Storage Procedures (Pickling)

Propylene glycol can be used instead of Spectra SC-1 storage chemical for storage in any climate, and treatment is effective for one year. Propylene glycol is a food-grade antifreeze used to winterize RV's, boats, and cabins. Do not use ethylene glycol automotive antifreeze, which is toxic and will damage the system. Be advised that many off the shelf potable water antifreeze propylene glycol formulations contain ethyl alcohol as an additive, which is harmful and will attack the plastics used i...

You can use Spectra SC-1 as a pickling/storage solution to keep the system growth free for 6 months. Propylene Glycol is used to keep the system growth free for up to one year, as well as offers some extra weather protection. Additional details are below. SC-1 prevents biological growth when your system sits idle. It should not be used as a cleaning chemical, nor will it protect your system from freezing. An 8 oz. bag of SC-1 is mixed with product or dechlorinated fresh water and circulated ...

Biological Growth/Membrane Lifespan The element in the system that performs the water purification is the Reverse Osmosis Membrane. The synthetic membrane is highly susceptible to bacterial growth. It will be evident that bacterial growth occurred if the freshwater from the unit smells like rotten eggs. Regular freshwater flushes and attention to detail with membrane maintenance will keep your membranes in optimal condition. For our energy recovery based systems, on average you can expect about...
