Summary
Product identification
- Product Name: AWC® C-234
- Product Type: Reverse Osmosis Membrane Cleaning Compound
Advantages
- Concentrated liquid formulation designed for use as a low pH cleaner of polyamide thin film composite membrane surfaces.
- Removes inorganic carbonate, phosphate, and sulfate scalants as well as metal oxides.
- Contains a synergistic blend of cleaners and scale removal agents for a thorough cleaning of the membrane.
- Will remove certain inorganic precipitants that cannot be removed through the use of citric or hydrochloric acid.
- May eliminate the need for repeat cleanings in cases of severe scaling.
- Compatible with all Thin Film Composite R.O. membranes from all major membrane suppliers.
- Certified by NSF to NSF/ANSI Standard 60.
Typical Properties
- Appearance: Clear colorless to yellow liquid
- Odor: Essentially no odor
- Solubility in water: Complete
- pH (as is) @ 25˚C: < 2
- Specific Gravity: 1.15 ± 0.05
Chemical Feeding and Control
- The cleaning solution should be prepared using potable water that is free of residual chlorine or other oxidizing agents.
- Add 2 gallons of AWC C-234 to every 100 gallons of water (2% solution).
- Adjust the pH in the range 2–3.
- Recirculate the cleaning solution throughout the system, after redirecting the first 20% of the solution to drain.
- Do not exceed pressures, temperatures, and flow rates recommended by the membrane manufacturer.
- Cleaning efficacy can be further improved by heating the cleaning solution and alternately circulating the solution for 15 minutes and then soaking the membranes for 15 minutes. Repeat as necessary.
- Monitor the pH range periodically throughout the cleaning. When pH increases above the desired range, it should be adjusted by adding more AWC C-234.
Safety & Handling
- Store in cool, dry and well ventilated area.
- Keep containers closed.
- Wash contaminated clothes before re-use.
- Wash thoroughly after handling.
