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 analysesof your own MLSS for more information
This filament is very common in grease and oil environments. 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 (10-50 µm). Irregularly bent filaments with no branching. The filaments sometimes coil giving it the appearance of almost being branched. Cells are oval-shaped rods (0.8-1.2 x 1.5 µm) and lack a rigid trichome. There are indentations at the septa. Filaments are found extending from the floc surface and free in the bulk solution. The filament staining is Gram negative, but can be Gram positive and Neisser negative. Neisser positive granules may occur. Usually easy to identify due to its appearance as a ‘chain of sausage-like cells���. No sulfur granules. No attached growth. No sheath. This filament occasionally is observed as a cause of foaming. Typically when there is a high F/M ratio or at MCRT’s of less than 2 days. The foam is usually white-grey and is easily collapsed.
Bacillus is similar although is stains Gram positive.
This filament is usually found in environments where there is a low D.O. or high grease and oils with easy to degrade compounds. It can also be found after RAS Chlorination. Foaming can be found when high F/M conditions with low MCRT conditions exist.
Control: F/M can be changed by decreased sludge wasting, changing from complete mix to plug flow. Grease control upstream with DAF or bioaugmentation can also help.
Rank: 1863 is not found on most charts being ranked at less than 19 or more.
