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 through the osmotic membrane.
The AQUA-BASE ESW desalination unit is composed of:
- A sea strainer
- A low pressure pump driven by an electric motor 12 or 24VCC
- A 5µ filter (with cartridge)
- A hydraulic amplifier to increase the pressure of seawater up to 20 / 65 bar (depending on the 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 and all controls necessary to the operation of unit
- A salinometer and a valve which automatically manages the produced water flow according to its quality
- A LP (Low-Pressure) and HP (High-Pressure) pressure gauge
- A LP (Low-Pressure) vaccum switch
- A fitting Kit for R/O unit installation
- The hull fitting and hull valve are not included in the supplies
- A semi automatic rinsing system (Extra)
- A remote control (Extra)
- An 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.
