NESC Offers Filter Backwashing PowerPoint Presentation

(Editor’s Note:  This article appeared in the April 11 edition of NDWC News)

Are you a technical assistance provider or training professional who provides instruction about filter backwashing? Maybe you’re a new water operator who would like to learn more about this important task? Whatever the case, the National Environmental Services Center (NESC) has developed a free PowerPoint presentation that provides an overview of filter backwashing.

The PowerPoint, available at (scroll down to item 34), includes the different steps undertaken when cleaning a sand filter and features a six-minute video of the process. The PowerPoint complements an existing Tech Brief about the topic, also available at the link above.

“Filter backwashing is one of the most important steps a system performs,” says Zane Satterfield, NESC engineering scientist. “Without a properly functioning filter, a system won’t be able to provide quality drinking water to the community and may fall out of compliance with health regulations.”

If you have questions about filter backwashing or other drinking water or wastewater topics, call NESC’s toll-free help line at (800) 624-8301 and select option “3.” A complete list of Tech Briefs, four-page fact sheets providing concise, technical information about a drinking water treatment technology or issue relevant to small systems, may be found
