Hi:
I used this air/water wash tile with IMS cap many years ago in a 43 usmgd wate plant I designed 15 years ago very successfully in the Toronto area. We did separate air scour washes. The double orifice arrangement spreads out the air and water throughout the filter bed
There are companies out there right now that are promoting simultaneous air scour/water wash. I have not heard good stories and I would check it out thoroughly before considering them.
Having a separate air header laid on top of the filter requries the air flow in each of the drop legs to be balanced
