What Is Wastewater Treatment?

Each and every day, most people worldwide create wastewater. Whether cooking or bathing, washing clothes or using the lavatory, people are constantly creating wastewater with little consideration of where it goes - and how exactly it is returned to rivers and seas, often cleaner than it was coming in. Modern wastewater treatment is a much needed spot of good news in the environment. What most ...

Determinants of wastewater treatment expenditure of Austrian communities

Wastewater treatment services are bound to rather strict environmental regulations. However, as the broad range of wastewater expenditure of communities shows, there is room for discretionary policies of communities. The current paper explores wastewater treatment expenditure of Austrian communities by employing a cross-section econometric model. To a significant extent, demographic, geographic ...

Economic feasibility study for new technological alternatives in wastewater treatment processes: a review

The concept of sustainability involves the integration of economic, environmental, and social aspects and this also applies in the field of wastewater treatment. Economic feasibility studies are a key tool for selecting the most appropriate option from a set of technological proposals. Moreover, these studies are needed to assess the viability of transferring new technologies from pilot-scale to ...

From TSS to MBTS and beyond – a Personal View of Biological Wastewater Treatment Process Population Dynamics

ABSTRACT The development of the tools needed to study the population dynamics of biological wastewater treatment processes is traced from its beginnings in the early 1900’s to today’s use of molecular biology tools (MBTs). Examples of the benefits of population dynamics research in improving the performance and aiding the design and operation of biological wastewater treatment processes are ...

Software Developed for “Sustainable Treatment and Reuse of Municipal Wastewater` by Menahem Libhaber and Alvaro Orozco-Jaramillo

In most developing countries many people are lacking access to water and sanitation services. Collection and conveyance of wastewater out of urban neighbourhoods is not yet a service provided to all the population and adequate treatment is provided only to a small portion of the collected wastewater, in most cases covering less than 10% of the municipal wastewater generated. In slums and ...

Immobilization of horseradish peroxidase on silane-modified ceramics and their properties: potential for oily wastewater treatment

Horseradish peroxidase (HRP) is proved being effective in eliminating oil from aqueous solutions, but the elimination is expensive because free HRP can not be reused. In present work, HRP was successfully immobilized on cordierite porous ceramics support with a novel method of N-β-aminoethyl-γ-aminopropyl-trimethoxysilane modification and glutaraldehyde activation. Under the optimized immobilized ...

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 ...

A guideline for simulation studies of wastewater treatment plants

Abstract: A guideline for simulation studies of wastewater treatment plants is proposed. The aim of the HSG-guideline is to define a reference quality level that helps to make the results of simulation studies comprehensible and comparable and therefore increases the quality and reliability of mathematical modelling in wastewater treatment. The paper gives a summary of the HSG-guideline, written ...
