I have just bought a Pur Powersurvivor 35 secondhand. I have limited information about the last time it was used and or pickled, probably 3-4 yrs ago. I have the manual and will contact the local Katadyn rep for advice/parts/chemicals but I would be interested in comments from experienced watermaker users as to their cleaning history and whether there is any chance the membrane can be resuscitated.
After trawling the www I read that:
- a chemical often used for 'pickling' is Sodium Metabisulfite - any confirmation or alternatives?
- Cleaning/flushing the system/membrane to return freshwater production to normal levels is done with an alkali solution for biological fouling and an acid solution for scaling - I can't find any information about what chemical and what strength. Can anyone tell me more?
