Save energy

Benefit from decreased energy consumption per m3 of water through energy-efficient design features, including Grundfos E-pumps with integrated frequency converter and low-energy membranes.


Take control

Control over the process allows for optimization leading to savings on chemicals, better capacity and water savings. SE30 is a PLC-based control unit especially designed for RO-PLUS units.


Product overview

Our product range comprises a number of pre-engineered water saving RO-PLUS units with a flow rate up to 36 m3/h. The starting point is our modular-built standard system ensuring high flexibility, high reliability in operation, and short delivery time. All plants consist of selected high-quality components and intelligent features, e.g. Grundfos E-pumps that help reduce energy.

Each solution can be customized and built according to the specific application by adapting the choice of material, instrumentation, and control system - based on our combined know-how.

Upgrade to RO-PLUS saves 90,000 m3 of water annually

RO-PLUS is also available as an upgrade kit for existing water treatment systems supplied by EUROWATER. The upgrades are easy to implement, and the payback period can be as low as 6 months.

The picture shows an existing reverse osmosis unit upgraded to RO-PLUS at the Danish brewery Harboe Bryggeri A/S. The upgrade lead to 88 % water recovery which correspond to 90,000 mwater saved yearly.
