  • 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 ...

  • Wastewater characterisation and performance upgrading of a domestic wastewater treatment plant: the Erzincan case

    A detailed characterisation of the incoming wastewater and a performance evaluation were carried out for the domestic wastewater treatment plant of Erzincan City. Conventional characterisation results showed that Erzincan has a medium strength wastewater quality. Structural characterisation of the chemical oxygen demand (COD) indicated that the biodegradable fraction of the total COD was 64.7%. ...

The burgeoning tourist destination of Branson, MO lies in the bordering Stone County. Marionville has a population of roughly 2,140. The waste water treatment plant required a new Headworks system as part of a general ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Pendleton wastewater treatment plant biogas application - Case Study

    About the Project In 2011, the City began work on a cogeneration facility as part of the upgrades at the Waste Water Treatment Plant. The city was given us the ability to convert solids arriving at the Waste Water Treatment Plant into useful energy and high quality fertilizer. The system was designed to generate about 750,000 kWh per year, which translates into about $50,000 annually ...

  • Airlift bioreactors: Application to wastewater treatment

    After an introductory review, this paper presents a three-phase reactor fluid dynamic model that is used in the development of a generic process for upgrading existing wastewater treatment plants (WWT). The aim is to incorporate nitrification and de-nitrification without additional reactor volume. The core of the process consists of an attached growth airlift reactor (AGAR) in which a biomass ...

  • Scaling-up of a zero valent iron packed anaerobic reactor for textile dye wastewater treatment: a potential technology for on-site upgrading and rebuilding of traditional anaerobic wastewater treatment plant

    Anaerobic digestion (AD) is a cost-effective technology for the treatment of textile dye wastewater with clear environmental benefits. However, the need to improve process feasibility of high treatment efficiency as well as to shorten hydraulic retention time has raised interest on several intensification techniques. Zero valent iron (ZVI) packed anaerobic digesters have the potential to ...
