I'm looking at getting a old but unused watermaker
. A Katadyn
PUR Survivor 35.
They have been in storage
for a number of years without their periodic (annual) Biocide treatment. Hoses have a discolouration and perhaps biocide crystallisation, which is to be expected from long-term storage
Now, can anyone tell me if they have managed to successfully revive a unused watermaker
that has been in storage?
I will be buying
a replacement membrane anyway, but am interested first if there is a possibility that it would work
straight from the box?
What procedure would you follow to try and get this working again without replacing the membrane? Would you flush first with biocide, non-clorinated water
, sea water
There is also a membrane cleaning
method using alkaline and/or acid. The alkaline cleaner is best for removing organic materials. The process is much like treating a sink drain with caustic soda (sodium hydroxide), a strong alkaline chemical. The alkaline cleaner dissolves and loosens organic matter, thus enabling it to be flushed out of the system. The acid cleaner is less commonly needed. It is useful for removing mineral deposits and scaling, which may occur when processing input water with unusually high concentrations of minerals.
Look forward to your thoughts?
