The two sections of this article about "Dissolved gas flotation" have been moved to a stand-alone new article entitled Dissolved gas flotation. The subject of gas flotation deserves a stand-alone article just as is the case with Froth flotation and Induced gas flotation ... both of which are also stand-alone articles.
"The feed water to the DAF float tank is often (but not always) dosed with a coagulant (such as ferric chloride or aluminum sulfate) to flocculate the suspended matter." -Coagulants coagulate, flocculants create flocs. I think this is an error. It's possible that they are dosing with flocculant _and_ coagulant (the two are often used together), but we shouldn't be stating that a coagulant does the flocculating. Does anyone know which is used? (or are they both used in these applications)?Tara Zieminek (talk) 17:16, 2 May 2015 (UTC)
