8  RO MEMBRANE CLEANING 

 

8.1  GENERAL 

 
The RO membranes fitted to the ORION unit should be cleaned if they become fouled or scaled and 
the permeate flow from the RO system falls. 
 
The flow of permeate from an RO system is dependent on a number of operating parameters 
principally, applied pressure, temperature and the osmotic pressure of the water being purified.  
These factors need to be taken into account when assessing whether membranes require cleaning 
and this is achieved 

by calculating the “corrected flux” for the plant which takes these factors into 

account. 
 
Corrected Flux is the flow of permeate per square meter of membrane area corrected for 
temperature, pressure and osmotic pressure. 
 
The ORION PLC calculates corrected flux on a continuous basis and advises when cleaning is 
required, i.e. when the corrected flux falls below 90% of the previously accepted “clean flux”.  This is 
indicated by a non fatal alarm and the HMI RO screen. 
 
The following chemicals are recommended for use with ORION systems. 
 

 

Solution (A) - Acid Cleaning Solution

 

 
Properly operated RO systems should not require acid cleaning. Precipitation can, however, 
occur when the plant is operated at high recovery or on pre-treatment failure. 
 
In such cases Elgalite RU3, which is an acidic cleaner, will remove calcium and magnesium scale 
from the membrane. It is also effective in removing iron which can be present in feed water. 
 
Elgalite RU3 is available in boxes containing 12 x 1.5kg bottles (Veolia Water part number 
CHEGRO0083) and is used at the rate of 1.5kg, ORION 500 

– 2000 and 3kg, ORION 4000 - 

6000. 
It is also available in 8kg drums Veolia part number CHEGRO0084 and is used at the rate of 8kg 
for Orion 8000 - 10000 

 

 

Solution (B) - Alkaline Cleaning Solution

 

 
An alkaline detergent is recommended for the removal of biological material, colloids, silica etc, 
from the surface of the membranes.  Elgalite LF12 is a combined alkaline powder detergent 
formulated to remove the majority of foulants normally encountered in water treatment systems. 
 
Elgalite LF12 is available in boxes containing 10 x 1kg pails (Veolia Water part number 
CHEGRO0058) and is used at the rate of 2kg, ORION 500 

– 2000 and 4kg, ORION 3000 – 5000 

and 8kg Orion 8000 

– 10000.
