About Pure Flux

An engineering practice built on membrane-technology experience

Pure Flux is a French engineering company based near Montpellier, specializing in fluids and water-treatment engineering. We carry out the full scope of work on design, construction and reconstruction of water supply and treatment facilities — from technical audit and performance assessment of existing plants to turn-key construction of new ones. Our approach combines tested global-brand components with an individual design for every source water and every site.

Membrane treatment, matched to your water

0.02 µm membrane filtration

Ultrafiltration

A physical barrier that removes suspended solids, colloids, bacteria and viruses without chemical disinfectants. Performance stays independent of feed-water quality swings — unlike conventional sand filtration — and the compact, block-modular design needs no lifting equipment.

Desalination & demineralization

Reverse Osmosis

High-pressure membrane separation that removes dissolved salts and hardness from the ultrafiltrate. Configured as single- or two-stage systems for drinking water, boiler-water demineralization and seawater desalination, with pressure-exchanger energy recovery on larger plants.

Why Pure Flux

Four reasons clients come back

Tested, affordable engineering

We combine proven engineering methods with available, cost-effective components from established global brands — a full-service water and process treatment offer that lets you focus on your core business.

An individual design, every time

Flexible plant engineering based on source-water analysis and product requirements: an individual design system and an optimal equipment package for each case.

Compact, ready-to-use units

Containerized equipment with an integrated climate system, delivered ready to run — saving time on site and reducing capital cost, including rapid deployment for short-term or emergency needs.

Competitive, transparent cost

Without the overhead of a large water corporation’s offices, staff and marketing, our proposals stay cost-competitive at any capacity or water quality a project requires.
