A conceptual model for decentralized municipal wastewater management
This paper proposes a conceptual model for selecting the centralization level for wastewater management in urban areas, which is associated with main sewage collectors and wastewater treatment facilities. The model is supported in the Analytical Hierarchy Process (AHP) and Cost-Benefit Analysis. Additionally, the model is based on the results of variables and indicators identified previously ...

Continuous treatment of flotation collector wastewater using a membrane bioreactor
Aniline aerofloat (DDA) is a widely used material in China and has become a main pollutant in floatation wastewater. In this study, a membrane reactor (MBR) was constructed to continuously treat simulated wastewater contaminated with DDA. The study investigated the hydraulic retention time (HRT) and the impact of influent DDA concentration on MBR performance, and analyzed intermediates from ...

Estimating the costs of collective treatment of wastewater: the case of Walloon Region (Belgium)
This paper contributes to a better understanding of costs for collective wastewater treatment in the Walloon Region (Belgium). Based on a large set of data, unit costs to population equivalents are modelled. Considering investment as well as exploitation costs, the model includes not only wastewater treatment plants but also collector and sewage networks in an integrated approach at the technical ...

Odour treatment in WWTPs . SIMTEJO case (Portugal) - Case Study
Controlling odor problems in sewage collectors and wastewater treatment plants is currently one of the main objectives to reduce and prevent potential problems related to worker safety and minimize the negative social perception that odor problems can generate. The main sources of odor generation in WWTPs are the phases in anaerobic conditions, where the lack of oxygen favors the development of ...

Oil skimming solution keeps national railway running year round
A North American railway that prides itself on environmental responsibility recently worked with an engineering firm to design a new wastewater treatment facility for one of its refueling stations in British Columbia. The design challenge required a careful balance of meeting the railway’s commitment to environmental sustainability, while still being able to operate in severe weather ...
