Safely Store Your Membranes For 6+ Months

Marine watermaker desalinator membranes

Why maintain reverse osmosis watermaker membranes?
When the desalinator is not used regularly, the membranes foul due to the decomposing mineral and biological residue left sitting inside. This is especially a risk during the winter months and other long periods of non-use.

How do I keep my membranes from becoming foul?
While the best method to keep your desalinator clean is to use it daily, another method—besides periodically cleaning it—is to store the membranes in a pickling solution. The Hope Group offers R.O. Membrane Element Pickling and Storage options that inhibit bacterial growth while maintaining the high flux and salt rejection of the R.O. Membrane Element.

How does the Pickling & Storage program work?
Our team will do an initial bench test to determine the current life of your R.O. Membrane element, flush, and pickle your membrane for the winter months. Before returning your R.O. Membrane Element our team will flush and bench test to determine the life left in the R.O. Membrane Element.**
