Hydranautics Frequently Asked Questions
Can Hydranautics reverse osmosis membrane elements be cleaned with reverse direction cleaning?
Historically, Clean-in-Place (CIP) systems were designed to clean RO systems in a manner mirroring the regular operation, where the cleaning solution enters the feed end of the pressure vessels, passes through the RO elements, and exits at the reject end. This approach is generally effective and widely practiced. However, there are instances where reversing the cleaning flow direction has proven advantageous. Specifically, in cases involving substantial biological, colloidal, or particulate fouling, the fouling material can become highly concentrated at the feed end of the lead (or front) element. See Hydanautics technical service bulletin for more details.
What is the storage life for Hydranautics RO membranes and how should they be stored?
Before undertaking any long-term or short-term storage operation, contact Hydranautics for specific instructions related to the local environment. Learn more about general storage produceds for RO/NF membrane elements.
How much do Hydranautics RO membrane elements cost?
Hydranautics RO membranes generally cost between $300 and $800, depending on the filtration capacity in gallons per day (GPD). If you have questions about which membrane is right for your application, please call us at 877-377-9876. We're available Monday through Friday, 8 am to 5 pm Central Time.
