Anaerobic Sewage Treatment Units
Anaerobic sewage treatment units are those units in which anaerobic decomposition of organic matter is used. These units are designed to treat sewage and wastewater that comes from domestic, commercial, and industrial sources.
Types of Anaerobic Sewage Treatment Units
There are different types of anaerobic sewage treatment units, which include the following:
1. Imhoff Tanks
Imhoff tanks are designed to treat sewage and wastewater that is rich in organic matter. These tanks are made up of two compartments, the upper compartment is for settling and the lower compartment is for digestion. In the upper compartment, the sewage settles and the solids settle to the bottom while the liquids rise to the top. In the lower compartment, the solids undergo anaerobic digestion, where microorganisms break down the organic matter and produce biogas.
2. UASB Reactors
Upflow anaerobic sludge blanket (UASB) reactors are designed to treat organic-rich wastewater. These reactors are made up of a cylindrical tank with a gas collection system at the top. The wastewater is fed into the bottom of the tank, and as it rises, it passes through a layer of sludge, where the organic matter is digested anaerobically by microorganisms. The biogas produced during the digestion process rises to the top and is collected in the gas collection system.
3. Anaerobic Filters
Anaerobic filters are designed to treat wastewater that is low in organic matter. These filters are made up of a bed of porous media, such as gravel or plastic, which provides a surface area for microorganisms to attach and form a biofilm. As the wastewater flows through the filter, the microorganisms in the biofilm digest the organic matter, producing biogas.
Conclusion
In conclusion, anaerobic sewage treatment units are an effective way to treat sewage and wastewater that is rich in organic matter. These units use anaerobic decomposition to break down the organic matter and produce biogas, which can be used as an energy source. The different types of anaerobic sewage treatment units include Imhoff tanks, UASB reactors, and anaerobic filters. Each of these units is designed to treat wastewater with different levels of organic matter.
