  • 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. ...

  • Aeration and Stripping

    Aeration in the treatment of water is a process that is used for either of two purposes: either to add oxygen (or possibly another gas) to water (adsorption) or to remove an unwanted gas from water (desorption or stripping). It follows that aeration is most likely to be encountered in the treatment of ground waters. Aeration can be carried out in a variety of ways. The most appropriate ...

  • 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 ...

  • 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 ...

  • Aeration decreases THMs

    WITH HIGH LEVELS of trihalomethanes (THMs), the township of North Shore in Northern Ontario, Canada, explored treatment options at its Serpent River'Water Treatment Plant. The Serpent River treatment process includes slow-sand filtration. limestone contact tanks, and sodium hypochlorite disinfection. After filtration, sodium hypochlorite is injected into the treatment process before water enters ...

  • Aerator solution for WWTP

    IN 1990, CIRCUIT ENGINEERING began importing the Aire-02 Triton Aerators from the United States. With over 60 000 installations of the Air-02 Aerators currently in operation worldwide, Aeration Industries is one of the world's leading aerator companies. This month. Water&Sanitation Africa spoke to Ryan Beswick, director of Circuit Environmental Engineering, to find out more about these ...

  • 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 ...

  • Monitoring of typical pumps and aerator in a water treatment plant

    The wireless vibration network of Wi-care system consists of the communication between three components; the transmitter, the range extender and the receiver. The transmitter is fixed on the machine and transmits the vibration and the temperature data at the measurement point. The second element of the Wi-care wireless network is the range extender, its function is to transmit vibration and ...

  • 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 ...

  • China: Carp yields double with aeration

    In the mid-1980’s, the People’s Republic of China looked at semi-intensive cultivation to produce higher yields to provide a protein staple for its people and as an export product. Two government farms in Yunnan Province raising freshwater grass carp Ctenopharyngodon Idellus experimented with aeration. Production yields doubled from 200 kg per 0.06 ha to 500 kg at one farm with AIRE-O2® aerators. ...

  • Lagoon Aeration - Sleep Eye, MN

    Mazzei Aeration System Solves Lagoon Odors and High Maintenance Problems Sleepy Eye, MN The Problem: A large vegetable processing facility in central Minnesota was experiencing problems with its lagoon surface aerators. The company’s treatment process includes a collection and screening assembly, two anaerobic stabilization ponds and a 40 million gallon aerated lagoon. The aeration lagoon ...

  • 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 ...

  • DAF Regnerative Turbine Aeration Technology

    Gas is dissolved into a fluid through pressure in any DAF application.  The regenerative turbine pump applies pressure through a triple action force (centrifugal, axial and friction) to the gas and fluid during a single pass through the pump head.  Whether disolving compressed or atmospheric air, nitrogen or other gases to the fluid, the regenerative turbine pump achieves the highest ...

  • 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. But the primary reason for these systems is to utilize relatively shallow earthen ponds, or ...

  • Oxygen Transfer in a Biological Aerated Filter

    The City of San Diego (City) operates the Point Loma Wastewater Treatment Plant (PLWTP) which can normally treat up to 240 million gallons per day (MGD) of chemically enhanced primary treated (CEPT) effluent for ocean disposal. The City wanted to understand the performance capabilities of Biological Aerated Filters (BAFs) in treating CEPT effluent to secondary standards. To this end, the City ...

  • Aerators Enhance Aerobic Digestion Process

    The city of Eden,N.C.,operates an extended aeration process designed for an average flow rate of 13.5 mgd with a mixed liquor suspended solids concentration that typically checks in about 6,000 mg/l. This high biomass concentration is necessary to provide a well-settling sludge and good effluent quality. Further, the plant influent is approximately 40% domestic wastewater and 60% industrial ...

  • In the aeration tank, the turbo provides ventilation

    Robust in operation: at Emsbüren, the AERZEN turbo saves quite a lot of energy At Emsbüren wastewater treatment plant, Wasserverband Lingener Land invested in new blower technology for the aeration tank. In comparison with the old assembly, the turbo blower made by AERZEN saves between 100 and 200 kilowatt hours every day. Modernisation of wastewater treatment plants in order to ...

  • Recovery of reusable water from sewage using aerated flat-sheet membranes

    Continuous developments and advances in membrane technology allow recovering to large extent reusable water from untraditional water sources, such as municipal effluents. In this paper, operational results and preliminary cost-analysis of a microfiltration (MF) process used for raw sewage and secondary effluent polishing are given. The research was conducted with a 22 sandwich-type flat-sheet ...

  • Exploring aeration-associated energy savings at a conventional water reclamation plant

    Aeration accounts for a large fraction of energy consumption at conventional water reclamation plants (WRPs). Older plants were designed when control techniques were relatively primitive and energy consumption was less of a concern. As a result, although process operations at older WRPs can satisfy effluent permit requirements, they can operate with excess aeration. In this study, we developed ...
