FUNCTIONAL 
DESCRIPTION 

 

The water is pressed through the 
RO  membrane  by  means  of  a 
high-pressure  pump.  The  per-
meate  (desalinated  water)  is 
then led to consumption and can 
e.g.  be  collected  in  a  reservoir. 
The  concentrate  (the  water  con-
taining the concentrated salts) is 
led  to  outlet.  The  relation  be-
tween  permeate/  concentrate 
shall  be  adjusted  manually  on 
the needle valve. 
Under  normal  operating  condi-
tions the RO membranes have a 
long  lifetime.  But  even  with  a 
good  feed  water  quality,  layers 
of  impurities  will,  to  a  certain 
extent, occur and there will be a 
slow  reduction  of  the  permeate 
capacity.

REPLACEMENT OF 
MEMBRANES 

 

Read  this  chapter  before  dis-
mounting/replacing  the  mem-
branes. 
Turn  off  the  power  and  discon-
nect the water to the plant. 
Dismount  the  U-lock  placed  at 
the  top  of  the  membrane  pipe. 
(the  U-lock  keep  the  membrane 
bottom in place). 
Remove  the  pin  in  the  U-lock 
and pull the lock out of the pipe. 
The  end  plates  can  now  be 
pulled  out  of  the  membrane 

pipe by wriggling the end plates 
from side to side and simultane-
ously pull upwards.  

 

Note!  it  may  be  necessary  to 
use a puller to get the end plates 
out  of  the  membrane  pipe.  Or-
der a puller for a 4" membrane 
pipe from your usual supplier or 
from BWT. 
The  membrane  can  now  be 
pulled  out  of  the  membrane 
pipe.  
Note!  at  which  end  the  big, 
black 

V-cup seal

, located on the 

outside  of  the  membrane  is 
placed.  When  the  new  mem-
brane  is  to  be  fitted,  this 

V-cup 

seal 

must  be  fitted  at  the  same 

end  of  the  membrane  as  the 
former one, i.e. if the 

V-cup seal 

is  located  at  the  top  of  the 
membrane  pipe,  then  the  new 
membrane 

V-cup  seal 

shall  also 

be  placed  in  that  way,  so  that 
the 

V-cup  seal 

is  located  at  the 

top when the membrane is refit-
ted in the membrane pipe. 
When all connections have been 
refitted  and  the  end  plates  se-
curely  fastened  with  the  U-lock, 
then the plant must be started up 
again. 
Re-connect raw water. 
Open the outlet valve completely 
and close the recirculation valve 
completely(section  13.7,  pos. 
1). 
Lead  the  permeate  hose  to 
drain. 
Reconnect power to the plant. 

The plant will now be in opera-
tion.  Let  the  plant  flush  in  this 
way for 20-30 minutes. 
Then  adjust  he  outlet  valve  and 
the recirculation valve. 
Check  the  plant  operating  pres-
sure on the manometer. 
Check that the water quality is  
<20  µS/cm.  This  can  be 
checked  on  the  permeate  hose 
(conductivity  meter  is  optional 
equipment). Lead the  hose back 
to  the  reservoir  (option),  when 
the quality is satisfactory. 
Check on the flow meter that the 
plant  capacity  is  satisfactory. 
The  plant  is  now  in  normal  op-
eration and ready for use. 
 
Make  notes  in  the  operating 
journal: 
 
1. Date of replacement of 
    membranes 
2. New capacity on the plant, 

flow meter FI1 and FI2 (13.7 
Spare parts drawing Pos. 8) 

3. Water quality, conductivity 
     meter (option) 
4. Plant operating pressure,  
    Manometer PI1 (13.7 Spare 
    Parts drawing, Pos. 4) 
5. Feed water temperature 
6. Feed water pressure
