As the oil and gas industry looks beyond reinjection and hydraulic fracturing reuse, produced water treatment is becoming increasingly important for both operational efficiency and sustainability. In the article, Brent Halldorson, Produced Water Expert, United States at LiqTech International, highlights one of the industry’s biggest challenges: variability. Produced water composition can change continuously between wells, operating conditions, and production methods, making stable and reliable treatment difficult.

LiqTech’s ceramic crossflow ultrafiltration systems are designed to remove suspended solids and hydrocarbons from demanding wastewater streams. By combining silicon carbide ceramic membrane manufacturing with process and system design expertise, LiqTech is able to optimize the full filtration process around the membrane technology itself.

Unlike conventional chemical treatment systems, ceramic ultrafiltration works as an absolute barrier. This helps maintain consistent effluent quality, even under variable feed conditions, while supporting automated and unmanned operation. The technology also provides strong resistance to harsh chemicals, high temperatures, and challenging oily water environments.

As produced water reuse moves toward more advanced applications, including desalination, industrial reuse, and potentially external water applications, filtration technology is becoming central to how the industry manages produced water as a valuable resource rather than a disposal problem.
