Does the wastewater treatment plant smell bad?
While wastewater treatment plants do smell, it’s important to reduce those smells for several reasons. First, you don’t want people who live nearby to constantly complain to the town or city about the odors. Second, those odors are linked to harmful gases being released during the treatment process. Odor management helps protect the environment.

What is organisms in wastewater?
Common Metazoa in Wastewater These organisms feed on microbial floc and protozoa. An abundance of metazoa indicates an older sludge. Common wastewater metazoa include rotifers, nematodes, bristle worms and tardigrades.
What are the four stages of wastewater treatment?
Four common ways to treat wastewater include physical water treatment, biological water treatment, chemical treatment, and sludge treatment. Let us learn about these processes in detail. In this stage, physical methods are used for cleaning the wastewater.
What is called sludge?
The residue that accumulates in sewage treatment plants is called sludge (or biosolids). Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a by-product of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge.
What is the best wastewater treatment system?
To give a short answer, the best system on the market is the ClearFox Nature. This is a totally non-electric plant, and it is the only non-electric treatment plant in the world that does not require replacement parts or media. So, the best non-electric sewage treatment plant is without a doubt the ClearFox Nature.
Which bacteria is used in aeration tank?
Aerobic bacteria are used in most new treatment plants in an aerated environment. This means that there is dissolved oxygen available for the respiration of the bacteria. They use the free oxygen in the water to degrade the pollutants in the incoming wastewater into energy they can use for growth and reproduction.

What are the creepy crawly organisms that are seen under the microscope?
The protozoa and metazoa are the creepy crawly looking organisms seen under the microscope that also are very important indicators to the wastewater operator about how his/her plant is performing. The chart below illustrates the relative predominance of protozoa and metazoa to produce good settling of the activated sludge.
What are the three types of bacteria?
There are three types of bacteria: free swimming bacteria, flocculated bacteria and filamentous bacteria. As the bacteria in the activated sludge keep growing, they produce flocculating agents to stick together.
What is activated sludge made of?
Activated sludge typically will be made up of 95% bacteria, 4% protozoa and 1% metazoa. Bacteria removes nutrients in the wastewater while protozoa eats the bacteria and metazoa consumes bacteria and the protozoa. There are three types of bacteria: free swimming bacteria, flocculated bacteria and filamentous bacteria.
What is wastewater treatment plant?
A wastewater treatment plant is a biological "bug” factory. You need to grow bacteria to successfully meet final effluent permits. There are no replacements for the biological activity.
What is the microscope used for in wastewater treatment?
Using the microscope to troubleshoot your wastewater treatment plant is the most important thing you can do. The microscope is the most powerful tool to tell you what is going on with your MLSS. What is your sludge age, do you have filaments or nice golden floc? What process changes should you make for the optimum results at your wastewater treatment plant? This microscopic wastewater training module will walk you through steps necessary to use the Microscope.
What is the biological stage of wastewater treatment?
the biological stage is the growth of a biomass to degrade organics and remove pollution. The bacteria are really what you want to look at. The higher life forms are nice, they indicate the age and health of the biomass, but the bacteria are the actual workhorses of the wastewater treatment system.#N#In this section, we will look at the basics of the typical bacteria found in your wastewater treatment plant.
What is wastewater training?
These wastewater training courses are designed to teach you more about Wastewater Microbiology, How to use the Microscope, and How to correlate the information into real time operation changes at your facility.
What bacteria are used in wastewater treatment plants?
Almost all commercially available bacteria blends only contain a mix of Bacillus. Bacillus is an excellent treatment of bacteria in wastewater but is best suited for treating fats, oils, greases, and proteins. That is why they are primarily used in wastewater treatment plants. The primary constituents of brewery, winery, and food processor waste are sugars and carbohydrates in very high concentrations. This makes their waste dramatically different than sewage treatment plants. The best bacteria for breaking down sugars and carbs are Pseudomonas. Pseudomonas will act very quickly on them and will reduce BOD levels far more rapidly. The blend ClearBlu offers contains multiple strains of Bacillus as well as two proven strains of Pseudomonas: Pseudomonas fluorescens and Pseudomonas putida. Both have additional important benefits. Fluorescens will grow in water temperatures as low as 5 degrees C which makes it far more beneficial than Bacillus in treatment ponds during winter months. Putida has the added benefit of converting nitrates to nitrites. For all new and renewed discharge permits many state agencies are now requiring limits for nitrates as they have become a significant contributor to groundwater contamination. Putida, in addition to its work on carbohydrates, will aerobically convert nitrates to nitrites which can be readily consumed by plants.
What are the constituents of brewery waste?
