Aquafix Announces a New Testing Level for Better Understanding of Your Wastewater: Fatty Acid Analysis

When fats, oil, and grease (FOG) go un-degraded in wastewater, they separate into their base fatty acids. These fatty acids provide the fuel to drive filaments and foaming, can stall out methanogenesis, and cause a host of other problems. When customers come to us suspecting Microthrix parvicella or other foaming filaments, knowing what fatty acids are present can help us direct our treatment recommendations.

Fatty Acid Analysis tests for 25 short-, medium-, and long-chain fatty acids in total. Below we’ve cataloged the main characteristics of some of the most common fatty acids present in wastewater.

We’ve had great success using this testing to determine the most effective treatment between our QwikZyme products, VitaStim line, and Foam Buster. To learn more about Fatty Acid Analysis testing, or to request a test kit, follow the buttons below:

Every year we get a few calls about a fungus in the wastewater treatment process.  It happens when a wastewater plant receives high BOD operates below pH of 7 for an elongated period of time.  If left untreated the fungus will get thicker and make it impossible to settle or dewater.

Aquafix advises applying VitaStim Sludge Reducer, Qwik-Zyme L, and Boost N Lock to the head of the plant.  This combination will out-compete the fungi, it generally takes two to three weeks to rid the system.

Below is a gallery of fungi in a wastewater treatment plant.

anaerobic-digesterThe Digester Doc, a good friend of Aquafix, has been analyzing and improving anaerobic digesters for quite some time.  The Digester Doc performs treatability tests and optimizes the digester’s performance to maximize digestion and biogas production while keeping stability.

Some of Digester Doc services include biogas monitoring, life-cycle analysis, methane potential, and mass balance calculations.  These services may include three to four samples per year with pictures to help the client understand the health, populations, maturity, germination, growth, and methane potential of their digester.

Recently Will Charlton, The Digester Doc, was commissioned to perform a treatability and optimization study for a foaming anaerobic digester. The client is an operator of a 2 MGD municipal wastewater treatment plant experiencing varying degrees of foam for the last three months. The operator feed silicone defoaming agents regularly to combat the foam.  The client didn’t have some of the telltale signs of an upset digester other than the foaming.

Will ran BioMethane Potential tests as well as other treatablity tests. He took substrate from the foaming anaerobic digester, created a bench scale anaerobic digester microcosm, added different amendments and tracked the impact on foam, and methane production. He discovered during testing that Aquafix’s VitaStim Grease performed the best. The client ultimately purchased VitaStim Grease, and has had no foaming since.

Although Will didn’t not find a trace metal deficiency, most common deficiency in digesters, at this particular plant, he can determine if any digester would need Aquafix’s BioGas1, as well as any other bacteria or enzyme solution.

Wastewater odor control products come in all different forms. There is vanilla and cherry masking agents, enzymes, sprayers, carbon filters, and the list can go on and on.  It can be hard to tell what’s the best, but Aquafix has conducted extensive research to understand the source of odors and how to neutralize it.

Noxious odors from wastewater almost always originates from oxygen deprived sewage and undigested waste in treatment process, aka sludge.  Sludge transfer pipes, sludge storage tanks, sludge layers in lagoons, and sewage pipes deficient in oxygen are the main source of horrendous odors that develop into neighboring complaints.

Bioaugmentation for Wastewater Odor Control

In Aquafix’s experience the best odor control is the use of improving bacterial performance and odor neutralizing essential oils.  Targeting the source of the wastewater odors is key, whether is built up sludge in a wastewater lagoon or overflowing sludge storage tank, Aquafix has the advanced biological solutions to degrade it.  Call us for short and long term solutions at lowering your sludge levels and odors.

Odor Encapsulant & Neutralizer

Aquafix has developed specialized odor neutralizing essential oils that encapsulates the odor molecules to break them down. Our DAZZeL wastewater odor control are made specific to your specific odor.

This rendering shows what happens when atomized DAZZeL micron droplets react with odor molecules.

This rendering shows what happens when atomized DAZZeL micron droplets react with odor molecules.

Odors can be uncontrollable due to industry manufacturing or domestic dumping.  When someone dumps on you, you have to act quickly.  A customer of ours gets dumped periodically by a cheese manufacturer, and he recovers by introducing our dairy products and DAZZeL Eco Plus around his ponds.

