  • Case Study: Mazzei AirJection® Aeration System Solves Odor And Nutrient Problems For California Carrot Packing Plant A carrot packing plant was having severe odor problems due to septic conditions in their truck washout water holding lagoon. In addition, nutrient and nitrogen levels were becoming an issue for land application of the wastewater for crop production. By Mazzei Injector Company, LLC
  • White Paper: Wastewater Lagoons - A New Aeration Concept
    White Paper: Wastewater Lagoons - A New Aeration Concept The use of wastewater treatment lagoons, or stabilization ponds, is a common practice for rural municipalities and industrial facilities. Through the years there have been numerous designs for these ‘sludge settling basins,’ ranging from facultative, partial aerated, and fully aerated systems. By Jim Dartez, RELIANT Water Technologies
  • Seepage Water Treatment: ZS Screw Blower Supplies Bacteria With Air
    Seepage Water Treatment: ZS Screw Blower Supplies Bacteria With Air In the seepage water treatment installation at the Münster waste management center, a screw blower from Atlas Copco supplies aerobic bacteria with air. The low-maintenance technology and the integrated frequency inverter were the deciding factors to use the energy-efficient ZS 55+ VSD.
  • Case Study: Aerator/Mixer System Gives China WWTP Trouble-Free Performance
    Case Study: Aerator/Mixer System Gives China WWTP Trouble-Free Performance Aeration Industries International, Inc. is playing a key role in cleaning up water worldwide to help preserve the earth’s most precious resource — water. When the Chinese city of Lin An planned an expansion to their oxidation oval system, officials were looking for a new type of aeration system that would offer process performance and trouble free operation. The company's AIRE-O2 TRITON® process aerator/mixers were the ideal solution for the Lin An wastewater treatment facility.
  • Case Study: Mazzei AirJection® Aeration System Installed In Alabama Field Erected WWTP A design/build contractor needed a quiet, efficient aeration system for a 250,000 GPD field erected WWTP. This plant was to be located adjacent to a school. A restriction on ambient noise at the location of the proposed WWTP required a quiet aeration process. By Mazzei Injector Company, LLC

ABOUT AERATION

 

A common first step in the secondary treatment process is to send wastewater to an aeration tank. In an aeration tank, bacterium is used to effectively break down pollutants into less harmful components. Wastewater aeration provides the appropriate oxygen level so that aerobic bacteria can thrive in degrading pollutants such as iron and manganese as part of the wastewater treatment process. Aeration can also be used to destroy anaerobic bacteria that perish in the presence of oxygen. Aerobes that can break down pollutants 10-100 times faster than anaerobes are used most frequently.

Aeration is also used to improve waste lagoons and other waterways such as lakes and reservoirs where oxygen deficiency contributes to taste, odor and pollutant problems. Equipment used for wastewater aeration includes low cascades, jet fountains, spray nozzles, blowers, submerged perforated pipe and porous plates or tubes. Whether the water is thrown into the air via a fountain or diffused by air bubbles being blown or drawn into the wastewater in an aeration tank, aeration works by increasing the area of contact between the oxygen in the air and water.

The most common wastewater aeration process in use today is the air diffusion process, where air is introduced from blowers through diffusion tubes suspended in a spiral flow tank, or in some cases, through diffuser plates in the bottom of the aeration tanks.
