The turnkey process
From research to running plant.
One partner.
Most vendors hand you a membrane and disappear. We carry the project from your first fluid sample to the day your operators run it unsupervised.
01
Research & development
We characterize your fluid in our lab, design a custom membrane stack, and prove the chemistry on real samples.
Learn more02
Pilot plants
We ship a containerized pilot to your site or run on-skid in our facility. Real data, before capex.
Learn more03
ASME-certified fabrication
We build the full-scale system in-house, code-stamped, ready to ship.
Learn more04
Installation & commissioning
Our engineers deploy, hook up, and start up the plant on your schedule.
Learn more05
Operations management
We can run it for you, or train your team. Either way, we stay on call.

Tell us about your fluid
Have a separation problem
we should look at?
We respond within one business day. Most consultations start with a 30-minute call and a request for a small fluid sample.
- No charge for the initial consultation.
- We sign NDAs before discussing your process.
- If membrane separation is wrong for your problem, we will tell you.
