Non-foaming liquid formulation for high pH Chemically Enhanced Backwash (CEB) of ultrafiltration and microfiltration membranes

Advantages

  • Non-foaming liquid formulation for high pH Chemically Enhanced Backwash (CEB) of ultrafiltration and microfiltration membranes
  • Designed to inhibit metal oxide precipitation when MF/UF filtrate used for CEB contains high levels of dissolved manganese and/or iron
  • Works to reduce biofilm and organic foulant buildup between CIP’s
  • Buffered so as not to exceed a pH of 12
  • Compatible with all MF/UF modules that can tolerate pH 12
  • Certified by NSF to NSF/ANSI Standard 60 for use in potable systems

Typical Properties

  • Appearance: Clear, colorless to light yellow liquid
  • Odor: Slight characteristic odor
  • Solubility in water: Complete

Packaging

  • 5 gallon pails
  • 55 gallon non-returnable plastic drums
  • 275 gallon totes

Safety and Handling

Store in cool, dry and well ventilated area. Keep containers closed. Wash contaminated clothes before re-use. Wash thoroughly after handling. For more information, see the Safety Data Sheet provided with this product.

Chemical Feeding and Control

Always use MF/UF filtrate or RO permeate for CEB. Inject AWC UF-412CEB at a rate of 2% (w/w) into the backwash water flow during the CEB cycle. The CEB solution is typically allowed to soak for 5 – 30 minutes, with optional intermittent agitation (air sparging/circulation) for short periods (5 – 10 seconds) every 5 minutes. Warming the solution to 35°C will enhance the efficacy of foulant removal during CEB. The membranes are then flushed with MF/ UF filtrate prior to returning to normal filtration mode.
