Lab Services:
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 Materials:
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".

Type 0961
Latest News!
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
Type 0961 This filament may look different. It may be shorter in slow growth, and very elongated in a high growth phase similar to type 0411. 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!
Identification Relatively short, non-motile filaments (20-150 µm). Straight filaments with no branching. Cells are rectangular and irregular (0.8 - 1.4 x 1.5-4 µm) with a rigid trichome. The septa is clear with no indentations. Filaments are found extending from the floc surface. The filament can sometimes be seen in bundles when abundant. The filament staining is Gram negative and Neisser negative. No attached growth. Usually easy to identify due to the its transparent “empty” appearance lacking any internal structures . No sulfur granules. True sheath is not present but sometimes a slime coating is present which appears as one.
Similar Organisms: Type 0411 is similar although shorter cells and more round ended cells. Type 0211 is similar but a smaller version. All three have the same cause and controls.
Environment This filament is usually found in environments where there is high septicity. It very rarely causes bulking and never bridging since it is too small. This filament is usually found in environments where there are septic wastes, or wastes with sulfides or organic wastes, it can also be associated with the generation of organic acids.
Control: If the S test is positive, the cause is septic wastes or presence of sulfides and can be remedied by pre-aeration or pre-chlorination. RAS chlorination should be used. Check clarifier holding times or primary clarifier or EQ tanks for septic conditions. Also check for septic supernatant from dewatering processes.
Rank: Type 0961 is ranked 14th in predominance. Very rarely a dominant filament.
