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".
Audits and Consulting:
At Environmental Leverage® Inc., we have a team of experienced individuals who come into your plant with a fresh pair of eyes. The system is checked from influent to effluent. System optimization, equipment efficiency and operational excellence are key components explored. Key Benefits Equipment efficiency Total Cost of Operation reductions Reliability and safety
An onsite audit is conducted to examine system parameters, process controls, and current monitor and control procedures. A physical walk-through is conducted, process flow diagrams are examined, previous design criteria are examined and current standard operating procedures are evaluated along with data logs.
What are Filamentous Bacteria
We have just added "Virtual Audits" to our capabilities. Check out our new Services. We are in the process of developing an ""Online E-University" in order to meet the needs of our global customers that cannot travel to our public classes. Stay tuned for details and updates.
What are Filamentous Bacteria and why are they important to my system?
Filamentous Bacteria are a type of bacteria that can be found in a
wastewater treatment system.
Filamentous Bacteria have Positive aspects:
They are very good BOD removers
Filamentous Bacteria have Negative aspects:
They can interfere with separation and compaction of activated sludge and
cause bulking when predominant.

What are some of the Major Causes of Filamentous Bacteria?
• Grease and Oil
Filamentous Bacteria- How do I know they are there or how can I monitor
Filamentous Identification- Why is it used?
Filamentous Identification should be used as a tool to monitor the health of the biomass when a filament problem is suspected. Filamentous Identification is used to determine the type of filaments present so that a cause can be found and corrections can be made to the system to alleviate future problems. All filamentous bacteria usually have a process control variation associated with the type of filament present that can be implemented to change the environment present and select out for floc forming bacteria instead.
Killing the filaments with chlorine or peroxide will temporarily remove the filaments, but technically it is a band-aid. A process change must be made or the filaments will return with time eventually. Find out what filaments are present, find out the cause associated with them and make a process change for a lasting fix to the problems.

Low D.O. Filaments Control
Type 1701 Adjust the aeration rates or
S. natans F/M( based on aeration solids)
H. hydrossis (Long RAS lines or sludge held too long in the clarifier can sometimes cause the
growth of low D.O. filaments even if the aeration basin has sufficient D.O.
Wastes with Limited Nutrients (N or P) Control
Thiothrix, Nutrient addition BOD ratio
Low F/M ratios Control
Type 0041 Increase RAS,
Type 1851 Increase WAS
Sulfide Compounds or Septic Wastes Control
Thiothrix, Pre aeration or pre-
Beggiatoa chlorination, Check solids holding times, clarifers, digestors
Low FM and septic conditions
Low pH (< 6.5) Control
Fungal filaments Adjust the pH
High Grease and Oil Control
Some filaments have more than one version of the filament species, with
slightly different characteristics for identification.
Well that is great, but I do not have the abilities to identify filaments in my lab myself, now what do I do?
Environmental Leverage Inc. can help you with a Filamentous Identification Wastewater Biomass Lab Analysis.
Filaments can be internally or externally and they can be free of the floc structures or found intertwined in the floc. Most labs think that filaments need to be extending from the floc in order to be a problem. That is not true. Internal filaments can cause more problems than external filaments. Think of internal filaments causing a structure like a sponge. It will retain water easily and be harder to dewater, will be hard to compress and will take up more space, thereby increasing solids handling costs.
Filaments present in the system do not always have to mean a problem. Some filaments are good if they form a strong backbone and add a rigid network to the floc. They help give the floc more structure and settle faster. Filaments are good BOD degraders also. They are only a problem when they become dominant. If filament abundance is in the abundant or excessive range, having a Filamentous Identification performed is recommended.
When Gram and Neisser stains are performed for filamentous Identification, the types of filaments found present will be noted on the Floc Characterization sheet to the right of the filament section and will be noted on the Cover Sheet. A Filament Causes sheet, Filamentous Predominance sheet and corrective actions will be given and included also with the report. A Filamentous Worksheet will be included. Individual sheets on the actual filaments present in the sample will be included with more information on that particular filament.

Ok, you convinced me. How do I go about sending in a sample?
Contact Jennifer or Laurie at Environmental Leverage- 1-630-906-9791 to set up sampling.
What will I need to send in?
Send in 150 mls of MLSS in a small, plastic bottle with at least 1-2 inches of headspace/airspace in the bottle. This will keep sample from becoming septic in transit and remain fresh for your analysis. Seal the bottle carefully. Send overnight by UPS, Fed ex- etc. If possible, pack with blue ice to keep refrigerated.