The primary constituents of brewery, winery, and food processor waste are sugars and carbohydrates in very high concentrations. This makes their waste dramatically different than sewage treatment plants. The best bacteria for breaking down sugars and carbs are Pseudomonas.
What is Bacillus Subtilis (Microbes)?
Bacillus subtilis, also known as grass bacillus or hay bacillus, is a rod-shaped bacterium. It is found in soil and the gastrointestional tract of ruminants and humans. As with other members of the genus Bacillus, it can form and endospore to survive extreme environmental conditions of temperature and desiccation. It is one of the bacterial champions in secreted enzyme production and use on an industrial scale by biotechnology companies. Magnification is 10,000x at 15cm image size. ClearBlu offers the highest strength industrial grade bacteria available in two blends. Bred and blended in sterile lab conditions, these bacteria will dramatically improve the digestion process in your water treatment plant and other equipment such as biodigesters.
What is clearblu dry microbes?
ClearBlu dry microbes are available in blends with all bacillus strains, or with bacillus and two strains of pseudomonas and come freeze-dried on wheat bran or a salt/sugar carrier. Bacillus only blends are effective for municipal or industrial waste streams with minimal oil and grease. For waste streams with oil and/or grease applications (non-synthetic), blends with pseudomonas are preferred. In addition, pseudomona putida has been shown to act as an aerobic denitrifier. Using this blend for your treatment can reduce the load on your denitrification plant, or eliminate it completely. Bacillus blends are available in 1, 5 and 10 billion colony forming units per gram; or 1×108 CFU's, 1×109 CFU's, and 1×1010 CFU's. Blends with pseudomonas are available in 1 and 5 billion CFU's only; or 1×108 CFU's and 1×109 CFU's.
What is the most cost effective solution for bacterial symbiosis?
If you can adequately control dosing with staff, or with the use of a volumetric doser, the highest strength bacteria is the most cost-effective solution. This option also allows you to use a pseudomona blend if you have oil and grease, or need to aerobically denitrify.
Is pseudomona putida aerobic?
In addition, pseudomona putida has been shown to act as an aerobic denitrifier. Using this blend for your treatment can reduce the load on your denitrification plant, or eliminate it completely.
What are the common protozoa in wastewater?
Common Protozoa in Wastewater. In wastewater treatment systems where there is a low load and high sludge retention time the presence of protozoa such a ciliates, flagellates , and amoebae is very common. These eukaryotic organisms are able to feed on particulates, such as suspended bacteria. It is generally assumed that protozoa's primary role in ...
What is a wastewater treatment microscope?
A wastewater treatment microscope can be used to identify a number of different organisms during the water treatment process. Below is a guide to identifying these organisms and a few notes on what the organism identification might indicate.
What is metazoa in wastewater?
As a wastewater treatment system matures, dissolved oxygen concentrations eventually rise to levels that can support multicellular lifeforms. Unlike bacteria (prokaryotes) and protozoa (eukaryotes) which are all single cellular organisms, metazoa are more complex organisms with differentiated cells.
What is the role of protozoa in wastewater treatment?
It is generally assumed that protozoa's primary role in wastewater treatment is the clarification of the effluent. The US Environmental Protection Agency defines effluent as discharge of liquid waste from a wastewater treatment facility, factory, or industry to a local water body.
What are nematodes in a floc?
Nematodes aid the floc with oxygen utilization. They are commonly found in healthy attached growth systems and are indicative of poor operating conditions if they are found in activated sludge systems.
What is an amoeba?
Amoeba (protozoa) Amoeba are slow moving single celled protozoa. With streaming cytoplasm, amoebae envelop free bacteria, organic particles, and other food sources. In wastewater, you can often find free amoeba which are just the streaming cytoplasm inside a cell envelope.
Can amoeba be found in wastewater?
In wastewater, you can often find free amoeba which are just the streaming cytoplasm inside a cell envelope. Additionally, in wastewater the presence of heavy metals can result in dispersed growth of floc structures and it is recommended to check and see if Arcella are present.

Why is the Puget Sound wastewater system disabled?
Meanwhile the primary system — where wastewater is usually screened of trash and grit and settled to drop out a portion of the solids — is disabled. Because of damage to pumps, motors, electrical panels and more, the plant is only screening out trash, minimally settling the incoming flow, and disinfecting and dechlorinating the wastewater before discharging it into Puget Sound from the plant’s deep-water outfall.
How much water did the sewage plant dump into the Sound?
On three days of heavy rain last month, the plant dumped about 235 million gallons of untreated waste water straight into the Sound, including 30 million gallons of raw sewage.
Why are the bugs starving?
The flood took out boilers that heat the digesters, so the bugs have been cold. It also killed the pumps and other equipment that carries the sludge that is the bugs’ food to the digesters. So the bugs are starving.
