Statiflo International Ltd.

- Non-Ragging Pipe Mixer (NR)



The Statiflo NR Pipe Mixer has been specifically designed for sludge mixing or wastewater applications with high fibre content.

In full-scale trials with a major UK water utility the Statiflo NR Pipe Mixer outperformed all competitor’s designs including a static mixer, an orifice plate and sludge valves.

These pictures and graphs illustrate the superior performance of the Statiflo NR Mixer compared with a competitor’s mixer.  The graph  shows the typical effects of ragging with increasing headloss and reduced flow until the competitor’s mixer ceased to operate in less than four hours.

In comparison the Statiflo NR Mixer elements remain clean and free flowing indicated by the consistent headloss performance.

The Statiflo NR Mixer is proven to be suitable for the following applications:

  • Sludge blending
  • Sludge thickening
  • Ferric sulphate and ferric chloride dosing for phosphorous removal
  • Coagulant / polymer dosing
  • Chemical dosing of sewage
  • Industrial wastewater treatment with fibres including paperstock

The Statiflo NR Mixer’s unique mixing element design provide:

  • High performance mixing low CoV

  • Consistent mixture quality
  • Low pressure drop
  • Easy to clean
