Welcome!
Hello, and welcome to Wikipedia! Thank you for your contributions; however, please remember the essential rule of respecting copyrights. Edits to Wikipedia, such as your edit to the page Activated sludge, may not contain material from copyrighted sources unless used with permission. It is almost never okay to copy extensive text out of a book or website and paste it into a Wikipedia article with little or no alteration, though you can clearly and briefly quote copyrighted text in the right circumstances. Content that does not comply with this legal rule must be removed. For more information on this, see:
 * Copying text from other sources
 * Policy on copyright

 * Policy and guideline on non-free content

If you still have questions, there is the Teahouse, or you can and someone will be along to answer it shortly. As you get started, you may find the pages below to be helpful.

Hello, I'm MrOllie. I noticed that you added or changed content in an article, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Thank you. MrOllie (talk) 20:52, 19 January 2023 (UTC)
