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 …
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 …
Eco-efficiency evaluation using DEA. To evaluate the eco-efficiency of the WWTPs, we apply the DEA method. DEA is a non-parametric method that allows the construction of efficient production limits, applying linear programming to the inputs and outputs of evaluated units (WWTP for this case) (Cooper et al., 2007; Gómez et al., 2018; Molinos …
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 ...
Oxygen slave controllers, in a cascade setup. Investigations were performed for an Anaerobic-Anoxic-Oxic municipal WWTP case study.

Since WWTP are responsible for 1% of electricity consumption in European countries (Simon-Várhelyi et al. 2020) and 25–40% of operating costs in a WWTP are related to energy consumption (Panepinto et al. 2016 and references therein), it is crucial to evaluate the energy efficiency and to identify improvement measures. Regarding energy ...

Meuleuses fixe et portative Entreposer les meules sur des étagères ou des supports, dans un endroit tempéré et sec, à l'abri des chocs. Vérifier la date de fabrication inscrite sur l'étiquette de la meule et jeter les meules qui ont plus de deux ans, sauf les meules vitrifiées qui n'ont pas de date d'expiration.
Les meuleuses, ou les outils qui comportent une meule ou un disque abrasif, sont couramment utilisées sur de nombreux chantiers ainsi qu'au foyer. Pour les manipuler …
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.
Cet outil est également capable de polir les surfaces et de les rendre lisses. La meuleuse est l'outil idéal pour les travaux de rénovation et de construction. Découpage de la maçonnerie. Une meuleuse est un outil électrique portatif qui sert à découper, à affûter et à polir le métal, le béton, la pierre et d'autres matériaux.
Phosphorus (P) recovery is obligatory for all sewage sludges with more than 20 g P/kg dry matter (DM) from 2029 in Germany. Nine wastewater treatment plants (WWTPs) were chosen to investigate variations of phosphorus contents and other parameters in sewage sludge over the year. Monthly sewage sludge samples from each WWTP were analyzed …

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.
Mason et al. reported that a WWTP with a combined sewer system (i.e., including stormwater runoff), after a storm event, could increase fragmented particles in effluent. However, the researchers who paid attention to the effect of weather on MP abundance mostly focused on the environment sample base, ...
The number of MBR applications for wastewater treatment is growing rapidly: the total installed MBR treatment capacity globally was recently reported to have increased by …
Capacity of WWTP is the same as for a city with approximately 22,000 inhabitants. Technology used within the plant is divided into 2 sections. The first one is a mechanical part involving rotary sieve, accumulation tank and flotation unit. The main function is to remove bigger particles from wastewater, equalize water quality and remove part of ...

The evaluated municipal WWTP in Beijing is based on an anaerobic–anoxic–aerobic (A 2 /O) process which takes a market share of some 55% of China's WWTPs and is responsible for treating 61% of the total wastewater amount in China (Jin et al., 2014). Thus, the selected WWTP presents a generally applied process of most WWTPs in China.

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.
Previous studies (Mizuta and Shimada, 2010; Nowak et al., 2015; Longo et al., 2016) concluded WWTP EI was influenced by plant size. However, these studies focused primarily on evaluating energy consumed by conventional plants using CAS as the secondary treatment. Consequently, our findings contribute notably to understanding specific …

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.
