RO pretreatment
Stable water that extends reverse osmosis membrane life.
Industrial ultrafiltration (UF)
Industrial ultrafiltration
A physical barrier against solids, turbidity, bacteria and viruses, with no added chemicals. Ideal as reverse osmosis pretreatment and for reusing treated wastewater.

1–2,000m³ per day
What it is
Clear water, free of microorganisms.
Ultrafiltration uses membranes with pores of about 0.01 microns. Water passes; suspended solids, turbidity, bacteria and viruses stay behind. Unlike reverse osmosis, it lets salts through, so it runs at lower pressure and uses less energy.
That makes it reverse osmosis's best partner: it delivers very stable water that protects RO membranes, cuts cleanings and extends their life. It is also the backbone of many treated wastewater reuse projects.
- Membrane modules with automatic backwash
- Scheduled clean-in-place (CIP)
- PLC control panel and instrumentation
- Integration with reverse osmosis, ion exchange or UV
How it works
Filtration that cleans itself.
Typical cycle of an ultrafiltration system.
- Feed waterWell, city supply, surface water or treated wastewater.
- Pre-screenProtects the modules from large particles.
- UF modulesRemove solids, turbidity, bacteria and viruses.
- BackwashAutomatic cycles that clean the membrane.
- Filtered waterTo reverse osmosis, utilities or reuse.
Applications
What is it used for?
Wherever you need clear, safe water, or to protect a downstream process.
Wastewater reuse
Polishing treated wastewater so it can be used again.
Utility water
Clear water free of microorganisms for plant utilities.
Surface or well water
Handles variable turbidity without constant coagulant dosing.
Rinse recovery
Removes solids before recovering rinse water.
Cooling towers
Side-stream filtration to control solids.

FAQ
Frequently asked questions.
01What is the difference between ultrafiltration and reverse osmosis?
Ultrafiltration (≈0.01 µm) removes solids, turbidity, bacteria and viruses but lets salts through. Reverse osmosis (≈0.0001 µm) removes almost all dissolved salts. They are often combined: UF as pretreatment and RO to demineralize.
02Does ultrafiltration use chemicals?
Not to filter: it is a physical barrier. Chemicals are only used for periodic membrane cleaning.
03When does UF make sense as pretreatment?
When feed water has variable turbidity or solids, or when you want fewer cleanings and longer reverse osmosis membrane life.
04Can it be used to reuse wastewater?
Yes. It is one of the most common stages to bring treated wastewater to reuse quality, alone or ahead of reverse osmosis.
05What sizes do you build?
Systems from 1 to 2,000 m³ per day, sized for each plant.
