  • The incorporation of variability and uncertainty evaluations in WWTP design by means of stochastic dynamic modeling: the case of the Eindhoven WWTP upgrade

    This paper illustrates how a dynamic model can be used to evaluate a plant upgrade on the basis of post-upgrade performance data. The case study is that of the Eindhoven wastewater treatment plant upgrade completed in 2006. As a first step, the design process based on a static model was thoroughly analyzed and the choices regarding variability and uncertainty (i.e. safety factors) were made ...

  • Design of fine-bubble aeration systems for municipal WWTPs with high sea salt concentrations

    The impact of sea salt on the aeration coefficient kLa of fine-bubble aeration systems was investigated in clean water and in a model substance for simulating activated sludge. The investigations were carried out at laboratory and pilot scale. Sea salt was dosed in the form of artificial seawater, real seawater or simplified, by adding NaCl. The investigated media showed an increase of ...

  • Challenges in Designing an Odor Control System to Make a 32 mgd WWTP Odor Free

    INTRODUCTIONCity of Bakersfield located in Kern County, CA, is carrying out a major expansion to one of its wastewater treatment plants called Plant 3. Currently, Plant 3 treats about 15 mgd of wastewater flow with a design capacity of 16 mgd, on an Annual Average Dry Weather Flow (AADWF) basis. The current expansion will take the existing plant to an AADWF capacity of 32 mgd. As part of the ...

  • Model-based control structure design of a full-scale WWTP under the retrofitting process

    The anoxic–oxic (A/O) municipal wastewater treatment plant (WWTP) of Manresa (Catalonia, Spain) was studied for a possible conversion to an anaerobic/anoxic/oxic (A2/O) configuration to promote enhanced biological phosphorus removal. The control structure had to be redesigned to satisfy the new necessity to control phosphorus concentration, besides ammonium and nitrate concentrations ...

  • WWTP Industrial Coating Sector

    The pre-treatment operations prior to coating are the core of the fi nishing process of metal and plastic products: The end quality of any type of coating can precisely depend on a proper pre-treatment. Two types of pre-treatment are carried out in the metal coating processes: Chemical and mechanical. For the second type, dry technologies are used, such as shot blasting, sand blasting and so on, ...

  • Model Testing Optimizes and Verifies Design of a 200-MGD Trench Wet Well for the Sugar Creek WWTP

    Charlotte-Mecklenburg Utilities (CMUD) and CDM are currently involved in the design of several treatment plant upgrades at the Sugar Creek wastewater treatment plant (WWTP) in Charlotte, North Carolina. Implementation of this project, which includes a 200-million-gallonper- day (mgd) screenings and influent pump station with dual self-cleaning trench-type wet wells, will provide CMUD with the ...

  • Design, Construction, Installation, and Operation of a Compact Bio-Oxidation System to Manage Odors at the City of Wilsonville WWTP

    ABSTRACTThe 5 mgd Wilsonville WWTP was experiencing odor complaints from the adjacent residential neighborhood. An existing in-ground, bark and wood-chip biofilter was not performing well. In December 2004, the City of Wilsonville contacted BioReaction Industries (BRI) requesting the design of a bio-oxidation system with guaranteed performance criteria. The project required an understanding of ...