What happened to West Point wastewater treatment plant?
The West Point treatment plant was disabled in a disastrous flood Feb. 9 causing the plant to release hundreds of millions of gallons of raw wastewater over the course of three events into Puget Sound. (Steve Ringman/The Seattle Times) Environment. Local News. Puget Sound.
When will the water treatment plant be back in operation?
The soonest it will be back in normal operation — after tens of millions of dollars in repairs — is April 30 , county wastewater managers say.
Where are the pipes covered in sludge?
Pipes are covered in a sludge mixture at the West Point treatment plant last month. (Johnny Andrews/The Seattle Times)
Can bugs be revived in West Point?
But right now, the bugs are suffering with little food or heat since the flood. They must be revived before the plant can be put back into normal operation. That’s not an easy task, and West Point has had problems for the past year and a half — long before the flood crippled the plant.
How to remove soluble compounds from wastewater?
Biological treatment is the most efficient way of removing soluble compounds from wastewater. Until recent times, it was functionally the only way. Biological treatment is far more efficient and available than processes like ultrafiltration and reverse osmosis and has been used for centuries. It’s the primary mechanism for lagoon treatment and provides for true removal of BOD without creating sludge. While some will end up in biomass, the majority of carbonaceous BOD is converted to carbon dioxide and off-gases to the atmosphere. There are very few processes that allow removal that simply and efficiently without having to handle waste products.
What is free floating bacteria?
Free floating: These bacterial cells are Lone Rangers: each on its own floating around in the water column. Because they are not likely to settle over time, they can contribute to TSS in the effluent .
What is the advantage of floc forming bacteria in a lagoon?
Their advantage in a lagoon is that those flocs are large enough to settle out. They eat the BOD and then when they’re done the particle is large enough to sink as sludge and not go out as TSS.
Which autotrophs nitrify ammonia?
The autotrophs we discuss most frequently are those that nitrify, or consume ammonia: namely Nitrosomonas and Nitrobacter. While there are other species of nitrifying bacteria, these are the two that are most researched and most productive.
Who is the lagoon microbiologist?
Lagoon Microbiology: Meet Your Bugs is the first webinar presented by lagoon specialist Julie Hartwig. Julie knows her stuff: She has a BS in Civil Engineering from the University of Illinois at Urbana-Champaign, a master’s in Environmental Engineering from Penn State, and hands-on experience in wastewater troubleshooting as a rep for a major water technology company.
Do heterotrophs kill BOD?
There are many types of BOD-eating heterotrophs, but they’re all robust, hard to kill, and quick to reproduce. They’re also very adaptable to changing conditions. If conditions in the lagoon favor one species of heterotrophic bacteria over another, that species will just reproduce faster to take advantage of those conditions.
Why is wastewater important?
Our waste provides the food for the microbes in activated sludge. They play a critical role in water purification and are thus important contributors to the maintenance of public health — not to be taken for granted. Without these sophisticated wastewater treatment processes, we would be at risk of contracting numerous water-borne infectious diseases.
What is activated sludge?
The by-product is called “activated sludge,” and is composed of a biotic soup of bacteria, protozoa and other microbes called “mixed liquor.” (The activated sludge process, developed in Britain 100 years ago, arose from work at the Lawrence Experiment Station in Massachusetts. This was one of the most important contributions to improving environmental and public health in the 20th century.) Secondary treatment relies on these microbes to eat the remainder of the waste or organic material.
What is the creepiest thing in the world?
The creepiest and largest creatures were the annelid (segmented) bristle worms, with hairy, clear bodies constantly eating green algae — observable bits moving through their bodies with the pulsation of peristalsis — and expelled from their posterior, leaving behind a channel that marked their progress.
What organisms are responsible for degradation of organic materials?
Organisms responsible for degradation of organic materials in natural and human-designed systems are quite diverse, including bacteria, unicellular protozoans, ciliates, rotifers, amoebas and nematodes. Some are free-floating, while others attach their “foot” to substrates.
Why are microbes important to the environment?
All of them play a vital role in the breakdown of organic pollution in natural systems, and the biological processing of human waste, ensuring the purity of our water supplies both for ourselves and other species. So if ever you have the opportunity to peer through the lens of a microscope at a drop of water from a biological filter, or a pond, you will not be disappointed. Perhaps while you’re at it, you might want to say a word of thanks for all the work they do. It’s a small world after all!
What are the most difficult crustaceans to observe?
The most challenging to observe were cyclops or copepods — miniature crustaceans related to lobsters and crabs. They hastily darted away from the light of the microscope stage, making capturing their image an exercise in patience! I was, however, able to identify the adult and larval forms of a copepod known as Nauplius.
