OLKLIN-DRO-2 is a low pH liquid cleaner designed to remove metal foulants such as iron, manganese, and aluminium as well as calcium carbonate scale deposits from thin film composite membranes. OLKLIN-DRO-2 is buffered to prevent the pH limits of a membrane being exceeded in the event of misapplication.
For moderate to severe fouling, OLKLIN-DRO-2 should be applied at a nominal strength of 2%w/v. For milder fouling, or where frequent cleaning is employed, satisfactory results may be achieved at 1% w/v.
The cleaning solution should be recirculated at the flow rate recommended by the membrane manufacturer, taking care not to exceed the guidelines for pressure.
Manhar Specialities recommend the following flow rates for cleaning spiral wound elements:-
Where possible, apply the cleaning solution at the maximum temperature recommended by the membrane manufacturer.
OLKLIN-DRO-2 is available in 20kg carboys and 200kg drums. Other packaging is available on request.
