OVIVO | NUTRIENT REMOVAL

CARROUSEL® SYSTEMS

MAXIMUM TREATMENT – MINIMUM EFFORT

HOW IT CAN MEET YOUR NEEDS:• Meets the Most Stringent Effluent Requirements• Simple to Operate and Easy to Maintain• Eliminate Chemical Dependency• Reduce Energy Use• Proven Technology – 700+ U.S. installations

2014 Current Ditch Technology

The AlternatIR™ System:

• Dual Impeller Aerators• More Turndown (85-90%)• Better Mixing & Velocity• Protects process (no over-aeration)

• Automatically Controlled Internal Recycle Gate• Optimized Denitrification• Bio-P without dedicated Anaerobic Selectors (TP<1.0 mg/l)

• Auto Open/Close cycling has been proven to create anaerobic conditions enough for PAO’s to thrive

• Oculus Control System• D.O. Control• Energy Optimization• Gate Control• BNR Optimization• Mixer Monitoring• Can be MCC or stand-alone panel

IR Gate Control Makes a Difference

• Before Gate Control• TN = ~9-11 mg/l

• After Gate Control• TN < ~4-5 mg/l

• Improves Nitrogen AND Phosphorus Removal

ORP fluctuates -275 to -90.

ORP Stable at Set Point For Optimal BNR
