Aeration Process In Water Treatment Plant

Aeration is an activated sludge process promoting microbial growth in the wastewater.

Aeration process in water treatment plant. Aeration is the most critical component of a treatment system using the activated sludge process. Aeration in an activated sludge process is accomplished by pumping air into the tank or lagoon. This process is most often an activated sludge process. The activated sludge process is the most common option in secondary treatment according to oxymem.

In municipal and industrial wastewater treatment aeration is part of the secondary treatment process. The removal of nutrients is critical because wastewater that is overly rich in nutrients can cause ecosystem imbalances if released into the environment. Natural aeration natural aeration is a type of both sub surface and surface aeration. Aeration is often the first major process at the treatment plant.

Proper aeration promotes the growth of microorganisms or microbes in the wastewater. It can also be used to remove volatile organic chemicals voc in the water. Aeration treatment consists of passing large amounts of air through water and then venting the air outside. The aeration process introduces oxygen into the co produced water which by nature lacks dissolved oxygen.

Aeration is the process of bringing water and air into close contact in order to remove dissolved gases such as carbon dioxide and to oxidize dissolved metals such as iron. Aeration is an important step in the process of treating wastewater including sewage effluent. Aeration brings water and air in close contact in order to remove dissolved gases such as carbon dioxide and oxidizes dissolved metals such as iron hydrogen sulfide and volatile organic chemicals vocs. Wastewater aeration is typically used during the secondary treatment process.

An ample and evenly distributed oxygen supply in an aeration system is the key to rapid economically viable and effective wastewater treatment. Microorganisms in aeration wastewater treatment tanks break down organic compounds and nutrients. Through the natural process of photosynthesis water plants release oxygen into the water providing it with the oxygen necessary for fish to live and aerobic bacteria to break down excess nutrients. The air causes the dissolved gases or volatile compounds to release from the water.

This process is performed by mixing up air and co produced water by either injecting air into water spraying water into the air agitating the water mechanically or allowing water to pass over an irregular water surface usepa 2010. A well designed aeration system has a direct impact on the level of wastewater treatment it achieves.
