Field proven ceramic membranes for treating produced water

Page last modified

February 20 2026

Produced Water and Fracking Flowback water, treated to re-injection levels in one solution. The APATEQ OilPaq treatment system replaces multi-stage phase-based separation in one skid-mounted solution. A combination of UF Ceramic plate membranes and solids removal technologies are integrated into one package, to achieve flexible, robust, and high-efficiency treatment. With years of proven field experience, the OilPaq is proven to deliver discharge and re-injection specifications, across a wide range of wastewater types, with robust reliable self-cleaning capabilities. It serves as full treatment of produced water for re-injection in SWDs but also as a pre-treatment for any subsequent treatment steps to convert produced water for beneficial use.

Pros & Limitations

Low cost of operation compared to Cross Flow Tubular Membranes, the OilPaq does not need recirculation pumps. Estimated $0.07-0.15 per bblw OPEX costs

Replace multi-stage gravity based separation, cyclones and flotation arrangements, into one treatment process

Reliable membrane operation with stable flux management

The OilPaq can achieve Inlet concentrations of 1000ppm to <1ppm in one system

Years of field proven experience with ceramic membranes in service for 6 years

In-house Automation Expertise enables real time condition monitoring, system alarms, optimisation of CIP routines, remote access and remote control

Ceramic Plate Membranes require toploading access for interventions. Therefore OilPaq height cannot exceed approximately 2.3m. While solution is linearly scalable, increasing flowrates, increases the footprint horizontally

Chemically Enhanced Backwash routine will require small amounts of chemicals, for consumables
