Have just taken my ro membrane out the housing unit and it's looking pretty clogged up does this look finished its about a year old meant to be hf4 4040 low pressure membrane but not been using it with booster pump coz booster pump broke

Do you ever backflush the ro?
-
Do you use filters? :o

What is it producing tds wise ?
Tds in ?
Tds out ?
Matters not what the thing looks like

Yes I did backwash it but for quite a long time I needed a new numpty to change the water flow so obviously built up got a new one ow setting it up tmoz with new booster pump so fingers crossed back producing pure with a good flow of water
-
Do you use filters? :o
Possibly need to replace my pre filters from ionics they do say 300000 litres of water so over years it's prob time to replace them
-
Are you saying that you've had the same pre-filters installed for a year? If so, that's likely the problem - the membrane wrecked due to pre-filters not being changed frequently enough.
I change the sediment and carbon pre-filters three time a year, though occasionally it goes to five months. These are 20". If using 10" ones, they will need a more frequent change. I'm a sole trader. I have low water pressure (35-40 PSI). I use the low pressure 4040. I do not use a booster pump. I turn waste on full flow for a minimum of 15 minutes per week, sometimes twice per week. So far, the membrane has lasted about 5 years. TDS 200 in, 008-012 out, depending whether or not I allow plenty of waste. The only down side is that the pure has lowish production for such a membrane, but it's plenty for me (60 - 100 litres of pure per hour).

I take it you are using a ionic pro series wfp van mount then?
I know of a few that have had issues with membranes not lasting very long with ionic van mounts. Not to mention the cost of replacement filter tubes, di tubes, replacement membranes, salt for backwashes etc all seems very expensive to me . Ionics must be making a killing ???
