An engineering practice, hands-on experience
Pure Flux is a French engineering company (SASU) based in Saint-Martin-de-Londres, near Montpellier. The practice focuses on fluids engineering — water supply, water treatment and wastewater treatment — alongside the wider building-services disciplines: thermal, HVAC, hydraulic and electrical engineering.
The company brings together more than a decade of hands-on experience in membrane water treatment: technical audits, process design, equipment specification, and on-site commissioning of ultrafiltration and reverse-osmosis plants for municipal utilities and industrial clients across Europe.
We are partners of leading European equipment manufacturers and work with modern membrane technology — ultrafiltration and reverse osmosis — capable of treating well water, river water, sea water, high-mineralization water, wastewater and landfill leachate alike.
Our goal is a technological solution with a long service life and low operating cost — one that guarantees operational quality and the greatest possible benefit for the customer from the finished project.
What we design
- Ultrafiltration system design for open-source, well, sea and wastewater
- Reverse-osmosis system design for drinking water, boiler-water desalination, seawater treatment and two-stage demineralization
- Pretreatment design for various sources — disc-screen filters, clarifiers, settlers
- Water chemistry expertise
- Hydraulic plant design and head-loss calculation
- Mechanical design and specification — pumps, pipes, valves, corrosion-resistant materials
- Control-system design, process automation and algorithms

Fluids & water-treatment engineering
Global-brand components, individually engineered
We select tested, available components from established European and international manufacturers, then engineer the plant around them — so every project benefits from proven hardware without the cost of building bespoke equipment from scratch.
