Wastewater - Aeration

Feature Installation: Pleasant Valley School District, PA (Wastewater Treatment Lagoons) Pleasant Valley School District is comprised of seven schools encompassing a 120 square mile area (311 km²) in Monroe County Pennsylvania.
Concrete Manufacturing Operation Meets Permit Requirements With PH Control System
In order to meet its discharge permit limits, a ready-mix concrete manufacturing operation needed to neutralize its high pH process water. Staff installed a control system that automatically detects a rise in pH and treats the water with a modular in-line carbon dioxide feed system. The operation can now recycle treated water for rinsing trucks, supply recycled water into the concrete batching operation, and safely discharge the water into the environment.
Case Study: Buxahatchee Chose Aqua Technologies For Its Small Footprint And Ability To Meet Stringent Nitrogen And Phosphorus Requirements The Buxahatchee Wastewater Treatment Plant in Calera, Alabama was built in 1960. It upgraded in 1985 to a 0.75 MGD capacity extended aeration system with integrated clarifier and traveling aeration bridge for nitrification.
Brewery Reuses Water For Factory Wash-Down
Looking to reduce its water footprint, Shepherd Neame Brewery invested in a complete membrane bioreactor (MBR) wastewater recovery and re-use plant. Learn how the new plant's aeration system has helped to reduce the brewery's water-to-beer ratio to an industry-leading value of 3:1.
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

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.