Industry specific odors are caused purely by the product being manufactured.  Using specialized misting systems our DAZZeL Eco Plus can be diluted 20:1 and provide long-lasting wastewater odor neutralizing results.  Depending on the industry, we also provide DAZZeL Rendering for meat packing plants and DAZZeL Gamma for milk processing plants.

No matter what type of odor you have, preventing sludge production and treating upstream will always lower odors.  For instant and long-lasting results use Aquafix’s biological solutions and DAZZeL to stop the neighboring complaints.

Red worms, blood worms, and midge flies are a normal and occasional nuisance to wastewater operators as they tend to feed off the nutrient-rich mixed liquor, but what does an operator do with tubifex worms?  Tubifex worms, aka sewer worms, are not often seen in wastewater plants, but when they are, they end up clogging filters and eating bacteria and other proteins.
Tubifex Worms

Tubifex Worms

Tubifex worms are very difficult to get rid of, but possible.  Aquafix has recently helped a plant with Tubiflex and red worms clogging their filter system.  This municipal treatment plant in Rhode Island has a 1 mgd RBC, that is followed by three sand filters for up-flow nitrification and down-flow denitrification.  The sand filters are approximately 20’ by 12’ by 8’ of sand.  The Aquafix team came up with a two-part plan to kill both types of worms and clean the filters of excess sludge and proteins.

Part 1: SeClear® and Qwik Zyme P

Aquafix uses a SeClear®, a chelated copper, to kill the tubifex worms, but not harm the good biology.  Qwik Zyme P, an enzyme based product, is used that will break down the food source that the worms have been living on.  The operators let both products soak for 24 hours and then backwashed to the head of the plant.

Part 2: Aquabac Xt

After backwashing the SeClear® and Qwik Zyme P, the operators waited two days and then added Aquabac Xt in each sand filter.  Aquaback Xt is a biological larvacide that contains a species called bacillus thuringiensis that kills red worms.  They let that soaked 24 hours and then backwashed to the head of the plant.

Wastewater lagoons will have high pH when algal growth is maximizing, this is due to the release of oxygen and hydroxide alkalinity when the algae consumes CO2 during photosynthesis.  Every now and then pH can skyrocket when algal activity seems minimal.  This is most likely due to the presence of a planktonic algae, which acts like full grown aquatic weeds at microscopic levels.

Planktonic Algae Increases Lagoon pH

High lagoon pH is most likely due to single-cell planktonic algae.  This type of algae is common in wastewater lagoons as it is driven by high nutrients and sludge buildup.  There are thousands of different species of planktonic algae, but Aquafix typically comes across two types. First is an algae that turns the water a pea soup-like color and this typically spikes the pH to the mid 8’s.

Planktonic Algae Raises Lagoon pH

Planktonic Algae “Pea Soup”

Transparent Planktonic Algae Raises Lagoon pH

Second is a type that turns the water color to only a faint green, but spikes the pH to a high 10 or more.  This can give operatorss headaches as the water will have a high pH, but the visibility, a gallon sample, and effluent will look relatively clear.  Thus giving the impression that an algal presence is non-existent, although that is not the case.  It takes 5 gallons to collect 1 ml of this planktonic algae to identify, but the plant will produce an immense amount of hydroxide alkalinity and skyrocket the lagoon pH.

Best Control Methods

Aquafix has a lot of experience with testing for algae and finding its weaknesses. For this particular type, we use a chelated copper like SeClear® with our adjvant PondZilla Pro, which increases penetration and helps speed up degradation of dead organics.  After we always recommend continuing a sludge reduction program to further clarify the water.

Every restaurant has a grease trap of some sort. It is an unpleasant contraption, but a necessity. Grease traps separate fats, oils and grease under a sink or kitchen and discharges water down into the sewer. The goal of these traps is to stop buildup and clogging that would occur downstream in city-owned pumping and lift stations.  Nearly all grease traps in restaurants are required by law.

Grease traps are simple and work well up to a certain point. Grease and fats will accumulate and clog the system. This causes disastrous outcomes, horrible odors, and major maintenance requirements. Once the grease has built up most restaurateurs will hire someone to come in and physically remove the fats to dispose of it.  This tired method is expensive and not environmentally friendly.  The best alternative is to add specific bacteria that will break down the FOG buildup and keep the waterways clean.  This degradation process is known as bioaugmentation, which highly outweigh the physical alternatives.Bioaugmentation in grease traps

Most of our readers already know bioaugmentation is the process of using selected microorganisms to biologically clean up a specified contaminated area.  Specific nonpathegenic microbes are developed by Aquafix to breakdown difference types of contaminants.  Our GreaseZilla Liquid is a highly potent bacterial product used in grease traps, lift stations, wet wells and other waterways.  With a weekly dose, the bacteria will multiply and degrade the grease carbons and fatty acids.  Using GreaseZilla Liquid is more cost-effective and environmentally-friendly over physically removing it. It also keeps the municipalities happy.

