10. Understanding Pump Cavitation

In the No. 10 spot is this technical article that explains pump cavitation, the factors involved in increased cavitation and some recommendations for decreasing the problem. Definitely an article plant operators should bookmark. 

9. Wastewater Plant Lays Groundwork for New Sci-Fi Novel

In a more lighthearted blog, Digital Editor Briana Jones wrote about a sci-fi horror book set in a wastewater treatment plant. TPO readers appreciated the cultural nod to the industry, and perhaps related to author Dodge Winston’s comment: “When you work a graveyard shift, a wastewater plant can be eerie and creepy.” 

8. Nutrient Removal: Many Options Available for Wastewater Treatment 

High priority on quality effluent and sustainability made this article a top pick for TPO readers. This handy guide explains several processes for nutrient removal, including membrane bioreactor systems, sequencing batch reactors and more. 

7. "Flushable" Products: Silent Killer of the Utility’s Budget and Reputation 

Ah, the bane of a treatment plant operator’s existence: “flushable” products. We know you love to hate them. This article, which summarized the third edition of the Guideline Document for Assessing Flushability of Nonwoven Disposable Products, drew a lot of attention from treatment plant operators. Where does the discussion go from here? 

6. Greening the Plant: Better Recipe

Now here’s a plant worth reading about. And it seems our readers agreed.

The Haines City (Fla.) Wastewater Treatment Plant found a way to recycle its biosolids more easily, produce a product for reuse on agricultural fields, and at the same time meet new regulations, cut operating costs and reduce odors.

Find out how choosing a Neutralizer process from BCR Environmental kept the plant on track. 

5. Brewery’s Anaerobic Digester System Reduces Loading to Municipal Wastewater Treatment Plant 

At the halfway point, in the No. 5 spot, is a story of a forward-thinking brewery in upstate New York. Matt Brewing Company, which is known for its distinctive-tasting Saranac craft beers, caught the eye of TPO readers not for its beer, but for its wastewater treatment system. The progressive system cleans up to 80 percent of the brewery’s wastewater, taking a tremendous load off the municipal sewer system. 

4. Body Parts Found at Two Facilities Could Be Linked

A bit more macabre than other top articles, this blog post by Digital Editor Briana Jones drew quite a bit of attention from the TPO readership. But then again, how often do body parts from the same person show up at different treatment plants? That’s what happened at the interconnected plants in Whittier, Calif., and Carson, Calif. It’s enough to send shivers down a plant operator’s spine. 

3. Modified Settleability Test for Activated Sludge Treatment 

Coming in next is this primer on settleability tests, which discussed the basic test and offered some insight on a modification known as the diluted settleability test.

This reference article is yet another comprehensive primer worth bookmarking. You’ll come back to it time and again. 

2. EPDM Failure Causes Anaerobic Digester Explosion

Ranking No. 2 is a story about an unlikely event: the explosion of an anaerobic digester. But odd things happen, which is exactly what Tim Bielenberg at Oak Lea Farm in Aumsville, Ore., discovered when the farm’s Revolution Energy Solutions digester exploded. Learn exactly what happened and see how RES used the incident as a learning experience. 

1. Process Control Using Sludge Volume Index (SVI)

And finally, in the No. 1 position for 2013 — the most popular story of the year for TPO readers — was this follow-up article on sludge volume index that answered some reader questions, clarified formula results and dug deeper into the topic of SVI.

You better bookmark this one! This comprehensive primer is an article worth referencing over and over.
