Most Wanted Microbes – Legionella

  From the editor: This is the fifth 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. Legionella is a mesophilic, pathogenic organism that can cause Legionnaire’s Disease, a potentially fatal… Read More

Most Wanted Microbes – Nitrifiers (a.k.a. Nitrosomonas)

  From the editor: This is the fourth 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.  Nitrification is a two-part process whereby ammonia is converted to nitrate. The first step… Read More

Day Zero: When the taps run dry

  May 11, 2018: The current estimate (as of February 7) for Day Zero for Cape Town, South Africa, when the municipal water distribution system will be turned off and residents will need to queue for water allotments at 200 distribution points. The current estimate for Day Zero was pushed back from April 16, 2018… Read More

Most Wanted Microbes – Kouleothrix (a.k.a. Roseiflexus)

  From the editor: This is the second 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.  Kouleothrix is a filamentous organism found in wastewater treatment systems. They appear as thread-like… Read More

Most Wanted Microbe – Escherichia coli

  From the editor: This is the inaugural 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.  Escherichia coli or E. coli is a species of bacteria commonly found in the… Read More

Using ATP in a Legionella Water Management Plan

  Between December 2014 and September 2015 there were three clusters of Legionnaires’ disease outbreaks in the Bronx, New York City. Legionnaires’ disease, a severe form of pneumonia, is caused by inhaling aerosolized water containing certain pathogenic strains of Legionella bacteria. Legionella thrive in warm, stagnant water with low disinfection residuals such as hot water… Read More

The cost of high solids in your wastewater treatment plant

  Conventional activated sludge wastewater treatment plants (WWTP) operate with solids (mixed liquor suspended solids ­– MLSS) concentrations ranging from approximately 1500 to 5000 mg/L. In membrane bioreactors (MBRs), typical MLSS concentrations are even higher (10,000 to 12,000 mg/L). A higher concentration can be advantageous as they allow for smaller aeration tanks while performing the… Read More

Enhanced Biological Phosphorus Removal – Who’s doing the work?

  Enhanced biological phosphorus removal (EBPR) was first documented in the early 1970’s. Traditionally it has been understood that EBPR requires a first stage anaerobic zone that is free of nitrate and nitrite. In the anaerobic zone, phosphorus accumulating organisms (PAO) utilize energy from stored polyphosphate to assimilate volatile fatty acids (VFAs) and produce polyhydroxybutyrate… Read More

How often should I measure ATP in my wastewater treatment plant?

  LuminUltra’s 2nd Generation ATP has many potential uses within a wastewater treatment plant (WWTP), including: diagnosing acute and chronic toxicity, optimizing solids concentrations in the aeration tank, optimizing dissolved oxygen setpoints and identifying sludge bulking events. How often you should measure ATP depends on the quantity of data you’ve collected, the operational performance of… Read More
