  • Improving Efficiency and Reducing Energy and Maintenance Costs in Aeration Systems

    Energy costs for operating an aeration system in a biological wastewater treatment plant often times exceeds 75% of the total energy costs for the plant. Adding in blower and diffuser maintenance costs, Aeration Systems are easily the most costly portion of the treatment process, many times consuming so many resources that other parts of the plant may not be properly maintained or operated. By ...

  • Assessment of diffuser pressure loss on WWTPs in Baden-Württemberg

    Aeration of activated sludge is a critical treatment step for the operation of activated sludge plants. To achieve a cost effective treatment process, assessing and benchmarking of aeration system performance are important measures. A simple means of gauging the relative condition of a fine bubble diffused aeration system is to evaluate the pressure loss of the diffusers as oxygen transfer tests ...

  • Coarse Bubble Diffusers

    Coarse bubble diffusers are suitable for almost any type of water and wastewater application. The primary application of coarse bubble diffuser systems today are as indicated below: Aerobic Digestion Applications Coarse bubble diffusers have been the traditional diffusers used in these applications. The standard design rate for this application is 30 scfm per 1000 ft of tank volume. ...

  • Modelling a full scale membrane bioreactor using Activated Sludge Model No.1: challenges and solutions

    A full-scale membrane bioreactor (1,600 m3 d−1) was monitored for modelling purposes during the summer of 2006. A complete calibration of the ASM1 model is presented, in which the key points were the wastewater characterisation, the oxygen transfer and the biomass kinetics. Total BOD tests were not able to correctly estimate the biodegradable fraction of the wastewater. Therefore the wastewater ...

  • Maximum Air Pressure for Diffusers

    In the water and wastewater treatment field there are many needs and/or opportunities to upgrade existing facilities or to construct new facilities where space is limited. The available space can severely constrict the capacity of treatment facilities, or reduce the options available for design and implementation of the treatment process. Some of the needs facing many potential facilities is the ...

  • Innovative system reduces ammonia at Hawick Sewage Treatment Works

    Hawick Treatment Works has reduced its ammonia discharge thanks to an innovative aeration system installed by market leaders Suprafilt. Aeration experts Suprafilt designed a highly efficient system using MF1100 plate diffusers, which increased the amount of oxygen to the site providing an instantaneous reduction in ammonia levels. The company, who are market leaders in designing and ...

  • The MBBR Sewage Plant: The WHO, WHAT, WHEN, WHERE, WHY, and HOW

    If you are researching biological water treatment methods and which one could be the best for your application, perhaps you’ve come across moving bed biofilm reactors (MBBR). You probably have a few general questions as to how it works and how it can help you meet your particular company or municipalities wastewater treatment needs, but are having a hard time finding answers while searching ...

  • BM respirometry study about nitrification inhibition and actual aeration capacity in an activated sludge process case study

    Study for municipal WWTP in Spain This study is ordered to SURCIS as a consequence of the low process performance, practical absence of nitrification treatment. By other side, the mixed-liquor presented some abnormal features such as weakness, dark colour and abundant white foaming. Data for study interest Aeration system: fine bubble diffusers + liquid oxygen injection Ammonium ...

  • Fine Bubble Aeration

    Fine bubble aeration systems are inherently more efficient in oxygen transfer than coarse bubble aeration systems. Overall, a fine bubble aeration system configured in a grid configuration will operate at approximately 50% the energy consumption of coarse bubble systems. Because of this high operating efficiency and corresponding reduction in energy consumption, fine bubble aeration systems have ...

  • The CaroMont Health Ozone Laundry System

    Abstract Ozone generating equipment was retrofit into the laundry washroom of the Gaston Memorial Hospital in Gastonia, NC, and began operating in the early part of July, 2010. Three ozone generating systems service six washer-extractors in the washroom. The performance of this fine-bubble ozone diffusion laundering system has been monitored since that time, with various adjustments made to ...

  • Floating HDPE Air Lateral System Cuts Blower Requirement in Half, Improves DO, and Removes Odor at F&A Dairy Plant

    Project History F&A Dairy, founded in 1958, began manufacturing cheese at their Dresser, Wisconsin facility in 1974. Five years after the plant’s opening, F&A Dairy constructed an aerated lagoon Waste Water Treatment Plant (WWTP) with land irrigation, employing a static-tube coarse-bubble aeration. The system was originally designed to process approximately 3,000 ppd BOD. The ...

  • Brakebush brothers inc. Westfield, WI - Case study

    The private wastewater treatment facility at Brakebush Brothers Inc., a chicken products manufacturing plant, was doing a great job removing breading and other by-product solids from waste flows. But the rural plant— a “further processing” (post-butchering) facility—produces uncommonly heavy loads of fats, oils and grease (FOG) that were taxing the aerobic treatment ...

  • IDEAL Lagoon Based Extended Aeration System with Batch Reactor Process Doubles Treatment Capacity at Grantsville WWTP

    Originally designed for a 0.75 MGD capacity, the Grantsville Wastewater Treatment Plant receives residential wastewater from almost 10,000 residents in Grantsville, Utah, just west of Salt Lake City. In 2009, the plant was having significant trouble meeting the city’s discharge requirements for ammonia, TSS, and BOD. According to Ron Griffin, the plant’s operator, treated wastewater ...

  • Surface Aeration or Diffused Aeration

    When designing lagoon aeration systems selection of optimum aeration components is critical to maximum performance, long-term operation and easy maintenance. Lagoon aeration is generally broken down into two major categories surface aeration and diffused aeration.
