  • 31% Energy Savings For Skanderborg Waste Water Treatment Plant With New 55 kW Atlas Copco ZS Blower

    With a savings goal set at 25 % for the Danish waste water industry, optimizing all parts of the operation, so even the aeration, is of the highest importance. In 2011, The Skanderborg Waste Water Treatment Plant replaced one of its 75 kW lobe blowers with a new 55 kW Atlas Copco ZS screw blower and were able to reduce their energy consumption with 31%.

  • Advanced Oxidation Processes: A.O.P. Whitepaper
    Advanced Oxidation Processes: A.O.P. Whitepaper

    Advanced Oxidation Processing is the generation and implementation of hydroxyl radicals (HO+) to oxidize contaminates in air and water. It is considered one of the most powerful oxidants readily available and it produces NO harmful by-products.

  • Top-Entry Agitators Keep Costs Low, Combat Pollution
    Top-Entry Agitators Keep Costs Low, Combat Pollution

    As the drainage basin to 85 million people, the Baltic Sea has faced considerable environmental strain for many years. Updated regulations to reduce levels of phosphorous and nitrogen prompted the Central Wastewater Treatment Plant in Saint Petersburg, Russia, to install new top-entry agitators in its aeration basins. By optimizing thrust and bulk flow, the updated plant now combats pollution by treating 400 MGD of wastewater while keeping energy costs to a minimum.

  • 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
  • Wastewater Plant Cuts Mechanical Aeration Run Time With Solar-Powered Circulation Technology In the Buckeye State, the village of St. Henry, OH, is bucking the trend of many rural farming communities. Instead of losing residents and local businesses to bigger cities, this community is growing. Local industries such as turkey processing are expanding as well. By: Michael Christensen, SolarBee, Inc.

Jet Aeration

Jet Aeration

The Mass Transfer Systems bi-directional jet aerators are designed with jet aeration nozzles installed on both sides of the liquid / air jet aeration manifold. This configuration is most applicable for square or rectanglular tanks, larger lagoons, and sequence batch reactors where directional flow patterns are not desired
PASSAVANT® Disc Diffuser ROEFLEX®

PASSAVANT® Disc Diffuser ROEFLEX®

The disc diffuser ROEFLEX® stands out for its simple and robust design. It consists of a unique, convex shaped support disc. The disc is covered by a flexible, slotted membrane of elastomer, a ring secures the membrane in place. Due to the disc’s unique convex shape the membrane is slightly lifted off the disc when air is supplied, therefore allowing an even distribution of the generated fine bubbles. The membrane can be delivered in different rubber (EPDM) qualities and slot patterns (HL, SL) according to the application.

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.
