thread_title:  Commercial links 

message: I moved the "Water treatment" section from the article to this talk page. It is apparently off-topic. There is a broad article on Water treatment which discusses both wastewater treatment and the commonly-described "Water treatment" processes for preparing water for manufacturing or commercial uses. The paragraph below appears to refer to the latter process (albeit unreferenced) and is therefore off-topic in an industrial wastewater article.
:===Water treatment===
:Many industries have a need to treat water to obtain very high quality water for demanding purposes such as environmental discharge compliance. Water treatment produces organic and mineral sludges from filtration and sedimentation. Ion exchange using natural or synthetic resins removes calcium, magnesium and carbonate ions from water, typically replacing them with sodium, chloride, hydroxyl and/or other ions. Regeneration of ion exchange columns with strong acids and alkalis produces a wastewater rich in hardness ions which are readily precipitated out, especially when in admixture with other wastewater constituents.

replies: text: I agree with you, Moreau1. This sentence makes no sense to me: "Many industries have a need to treat water to obtain very high quality water for demanding purposes such as environmental discharge compliance." What is meant here?? EMsmile (talk) 20:00, 1 December 2017 (UTC)
replies: text:  I have changed the wording now, making it easier to understand. It's still not very easy to understand for lay persons though. EMsmile (talk) 02:29, 22 April 2021 (UTC)
thread_title:  "Water treatment" section 

message: I'm proposing some further work for this article (have it also on my to-do list but might be a while before I get to it):
# Apart from just sources and treatment methods we also should have some sections on management aspects, costs, regulations, enforcement (like trade waste licences), interactions between industrial wastewater and municipal wastewater, e.g. when industries pre-treat and then discharge to the sewer.
# If such information exist: try to look at the global perspective, i.e. which countries are treating all their industrial wastewater; which countries discharge untreated wastewater to rivers (this is a problem in e.g. India and Bangladesh). I don't have that information on my fingertips but it's likely available. 
# Could also mention one of the indicators of SDG 6 which is: 6.3.1 Proportion of domestic and industrial wastewater flows safely treated. I found one map for this but it doesn't show industrial wastewater separately, only domestic wastewater (which usually does contain wastewater from small industries). See thumb nail image on the right.

replies: text: I've now added some excerpts and some links to related articles where people can find more information. I've also added a mention of SDG 6. Point 1 and 2 from the list above would still have to be done. EMsmile (talk) 10:33, 19 May 2022 (UTC)
thread_title:  Proposed further work 

message: "industrial wastewater treatment and disposal may be less expensive than correctly apportioned costs for larger volumes of industrial wastewater not requiring the conventional sewage treatment sequence of a small municipal sewage treatment plant." I have hard understanding them, and I have no way to refer to the cited book source. Can anybody help? Thanks. ThomasYehYeh (talk) 03:08, 2 April 2023 (UTC)
replies: text: Hi User:ThomasYehYeh, you are right, this sentence was way too complicated. I've tried to improve on this now. I also don't have access to that particular textbook but this is pretty standard knowledge (and could be found in other sources too). EMsmile (talk) 08:45, 20 April 2023 (UTC)
