All watermakers in the market are using the RO process as described previously. In Figure 3 a standard set up of your AQUAbibe watermaker in your boat is shown.
There is a high-pressure pump, which is creating the pressure of the Feed Flow (Seawater), which goes directly into the RO membranes. On the other side of the membranes a high-pressure valve is located, which is used to adjust the pressure in the membrane. The standard operating pressure is 55 bar (800PSI).
With this setup a small percentage (up to 15%) of the pumped Seawater flow passes through the membranes as fresh drinking water. The remaining volume of app. 85% of the seawater is called Brine and is discharged back to the sea.
With several valves you can operate the flow and divert the fresh water to your boat tank. You can also use other valves to pickle your system, so you can make sure, that you can store your boat for several months without harming your watermaker.
