Description Non-Ragging Channel (NRC) Mixer NRC’s unique variable geometry custom designed for the widest range of wastewater velocities and channel depths found on a typical wastewater treatment plant The unique design provides many features: • Variable angle control vanes tuned to optimise performance within tight headloss constraints • Subsurface fixed vanes to aid mixing at low depth • Adaptable design for a wide range of channel sizes, aspect ratios, water depths and flow rates • No direct power requirements for mixing • Available with automatic (power required) or manual (no power required) control vane options • Accessible integrated sparger for chemical injection • Designed for easy installation into open channel • Custom designed for each application Key benefits include: • Significant chemical savings • Reduced BOD load • Reduced Fe concentration in final effluent/ sludge • Substantial cost savings • Improved primary sedimentation tank performance • Higher sludge concentrations • Reduced or eliminated channel staining
