  • Aeration upgrade

    The community of Moscow is located in the northeast corner of Pennsylvania, approximately 10 miles southeast of Scranton. The current WWTP consists of an activated sludge system with three oxidation ditches in parallel operation. The total volume of all three ditches is 0.372 million gal per day (mgd), while the average size of each ditch is 180 ft by 24 ft by 6 ft deep. Previously, two of the ...

  • Collection system aeration and the microbial benefits

    In late 2015 Reliant Water Technologies introduced the Wet Well Wizard, an aeration tool for the wet wells in collection systems. During 14 months of field testing the patent pending Wizard System, the primary objectives were to eliminate FOG (fat, oil and grease) caps and to reduce H2S, eliminating it if possible. All trials were proven excellent with very few changes to the product that ...

  • Achieve Performance Requirements by Combining Surface Aeration with Diffused Aeration Systems

    Aeration Industries International’s Aire-O2 Triton® can bring a struggling diffused air basin back up to speed quickly by adding oxygen capacity. Benefits of combining Aire-O2 Triton Aerators and Diffused Air Systems: Instant capacity (SOTR) increase without the need to interrupt production or drain the basin Increase aeration efficiency (SAE) with consistent ...

  • 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 ...

  • 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 ...

  • Aeration control – a review

    This review covers automatic control of continuous aeration systems in municipal wastewater treatment plants. The review focuses on published research in the 21st century and describes research into various methods to decide and control the dissolved oxygen (DO) concentration and to control the aerobic volume with special focus on plants with nitrogen removal. Important aspects of control system ...

  • 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 ...

  • The role of aeration in water features

    In warm weather, the surface of your lovely water feature sucdenly develops a green, slimy mass which looks as if it may begin to pulsate, eave the water, and threaten the surrounding countryside, like the monstrous entity in some early Steve McQueen B movie Your instinct may be to use extreme measures - the chemical equivalent of calling in the National Guard for a tactical nuclear strike. ...

  • 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, ...

  • Regenerative Turbine Aeration Technology

    In order to acquire precise control of input and output fluid/gas parameters, wastewater managers and technicians can utilize a regenerative turbine pump, which fully optimizes the gas dissolution process that properly treats wastewater, time after time. Once such parameters have been completely controlled, a well-designed wastewater treatment system should be able to initiate all necessary ...

  • 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 ...

  • Alpha Factors in Full-Scale Wastewater Aeration Systems

    ABSTRACTSurface active agents depress gas transfer at gas-liquid interfaces. They are present as measurable trace contaminants at all environmental and at most industrial gas-liquid interfaces. This paper presents the results of several studies, including lab and full scale studies that show the depression of gas transfer, usually quantified by the alpha factor, can be related to the Reynolds ...

  • Aeration system improves mixing, oxygenation, & maintenance

    When its brush rotor system failed, the city of Franklin, LA, dccidcd to replace it with an Airc-02 Triton aeration/mixer system, which about equaled the ongoing costs of refurbishing die rotors. The aerators met all the city's needs and a year later, city officials purchased more of the aerators for its second ditch. Back in 2000, Franklin's wastewater treatment plant consisted of an activated ...

  • Aeration boosts USA’s largest lagoon system

    The city reports, 'The entire aeration system has surpassed all our expectations.' Problem In 1989, a growing population prompted this northwestern USA community to expand the efficiency and capacity of its wastewater treatment facility. The original unaerated lagoon system had been built in 1967 and had worked adequately for many years. But, the system needed additional treatment ...

  • Fault detection and isolation of sensors in aeration control systems

    In this paper, we consider the problem of fault detection (FD) and isolation in the aeration system of an activated sludge process. For this study, the dissolved oxygen in each aerated zone is assumed to be controlled automatically. As the basis for an FD method we use the ratio of air flow rates into different zones. The method is evaluated in two scenarios: using the Benchmark Simulation ...

  • 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 ...
