading to more frequent applications, downtime, and higher labor costs. PURE’s EPA-registered, non-corrosive formula protects equipment, reduces contamination risks, and ensures compliance with food safety regulations, avoiding recalls and quality issues.

Restore Flow. Eliminate Fouling. Extend Lifespan
When membrane flow rates decline, quality suffers and costs rise. PURE® Hard Surface offers a proven, no-compromise solution that removes fouling, restores flow, and eliminates bacteria in a single treatment. Operators no longer need to rely on aggressive chemicals or complex protocols to keep systems running at their best.
Proven outcomes
From lab trials to full-scale RO and UF systems, PURE Hard Surface delivers fast, effective sanitation without damaging membranes.
- 5-minute penetration
- 8–9 log reduction
- Delayed $500K in replacement costs
Formulated without persistent chemicals, our technology is wastewater safe and does not require discharge permitting
With no PPE required and no impact on wastewater systems, it’s the easiest upgrade you’ll ever make.
Additional Insight
What are the active ingredients in PURE Hard Surface?
The active ingredients in PURE Hard Surface are Silver Ions and citric acid (both readily found in our environment), bound together to create our patented Silver Dihydrogen Citrate (SDC) technology.
How do I ensure that this chemistry is flushed out of my system?
We’ve tested both RO and UF systems and found that a simple wash is enough to reduce the 30ppm formula down to 10ppb, which is well below the strictest of standards.
Is PURE Hard Surface registered with the US EPA?
Yes, PURE Hard Surface is registered with the EPA under The Federal Insecticide, Fungicide, and Rodenticide ACT (FIFRA) and with all 50 states, the District of Columbia and Puerto Rico. The PURE Hard Surface EPA registration number is 72977-5-73912.
What is the shelf life of PURE Hard Surface?
The chemistry should be used within two years of the date of purchase. We can revalidate chemistry beyond that timeframe.
How will PHS react to higher temperatures?
This formula can be run up to the melting point of citric acid without the risk of off-gassing, unexpected chemical reactions, or reduced efficacy.
What does an application look like?
It depends on your system’s set up. PHS comes Ready-To-Use and PURE Bioscience is investing in a pump skid to optimize the transfer of chemistry into your system.
Why operators choose
“Simple, No Hassle Approach”
