The DO concentration remains high in the outside rings of the floc where nitrification occurs but low in the inner rings of the floc where denitrification occurs. This method is dependent on the floc size and characteristics; however controlling flocs is not well understood and is an active field of study [ 2 ]
The SHARON (Single reactor system for High activity Ammonium Removal Over Nitrite) wastewater treatment process is a combination of two already used nitrogen removing reactions. One process utilizes fast growing nitrifiers utilizing nitrification of ammonia to nitrite and Anammox which is the denitrification of nitrite to atmospheric nitrogen ...
Wolf Creek Wastewater Treatment Plant in Foley, Alabama [1] Aerobic granular reactors (AGR) or Aerobic granular sludge (AGS) are a community of microbial organisms, typically around 0.5-3mm in diameter, that remove carbon, nitrogen, phosphorus and other pollutants in a single sludge system. It can also be used for wastewater treatments.
Nitrification is the biological oxidation of ammonia to nitrate via the intermediary nitrite. Nitrification is an important step in the nitrogen cycle in soil. The process of complete nitrification may occur through separate organisms [1] or entirely within one organism, as in comammox bacteria. The transformation of ammonia to nitrite is ...
Furthermore, TR2 strains of P. sturzeri and Pseudomonas sp. strain K50 were also shown to have substantially low levels of nitrous oxide production in water treatment. [10] Thus enriching activated sludge for aerobic denitrifying bacteria can be effective in combating the global warming effects of nitrous oxide in wastewater treatment. [10]
The biological treatment of wastewater in the sewage treatment plant is often accomplished using conventional activated sludge systems. These systems generally require large surface areas for treatment and biomass separation units due to the generally poor settling properties of the sludge. Aerobic granules are a type of sludge that can self ...
In early 2013, the wastewater treatment plant was renamed the San José–Santa Clara Regional Wastewater Facility, though it retained its former name for legal purposes. [1] A $114 million cogeneration facility was completed in August 2020, featuring a façade by Buster Simpson that is illuminated at night. [7]
A project to expand the plant's wastewater treatment capacity by building new facilities is expected to begin in late 2024. [3] The 740-million dollar project is expected to increase the facility's ability to purify wastewater by about 20 millions gallons per day, enough to supply an estimated 250,000 people per day with drinking water.
