Filamentous Identification Lab Service. One reason to identify filaments is to determine the filaments characteristics and then determine the type present. If the type is found out, a root cause can usually be associated with a particular filament. If the cause is known, then a correction can be made to alleviate problems. Chlorination is only a quick fix. Without process changes, filaments will grow back after chlorination.

Training is an integral part of any job. Not everyone is at the same level of training. Many people want beginning concepts and basics. Some need technical information or troubleshooting. Some want equipment, technology or process information.
We have developed a full set of Basic training, Advanced training, Filamentous Identification the Easy Way as well as custom training CD's Manuals. We also provide hands-on training classes and soon will have an Online "E-University".
We hope you like the new look of our Filamentous Bacteria Identification Pages
If you would like more information on filaments, you might want to consider purchasing our Filamentous Identification the Easy Way Training materials.
We also have our lab that can perform a Filamentous identification lab analysesof your own MLSS for more information
This filament is extremely easy to find in Neisser. You may not even notice it in Gram. Don't get overly technical. When trying to determine species, stick to the basics, and focus on the causes and controls of the filaments present. The main point of any filamentous identification is not to get a PhD, but to fix your plant!
Relatively small, non-motile filaments (10-60 µm). Straight, irregularly curved or bent filaments with no branching. Cells are rectangular (0.8 x 1.5 µm) and no constrictions at the septa. Filaments are found mostly within the floc structure causing diffuse floc with poor settling. The filament staining is Gram negative and Neisser positive. Usually overlooked until stained and then it’s easy to identify due to the fact that the entire trichome stains Neisser positive. Appears wider when dried on a slide and stained. Intracellular granules not observed. No sulfur granules. Usually no attached growth. No Sheath.
N limicola is similar only in causes and both are Neisser positive usually appears along side of Type 0092 when high septicity is present.
This filament is often found in environments with high septicity. This filament can be found in environments where there low F/M (0.02-0.2) and with a long MCRT (10-40 days).
Check solids holding times for septicity or dead spots, center wells with scum or sludge build up. F/M can be changed by increased sludge wasting or changing from complete mix to plug flow. Also check for septic supernatant from dewatering processes.
Type 0092 ranks 8th in number of predominance.
