Egger Iris Valves for stable flow control at WWTP Baltimore Backriver
174 Iris Diaphragm Control Valves are in operation at the Waste Water Treatment Backriver in Baltimore, USA. The unique Iris® Valve has a large, stable control range and low pressure losses, ideal for energy savings with the blower control of the aeration tanks.
First there was Fine Bubble Diffusers, next High Speed Turbo Blowers, then Hyperboloid Mixer technology, and finally the Iris valve completes your system for fast, efficient, and accurate process control.
In 2013; Baltimore Back River began installing 174 Iris valves, Rotork Actuators, and ABB “Sensyflow” thermal mass flow meters. Egger’s “Air Flow Control” System was part of an overall process upgrade which included new high speed Turbo blowers & Hyperboloid mixers.
Our valves are a necessary “Appurtenance” for the blower systems overall performance providing stable valve position feedback for the SCADA system.
Stable, Linear, Accurate, Repeatable, and Reliable air flow control to improve your process and reduce air usage. Iris valves are the Next Technology Revolution in Wastewater treatment!
