What are the different types of wastewater treatment equipment?
Which of the following components of a wastewater treatment plant is designed to facilitate the decomposition of organic material by aerobic microorganisms? Aeration tank. Only about ___% of the entire world's water is directly available for our use. 1.4. Oxygen sag curves.
What is mechanical wastewater treatment?
grit chamber: a chamber or tank used in primary treatment where wastewater slows down and heavy, large solids (grit) settle out and are removed influent: wastewater flowing into a treatment plant lagoons (oxidation ponds or stabilization ponds): a wastewater treatment method that uses ponds to treat wastewater.
Aerators, mixers, decanters and rental equipment
Based on more than 20 years of experience, ATB WATER develops and manufactures the core components for biological wastewater treatment in-house at various locations in Germany and Romania.
AERATOR
AATB offers almost the entire range of aeration technology in the field of wastewater treatment.#N#You will find a wide range of design variations and sizes of a wide variety of aerators:
Mixer
Mixers and agitators from ATB homogenize the tank contents and prevent sediments from depositing on the bottom of the tank..
Decanter
ATB-CWE decanters are used to remove the near-surface clear water layer at the end of a treatment cycle in an SBR plant.
Rental equipment
In many applications, you as a customer are faced with the problem that no exact design data is available or that you only need an interim solution. For these applications, ATB also offers the option of using aerators, mixers or decanters within the framework of a rental agreement instead of purchasing the equipment.
What are the compounds that are released into the environment from wastewater?
Nutrients . Nutrients are compounds that when released into the environment from wastewater can cause and imbalance of growth of undesirable organism in the environment. Many “blooms” of noxious algae in freshwater for instance are caused by the release of the nutrient phosphorus.
What is the BOD in wastewater?
The goal of wastewater treatment is to reduce the BOD in the treatment process before it reaches area where other organism live. A very typical BOD level in household wastewater is 200 mg/L. This means that over five days under specific conditions (defined by the Standard Method) one liter of the wastewater will consume 200 mg of oxygen in the process of breaking down.
What is TSS in sewage?
Total Suspended Solids (TSS) is the amount of solids that are suspended in wastewater and are of a specific size. When released directly into the surface water environment, suspended solids can be responsible for a variety of problems including smothering habitat, carrying pathogenic organisms, clogging fish gills, smothering fish eggs and more. When released from a septic tank in high quantities, TSS can prematurely clog leachfields. TSS can be either organic (fine particle of food or feces) or inorganic like silt and clay. A high TSS value in wastewater is usually associated with a high BOD and indicates that it is to a great extent organic.
What is a TSS?
Total Suspended Solids (TSS) is the amount of solids that are suspended in wastewater and are of a specific size. When released directly into the surface water environment, suspended solids can be responsible for a variety of problems including smothering habitat, carrying pathogenic organisms, clogging fish gills, smothering fish eggs and more.
What is a CEC?
Contaminants of Emerging Concern (CEC) More recently, a broad class of compounds comprised of pharmaceutical products, personal care products, fire retardants, hormones and others are receiving attention due to their ability to impact aquatic organism at very low (parts per trillion) levels.

Total Suspended Solids
- Total Suspended Solids (TSS) is the amount of solids that are suspended in wastewater and are of a specific size. When released directly into the surface water environment, suspended solids can be responsible for a variety of problems including smothering habitat, carrying pathogenic organisms, clogging fish gills, smothering fish eggs and more. When released from a septic tan…
Pathogens
- Pathogens are organisms or viruses that are capable of causing disease. The amount of actual pathogens in wastewater will depend on its origin. When we have a bacterial or viral infection or if we are the host of a certain parasites, we will shed them in our feces and contribute them to the wastewater. Since it is very difficult to test directly for the majority of pathogens, public health of…
Nutrients
- Nutrients are compounds that when released into the environment from wastewater can cause and imbalance of growth of undesirable organism in the environment. Many “blooms” of noxious algae in freshwater for instance are caused by the release of the nutrient phosphorus. Some fish kills and habitat modification in marine environments are caused by excessive release of nitroge…
Contaminants of Emerging Concern
- More recently, a broad class of compounds comprised of pharmaceutical products, personal care products, fire retardants, hormones and others are receiving attention due to their ability to impact aquatic organism at very low (parts per trillion) levels. Collectively these compounds are called Contaminants of Emerging Concern (CEC). Perhaps the most documented effect of these comp…
