BIRMINGHAM, Ala. — Every month we receive several questions from our readers to be answered by our technical editor.

The best questions are selected and used in our print edition of the magazine and posted online.

If you have a question you would like to have answered by Professor POU/POE please submit it to Editorial Director Rich DiPaolo at rdipaolo@watertechonline.com.

Thanks for your continued support of Water Technology and www.WaterTechOnline.com
