Smart Raking™ and Smart Bar Screen™ provide additional hydraulic capacity and safety factor for maximum resiliency
A smarter way to screen
Today’s extreme weather conditions, changing populations, and new solids like flushable wipes, have added stress on plant operations. Peaking events are higher and more frequent than they have ever been. When planning, engineers must consider all the known (and account for unknown/changing) debris and flow variables. Design safety factors ensure the headworks can manage the highest possible flow, sometimes resulting in more infrastructure like extra units, bypass channels, oversized equipment, and coarser bar openings to handle these peaking events.
We asked ourselves, what if the headworks could be installed with the finest possible openings for normal flows and the screen itself adapted to peak events?
The answer? An intelligent screening system that knows what to do and when to do it.
INTRODUCING the FlexRake IQ2
a screening system that allows fine screening during normal conditions, then automatically transitions to a wider opening during peak conditions. The FlexRake IQ2 has all the enhanced raking features of the FlexRake IQ with the Smart Bar Screen™ upgrade for additional hydraulic capacity when it’s needed most.
Like the FlexRake IQ, the FlexRake IQ2 significantly improves solids handling by sensing conditions and speeding up to accommodate changing debris and flow. The reconfigured geometry of design allows for lowest possible engagement to better handle settled solids. Re-engineered scrapers are stronger and remove up to 4x more debris. The re-imagined FlexLink still manages large debris without jamming and now re-engages into the bar screen faster. For optimum performance under all conditions, the next-level FlexRake IQ2 intuitively transforms the bar screen to accommodate increased flow capacity…without operator intervention.
The FlexRake IQ2 provides additional resilience with TWO SCREENS IN ONE for the safety factor of a coarse screen combined with the debris capture of a fine screen… intuitively & automatically
- Screen at the finest bar opening during normal plant operations.
- Manage hydraulic and solids surges by adapting bar opening as flows demand more capacity
- Return to finest screen openings all without operator interface
The FlexRake IQ2: physically and operationally adapts for maximum resiliency over the broadest range of conditions.
- Pump stations
- Influent bar screens
- Municipal headworks
- Combined sewer overflow facilities
- Industrial applications
The FlexRake IQ2 includes all the Smart Raking™ benefits of the FlexRake IQ
Automated, real-time response
Intuitive Sequence of Operations optimizes screen field in changing flow and debris conditions
Increased debris removal
Up to 4x the debris removal capacity
Enhanced solids capture
Improved grit/rock handling and rapid re-engagement into the bar screen after removing large debris
The FlexRake IQ2 provides maximum resiliency for peak flow management with the Smart Bar Screen™:
Screens to the finest bar opening for normal operations and transforms to larger openings as required – matching the best capture rate for the flow rate in real-time
Additional throughput and safety factor during peak flow
40% increased hydraulic capacity when bar screen transforms to a wider opening
The screen field is monitored for constant optimization without operator intervention
Maintains screened flow
No process interruption with continuous cleaning during the open and close cycle between fine and larger openings
Upgrade existing sites to finer openings
May allow for finer openings on existing sites while accommodating peak flows
A new level of resiliency is required to meet today’s plant challenges and prepare for tomorrow’s unknowns. The FlexRake IQ Platform tackles high peaking factors due to extreme weather and menacing debris like “flushable” wipes, first flushes and settled solids. This is accomplished by system improvements and a patent-pending sequence of operations that automatically responds in real-time to optimize the screen field.
The re-imagined design of the FlexRake IQ focuses on smart enhancements to the raking device to manage heavy solids loading events with 4x increased debris removal capacity, improved grit and rock handling, and greater solids capture. During peak flow conditions, the FlexRake IQ2 adjusts the bar screen opening itself to provide additional hydraulic capacity and safety factor. Matching the best capture rate to the flow volume in real- time.
The FlexRake IQ Platform is an intelligent screening system that knows what to do, and more importantly when to do it without operator intervention.
