Avista™ | OSCAR Off-Site Cleaning and Restoration
Avista™ OSCAR off-site cleaning and restoration is available when cleaning on-site is not practical or possible. Reverse osmosis (RO) membranes are pre-tested, cleaned, and post-tested with the goal of restoring performance to original factory specifications. Avista™ OSCAR off-site cleaning and restoration uses equipment specifically designed to provide ideal flow rates, water temperature, and cleaning pressures.
- Cleaned elements are heat-sealed in a poly bag and packaged in a new box for transport
- Pre- and post-test data is returned with every order so that operators can see not only the results of the clean, but also select specific membranes for re-installment based on specific performance parameters
- Physically inspect each element
- Initial Element Wet Test Results
- Element Cleaning
- Element Post-Test
- Element Preservation
Oscar Case Study
SITUATION
A large northwest United States computer manufacturing company has been cleaning membranes for their UPW RO process using OSCAR services at Avista Technologies since 2010. Interesting facts for this story are that these membranes have traveled to-and-from New York 8 times in the past 10 years covering 43,200 miles via inland freight. During this time frame these membranes have not been replaced and are performing to the manufacturer’s spec since 2010. This confirms that one can clean and transport membranes for detailed pre and post-cleaning analysis to exceed the average membrane life of 3 to 5 years. This confirms that membranes can be cleaned and transported for detailed pre- and post-cleaning analysis and successfully exceed the average membrane life of 3 to 5 years.
- These membranes have traveled to-and-from New York 8 times in the past 10 years covering 43,200 miles via inland freight.
- During this time, these membranes have not been replaced and are performing to the manufacturer’s spec since 2010. 2017: 6.8 gpm, 99.0% 2016: 6.7 gpm, 99.8% 2015: 6.9 gpm, 99.2% 2014: 6.8 gpm, 99.6% 2013: 7.0
SOLUTION
This confirms that membranes can be cleaned and transported for detailed pre- and post-cleaning analysis and successfully exceed the average membrane life of 3 to 5 years.
