Before: Reverse osmosis membranes must be cleaned to yield required flow through rates – without contaminating food products.

After: After cleaning with Tergazyme brand, diaphragm shows required drop in pressure differential – without an increase in the permeation flow.

 

 


Returning filter membranes to full flux, even with difficult biofouling or complex, mixed foulant residues requires Alconox filter cleaners for reverse osmosis (RO) and ultrafiltration (UF) membrane and module filter cleaning.

From the early days of filter membrane development, Alconox filter cleaners have been there to provide compatible and reliable cleaning on even the most difficult filter foulants.

  • Alconox: Restores flow rates without hazardous caustics.
  • Citrajet: Low-foaming enhanced citric cleaner for difficult scales and silts.
  • Citranox: Enhanced citric cleaner for difficult scales and silts during filter cleaning.
  • Tergazyme: Enzyme active biofouling filter cleaner.

Recommended Cleaners

* Adjust pH with Citric Acid to membrane manufacturer tolerances.
** Check with membrane manufacturer for approval.
Approved membrane configurations are: Disc & Tube, Spiral Wound, Plate & Frame and Tubular styles.
RO = Reverse Osmosis, UF = Ultrafiltration, NF = Nanofiltration, MF = Microfiltration
