Folded Flow® DAF Separator

In 1999 the Water Environment Federation (WEF) awarded its Innovative Technology Award for Process Equipment to USFilter, Envirex Products for the Folded Flow® DAF separator. This technology is one of the truly ground-breaking improvements to this 50+ year- old process.

This innovation dramatically improves the hydraulic performance of DAF separator tanks which:

• Allows 2-3x increase in hydraulic loading than conventional systems
  
• Smaller, modular systems require only 1/3-1/2 the space of old designs and provide superior performance.
  
• Smaller equipment footprint.
  
• Lower capital, installation, and operating costs through process optimization.
  
• Reduced or eliminated requirement for equalization.
  
• Average flow design can treat process upsets effectively at 2-3 times average flow and loading.

Two paper mills contracted Envirex Products to retrofit existing DAF's to Folded Flow hydraulics to stay in compliance of discharge permits during process peaks and upsets.

Key markets for Folded Flow® DAF processes are:

• Pulp and Paper (four installations ranging from effluent polishing to process water recycle)
  
• Hydrocarbon Processing Industry (oily water clarification)
  
• Railroad (oily water clarification)
  
• Municipal (primary clarification)

USFilter, Envirex Products has Folded Flow® separator installations in the Food and Beverage, Manufacturing and Surface Water Treatment arenas as well. We strongly encourage you to keep Folded Flow® DAF separation in mind when searching for the superior and optimal process in these markets. It is recognized as one of our best products and has given us an optimistic outlook for the growth and development of our industrial equipment sales.
