Membrane Filtration

De Nora Water Technologies offers the UAT™ Reverse Osmosis (RO) Membrane Filtration Systems to meet any tap, brackish or seawater application need.

Using high quality components, the skid-mounted  membrane filtration systems are engineered to effectively produce treated water, free of particulate matter or contaminants.

The UAT™ RO membrane filtration systems range in standard output capacities from 4.7 m³/hr to 78.9 m³/hr or 30,000 GPD to 500,000 GPD, with larger custom units available. Our experienced process engineers have a long history designing and installing the UAT™ RO filtration systems.

De Nora Water technologies offers a variety of system accessories for use with our reverse osmosis membrane filtration systems. Accessories include:

  • backwash systems for media filtration,
  • chemical dosing systems,
  • clean-in-place systems
  • media filtration systems


We offer the UAT™ EDI electrodeionization system, ideally suited for polishing reverse osmosis (RO) permeate, replacing conventional mixed bed ion exchange systems by eliminating the need to store and handle hazardous chemicals used for resin regeneration and associated waste neutralization requirements. Systems are available with a maximum permeate flow rate of 2.2 m³/h - 104 m³/h or 10 GPM - 460 GPM.
