Talk:Large-scale trickle filters

This is a merger of two Wikipedia articles

This is a merger of the "Trickling filter" and the "Rotating biological contactor" article in Wikipedia. I was a major contributor (but not the original author) of those two articles. However, I have completely merged and re-written those articles to create this CZ article.

I have deliberately chosen to focus this CZ article on large-scale trickle filters so as to exclude small, onsite trickle filters used for rural residences and very much smaller yet trickle filters used for pet fish aquariums. Those smaller units would best be the subject of other CZ articles. Milton Beychok 18:08, 17 April 2008 (CDT)

Nice article. Presumably, as well as aquaria, it excludes economic theories of the Reagan Administration?

Apropos of small systems, I actually may be starting some actual control systems for home and small-restaurant-scale culinary herb greenhouses (possibly hydroponic). While my focus is more on the computer side, I might well have some starting points for articles. One of the interesting issues is finding inexpensive carbon dioxide sensors, which is also an issue in medicine. The low end on gaseous sensors appear to be dual-wavelength nondispersive infrared, but there has been some recent research on semiconductors that contain biologically active acceptors. Howard C.

I assume you are talking about "trickle down economics" or so-called "supply side economics". Nope, not covered in this article. As for carbon dioxide sensors, I really know nothing about them so I really can't help you with that. Good luck with your greenhouses. Milton Beychok 22:52, 20 January 2009 (UTC)
