Troubleshooting
Product amount of water too low.
Membrane is blocked or defect.
Temperature seawater lower than 25 ° Celsius.
Salinity seawater higher than 35,000 ppm.
Reduced sea water flow because of blocked or dirty filters.
Insufficient fresh water rinsing after every use.
Insufficient chlorine separation by the charcoal filter, assuming chlorine is or was present in the
rinsing tank, chemicals or oil sucked in.
HP pump: dirty or defective valve.
HP pumps insufficient performance.
Low voltage.
Check voltage at connections of motor high pressure pump, motor
protection switch, fuses and all connections up to power supply.
Current consumption according
to specification too low?
Probably dirty or defective valve.
Control of HP pump’s performance.
Current consumption consistent with specification OK?
Recommendation: accurate test of the HP pump output:
Instruction for testing the flow (liter/minute) of the HP pump.
1) Place the plant into operation.
2) Adjust the working pressure.
3) Turn the 3-way valve No: 4 to operate toward the 5 or 10-liter conservation tank.
4) Alternatively, pipe seawater concentrates into a bucket to measure the quantity.
5) Using a stop-watch, to measure the time until filling. In order to avoid an overflow,
strictly reposition the valve to the board setting shortly before the tank is full.
6) In addition, collect the amount of product water in the same period of time over the test
outlet in a vessel and add it.
HP pump performance in liters per minute at 55 bar working pressure:
AC 65- 110: 5,7 litre/ minute, AC 75- 135: 10 litre/ minute,
AC 150- 240: 13 litre/ minute
AC 190- 240 – Motor 2,2 KW: 14,5 litre/minute
Attention!
The drinking water production changes according to the salinity, the temperature of the
seawater and the age of the R.O. membrane. The data regarding the fresh water
production apply to a salinity of 35 grams/ litre at a temperature of 25º Celsius (77°
Fahrenheit) at the new membrane.
A discrepancy up to +/- 10% also in the power consumption, especially in the first 50
hours of operation, are usual.
At seawater temperatures below 25° C, the product water quantity is reduced by the following values. Data
(approx.) In %.
Water temperature 15° C - 20% Water temperature 5° C - 35%
