LiqTech supplied SiC membranes, engineering, and commissioning of the full-scale system. The fully automated system has integrated backflush and chemical cleaning in place.
The produced water in this case is a gas condensate characterized by a relatively high concentration of corrosion inhibitors. Conventional water treatment technologies, such as Hydro Cyclones and flotation units (DAF/IGF) have certain limitations in regards to solids (TSS) and oil (OiW) removal. The high concentration of corrosion inhibitors created an oil emulsion and increased the viscosity that challenged the existing produced water treatment system.
The goal was to provide a polishing treatment step downstream of the existing installation to secure full OSPAR compliance. LiqTech worked closely with our partner and end-user, which decided for the LiqTech SiC membrane technology from over +10 competing technologies.
