Understanding Net Zero Energy in Wastewater Treatment

Water resource recovery facilities (WRRFs) are among the most common pieces of municipal infrastructure. It’s accepted practice for communities of all sizes to treat wastewater in some way before returning it to the environment. As the worldwide focus on issues like water quality and waterborne diseases has increased, so has the attention being paid to… Read More

Smart dogs sniff out leaky pipes

  Using a highly unique solution to a common and sometimes vexing problem, a cocker spaniel and a springer spaniel in Britain are finding leaks in drinking water pipes by using their sensitive noses to sniff out the chlorine in the water. Snipe, a two-year-old cocker spaniel, received months of training from his handlers, who… Read More

Top 3 Things I Learned at WEFTEC 2018

  Whether I’m talking to attendees or customers in our booth at WEFTEC, or attending presentations, I always walk away with valuable information. That is the key, as you’ll see in my #1 take-away from WEFTEC.   1. Data ≠ Information I initially heard this statement during Dr. Mark van Loosdrecht’s presentation on wastewater microbial… Read More

Sequencing Your Bioreactor – Who’s Doing the Work?

  Metagenomics through the incorporation of next generation sequencing (NGS) is changing the way wastewater treatment plants are monitored and understood. NGS can be used in aerobic and anaerobic systems to monitor for problematic organisms, such as filamentous and foaming bacteria, and beneficial organisms, such as ammonia-oxidizing bacteria and methanogens. NGS is also allowing old… Read More

Most Wanted Microbes – Methanogens

  From the editor: This is the thirteenth post in an ongoing series profiling microorganisms of particular significance in water and wastewater systems. In this series we will cover microorganisms of many types including some that are beneficial, inhibitory and pathogenic.  Methanogens are a group of microbes that produce methane gas through the breakdown of… Read More

Amazing Water Resources

  If you find it easiest to understand a new concept through some type of visualization, you’re not alone. If you happen to be a ‘visual’ person and have an interest in water, there are a ton of great resources available online that can bring out the map-geek and marine biologist in anyone. Here at… Read More

Most Wanted Microbes – Candidatus Accumulibacter

From the editor: This is the eleventh post in an ongoing series profiling microorganisms of particular significance in water and wastewater systems. In this series we will cover microorganisms of many types including some that are beneficial, inhibitory and pathogenic. Candidatus Accumulibacter is a phosphorus accumulating organism (PAOs), meaning it can store copious quantities of phosphorus under specific conditions in a process referred to as enhanced biological phosphorus removal. Systems that select for Candidatus… Read More

Most Wanted Microbes – Coliforms

From the editor: This is the ninth post in an ongoing series profiling microorganisms of particular significance in water and wastewater systems. In this series we will cover microorganisms of many types including some that are beneficial, inhibitory and pathogenic. Coliforms are a group of gram-negative, rod-shaped bacteria that generally belong within the family of… Read More
