  • ECS compost aeration floors - the foundation of aerated compost system design

    Inventive minds have come up with an amazing number of variations to channel air through a floor and into, or out of, a compost pile. Designs that have been based on sound engineering calculations and experience have generally worked. However, since all aeration floors are constrained by physics and Murphy, the floors that were less rigorously designed have not faired well. The characteristics by ...

  • The principles of aeration and mixing utilizing process aerator technology

    Aeration and mixing are necessary elements for aerobic biological wastewater treatment processes to maintain a healthy, stabilized biological population and thus, insure optimal treatment of the wastewater assuming there is adequate contact time and substrate available. In the design of wastewater treatment plants, aeration typically involves supply of both oxygen and mixing. Aeration is a large ...

  • Choosing Aeration Blowers

    Introduction Infrastructure spending in the United States has not kept pace with the population growth and many wastewater treatment plants are at peak capacity. The nation's wastewater systems and their ratepayers face a major challenge in funding the expansion, replacement, and maintenance of aging infrastructure over the next several decades. For this reason, plant engineers and ...

  • Fighting Foam in Aeration Tanks

    Just like a poorly poured pint of beer can wreak havoc on your coffee table, excessive foam formation in aeration tanks can create operational challenges for both municipal and industrial treatment plant operators.  In municipal plants, foam formation is common during secondary treatment startup, as the young microbiology is unable to breakdown surfactants associated with soap, shampoo, ...

  • Tracer studies on an aerated lagoon

    The city of Palmerston North, New Zealand, has two aerated lagoons as its secondary treatment facility. Interest about treatment efficiency led to an investigation into the hydraulics in the second lagoon to determine if further optimisation was viable. A tracer study using rhodamine WT was undertaken to ascertain the stimulus response output. Samples were also taken at 24 points within the ...

  • Solar septic tank aeration

    Bacteria are what enable wastewater to be treated and safely disposed off. This applies to home septic systems as well as municipal sewage treatment plants. The treatment difference between the two systems is the amounts of bacteria involved. A home septic system uses the same three types of bacteria aerobic, facultative, and obligate anaerobic. Aerobic bacteria require oxygen induced ...

  • Vortex in baffled surface aerator

    Baffled surface aerator and mixing tanks are different on the basis of the rotor placement. In mixing tanks, rotors are placed very deep in the tank, thus vortex creation can be prevented by placing the baffles. By definition, rotors are placed at or near the surface of water in surface aeration systems; complete prevention of vortex creation cannot be achieved by installing the baffles. Vortex ...

  • Sustainable wastewater aerator system built for generations

    When building a wastewater treatment facility 26 years ago, officials in the village of Theresa, Wis., decided on an oxidation ditch design and chose Aire-O 2 aspirator aerators based on their flexibility and energy efficiency. Today, several of those aerators are still in use and the treatment facility operates at even more efficient standards using a new line of the "next generation" Aire-O 2 ...

  • Efficient aeration system boosts energy savings

    A new efficient aeration system saves the Ontario, Ore., wastewater treatment facility $47,000 annually in energy costs. Besides giving this community a financial boost, the new system netted additional equipment cost savings by cutting aeration horsepower by more than half at the plant. The environmentally conscious city, located in the Oregon/Idaho border area, is meeting all of its effluent ...

  • What are the parameters of an extended-aeration activated-sludge system?

    The activated sludge process is the most widely used biological water and wastewater treatment. As is well known, by its means, suspended-growth microorganisms are applied to breakdown wastes. Aeration, the mixing of air and a liquid, is the means used to speed the reactions involved. Aeration methods include spraying the liquid into the air; diffusing air into the liquid or agitating the liquid ...