Sphaerotilus natans, more commonly known as S. natans, is a filamentous bacterium that can be found in wastewater treatment plants. It is often responsible for bulking and foaming in activated sludge. Sphaerotilus bacteria grow well under low oxygen concentrations, when there are high levels of hydrogen sulfide either coming into a wastewater treatment plant or being added by chemicals like Ferric sulfate.

Below is a sample from a municipal activated sludge plant that gets periodic loadings from a local cheese producer. It was wet mount stained 1:1 with 1:100 crystal violet viewed under bright field:


 

Bulking Filaments in Wastewater

Sample above viewed at 100X magnification. Floc structure has many long filaments extending into the bulk solution. Some filaments appear to exhibit branching.


 Sphaerotilus Natan Filaments in Wastewater

Sample above viewed at 450X magnification. The filaments in this sample were long, thin, without epiphytic growths and had evidence of branching.


Occurrence of S. Natans

S. Natans In Wastewater - FilamentsSphaerotilus natans hardly ever occur in modern, low-loaded nutrient-removal plants. They regularly cause sludge bulking  in industrial treatment plants containing many easily biodegradable compounds in the influent. Growth in mass of S. natans results in an extremely high SVI.

The following process conditions are favorable to S. natans’ growth in activated sludge:

  • Low levels of Oxygen, Nitrogen, or Phosphorous
  • In the agriculture industry, several low molecular compounds in the influent
  • Sludge load > ca. 0.2 kg BOD/kg MLSS.day
  • Complete mixing in the aeration tank
  • Advantage in high current areas where sheaths allow a means of attachment
  • Optimal growth at 86oF Optimal growth at pH 6.4-8.1

 

Sample above viewed at 1000X magnification. Filament appears to display false branching; meaning two trichomes are stuck together and grow outward without contiguous cytoplasm between the trichomes.


Below is the sample from the activated sludge plant displaying slow settling of solids due to S. natans. From left to right: initially mixed, after 1 hour, and after 2 hours.


Do you think you might have S. natans in your wastewater treatment process? Following are some of S. natans’ most recognizable characteristics which may help you identify the bacteria. Or, send us a sample and we will identify the filament for you. Please give us a call or visit our Lab Services for more information about this service.

  • Often false branching (this is the only filament that exhibits false branching)
  • Immobile
  • Straight to slightly bowed filaments
  • Filament length > 200 μm
  • Filament diameter: 1.0 μm to 2.0 μm
  • Attached growth sometimes present when organism is growing slowly
  • Sheath present (often better visible after Gram staining)
  • Septa clearly visible
  • Rectangular to rod shaped (at the tip of a filament) cells
  • No sulphur storage
  • Gram negative
  • Neisser negative
  • Spherical PHB granules (about 3 per cell) often observed
  • Filaments radiate outward from floc structure into bulk solution

Note: If branching is absent, this species can be confused with Type 0041 (Gram positive, shorter cells), Type 021N (shorter cells, no attached growth, no sheath), or Type 0961 (cells clearly longer and distinctly transparent).

Bulking filament bacteria can be difficult to indentify.  Typical contributors include low D.O., nutrient deficiency, and low F:M.  If you experience problems from any of these filaments call us at 1-888-757-9577 or visit our Lab Services page.  We will work with you to resolve the conditions.

  • Filaments with sulfur deposits – these common filaments use sulfur as their energy source and are usually, but not always, present in septic conditions.  Staining reveals sulfur deposits in the cell structure.
  • Beggiatoa – caused by organic overloading, low D.O.
  • Haliscomenobacter hydrosis – caused by low DO, and possibly phosphate deficiency.
  • Sphaerotilus natans
  • Thiothrix I & II – generally occurs with septic compounds and low DO
  • Type 0041
  • Type 021N
  • Type 0675
  • Type 0914 – caused by low F:M and septic wastes
  • Type 1701 – caused by low DO
  • Type 1851
  • Zoogloea
