Reverse osmosis (RO) is used to remove dissolved materials in water. The most well-known application is the production of drinking water from seawater.
Reverse osmosis (RO) is a water purification technology that uses a semi-permeable (semipermeable) membrane to remove ions, molecules and larger particles from water. Turbin develops and produces customer specific reverse osmosis installations for various applications. We also supply ATEX RO installations for processing waste water, off-shore and maritime applications. Turbin takes care of the complete unburdening and installation of the system. We also have various reverse osmosis rental installations available. The pilot installations are available to test your application on partial flow.

The power of Reverse Osmosis
Reverse osmosis uses a semipermeable membrane to remove particles from water. These particles are, for example, molecules, ions and larger particles. The filtering effect of the membrane is achieved by applying a pressure difference. The water with the dissolved substances will then move to the side where the sum of the external pressure and the osmotic value is the lowest. If the external pressure on the side of the concentrated solution is large enough, the pure solvent (without taking the solutes) will be pressed to the other side. As a result, the solute remains on the membrane and a pure solvent is obtained.

Good pre-treatment with both mechanical and chemical treatments is crucial for an RO system to prevent contamination, scaling and costly premature RO membrane failure and frequent cleaning requirements. Below is an overview of common problems that an RO system experiences as a result of a lack of proper pre-treatment.
Pollution occurs when contaminants accumulate on the membrane surface, causing the membrane to clog. There are many contaminants in the municipal water that are not visible to the human eye and that are harmless to human consumption, but large enough to quickly pollute an RO system. Pollution often occurs in the front end of an RO system and results in a higher pressure drop across the RO system and a lower permeate flow. This results in higher operating costs and ultimately the need to clean or replace the RO membranes. Pollution will eventually occur to some extent given the extremely fine pore size of an RO membrane, regardless of how effective your pre-treatment and cleaning schedule is. However, if you have a good pre-treatment, you minimize the need to deal with pollution-related problems on a regular basis.
Pollution can be caused by, among other things, the following:
- Particulate or colloidal material
- Organic substances
- Micro organisms
- Scaling (eg precipitation of calcium carbonate)
Pre-treatments that we offer are for example Ultrafiltration.
The filtering effect of ultrafiltration remains active at all times, the basis of the filtration is based purely on mechanics. This way of filtering water is therefore very effective and sustainable. Ultrafiltration with membrane technology originally came from the healthcare system, namely kidney dialysis. Dialysis is the exchange of substances dissolved in water through a semipermeable membrane. This filter technique is similar to microfiltration, nanofiltration and reverse osmosis. The difference is in the pore size of the membrane.
The power for ultrafiltration is a difference in pressure across the membrane from food to filtrate side. The membrane prevents larger particles than the membrane pore. The separation of microfiltration is thus realized on the basis of particle size, it is a physical separation method.
Membranes can be operated dead-end or cross-flow. At dead-end all the water is forced through the membrane. In the case of cross-flow, the supplied raw water is circulated along the membrane surface. This creates speed and turbulence whereby heavily polluted water can be treated.
