Returning filter membranes to full flux, even with difficult biofouling or complex,mixed foulant residues requires Alconox filter membrane cleaners.
From the early days of filter membrane development, Alconox cleaners have been there to provide compatible, reliable cleaning on even the most difficult filter foulants.
- TERG-A-ZYME: enzyme active bio-fouling cleaner
- CITRANOX: enhanced citric cleaner for difficult scales and silts
- ALCONOX: restores flow rates without hazardous caustics
- CITRAJET: low foaming enhanced citric cleaner for difficult scales and silts
|
 |
Before: Reverse osmosis membranes must be cleaned to yield required flowthrough rates - without contaminating food products.
After: After cleaning with TERG-A-ZYME brand, diaphragm shows required drop in pressure differential - without an increase in the permeation flow. |
