  • Upgrading of Kish Island Markazi wastewater treatment plant by MBBR

    The potential of a moving bed biofilm reactor (MBBR) in full scale has been investigated as an alternative for upgrading of the Kish Island Markazi wastewater treatment plant. In this regard, the activated sludge process (ASP) upgraded to an MBBR process and different operating parameters results in this change compared with ASP. Results show that with increasing the average flow influent from ...

  • Aeration upgrade

    The community of Moscow is located in the northeast corner of Pennsylvania, approximately 10 miles southeast of Scranton. The current WWTP consists of an activated sludge system with three oxidation ditches in parallel operation. The total volume of all three ditches is 0.372 million gal per day (mgd), while the average size of each ditch is 180 ft by 24 ft by 6 ft deep. Previously, two of the ...

  • Upgrading an existing wastewater treatment plant based on an upflow anaerobic packed-bed reactor

    Upgrading a wastewater treatment plant (WWTP) may be necessary to meet the existing effluent quality and/or to meet the stricter future effluent quality requirements and/or to increase its capacity because of population growth or sewerage expansion to serve more areas. Inability to meet the existing effluent quality may result from lack of proper plant operation and maintenance, inadequate plant ...

  • Fluidized Fixed-Film Systems For Cost Effective Upgrade Of Existing Wastewater Treatment Plants

    As capacity demands increase and effluent quality regulations become increasingly stringent, a rising number of wastewater treatment plants across North America are in need of process upgrades. Nutrient removal requirements and high quality effluent standards for wastewater reuse have become more prevalent in recent years to safeguardaquatic habitat and conserve water resources. Upgrading large ...


  • Probabilistic modelling and evaluation of wastewater treatment plant upgrades in a water quality based evaluation context

    Process choice and dimensioning of wastewater treatment plants (WWTPs) is difficult while ensuring regulatory standards are met and cost-efficiency is maintained. This step only accounts for a small fraction of the upfront costs, but can lead to substantial savings. This paper illustrates the results of a systematic methodology to evaluate system upgrade options by means of dynamic modelling. In ...

  • Impact of the As Samra wastewater treatment plant upgrade on the water quality (COD, electrical conductivity, TP, TN) of the Zarqa River

    The impact of the As Samra wastewater treatment plant upgrade on the quality of the Zarqa River (ZR) water was investigated. Time series data that extend from October 2005 until December 2009 obtained by a state-of-the-art telemetric monitoring system were analyzed at two monitoring stations located 4 to 5 km downstream of the As Samra effluent confluence with the Zarqa River and about 25 km ...

  • Wastewater Treatment Plant Town of Guilderland, NY

    The Town of Guilderland has been dependably served by a 1.5 meter BDP belt press since its installation in 1983. In 2004, the Town decided that an upgrade was necessary, and chose BDP due to their service and equipment reliability. The Town of Guilderland installed a 2.0 meter 3DPTM, and immediately experienced dryer cakes with higher throughput resulting in lower disposal costs. The 3DPTM was ...
