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.
Wastewater Biomass Analyses and Cooling Tower Analyses also available
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 analyses of your own MLSS for more information
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 large, motile filaments (100-500 µm). Straight filaments with no branching. Cells are rectangular (1-3 x 4-8 µm). Filaments are found free in the bulk solution and are motile with a gliding and flexing movement. The filament staining is Gram negative but may stain Gram positive if sulfur is present and Neisser negative with Neisser positive granules observed frequently. Usually easy to identify due to it's gliding motion. Contains substantial refractile spherical sulfur granules and the cell septa is not visible when sulfur is present. No Sheath. No attached growth.
This is the only actively motile filamentous bacteria strain. There are gliding cyanobacteria and algae, but they are green
This filament is usually found in environments where there are septic wastes and sulfides. It is commonly observed in activated sludge, but rarely causes bulking. If it does, it is usually inter-floc bridging. Beggiatoa is found in RBC units and trickling filters and can cause clogging of filters and growth overloading on RBC units that can lead to shaft failures.
Septic influent wastes can be altered by pre-aeration or pre-chlorination. Check solids holding times in clarifiers and primaries. Also check for septic supernatant from dewatering processes.
N. limicola ranks 12th in number of predominance in industry. Typically not found in kraft mills. Common in municipalities.
