Summary
Product Identification
- Product Name: AWC® UF-426
- Product Type: MF/UF Membrane Cleaning Compound
Advantages
- High strength powder formulation designed as a high pH cleaner for microfiltration and ultrafiltration membranes.
- Effectively penetrates and lifts biofilms, organic foulants, oils, greases, and other hydrocarbons from the membrane surface.
- Disperses inorganic particulates such as silts, clays, and metal oxides.
- Designed for use with membranes tolerant to cleaning at pH > 10.
- Compatible with most MF/UF modules.
- Certified by NSF to NSF/ANSI Standard 60.
Typical Properties
- Appearance: White to tan powder
- Odor: Characteristic
- Solubility in water: Soluble
- pH (1% solution): > 11.5
Chemical Feeding and Control
- Water for solution preparation: Potable water free of residual chlorine or other oxidizing agents (RO permeate or DI water preferred). Do not use hard water.
- Concentration: 10-20 lbs of AWC UF-426 for every 100 gallons of water (~1–2.5 wt% solution), depending on fouling severity.
- Temperature: Heat water to maximum temperature allowed by module manufacturer.
- Cleaning Procedure:
- Circulate cleaning solution through modules with filtrate valve closed, in the feed direction for 30 minutes (for tubular designs).
- Reverse direction of flow; recirculate for another 30 minutes.
- Add more AWC UF-426 to maintain pH between 11–12 throughout the cleaning process.
- Repeat as necessary until pH remains stable for two consecutive readings, without exceeding the membrane manufacturer’s recommended exposure time to high pH cleaners.
- For systems allowing back flushing, back flush with cleaning solution from filtrate to feed for 15 minutes.
- After cleaning, flush modules with MF/UF filtrate.
Safety & Handling
- Store in a cool, dry, and well-ventilated area.
- Keep containers closed.
- Wash contaminated clothes before re-use.
- Wash thoroughly after handling.
- Refer to the Safety Data Sheet for more information.
Packaging
- 50 lb. pails
- 400 lb. non-returnable plastic drums
