background sewage sludge (biosolids) is a byproduct of wastewater treatment that accumulates in large quantities. effective stabilization and disinfection of sewage sludge prior to land application are necessary to not only protect human health, but also to induce the public its benefits and safety. currently, many wastewater treatment plants in iran dispose great amounts of untreated sewage sl...

Conventional wastewater treatment, primary and secondary treatment processes with simultaneous phosphorus precipitation, is the most common process combination used in Finnish wastewater treatment plants (WWTPs). It typically eliminates most of the organic load and phosphorus, as well as part of the enteric microorganisms present in raw wastewater. Municipal secondary effluents still contain so...

It is assumed that microbial communities involved in the biological treatment of different wastewaters having a different chemical composition harbor different microbial populations which are specifically adapted to the environmental stresses encountered in these systems. Yet, little is known about the composition of these microbial communities. Therefore, the aim of this study was to assess th...

Introduction There is a significant and inevitable fact in Turkey which is the “sludge problem” generated from the wastewater treatment plants. There are many sludge disposal techniques currently applied in Turkey such as incineration, landfilling, composting, etc.; but the disposal of sludge with those conventional methods is difficult and expensive, often requiring over 50 per cent of the ope...

This paper presents MoSS-CC (Model-based Simulation System for Cost Calculation in wastewater treatment plants), a software tool to optimise wastewater treatment plant design and operation by means of simulation and cost analysis. The scenario analysis procedure is encoded in the software as a VPL (Virtual Product Lifecycle). Roughly, the scenario consists of two phases: the design phase and th...

This paper reports on the design, implementation and real-time operation of advanced process control and monitoring techniques for wastewater treatment plants. The paper presents the development of a software platform and its implementation in a full-scale wastewater treatment plant. The software platform allows the real-time execution of advanced process control techniques as model predictive ...

Pharmaceuticals and other micropollutants have been detected in drinking water, groundwater, surface water, and soil around the world. Even in locations where wastewater treatment is required, they can be found in drinking water wells, municipal water supplies, and agricultural soils. It is clear conventional wastewater treatment technologies are not meeting the challenge of the mounting pressu...

The efficiency of the Wastewater Treatment Plant (WWTP) strongly depends on the inlet flow and the component concentrations of the wastewater. The forecasting of WWTP load gives promising opportunities to accomplish relevant operational actions. A predictive control strategy has been implemented. Taking advantage of the recognized properties of universal approximation of neural networks (NN), a...

Energy and water are inextricably linked, and together they are the two of the most valuable global resources. Internationally, the links between the energy, wastewater and water sectors are attracting increasing attention. In the wastewater sector, pressures including increasingly stringent environmental regulations and greater volumes of wastewater being produced and treated are a major chall...
