message: This article was created in rather high quality by a single user in a single edit.  This makes me suspect it may have been a wholesale ripoff from a copyrighted source.  It is also possible that this was taken from some public-domain source.  This article either needs to show its source or be deleted as a copyright violation. --Dgies 07:04, 10 December 2006 (UTC)

message: I'm proposing to merge Ejector venturi scrubber with Venturi scrubber. As far as I can tell, both articles talk about the same subject. Since all the action seems to be on this article I think Ejector venturi scrubber should be injected here (pun intended). ʍαμ$ʏ5043 19:01, 6 March 2007 (UTC)
replies: text: Your proposition is not founded. Ejector venturis and venturi scrubbers may be similar but if you really think the articles talk about the same subject, you should've noticed that ejector venturis DO NOT have a fan. Plus that ejector venturis are part of the category liquid-phase contacting scrubbers, which means that they use the liquid energy (through a nozzle) to remove the pollutants, while venturi scrubbers, although they have nozzles, these are used to wet the surfaces only. Venturi scrubbers use the exhaust gas stream to provide the energy for gas-liquid contact. So they're quite different. The Vindictive 19:29, 6 April 2007 (UTC)
replies: text: As a chemical engineer who is quite familar with this subject, I agree with The Vindictive that the two articles should not be merged. - mbeychok 19:18, 7 April 2007 (UTC)
replies: text: I am a chemical engineer too, but many other readers may not be. Reading both articles I found that a lot of information is duplicated in the articles right down to the layout and the references (the deja-vu feeling was tremendous ;-) ). Also the basic shape of both devices is the same. To the none-initiated both articles, and therefore both devices, show a high degree of similarity. As a result it is easy to confuse them. Especially the ejector venturi scrubber article is relatively short when compared to the venturi scrubber article. If you remove the duplicated information from the ejector venturi scrubber article there is not much of an article left. Therefore, my proposal is still to merge both articles. I might be a challenge. However, as far as the duplicate information is concerned there should be no discussion. Then, adding a chapter discussing different uses and (most importantly, because that information is not supplied in either article right now) clarifying how and why they differ should be helpful and complete the merger. —The preceding unsigned comment was added by Mausy5043 (talk • contribs) 16:42, 14 April 2007 (UTC)

text: Chemical engineering has little in common with air pollution control (as Mbeychok said). I am an air pollution control specialist and having also created the articles, I am sure there can be no such merger. No offense intended, I am waiting for more opinions from experts in air pollution control systems and scrubbers in special. The Vindictive 13:32, 15 April 2007 (UTC)
replies: text: No offense intended here aswell. I appreciate you being the original author of both articles and that you may have emotional attachments to them. But, I hope you can take a step back and look at both articles. Not to see how they differ, but please try to objectively judge their similarity. Then, as I mentioned above I hope you see that merging them is possible. I'm willing to share my ideas if you're interested. ʍαμ$ʏ5043 10:54, 16 April 2007 (UTC)
replies: text: I don't have any emotional attachments to these articles. It's about the substance. We can discuss the matter further, I have my e-mail activated on my user page. The Vindictive 12:34, 16 April 2007 (UTC)

text: I recently proposed this merger from the Ejector Venturi page without seeing that there had been discussion of the subject here.  I am a nonspecialist and not intimately familiar with Wikipedia article merge procedure.  I see that there are differences in the principles employed; however, both technologies create small liquid droplets onto which particles are adsorbed as they pass through a Venturi constriction, as a method for particle removal.  It does seem to me as though one is a subset of the other.

replies: text: Ah, I had not checked the discussion here at that time. There are some good points raised about the differences, but think that is still outweighed by the similarities in purpose and the simplicity of integrating them as two sections of the same article. As I see it the primary difference is just in the source of the mixing energy (water spray or gas flow), and consequently the ability of one to act as a pump for the process gas. I think the other differences are relatively minor compared to the similarities. MasterTriangle12 (talk) 06:21, 5 July 2021 (UTC)
