Welcome to Wikipedia. Although everyone is welcome to contribute to Wikipedia, at least one of your recent edits, such as the one you made to Waste management, appears to have been inappropriate, and has been reverted. Please feel free to use the sandbox for any test edits you would like to make, and read the welcome page to learn more about contributing constructively to this encyclopedia. Thank you. - The material you copied is already at Landfill, which is linked from that section. In any case, such a copy (without attribution) is a breach of copyright, see WP:Copying within Wikipedia. --David Biddulph (talk) 08:41, 6 April 2017 (UTC)

Hello, I'm Oshwah. Wikipedia is written by people who have a wide diversity of opinions, but we try hard to make sure articles have a neutral point of view. Your recent edit to Ethanol precipitation seemed less than neutral to me, so I removed it for now. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks.  ~Oshwah~  (talk) (contribs)   07:11, 19 April 2017 (UTC)

Welcoming advice
Welcome to Wikipedia. Here are suggested readings for new editors: WP:SECONDARY and WP:COI. The gist of these guidelines are: If you have questions, many editors can offer advice and help. Happy editing!--Smokefoot (talk) 13:25, 20 April 2017 (UTC)
 * Wikipedia prefers citations to reviews and books, not primary journal references (tens of thousands appear annually). Citing secondary sources is the encyclopedic style.
 * Do not cite yourself or your colleagues. It's called conflict of interest.  Many new editors cite themselves mainly.  That behavior is unacceptable.

Hello, I'm Velella. I wanted to let you know that one or more external links you added to Nanofiltration have been removed because they seemed to be inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page, or take a look at our guidelines about links. Thank you.

Please stop your disruptive editing. If you continue to add soapboxing, promotional or advertising material to Wikipedia, as you did at Nanofiltration, you may be blocked from editing.  Velella  Velella Talk 12:18, 24 April 2017 (UTC)

You may be blocked from editing without further warning the next time you use Wikipedia for soapboxing, promotion or advertising, as you did at Micro-encapsulation.  Velella  Velella Talk 12:19, 24 April 2017 (UTC)
