Old Sludge – what is it and why is it a problem for wastewater treatment

by Erik Rumbaugh | Feb 12, 2025 | Biomass Optimization, Filamentous Bulking, Sludge

In wastewater treatment plants, biomass solids is a byproduct of the treatment process. It consists of a mixture of organic and inorganic materials, microorganisms, and bound water. Over time, sludge can age and transform into what is known as “old...

Impact of Surfactants on Wastewater Treatment Plants

by Erik Rumbaugh | Feb 3, 2025 | Uncategorized, Wastewater Troubleshooting, Whitepaper

Surfactants, or surface-active agents, are among the most common chemcials used in both households and industrial facilities. Found in everything from personal care products to industrial cleaners, these chemical compounds reduce surface tension between two...

Unleashing the Power of Postbiotics in Wastewater Treatment

by Erik Rumbaugh | Jan 23, 2025 | Biomass Optimization, Postbiotics

You have probably read about probiotics (bioaugmentation) and prebiotics being used in wastewater treatment, postbiotics are another less talked about potential tool available for optimizing your biomass performance.  Postbiotics application in wastewater treatment is...
