Statiflo Non-Ragging Static Channel Mixer (NRC)
A non-ragging static channel mixer for dosing additives into wastewater including raw sewage. The Statiflo NRC Mixer has been designed specifically for P removal applications but can equally be used on any chemical dosing service on raw sewage where non-ragging properties are essential. It has a unique variable geometry custom designed for the widest range of wastewater velocities and channel depths found on a typical wastewater treatment plant.

Statiflo NRC Mixers have been installed since 2008 and have consistently remained rag free and have required no maintenance.
The mixer’s non-ragging design features:
- Variable angle control vanes tuned to optimise performance within tight headloss constraints
- Manual or automatic (power required) control vane options
- Integral accessible sparger for chemical injection
- Subsurface fixed vanes to boost mixing at low depth
- Designed for easy installation in live open channels
- Design adaptable for a wide range of channel sizes, aspect ratios, water depths and flowrates
- No direct power requirements for mixing
Upgrading from commonly occurring dosing, using an open ended pipe, to a Statiflo NRC Mixer will provide many process benefits:
- Very significant chemical savings
- Improved primary sedimentation tank performance
- Reduced BOD load
- Higher sludge concentrations
- Reduced Fe concentration in final effluent / sludge
- Reduced or eliminated channel staining
- Substantial cost savings
