OLKLIN®-DRO-3
Cleaner
For Membrane Separation System
Introduction:
OLKLIN-DRO-3 is a low foaming liquid designed to remove silt and organic foulants such as colloidal silica, clays, organic colour and bacterial slime from thin film composite membranes. OLKLIN-DRO-3 is buffered to prevent the pH limits of a membrane being exceeded in the event of misapplication. OLKLIN-DRO-3 should not be used on cellulose acetate membranes, as irreversible damage can occur.
Instructions for Use:
For moderate to severe fouling, OLKLIN-DRO-3 should be applied at a nominalstrength 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 re-circulated at the flow rate recommendedby the membrane manufacturer, taking care not to exceed the guidelines forpressure.
Maxwell Additives recommend the following flow rates for cleaning spiral wound elements:-
| Element Diameter | Flow rate |
|---|---|
| 4" (100mm) | 40 lpm |
| 8" (200mm) | 150 lpm |
Temperature:
Where possible, apply the cleaning solution at the maximum temperature recommended by the membrane manufacturer.
Packaging:
OLKLIN-DRO-3 is available in 20kg carboys or 200kg drums. Other packaging is available on request.
Performance:
OLKLIN-DRO-3 offers a variety of performance benefits:
- Compatible with the major membrane suppliers.
- Superior results in the removal of organic and colloidal foulants, especially when compared to generic formulations.
- Contains a specialised blend of buffers and other components to dissolve organic foulants, and disperse colloidal particles.
- Highly buffered to resist pH changes during the cleaning process.
- Can be used in conjunction with other applicable cleaners.
Safety precautions:
