Compact reverse osmosis unit with pretreatment

Compact reverse osmosis unit - ready for use!

Membrane filtration by reverse osmosis is a pressure-driven filtration process. The system produces high purity water, removing up to 90% of the organic substances and retain 98-99% of the salt in the water.

Our serie of compact demineralization system type CU:RO consists of complete reverse osmosis system together with pretreatment - ready for use! All units are placed on the same stainless steel skid making it a space-saving plant. CU:RO is available with 1 to 5 membranes, producing 400 to 2,000 L/h of demineralized water.

The compact reverse osmosis unit is a space-saving solution making it easy to fit in an existing production facility.    


Compact solution for selected applications

A complete water treatment system with quality equipment

Softening unit

Our softening systems are equipped with a patented 5-cycle valve is made of high quality synthetic material and has few moving parts. This gives the valve reliable operation, long life and minimum maintenance.

Efficient reverse osmosis membranes

The reverse osmosis unit is equipped with low-energy membranes high retention efficiency for superior water quality. All RO membrane elements are in-stock items with short delivery time.

Integrated control system 

CU:RO is equipped with a SE30 control system integrating an operator panel and a programmable logic controller (PLC). The operator panel is accessible on the front side of the unit with output signal 4-20 mA. The menu structure is standardized and available in several languages for easy and quick access to operating data and parameter settings.

Pretreatment ensures a reliable operation

Proper pretreatment of the feedwater to a reverse osmosis system is an essential factor for unproblematic, long-term operation. Clogging of the membranes by suspended solids, scale-forming minerals, and other impurities must be prevented by appropriate measures. With a compact reverse osmosis unit pretreatment is a standard feature. The following options are available.


Softening plant

Single operation


Softening plant

Parallel operation


Clearex plant

Parallel operation with combined filling for softening and removal of free chlorine
