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 Page
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
This filament looks like tiny pins and needles. 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 short, non-motile filaments (20-100 µm). Straight or bent filaments with no branching. Cell shape is concealed (0.5 µm). Filaments are found within the floc structure causing elevated SVI. Free in the bulk solution in severe cases. The filament staining is Gram negative and Neisser negative. Usually easy to identify due to its needle like appearance in a pin cushion. Intracellular granules not observed. No sulfur granules. Bundles of trichomes and attached growth are common. Sheath is difficult to detect and no cell septa.
Type 1851 is similar although longer and has attached growth.
This filament is usually found in environments where there low F/M, nutrient deficiency and low D.O. Usually overlooked due to its’ size at low magnification. It can appear as pins and needles in a pin cushion. This filament causes TSS problems as opposed to others that cause bulking and bridging.
F/M can be changed by increased sludge wasting, changing from complete mix to plug flow. Chlorination should be definitely used if in the rapid growth phase. Increase D.O. and add nutrients if this is the situation. Nutrient deficient wastes can be checked by effluent values of residual NH3 and o-PO4 and should be supplemented if necessary.
H. hydrossis ranks 9th in number of predominance
