Membrane Water Treatment

Microfiltration, ultrafiltration, nanofiltration, reverse osmosis, fouling and desalination.

Microfiltration, ultrafiltration, nanofiltration and reverse osmosis as selective barriers.

Membrane filtration for larger suspended particles and selected microorganisms.

Tighter membrane filtration for colloids, macromolecules and selected microorganisms.

A membrane process between UF and RO for selected dissolved species.

High-rejection membrane separation for dissolved salts and many other contaminants.

Protect reverse-osmosis membranes by controlling solids and fouling risks upstream.

Particulate, organic, biological and scaling mechanisms that reduce membrane performance.

How permeate quality, normalized performance and integrity checks support confidence in a membrane barrier.

Why fouled membranes require manufacturer- and chemistry-specific cleaning programs.

The retained stream from NF/RO and why treatment does not make contaminants disappear.

RO and thermal methods for reducing dissolved salts in brackish water or seawater.

Use evaporation and condensation rather than a membrane to separate water from salts.
