Aeration Air Flow Control (AFC) SYSTEM
Aeration Air Flow Control (AFC) SYSTEM
Simply mount our engineered 304 stainless steel Air Flow Control System that includes flanges, reducers, 10 pipe diameters of straight pipe, reliable Sensyflow Thermal Mass Flow Meter mounted in a service friendly “hot tap”, 1 pipe diameter straight length to the Iris valve mounted complete with high performance electric actuator.
DO Based Aeration Control with diffused aeration and blowers. Iris Valve Process Control for:
- Airflow based control
- Pressure based control
- Most Open Valve automated control types
- Ammonia-Based Aeration Control (ABAC)
Features
Iris® flow control valves are characterized by flow which is always centered. The passage can be varied continuously, similar to a camera aperture. Thus, constant flow rates may be reproduced in any position. The ideal control characteristic according to DIN EN 60534 and its low pressure losses make the Iris® control valve a reference to an energy-saving valve in many industries. Here is a small selection of typical applications.
High-Performance Valve
Available Sizes: 1″ – 16″
Pressure: up to 87 psi higher upon request
Temperature: up to 248 higher upon request
Aeration in a wastewater treatment plant
Used to regulate the aeration, this valve has been proven thousands of times at wastewater treatment plants. Due to the enormous energy saving, Iris® diaphragm control valves recover cost rapidly in wastewater treatment plants. In combination with a Kurz model 410FTB Thermal Mass Flow Meters, cascade regulation with slave loop according to ATW can be assured.
ABAC / Ammonia-based aeration control
Ammonia-based aeration control (ABAC) is a cascade control concept for controlling total ammonia nitrogen (NHx-N) in the activated sludge process. The Iris valve offers a broad range of stable air flow control from 15% to 94% which makes it ideal for ammonia based aeration control.
