A – THE WATERMAKER
1 – PRESENTATION
The Watermaker is entirely hydraulic. Its only source of energy is the low-pressure water-flow provided by the booster pump. The hydraulic
amplifier system automatically regulates the osmotic pressure as well as the flow of water pumped across the osmotic membrane.
The AQUA-BASE ESB desalination unit is composed of:
- A sea strainer
- A low- pressure pump driven by an electric motor 12 or 24VCC
- A filter (with cartridge) 5µ
- The hydraulic amplifier increases pressure of seawater up to 40 / 65 bar (depends version) to allow production of fresh water through the
membrane
- A reverse osmosis membrane inside the high-pressure vessel
- A set of valves for operating and servicing the unit
- A main switch to the operation of unit
- A pressure gauge LP (Low-Pressure) and HP (High-Pressure)
- Fitting Kit for R/O unit installation
- Hull fitting and hull valve are not included in the supplies
- Electric box Dual voltage (EXTRA).

(1) The pressure is automatically adjusted, depending on operating conditions (water salinity and temperature).
(2) The nominal capacity is given for a new unit, nominal membranes performances, operating in standard seawater TDS 35000ppm (35g/l) and temperature
25°C. The capacity can vary from +/-10%, according to allowances given by the manufacturers of the membranes.
