What is the difference between the EPA terms MACT and RACT?
I know acronyms stand for...
MACT = Maximum Achievable Control Technology and
RACT = Reasonably Achievable Control Technology
But practically, what is the difference to a plant owner/operator?
I am counting out Pressure due to changing densities.
Has anyone used the Resistance tape sensor from Consilium?

It looks like it would work with a Stillpipe to keep the foam and velocity off of it.
Thanks for all the help so far.
The tank is 25 ft diameter.
I found some info on Radar (Vega)that indicates that foam depth over a few inches could be a problem even for radar.
The mixing is done with pumps which cause the foaming.
If a standpipe would work, then why wouldn't a simple site glass? Maybe vent the top of the...
What would be the best method to measure the level in a tank which is:
Acid, strong, various types, varying density, etc.
Foaming present on top
Particulate/solids collecting at bottom
I am thinking Radar or Pressure, am I on the right track?
I have some questions about Air scouring of pipes for removal of scale, etc. Can anyone recommend a good description / reference for how to accomplish this? I gather that it is the injection of compressed air into the water supply to create more turbulence to loosen the crud off the pipes.
