The Impact of Quaternary Ammonium Compounds (QACs) on Wastewater Biomass and the Role of Biochemistry in Managing QAC Degradation and Toxicity

by Erik Rumbaugh | Oct 6, 2025 | Uncategorized

Quaternary Ammonium Compounds (QACs) are commonly found in disinfectants, detergents, and personal care products. Their extensive use has led to increased concentrations in wastewater. To better understand how this impacts biological wastewater treatment, let’s...

Bridging the Gap: How Polyvalent Cations Strengthen Wastewater Treatment

by Erik Rumbaugh | Sep 26, 2025 | Biofilms, Biomass Optimization

In wastewater treatment, invisible forces shape the performance of entire systems. One of the most powerful—and often overlooked—players in this microbial drama is the polyvalent cation. These positively charged ions, like calcium (Ca²⁺), magnesium (Mg²⁺), and iron...

Why Wastewater Turns Septic—and What It Means for Treatment Plants

by Erik Rumbaugh | Sep 16, 2025 | Uncategorized

Wastewater treatment is a complex process that relies on a delicate balance of physical, chemical, and biological factors. At the heart of most conventional wastewater treatment plants are microorganisms that break down organic waste. However, when this balance is...

💧 Why Influent TKN Matters More Than Just Ammonia in Wastewater Treatment

by Erik Rumbaugh | Sep 3, 2025 | Uncategorized

When it comes to nitrogen monitoring in wastewater, ammonia often steals the spotlight. But if you’re only tracking ammonia, you’re missing a critical piece of the puzzle: Total Kjeldahl Nitrogen (TKN). TKN includes both ammonia and organic nitrogen—and...

The Hidden Universe: Understanding Microbial Dark Matter

by Erik Rumbaugh | Aug 29, 2025 | Uncategorized

Ever wondered what we’re missing in the microbial world? Just like astronomical dark matter makes up most of our universe but remains largely mysterious, microbial dark matter represents the hidden majority of life on Earth – over 99% of microbial species...
