  • 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 ...

  • 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 ...

  • 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 ...

  • A perfect pair: SBR designs & advanced aeration technology

    Conventional sequencing batch reactors (SBRs) that utilize diffused-air networks have existed in the U.S. for about three decades now. The reliability of controls and instrumentation has significantly improved in the last 10 to 15 years, and as a result, SBR plant designs are becoming more widely accepted. The attractiveness of their compact layout and ease of operation has also helped increase ...

  • A new Technology for Composting: Suction Aeration for Opening Composting Works

    Cost-efficient solution for smell emission reduction The enormous waste quantities that are produced day by day are one of the most difficult problems for the economy as such, for cities and communities and for private households. Storage capacities for waste are scarce everywhere. Therefore solutions of all kinds that reduce waste quantities or recycle waste materials to be reused in the ...

  • Why does modern aeration technology make the treasurer happy?

    The aerzen combined system provides optimum efficiencies at the wallau wastewater treatment plant The combination of different technologies for air conveying enablesoptimal energy use of oxygen for biological degradation processes in wastewater treatment plants. Concrete savings resulting from the use  of AERZEN machines demonstrate this in practice at the Wallau plant.  In 2016, ...

  • Effects of the combination of aeration and biofilm technology on transformation of nitrogen in black-odor river

    Excess nitrogen in urban river networks leading to eutrophication has become one of the most urgent environmental problems. Combinations of different aeration and biofilm techniques was designed to remove nitrogen from rivers. In laboratory water tank simulation experiments, we assessed the removal efficiency of nitrogen in both the overlying water and sediments by using the combination of the ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Cardiff WWTW aeration optimisation through scientific control

    Aeration optimisation of a 16 basin SBR plant running in ICEAS (Intermittent Cycle Extended Aeration System) mode was under taken by changing the operating parameters from the traditional design of dissolved oxygen (DO) control to a scientific approach using respirometry. Measuring the critical oxygen point for carbonaceous and nitrification bacteria and combining this with in-situ Oxygen Uptake ...

  • Significant Improvements in Biofilter Performance for H2S and VOC Removal Using Biotrickling/Bioscrubber Technology in the Aeration Distribution Plenum System

    ABSTRACT Biofilters can handle the removal challenge of a diverse mix of complex odors and VOCs. However, there are significant limitations in handling levels of hydrogen sulfide (H2S) loadings above 10 ppm. High levels of H2S loading in biofilters will create an increase in the acidithiobacillus colony causing an overproduction of acid. This will destroy all other biodegrading ...

  • 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 ...

  • The influence of aeration on the change in corrosiveness and aggressiveness of groundwater

    A high concentration of aggressive carbon dioxide disturbs many technological processes in water treatment. It also causes the development of corrosion in steel and concrete. De-acidification of groundwater by means of air bubbles alters pH and the concentration of aggressive carbon dioxide. This was investigated for the variables of air flow (Q = 20–50 L h−1) and height of water ...
