How Does Reverse Osmosis Desalination Work?

Semipermeable Membranes are at the Heart of RO Systems

The process of Reverse Osmosis Desalination (RO) represents the finest level of liquid filtration available today. While ordinary liquid filters use a screen to separate particles from water streams, an RO system employs a semipermeable membrane that separates an extremely high percentage of unwanted molecules.

For example, the membrane may be permeable to water molecules of dissolved salt. If this membrane is placed between two compartments in a container and a salt solution in one half of the container and pure water in the other, water passes through the membrane while the salt cannot.

Cross-Flow Filtration Permits Long-Term Performance

While the principles of reverse osmosis are simple, in practical terms, the RO process cannot go on indefinitely unless steps are taken to ensure that the membrane does not become clogged by the precipitated salts and other impurities forced against by the pressurized stream of feed water. To significantly reduce the rate of membrane fouling, RO systems employ cross-flow filtration, which allows water to pass through the membrane while the separate flow of concentrate sweeps rejected salts away from the membrane surface.

Watermakers, Inc. RO systems are designed optimal performance, minimal maintenance and long life.

Pressure is Applied to Reverse Natural Osmotic Flow

Now a fundamental scientific principle comes into play. That is, dissimilar liquid systems will try to reach the same concentration of materials on both sides of the membrane. The only way for this to happen in our example is for pure water to pass through the membrane to the salt water side in an attempt to dilute the salt solution. This attempt to reach equilibrium is called osmosis. However, if the goal in our water purification system is to remove the salt from water, it is necessary to reverse the natural osmotic flow by forcing the salt water through the membrane in the reverse direction. This can be accomplished by applying pressure to the salt water as it is fed into the system, creating a condition known as “reverse osmosis.”

What PSI should a watermaker operate at?

The ideal pressure for watermakers varies depending on the type of membrane used in the system. For most reverse osmosis (RO) watermakers, the recommended operating pressure is between 800 and 1,200 psi (pounds per square inch). This pressure range ensures the optimum flow rate of seawater through the RO membrane, which in turn maximizes the production of fresh water.

However, it is essential to note that not all watermakers are the same, and some models may require different operating pressures. For instance, some low-pressure systems require only 70 to 150 psi, while others may require up to 2,000 psi. It is therefore essential to check the manufacturer’s recommendations for the specific model of watermaker installed on your boat or yacht.

Another critical consideration when determining the operating pressure of a watermaker is the feed water temperature. The ideal feed water temperature for most RO watermakers is around 25°C (77°F). If the water temperature is too low, the water’s viscosity increases, which can cause a drop in flow rate and increased pressure loss. On the other hand, if the feed water temperature is too high, it can damage the RO membrane, reducing the watermaker’s efficiency.

In conclusion, the correct operating pressure of a watermaker is an essential factor in ensuring it works efficiently and produces freshwater of the highest quality. Most RO watermakers operate within the 800 to 1,200 psi range, and it is crucial to check the manufacturer’s recommendations and adjust the operating pressure according to the feed water temperature.
