Hi,
I bought the components to make myself a small RO system at the end of last year and have been experimenting with it with water (until the sap start running hopefully tomorrow ). My question is about how to clean my system as I plan on running the RO every couple days. 1. Between runs. 2. At the end of the season and 3. For preservation of membranes until the following season. After much reading, it looks like a 1% solution of SODIUM METABISULFITE should be used for long term storage (in the fridge). But looking at my online store of sugaring equipment, I also see CITRIC, CLEANER OXYSAN and MEMBRANE SOAP. Could anyone tell me when to use each and in what concentration?
Thanks
