Intracep Receives Second Utility Patent on PRW Technology

Erick McWayne — Fri, 26 Jun 2020 23:38:23 GMT

The US Patent and Trademark Office has issued a second patent for permeable reactive weir (PRW) technology. This new patent includes a vast array of water treatment equipment, valves, pumps, jacks, bubble diffusers, fish sensors, and telemetry for tracking PRW performance. The new patent also includes connecting the PRW to various power sources including integrated micro hydroelectric, solar thermal, and photovoltaic.

Demonstration Projects in CA, CO, OR, TX, and WA

Erick McWayne — Wed, 16 Jan 2019 23:59:01 GMT

Intracep is seeking new partners to help test and demonstrate the effectiveness of permeable reactive weir technology. To kick things off, we are looking for projects in California, Colorado, Oregon, Texas, and Washington. Please feel free to contact us if you or someone you know may be interested in conducting a demonstration project. Ideal projects will have influent water quality that is within one order of magnitude of applicable standards (e.g., influent that is ten times the standard or less).

Patent Issued for Intracep's Permeable Reactive Weir

Erick McWayne — Tue, 13 Nov 2018 23:32:06 GMT

After 4 years of hard work, Intracep has been issued a patent on permeable reactive weirs (PRWs). The patent provides Intracep with the sole rights to manufacture and distribute PRWs with opportunities to license the technology to regional partners.

Now it's time to build the prototypes and get them tested in the field. Off to the races!

Intracep Files Patent Application for New Surface Water Remediation Technology

Erick McWayne — Mon, 12 Nov 2018 21:36:13 GMT

Intracep filed a new patent application to build upon our existing patent. The new patent application includes the potential for adding an energy source to the permeable reactive weir. The power source may be electrical, mechanical, or thermal. The new application also includes adding various water treatment equipment and sensors to the device to improve performance, monitoring, and automation. Together with the original patented technology, the PRW will be able to handle nearly any scope of work from stormwater treatment to surface water remediation.

Permeable Reactive Weir Patent Approved by U.S. Patent and Trademark Office

The United States Patent and Trademark Office has issued a notice of allowance for Intracep's Permeable Reactive Weir utility patent.

Broadening PRW Patent - Request for Continued Examination

Erick McWayne — Wed, 28 Feb 2018 20:12:15 GMT

In late 2017, the PRW patent was deemed allowable by the US Patent and Trademark Office. After close examination of the allowed patent claims, we decided to add four new claims which provide broader protection for the invention and greater design flexibility. We anticipate getting final approval later this year. With the broader claims, the entirety of the PRW technology will be protected under US patent law.

We are looking forward improving water quality and aquatic habitats throughout the country in the near future.

I'm sure the fish are looking forward to that too!

Permeable Reactive Weir Patent Approved in the US!

Erick McWayne — Mon, 27 Nov 2017 20:36:39 GMT

The general utility patent for the permeable reactive weir (PRW) has been approved by the US Patent and Trademark Office. Now, off to the races! We only have 6 weeks to draft and file our additional 20 claims for the Continuation In Part patent application.

Stay tuned for some extensive PRW technology advancements!

New PRW Technology Patent

Erick McWayne — Thu, 28 Sep 2017 19:23:04 GMT

Intracep is developing new permeable reactive weir technology to enhance the performance and minimize maintenance requirements. The new technology will extend the service life of the PRW media cartridges, while improving pollutant removal efficiencies. New media specifications are being added to the patent to provide greater control of hydraulic conductivity and target a wider range of contaminants. These new features will compliment those specified in the original general utility patent. The new patent will be filed domestically in 2017 and internationally in 2018.

Intracep files US design patent application for the Permeable Reactive Weir

Erick McWayne — Wed, 26 Aug 2015 23:28:47 GMT

The design patent application was filed with the US Patent and Trademark Office today. The patent covers the appearance of the Permeable Reactive Weir.

Working on Design Patent for Permeable Reactive Weir

Erick McWayne — Wed, 04 Mar 2015 19:06:30 GMT

The general patent was filed May 12, 2014. We are not working on the design patent, which is how the device will look in its various configurations. There are a lot of possibilities so we have been working on a lot of different drawings. We anticipate filing in the next few months.

Permeable Reactive Weir Technology Introduced at Stormwater Treatment Training in Honolulu, HI

Erick McWayne — Mon, 19 Jan 2015 19:03:12 GMT

I shared info regarding the permeable reactive weir with my students at the two day Stormwater Chemistry and Applications to Monitoring and Treatment training at Hawaii Department of Health in Honolulu on January 23, 2015. Both Maui County and the Navy expressed interest in doing a pilot study on the technology.

Intracep at StormCon 2014 to share information about the Permeable Reactive Weir

Erick McWayne — Thu, 07 Aug 2014 21:16:18 GMT

I just returned from StormCon 2014 in Portland, Oregon. The conference had a great turnout, good speakers, and knowledgeable exhibitors. I attended most of the BMP Case Studies and Advanced Research Topics sessions and visited all the exhibitors involved with stormwater treatment to learn about the latest technologies and explore potential product collaboration. The conference provided a great stormwater science update and an overview of current research topics.

My favorite talks included:

Jennifer McIntyre's talk on stormwater toxicity and the efficacy of bioretention (does a great job removing highway runoff pollutants - juvenile coho die in pure highway runoff);
University of Idaho's talk on biochar removal efficiencies (doug fir biochar is better than Kentucky bluegrass);
Lisa Rozmyn's talk on the Washington Stormwater Center's roof runoff study (asphalt shingles aren't that bad compared to the alternatives); and
City of Portland's talk on bioretention plants (sedges are better than cattails and sunflowers).

StormCon will be in Austin, Texas next year - August 2 - 6, 2015. As if I needed another reason to go to Austin. I'll be there!

Intracep has filed an extensive patent application for a brand new class of water treatment technology called a permeable reactive weir

Erick McWayne — Mon, 12 May 2014 23:03:07 GMT

Intracep has filed an extensive patent application for permeable reactive weir (PRW) technology. This innovative surface water treatment technology is a small concrete dam with multilevel fish passage built in. Like traditional surface water weirs, PRWs create step pools that settle particulates and oxygenate the water. Unlike traditional weirs, the PRW removes pollutants (including thermal) and provides fish passage.

After nearly a year of research and design, the PRW technology is now patent pending.

Intracep developing patent on a new class of water treatment device

Erick McWayne — Thu, 06 Jun 2013 04:54:34 GMT

Intracep has signed an agreement with Lane Powell to assist us with patenting a new class of water treatment technology that can remove pollutants (including thermal) from surface water, while increasing DO and providing fish passage.
