  • Biosolids- Considering the Types, Applications and Biosolids Drying Methods

    While some water treatment plants are meant to simply make the sludge safe enough to dispose of, most facilities continue to treat the sludge so that the material can be put to good use in their communities. Once sludge is treated and processed to meet EPA safety standards for productive use, the resulting nutrient-rich organic material is termed as biosolids. ...

  • The effect of BOD5 and flow-rate of activated sludge systems on investment and energy costs

    In this study of wastewater treatment, the effect of flow-rate, BOD5 and other design parameters (MLSS, mean cell-residence time, etc.) on aeration tank dimensions, investment amount and energy cost has been investigated. The relations among these parameters are represented with mathematical equations, which could be useful in new plant design and in the estimation of investment and energy ...

  • Study on Fully Coupled Activated Sludge Model No. 1 (FCASM1) for wastewater treatment biological processes

    Nowadays many types of model based on the Activated Sludge Models (ASMs) have been developed. Most of them supposed that all the substrate removal processes are independent. Based on the mechanism of the interaction among microorganisms and considering the interaction among the processes of organisms oxidation, nitrifying, denitrifying and biological phosphorus removal, Fully Coupled Activated ...

  • Actual scale experiment of selector application and the situation of bulking sludge problem in southern Thailand

    Activated Sludge Process (ASP) was applied to effluent from factories in southern Thailand. To increase their treatability using a limited land area for the treatment plant, the ASP was mainly designed for carbon removal. A survey of 17 wastewater treatment plants, in the concentrated latex rubber and seafood industries, was conducted. An actual scale experiment of selector application was ...

  • Behaviour of Selected Sex Hormones in Synthetic Influent of a Pilot-Scale Wastewater Treatment Plant.

     ABSTRACT The concentration of seven sex hormones, namely, estradiol (E2), estrone (E1), estriol (E3), ethynilestradiol (EE2), testosterone (TEST), androstenedione (AND) and progesterone (PROG), was studied over time in the liquid and solid phases of a synthetic wastewater to clarify the interactions between them and the non-soluble components. While the concentration of TEST, AND and ...

  • Design of a generalized predictive controller for a biological wastewater treatment plant

    This paper presents a generalized predictive control (GPC) technique to regulate the activated sludge process found in a bioreactor used in wastewater treatment. The control strategy can track dissolved oxygen setpoint changes quickly, adapting to the system uncertainties and disturbances. Tests occur on an Activated Sludge Model No. 1 benchmark of an activated sludge process. A T filter ...

  • Rural community sewerage case study

    Succeeded in "zero-emission" of sludge Previously, sludge was vacuumed out in this treatment plant without being dewatered; however, the cost for sludge treatment was huge. Thus, aiming at "zero-emission" of sludge, fermentation of the sludge was being considered. AMCON's offer for a solution They introduced Dell Compo, which can treat sludge ...

  • 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 ...
