  • 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 ...

  • Seasonal influence of environmental variables and artificial aeration on Escherichia coli in small urban lakes

    This study investigated patterns of Escherichia coli in urban lakes in Lubbock, Texas. Specific objectives were to (1) document seasonal patterns in abundance of E. coli over a 3-year period, (2) identify environmental factors, including effects of migratory geese and artificial aeration devices that may influence E. coli abundance, and (3) determine if ...

  • 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 ...

  • 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 ...

  • Real-Time Control Optimizes Extended Aeration Processes

    The population of Hillsborough County, Florida has doubled since the Valrico advanced wastewater treatment plant (AWTP) was built in 1990 to treat the sewage of several small communities west of the City of Tampa. When it began operation, the Valrico AWTP capacity was only 4 MGD; small when compared to Tampa's 96 MGD Howard F. Curren AWTP located not far to the east. But Valrico serves as a very ...

  • The most reliable oxygen meter for the aeration tank

    In a direct comparison with a conventional O2 probe, the new HACH LANGE LDO probe took part in a ➔ trial at the sewage treatment plant for a period of nine weeks. The LDO technique proved its worth by the superior quality ofthe results and its easy handling. In particular, it excelled in terms of the extremely small amount of probe fouling. At the A stage of the Nieuwveer sewage treatment ...


  • 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 ...

  • Supplier profile: Aeration Industries Int’l. Inc.

    Pollution Engineering recently spoke with Aeration Industries co-founder and President Dan Durda. Mr. Durda co-founded the company, which celebrates its 30* anniversary this year, with his father, Joseph Durda, in Minneapolis, Minn. Known as the land of 10,000 lakes, a healthy fish population was very important to in-state residents. The company's first products were thus designed to reduce the ...

  • Sewage Treatment – Small System in a Watershed

    ABSTRACT:Water purveyors, in examining their watersheds, have raised concerns over small community pollution sources, particularly over phosphorus, nitrogen, pathogens and suspended solids. As our population has increasingly moved further upstream in watersheds, the application of classic sewage treatment plants (STPs) have been pushed to their limit of design, especially in light of the need by ...

  • Hawaii: Shrimp & fish consultant predicts aeration change

    The term 'aeration' will change to include its equally important counterpart, circulation, predicts a leading aquaculture consultant in Hawaii. His years of experience include extensive to intensive cultivation of many species: P. vannamei, P. strylirostris and P. monodon shrimp; freshwater prawn Macrobrachium rosenbergii; oysters; and both freshwater and saltwater fish. 'Destratification of ...

  • LEVAPOR carrier in small sewage treatment plants

    The application of LEVAPOR carrier results in advantages also in small sewage treatment plants for 4 to 20 inhabitants. In such plants subsequent immobilisation of biomass resulted in Efficient and stable nitrification even at 10-13°C, Doubling of removal rates Lower excess sludge production and Lower outlet COD ( 45 to 65 mg/L at 1,4-1,8 kgCOD/m³x day) ...

  • Actively aerated methanobiofilters to control methane emissions from landfills

    Methane (CH4) capture at sanitary landfills for energy recovery is capable of reducing the impact of CH4 on the global atmospheric carbon budget. However, gas capture may only be viable where gas quantities are high enough to warrant economical energy production. Considering the potential global warming impacts, there is a need to ...

  • Comparative analysis of extended aeration and Fenton process in landfill leachate treatment

    This research is undertaken to investigate various operating conditions for minimising sludge disposal and maximising chemical oxygen demand from leachate. With conventional extended aeration process the optimum removal of COD and colour were 36% and 24% respectively. In Fenton process, for optimum pH of 5 and optimum H2O2/Fe ...

  • The effect of BOD5 and flow-rate of activated sludge systems on investment and energy costs

    In this study of wastewater treatment, the effect of flow-rate, BOD5 and other design parameters (MLSS, mean cell-residence time, etc.) on aeration tank dimensions, investment amount and energy cost has been investigated. The relations among these parameters are represented with mathematical equations, which could be useful in new plant design and in the estimation of investment and energy ...

  • Robust decentralized wastewater treatment for small communities…FAST®

    For many small and medium communities, centralized or conventional sewer options are technically complicated and/or are often the expensive choice for managing wastewater treatment. As the demand for water reaches critical levels for most areas around the world, decentralized treatment systems are becoming increasingly popular by returning treated water back to the local environment.  ...

  • EPA award winner says Aeration Industries helped achieve it!

    ' Since 1986, the AIRE-O2® aerators have operated 24 hours a day…and seven aerators have required no new parts replacements! ' Problem Although this is a relatively small Midwestern USA town, the surge of summer-time tourists posed special challenges to the municipality’s wastewater treatment system. The flows tripled from 0.2 MGD (757 m 3/day) to 0.6 MGD (2271 m 3/day) into its aerated ...

  • Experimental evaluation of intermittent aeration of a hollow fibre membrane bioreactor

    Intermittent membrane aeration provides a substantially improved energy efficiency in hollow fibre-based immersed membrane bioreactors (HF iMBRs). The benefits of intermittent aeration have been assessed with respect to sustaining a target flux and/or limiting the fouling rate to a sustainable level based on a small plant using full-scale HF modules. Results show that for the same specific ...
