How does a Watermaker remove the salt from sea water?

Are you planning a sailing trip or living on a boat? If so, you may be wondering how to get fresh water while you're out at sea. One solution is a watermaker, a device that can turn saltwater into freshwater. But how does a watermaker remove the salt from seawater?

First, let's understand the process of desalination, or the removal of salt from seawater. There are several methods for desalination, but most watermakers use reverse osmosis, a process that uses pressure to force seawater through a semi-permeable membrane. The membrane only allows water molecules to pass through, while larger salt molecules are left behind.

To start the process, seawater is pumped into the watermaker and enters a high-pressure pump. The pump increases the pressure of the seawater, which is then directed towards the semi-permeable membrane. The pressure forces the water molecules through the membrane, leaving the salt and other impurities behind.

The freshwater that passes through the membrane is sent to the water tankThe water that is left behind, now containing a higher concentration of salt, is called brine. The brine is then disposed of by discharging it back into the ocean.

Watermakers can produce freshwater at a rate of several gallons per hour, depending on the size and efficiency of the unit. They are a convenient and reliable way to get freshwater while out at sea.

Overall, watermakers are an effective way to turn saltwater into freshwater, using the process of reverse osmosis to filter out the salt and other impurities. If you're living on a boat or planning a sailing trip, a watermaker is a valuable tool to have on board to ensure you have a reliable source of freshwater.
