Microthrix Parvicella
Microthrix Parvicella es un filamento Gram positivo y Neisser negativo que muchas veces se forma de hilos largos y delgados, agrupados en enredos que parecen a pilas de espaguetis, y sin evidencia de ramificación o septos visibles en las células (1). Cuando se...Sphaerotilus natans
Sphaerotilus natans en el fango activado de plantas Sphaerotilus natans, comúnmente llamado S. natans, es una bacteria filamentosa que muchas veces se puede encontrar en las plantas de tratamiento de aguas servidas. A menudo es la causa principal de “bulking” y...
Sphaerotilus natans (S. natans) Treatment
Sphaerotilus natans (S. natans) is a large gram negative filament that causes lots of bulking in wastewater if proper conditions exist. It is usually easy to identify because of its false branching, and large sausage-shaped cells. False branching is when two of the...
Winter Foaming in Wastewater due to M. Parvicella
en Español In the winter when wastewater temperatures are between 50-65°F (10-18°C), fat, oil, and grease are broken down incompletely to form long chain fatty acids such as Oleic acid. Oleic acid is taken up by the filamentous bacterium Microthrix Parvicella which...Wastewater Surfactants 101
Surfactants are some of the most difficult things to breakdown in wastewater, especially true in the winter months, and are possibly one of the most recurring issues for wastewater plants. Surfactants, or surface activating agents (a fancy name for soap), are...What Are Foaming Filaments?
A: Three hard-to-treat filaments are the main cause of excessive foaming in wastewater plants (WWTPs). Unfortunately, correctly identifying the filament bacteria in your system can be difficult.
What Are Branching Filaments?
Fungi, Nocardia, and Sphaerotilus Natans are three filamentous bacteria found in wastewater treatment systems (WWTPs). In small amounts, they are quite beneficial for the system as they add stability to the floc structure and keep it from breaking up or shearing. In...
