aquaMAXTM-Basic 360 Series
1-4. Configuration
1-4-1. R.O. Membrane Pack and Prefilter(PRE PACK)
The Water supply(tap water or treated municipal water) is fed through a pre-filter to be separated large and small
particles by filtration. The permeate water then enters the RO Pack housing and permeates through the
spiral-wound RO membrane. For the Basic 360 Series, when RO membrane is pressurized at 5.5 Kg/cm2,
approximately 70% of the input water is continuously withdrawn from the system through a reject valve and the
remaining 30% of the water permeates through the membrane to be filtered. The productivity of RO membrane
is varied depending on pressure and used time.
1-4-2. Booster Pump
The booster pump of the Basic 360 Series is a silent diaphragm pump. It can transfer water flow rate of
maximum 60 liter/hour, however the purified water can be produced at maximum 10 liter/hour when supplied
with RO pressure of 5.5 Kg/cm2. The amount of the purified water can be varied by temperature, used time and
pressure of RO membrane.
1-4-3. Pressure Switch
If the inlet pressure of a water supply is less than 0.8 Kg/m2, the pressure switch automatically stops the
booster pump to prevent the pump from damage and if it is more than 7.0 Kg/cm2, it stops the operation to
prevent the filter from damage. The inlet pressure of water supply should be more than 1.0 Kg/cm2, because the
pressure drops down after passing through the prefilter. In case the switch stops the booster pump at low
pressure (less than 0.8 Kg/m2), you should raise the inlet pressure first to drive the booster pump again.
※It is required to install an extra external pump if the pressure of water supply is less than average 0.8 Kg/m2..
1-4-4. Drain Valve and Automatic Flushing
The drain valve consisted of a needle valve and a solenoid valve is designed to control the backpressure of RO
membrane. The reverse osmosis is displayed on the pressure gauge mounted inside of the system. The Basic
360 Series automatically turns on the drain valve every 30 minutes for 1 minute so that the contaminants
collected on the RO membrane surface can be flushed away by a high velocity flush of water.
1-4-5. Water Quality Monitoring
The Basic 360 Series monitors water quality by measuring conductivity at 3 different points. The measured
value indicates ion drain ratio and time of filter replacement.
