Reverse Osmosis

Already now, but certainly in the future, membrane techniques will play an important role in most water treatment processes.

Geonwater therefore has a wide range of RO systems for both 100 liters and 30,000 liters per hour.

In addition, we are progressive in supplying fully digitally controlled, compact Units that can be integrated into an existing process environment.



Reverse Osmosis

Depending on the problem, four different membrane filtration techniques are used in water treatment. These are from coarse to fine: Micro Filtration (MF), Ultra Filtration (UF), Nano Filtration (NF) and Reverse Osmosis - Reverse Osmosis (RO). The characteristic for these four techniques is that they are pressure driven processes using semi-permeable membranes, which are the most important part of the system. Simply put, a membrane can be imagined as a sieve with microscopic holes that allow water molecules to pass through, but no other substances. These 'waste products' are disposed of with the residual water (concentrate).

In addition, Reverse Osmosis is based on the differences in concentration pressure between water with salts and pure water (without salts). realized with as few salts as possible. (permeate)

Geonwater has a wide range of RO systems, including the Eflux. This high-quality Reverse Osmosis system has been developed by Geonwater for an environment that demands operational reliability and efficiency.  The system is very compact in size, because the piping is integrated in the connection blocks.


In addition, the Eflux is easy to integrate into an existing process environment. For example, the fully digital control system can be customized to the customer and all process parameters can be made transparent as desired by means of a touch panel.

In addition to the pressure-driven membrane processes, there are water treatment processes that use potential difference as a driving force.


EDI (Electro DeIonisation) for ultrapure water applications are an example of this.

If you would like to know which membrane filtration technique is most applicable to your process, please contact one of our technicians. They are happy to think along with you and inform you about the possibilities for your location.
