China has the world's largest and still growing wastewater sector and water market, thus its future development will have profound influence on the world. The high-speed development of China's wastewater sector over the past 40 years has forged its global leading treatment capacity and innovation ability. However, many problems were left behind, including …
Moreover, the median and mean of TN concentration reached 10.2 mg/L and 10.0 mg/L in 2018, respectively. The TN concentration of 94.6% WWTP effluent in 2018, accounting for 57.24 × 10 9 m 3, was below 15 mg/L, satisfying the class 1-A standard. The TP concentration in the effluents of WWTPs also improved during the past decade.

In any case additional purification technology is needed to further improve the water quality. For example, the final effluent of the WWTP is further treated till irrigation water or a high quality process water. Or even drinking water? Reusing water has the potential for cost reduction in water supply and to reduce pressure on water resources.

Oxygen slave controllers, in a cascade setup. Investigations were performed for an Anaerobic-Anoxic-Oxic municipal WWTP case study. The benefits of the proposed control structures are revealed by assessing the Pumping Energy, Aeration Energy and Effluent Quality performance indices. INTRODUCTION* Waste Water Treatment Plant (WWTP)
In recent years, there has been a notable increase in research efforts pertaining to water treatment, with particular emphasis on investigating the role of DO (Åmand et al., 2013).The published papers were reviewed to (1) identify the reasons for high energy consumption in biological wastewater treatment, (2) compare the performance of wastewater treatment …
Différencier les deux grands types de disques de meuleuses qui sont les disques à tronçonner (disques diamants) et les disques pour les travaux en surface (disques à lamelles, disques abrasifs, disques avec brosse). Sélectionner le bon disque de meuleuse selon les travaux à réaliser et notamment la matière à découper ou surfacer.
This research investigates the cost-effectiveness of four sludge treatment scenarios for centralized (C) and decentralized (D) wastewater treatment plants (WWTP) using life cycle cost assessment ...
Les déchiqueteuses à double arbre sont plus puissantes et dynamiques que les déchiqueteuses ordinaires et peuvent couper plusieurs types de matériaux, y compris le carton de toute épaisseur ou taille. La majorité des déchiqueteurs de carton à double arbre sont équipés d'un seul moteur.
The effluents from wastewater treatment plants (WWTPs) can be an important contamination source for receiving waters. In this work, a comprehensive study on the impact of a WWTP from Madrid on the aquatic environment has been performed, including a wide number of pharmaceuticals and pesticides, among them those included in the …
To go further, statistical relationships between WWTP inlet flow rate and rainfall were studied and taken into account for each WWTP in order to calculate contextualized SARS-CoV-2 loads. This metric presented improved correlation strengths with COVID-19 prevalence for WWTP particularly submitted and sensitive to rain. Such findings …

1. Introduction. With the increasing development of urbanization, water pollution in towns have become more serious (Yu et al., 2019).To effectively reduce the pollutant release and lower water pollution, much stricter regulations and discharge standards have been adopted in China, which has furtherly promoted the wastewater treatment infrastructure …
Wastewater treatment plants (WWTPs) are implicated as hotspots for the dissemination of antibacterial resistance into the environment. However, the in situ processes governing removal, persistence ...
Although studies on microplastics in wastewater treatment plant (WWTP) treated effluent have recently been published, no standard method for sampling, identification and quantification of microplastics has been established, which complicates the comparison of results across various studies. This paper presents an attempt to optimize the Wet ...
In the past years, strict standards and laws have been considered in relation to the effluent of wastewater treatment plants (WWTPs) with the aim of protecting the environment and …

However, it was detected in other studies in UK at 359.3 ng/L in WWTP influents and 52.7 ng/L for WWTP effluents (Evans et al., 2015), and from 15.0 to 99.9 ng/L in WWTP influents (Baker and Kasprzyk-Hordern, 2013). To the best of our knowledge, this was the first time that norephedrine was found in WWTP samples in Portugal.
Wastewater Treatment Plants (WWTP) commonly involve a series of biological transformation processes that are usually very complex in terms of biochemical and biokinetics understanding [], and therefore, also in terms of everything related to its modelling, optimization, and automatic control [2, 3].The type of waste treated is mostly …
