### MEMORANDUM

TO: Record

FROM: James K. O’Connell, ERG

DATE: January 6, 2016

SUBJECT: CoilChem, LLC Treatment Technology Memorandum ( DCN SGE 01 261 )

EPA received email communication from Michael W. Martin of CoilChem, LLC on October 1, 2015. He introduced himself, explaining that he has been involved with environmental consulting and wastewater technologies for over forty years. This memorandum is

a su mmary of Mr. Martin’s communication with EPA , which includes a summary of CoilChem

LLC ’s treatment process , a combined oxidat ion and separation technology designed to remove suspended solids

. Supplemental information about CoilChem

, LLC’s treatment technol ogy can be found in ALL Consulting, LLC ’s 2015 publication, “ Assessment of CoilChem’s Water Treatment Technology ” (DCN SGE01228). The assessment is a thorough overview of their treatment process, including water analytic results, a technology write

- up, and pictures of the test

site.

CoilChem

, LLC currently has on e fracturing fluid recycling system in West Texas

. In August of 2015, t he system was processing about 20,000 barrels of produced water per day (bbl/day). According to CoilChem, LLC, t he system ha s been in continuous operation for over 90 days without a single day of down time.

Water is pumped from the operator to CoilChem

, LLC ’s accelerated oxidation processing equipment and t he pH is measured . T he waste stream is then subjected to a hydrogen peroxide treatment to help precipitate iron, destroy bacteria, and remove dissolved solids. Using a square tubing bundle reactor with directional changes, CoilChem

, LLC creates a cavitation effect to help further disassociate solids from the water. The flu id passes through a weir tank and then through a coalescing media to assist in capturing clean oil from the surface. Finally, a biocide is injected to prevent bacterial growth while storing the water until reuse.

This CoilChem

, LLC system has a small foot print consisting of two containers , each eight by forty feet. The first container houses the proprietary Hydration/Reactor system and computer/controllers that monitor and maintain the chemistry of the water on a real time basis

. The second container house s the separation system where the solids/liquids disassociate.

According to CoilChem

, LLC , the system is achieving effluent turbidity measurements

less than or equal to 1 NTU and achieving TSS removal s of 95% or better and between 8% and
22% TDS removals when comparing the influent versus the effluent

. The system can beMemorandum

expanded to treat volumes of wastewater greater than the 20,000 bbl/day being treated at the CoilChem, LLC system in West Texas by a dding ancillary equipment.

CoilChem

, LLC believes oil and gas operators are tak ing water from aquifers at huge

rates , causing a significant drop in water levels in major Texas aquifers

. CoilChem

, LLC

believes there system could help reduce ground water depletion in many areas of the country.

CoilChem

, LLC invited EPA for a site visit and offered to share relevant data.

The website for CoilChem

, LLC is www.coilchemllc.com , and Jerry Noles , the inventor of this system, is the primary contact (800
