From treatment design to plant performance.

Independent process engineering for ultrafiltration and reverse osmosis systems, supporting new projects, plant upgrades and day-to-day operation.

Discuss your membrane project

Engineering built around your water

We assess feed water quality, treatment requirements and operating conditions to develop practical solutions for your plant. Our support covers pretreatment, membrane selection, process design, commissioning and performance improvement.

Systems we support

Ultrafiltration & pretreatment

Engineering support for UF systems and the treatment stages that protect downstream membranes.

  • Feed water assessment and pretreatment
  • UF sizing, backwash and cleaning review
  • Integrity testing and operating performance

Reverse osmosis desalination

Process design and operational support for seawater and brackish water RO systems.

  • Membrane selection, flux and recovery
  • High-pressure pumping and energy recovery
  • Permeate quality and post-treatment
