Membrane
Pre-Filtration

Automatic self-cleaning screen filtration ahead of RO and UF membranes, protecting membrane surfaces from fouling without interrupting feed flow.

Two Stages Ahead of the Membranes

Filtaworx automatic self-cleaning filters run ahead of UF and RO trains as first-stage protection on raw intake, and as a second polishing stage where feed quality varies or the membrane specification is tight. Backwash is triggered by differential pressure and completes in seconds, without interrupting feed flow.

Seawater intake is the hardest version of this duty — variable turbidity, marine growth, and no tolerance for a shutdown. The same filters handle raw seawater ahead of a desalination train, continuously and without operator attention.

Membrane Pre-Filtration Challenges

Membrane Fouling

Suspended solids foul UF and RO membrane surfaces, reducing flux over time.

Frequent CIP Cycles

Clean-in-place cycles increase chemical use and take the membrane train offline.

Manual Strainers Need Watching

Manual strainers ahead of membranes need regular operator attention to stay ahead of solids loading.

Availability Lost to Cleaning

Plant availability drops every time pre-filtration requires a shutdown to clean.

Variable Feed Water Quality

Changing inlet conditions make a fixed manual cleaning schedule unreliable.

Shortened Element Life

Undersized or worn pre-filtration passes fine solids that shorten membrane element life.

Filtaworx Membrane Pre-Filtration Benefits

First- and second-stage screen filtration for UF and RO plants, including raw seawater intake for desalination.

Feed Flow Never Stops

Continuous automatic backwash keeps the screen clean without interrupting feed flow to the membrane train.

Consistent Filtration Degree

A fixed screen aperture holds the solids loading reaching the membrane surface steady, instead of drifting as a manual element blinds.

Fewer CIP Cycles

Lower solids loading means fewer clean-in-place cycles, cutting chemical consumption and downtime.

Cleaning on Demand, Not on Schedule

Differential-pressure-triggered backwash responds to actual solids loading rather than a fixed calendar.

Longer Element Life

Reduces the risk of premature membrane fouling and the replacement cost that follows it.

Built for Continuous and Remote Duty

Suits continuous-duty membrane plants, including remote or minimally-staffed sites.
