What is Atad sludge treatment?
Autoheated Thermophilic Aerobic Digestion (ATAD) is for more than 30 years the sludge treatment process of choice for mid-sized wastewater treatment plants, especially under the aspect of the future regulations, as for example in Europe. FUCHS-ATAD is a process providing for simultaneous stabilization and disinfection.
What is a sewage treatment plant?
A sewage treatment plant is designed and constructed to best suit the need of the facility; whether be industry, ships or regular sewers in urban cities. The sewer stored can be treated with mainly two major ways; chemically or biologically.
What is Atad technology and how does it work?
ATAD is a technology widely applied in Europe since the 1970s and more recently in North America. The major advantages of ATAD over conventional aerobic digestion processes are: • Significantly reduced SRT (5 to 8 days) to achieve a volatile solids reduction of 40 to 50%
How is sludge discharged from a sewage treatment plant?
The heavier sludge and other sewage particle is separated of the light water; which is then discharged overboard. Due to strict rules and regulations regarding the quality of water allowed to be discharged from sewage treatment plant.
Are biosolids safe?
Biosolids are one of the most studied materials that have ever been regulated by the U.S. Environmental Protection Agency (USEPA). Decades of studies have demonstrated that biosolids can be safely used for the production of crops.
What is autothermal thermophilic aerobic digestion?
Autothermal thermophilic aerobic digestion (ATAD) is a microbial fermentation process characterized as a tertiary treatment of waste material carried out in jacketed reactors.
What is the ATAD process?
ATAD (autothermal aerobic thermophilic digestion) is a liquid composting, tertiary sludge. treatment process which utilizes the metabolic heat generated by way of microbial digestion to stabilize. the treated sludge and effectively pasteurize the digestate [1–3]. This produces class A biosolids. suitable for land ...

What is Fuchs-Atad?
FUCHS-ATAD is a process providing for simultaneous stabilization and disinfection. With the ATAD organic solids are biologically degraded. This natural aerobic process releases energy, mainly in the form of heat, leading to thermophilic temperatures.
What is sewage treatment plant?
A sewage treatment plant is designed to treat and process raw sewage over different steps involving breaking, filtering, settling, controlled aerobic decomposition and chemical treatment. One of the most common things that come in our mind regarding human waste; is to dump it to the sewers and let the government take care of it.
How many crews are required to have a sewage treatment plant?
The law requires all ships and water vessels above 4000 Gross tonnage dead weight or carrying more than 15 crew / personal in international waters is required to have dedicated sewage treatment plant or sludge tank to hold sewage for appropriate time.
What is the process used to break down sewage into small parts?
The process used to systematically break the sewage into small parts; using biological and chemical method is known as sewage treatment.
What is chemical sewage treatment?
The preliminary chamber is equipped with coarse and fine mesh of screen as filters to remove large solid particles from getting into the system. In many designs it stay set at the top of the primary chamber with flow measurement device recording and filtering waste water inlet at the same time.
Why is activated carbon added to sewage?
It get on to absorb all the organic molecules associated with the smell and distinct colour. In many design the activated carbon sets are filled just after the settling chamber; thus allowing waste water to be treated before moved to next chamber.
Where does waste water go after biological treatment?
The waste water after biological treatment went to the settling chamber where the heavier solid particles settles down by effect of gravity. To further support the process and nullify effects of flow of sewage; the waste water is inserted into the chamber from chamber and exit from top to the next chamber.
Does sewage smell?
So yes all sewage treatment plant smell but the smell produced is contained within its wall; to ensure convenience and safety of the operating crew in the engine room. But in case you be require to open the manhole above the screen filter; be prepared for the sudden burst of foul smell.
