I. SYSTEM INSTALLATION MODEL

II. PRINCIPLES OF OPERATION

The system works by following steps:

- Seawater is drawn by the source pump. If the water pressure is weak or there is no water, the system cannot turn on the pump.

Pumping water pump source  through the pre-filter column and through the PP filter to the pressure pump. PP 5mm filter in the inner filter cup must be regularly checked with the naked eye and replaced when heavily soiled.

The pressure pump pushes seawater through the RO membrane under high pressure of about 55 bar, this pressure will filter seawater into fresh water, recovery rate (30-40)%. When the pressure is> 65bar, the system will automatically stop to protect the membrane.

The collected finished water has TDS <400 ppm, if the finished water is salty, the system will automatically stop the machine and report an error.
