  • Final effluent monitors protect wastewater treatment efficiency

    Southern Water operates 370 wastewater treatment plants (WWTP), many of which are unmanned for most of the time and most have numeric environmental permits, so a network of online monitors has been established to improve treatment and protect discharge compliance. This has involved the installation of final effluent monitors at over 300 sites in a programme that has lasted for more than ten ...


  • The Microbial Database for Danish wastewater treatment plants with nutrient removal (MiDas-DK) – a tool for understanding activated sludge population dynamics and community stability

    Since 2006 more than 50 Danish full-scale wastewater treatment plants with nutrient removal have been investigated in a project called ‘The Microbial Database for Danish Activated Sludge Wastewater Treatment Plants with Nutrient Removal (MiDas-DK)’. Comprehensive sets of samples have been collected, analyzed and associated with extensive operational data from the plants. The ...

  • Design and performance of full-scale iMBR plants treating winery wastewater effluents in Italy and Spain

    Abstract : This paper provides an overview of full-scale immersed membrane bioreactor (iMBR) technology applied to Mediterranean wineries. It is based on the cumulative experience on design, commissioning and operation of 8 Spanish and 13 Italian references from 2003 to present day. In all of them Kubota membranes are employed. Market drivers for this treatment technology in the wine industry and ...

  • The laminar/turbulent transition in a sludge pipeline

    Globally, wastewater treatment plants are under pressure to handle high concentration sludge in a sludge treatment line. Unawareness of the non-Newtonian behaviour of the thickened sludge has the potential to cause unexpected problems when the fluid behaviour changes from turbulent to laminar flow. In this study, sludge apparent viscosity was plotted as a function of total suspended solids ...

  • Use of online nutrient monitoring for automatic aeration and nitrate recycle pump control

    The Northside Wastewater Treatment Plant (WWTP) in Kinston, NC was expanded and upgraded in 2006 for biological nutrient removal (BNR) to meet limits of 3 mg/L total nitrogen (TN) and 1 mg/L total phosphorus (TP). In addition to the traditional approach of controlling the blowers based on dissolved oxygen (DO) readings, the City decided to implement an aeration basin blower control system using ...

  • Longer Life For Biofilters

    Biofilters are the odor control system of choice at composting facilities. Despite similar capital costs, the biofilters are generally less costly to operate than chemical scrubbers. The key to keeping operating costs in check, however, is to get the maximum use out of the biofilter media, thus avoiding the time and money needed to do media replacements. Allen Boyette, senior engineer and manager ...

  • The Light at the End of the Tunnel - How to Successfully Operate a UV Disinfection System

    ABSTRACTOver the past ten years, ultraviolet (UV) technology has become a commonly applied method of disinfecting of wastewater effluent. UV disinfection involves passing wastewater effluent through a confined chamber with rows of underwater lamps emitting UV energy. Viruses and bacteria become inactivated upon exposure to dosages of UV energy, thereby disinfecting the wastewater. The UV system ...

  • Blending microbes demands gentle touch

    Environmental-restoration product manufacturer requires fast, uniform, gentle blending of powdered microbes, enzymes and nutrients The microbial formulations that United-Tech, Inc. produces are used to break down or detoxify a broad array of complex, often-toxic organic compounds, greasy spills and other contaminants in a variety of ...
