Who are we?

At APT, we know clean water is essential for a healthy life but today, increasing chemicals contaminating our water are more diverse, complex, and difficult to remove and destroy. Nearly everyone is affected by these toxins at some concentration which is why we’re an emerging contaminant treatment and remediation solutions company for the most challenging groundwater, process water, and wastewater around the world. With over 500 installations, our range of advanced oxidation and remediation solutions have successfully treated and removed everything from elevated 1,4-Dioxane and PFAS to excessive nitrate with less cost, energy use, and waste compared to alternatives.

For over 30 years, HiPOx™, PulseOx™, and AroNite® have been the treatment solution of choice for municipalities, industrial customers, government divisions, and engineering and environmental consultant firms. And now, thanks to our early 2023 acquisition by Upwell Water, we offer our “Clean water. No waste.” solutions with no upfront investment. In other words, we specialize in waste-free advanced oxidation processes (AOP) that do not create waste streams or by-products and offer it in a way that doesn’t break the budget.

Who are Some of our Customers?

We are proud to call the following sample organizations our customers and partners ranging from name-brand industrial leaders to a range of municipalities and engineering service companies.

We’re also a U.S. Small Business Association-registered company that is certified with the U.S. Government’s System for Award Management (SAM) program.


What Makes us Unique?

There is a reason we have over 500 successful water-related treatment installations around the world. We may not be the most well-known or largest solutions provider but we uniquely offer our customers and partners:

What do we Treat?

  • Turnkey, guaranteed remediation of emerging contaminants of concern in a Water-Treatment-as-a-Service model where you only pay for clean water by the gallon

  • Flexible project financing for lease and lease-to-purchase options

  • Simple, cost-effective treatment of challenging water using powerful oxidation/reduction chemistry

  • Wide applicability with proven results across each type of application, from groundwater remediation to direct potable reuse (DPR).

  • A more sustainable approach including renewable process inputs (i.e., oxygen, hydrogen, power), lower power consumption, green process chemistry, and low or no process residuals for clean, waste-free water

  • Process and performance guarantees

With our proven, patented advanced oxidation and reduction technologies, we’re able to effectively and affordably treat a range of challenging contaminants in groundwater, process water, and wastewater including:

To understand how pervasive the water contaminant problem has become, here’s a look at some of the more challenging ones we effectively treat and/or remove and how much they have spread throughout the U.S.
