MEMBRANE CLEANING PROCEDURE 

 

The ECHO Tec. Watermaker must be chemically cleaned when the product water output drops by 15% 
of the specified amount.  The frequency of this occurring will vary greatly depending upon feed water. 
Fouling  of  the  membrane  will  naturally  occur  during  normal  usage  of  the  ECHO  Tec.  Watermaker.  
Increased amounts of fouling without proper cleaning of the membrane will reduce the performance of 
your water maker.  A drop in production of approximately 10% is normal and expected during the first 
year. 
 
Please  note  that  high  salinity  (over  500  TDS  ppm)  caused  by  biological  growth,  contact  with 
chlorinated water or other chemicals or the age of the membrane cannot be regenerated. 
 

CAUTION:  The use of chemicals or cleaning methods other than those outlined in the cleaning 
instructions will void the ECHO Tec. warranty. Nonionic surfactants for membrane cleaning or 
other chemicals not approved in writing by Echo Marine Ltd. will void the element warranty. 
 
CAUTION:    Cleaning  chemical  #1  is  an  alkaline  detergent.    See  warning  label  on  side  of  the 
container and observe all safety precautions on label. 
 
CAUTION:  Cleaning chemical #2 is an acid, a mineral scale remover.  See warning label on side 
of container and observe all safety precautions on label. 
 
CAUTION:    Do  not  mix  different  cleaning  chemicals  together.    Do  not  use  different  cleaning 
chemicals  together  at  the  same  time.    Mix  the  cleaning  chemicals  separately  and  use  them 
separately. 
 
Note:   

All  cleaning  and  preserving  procedures  can  be  done  with  either  seawater  or  non-chlorinated 

freshwater.  However, the cleaning process is more effective using non-chlorinated freshwater. 
 
 
To clean the ECHO Tec. reverse osmosis membrane mix a solution of 1.5 to 2% by weight with warm 
non-chlorinated water (113° F / 45° C) in a clean plastic container.   
Use 10ltr. / 2.5gal (with 200g / 2/3 container cleaning agent) for one 40” membrane and 4ltr/1gal (with 
40g cleaning agent) for every additional membrane. 
 
For safety reasons we do not recommend to install a 3 way re-circulating valve.  Disconnect the intake 
and reject water hose and lead them in the plastic container.  Re-circulate the solution 

without pressure 

for up to 60 min.  There will be no flow at the fresh water outlet. 

 
CAUTION:  Observe the maximum operating temperature of 113° F / 45° C.  The high pressure 
pump might over heat the solution on re-circulating.   

 
It  is  important  that  the  fresh  water,  remaining  from  the  last  flush  is  dumped    (about  4  ltr.  /1gal.  per 
membrane) before the reject hose is led in the cleaning bucket for re-circulation.  This will avoid that 
fresh water dilutes the cleaning solution. 
 
Use cleaning chemical #1 first.  If the performance does not improve use the acid cleaner #2 at the same 
ratio and instruction.
