RO Membrane Cleaning Service
High-quality demands and fast-paced production increase operational demands on membrane filtration systems. Regular servicing, optimization and on-site RO membrane cleaning service cycles can remove much of the daily fouling and keep reverse osmosis membranes working, however, more severe fouling can occur over time, requiring longer soak times, the use of more aggressive cleaning chemicals and occasionally, a membrane integrity test and investigation to understand the root cause of elevated fouling levels.
Fouling and scaling can cause long-lasting, irreversible RO membrane damage when left untreated, leading to performance issues, process downtime, and shorten membrane life. But, with increasing production schedules, limited space and the lack of specialized equipment, many businesses struggle to complete the proper level of RO membrane cleaning on-site.
That’s where Envirogen can help. Our off-site reverse osmosis membrane cleaning centers perform more rigorous cleaning, complete with pre cleaning and post cleaning membrane testing to ensure the membrane is returned as close to its original specifications as possible. A report is provided showing the extent of improved performance after RO membrane cleaning. The service can include preservative, vacuum sealed bagging, and boxing if specified.
Example of a fouled reverse osmosis spiral wound membrane
Our RO membrane cleaning service method is highly effective as it utilizes a 2-membrane vessel cleaning skid to reduce downstream elements. This approach is significantly more efficient than 5-6 membrane vessels used in normal clean-in-place (CIP) cleaning.
We offer comprehensive testing, alongside RO membrane cleaning service of the following water treatment and filtration membranes:
- 8” Ultrafiltration spiral wound membranes
- 8” Nanofiltration spiral wound membranes
- 8” Reverse osmosis spiral wound membranes
Our comprehensive chemical and physical RO membrane cleaning procedures remove the following contaminants:
- Scale – including calcium carbonate, sulphates and silica
- Colloidal contaminants – humic acids, fulvic acids and clays
- Particulates – including sand, carbon fines and breakdown materials from system components
- Biological contaminants
