Sulphate Removal


Sulphate Removal Packages are automatic units that produce softened water in any flowrate. Special NF membranes are employed to meet specific industry needs in the most demanding environments, under complete reliability of operation.

The invested capital is significantly lower than competitor's due to the lack of royalties and premium prices, with our process.

Sulphates are rejected >97% at pressures between 25-35barg depending on the location, recovery factor, and temperature.

Pre-treatments and post-treatments are possible as integrated parts, optionally available on all our systems. Modules are designed in such a way that any custom solution is achieved upon Customer's request. 

Flowrates range from 100 m3/h to 2000 m3/h are achieved with a single bank of NF elements.


Special features.

The iPRO © Option.  All units can be remotely controlled by Membrane on Customer's request, or even directly by Customer via a simplified interface installed by Membrane on Customer's DCS or Control Room.

The iCon © Option. A special instrument capable of measuring the individual membrane performance. This unique, patented, feature allows for optimal maintenance over time of the membrane elements, and offers full guarantee, by analyzing the single element's operating status at the sampling rate of 1Hz. OEM warranty is fully covered when this option is installed, thus protecting the capital invested in the RO membranes.
