How a Desalinator Works
The reverse osmosis process transforms seawater into potable freshwater
1
Withdrawal
Seawater is drawn through a sea intake with an anti-algae filter and a low-pressure pump.
2
Pressurisation
A high-pressure pump pushes the water through the membranes.
3
Reverse osmosis
The membranes separate salt and impurities from the water, making it freshwater.
4
Storage
The produced freshwater is stored in onboard tanks.

Frequently Asked Questions
Answers to the most common questions on marine water treatment
How much water does the system actually produce?
The capacity can range from 30 to 1600 lt/h depending on the model. However, the actual output is influenced by environmental factors: the water temperature (the colder it is, the lower the output) and the salinity level of the sea in which you are sailing. This is normal system behavior.
The produced water is salty: what to do?
If the water tastes bad or has too high a fixed residue, the membranes have failed. This often happens when the system remains idle for a long time without undergoing the preservation cycle (the so-called "pickling"), or if they have worked with dirty/oily water. In this case, the only effective solution is to replace the membranes.
Why doesn't the high-pressure pump go up?
In most cases, the problem is upstream. Before disassembling the high pump, do these checks:
Clogged filters: If the pre-filters are dirty, the pump does not receive enough water and cannot push.
Low pump (Booster)Check that the feed pump is running correctly and that there is no air in the circuit.
Suction lineCheck that the sea inlet is clear and that the low-pressure hose is not constricted or sucking in air.
Only if these points are OK, then the problem concerns the mechanics of the high-pressure pump.

The desalinator is switched on but does not produce fresh water: what to check?
If the system is running but not delivering freshwater, follow these technical check steps:
Quality: Look at the conductivity display. An optimal value should be below 200-300 PPM (excellent water is around 140 PPM). If the value is much higher, the system will divert the water to the sea because it is not potable.
Pressure: Check the high-pressure gauge. It should operate steadily at 60 bar.
Membranes: If the pressure is correct but the water remains brackish, the membranes are probably dirty or worn out.
