The AbTech Contactors were designed to remove the hydrocarbons present in the produced water in order to protect and thereby substantially increase the useful life of downstream treatment equipment and technologies including a reverse osmosis system.

AbTech’s work included installing engineered pretreatment filter systems, operating at variable flow rates between 150 to 300 gallons per minute, reducing difficult contaminants, and achieving materially lower costs per barrel of produced water treated.

The company said the Smart Sponge Mixed Media Contactors removed 99.99% of the free oil and dissolved phase hydrocarbons.

AbTech COO Jonathan Thatcher said the company’s field operation and positive results demonstrate the benefits of the Smart Sponge Technology for on-site produced water treatment.
