RoClean L212

Summary

Product identification

RoClean L212 Green is a high pH, liquid cleaner formulated to remove silt and organic foulants from spiral wound polyamide membrane elements. It is EDTA and Phosphate Free.

The product is certified by NSF International under NSF/ANSI Standard 60 as an off-line cleaner in drinking water systems.

Operating limits

• pH (2% solution): 11.7-12.7
• Specific Gravity (@25°C): 1.1-1.2

Feed water

• Cleaning Solution Preparation:
  • Fill the cleaning tank with reverse osmosis (RO) permeate or deionized water.
  • Heat the solution to the maximum acceptable temperature according to membrane manufacturer guidelines.
  • Add RoClean L212 to create a 1% wt/wt solution for mild fouling or a 2% wt/wt solution for moderate to severe fouling.
  • Recirculate the solution for adequate mixing.

Product water

• Rinsing is completed by flushing RO permeate through each pressure vessel after cleaning.
