Environmental analysts are often tasked with the evaluation of illicit and prescription drugs in wastewater samples in an attempt to better understand the epidemiology of a populated area. Due to the challenging consistency of this matrix, clean-up is often vital in order to achieve accurate detection. In a recent paper authored by Richard Bade et al., published in Analytical and ...

In the present study, a pilot scale horizontal subsurface flow constructed wetland (CW) system planted with Phragmites karka; longitudinal profile was studied. The wetland was fed with tannery wastewater, pretreated in a two-stage anaerobic digester followed by a sequence batch reactor. Samples from each CW were taken and analyzed using standard methods. The removal efficiency of the CW ...

The primary effluent of a Municipal Wastewater Treatment Plant (MWWTP) is monitored to understand organic loading going to the next stage of treatment, the activated sludge process. This process removes organics via consumption by microorganisms living in the sludge. Knowing the composition of incoming primary effluent is important to prevent organic overloading and improve process optimization ...

In a case study located in suburban sectors of the metropolitan area of the Lerma Valley (Valle de Lerma), in the province of Salta (Argentina), 24 informal decentralized wastewater treatment systems (DWWTS) were evaluated. The analyzed systems had three general configurations: A, septic tank; B, septic tank combined with upflow anaerobic sludge blanket (UASB) reactor; C, septic tank combined ...

Fluidized granulation is one of the common methods used in wastewater treatment and resource recovery with harvesting millimeter-scale large particles. Presently, effective methods are lacking to measure the fluidized granules ranging from micro- to millimeter scales, with the consequence of ineffectively controlling and optimizing the granulation process. In this work, recovering struvite ...

Selective removal of Ca and recovery of Mg by precipitation from flue gas desulfurization (FGD) wastewater has been investigated. Thermodynamic analysis of four possible additives, Na2CO3, Na2C2O4, NaF and Na2SO4, indicated that both carbonate and oxalate could potentially provide effective separation of Ca via precipitation from Mg ...

In this paper, the measurement of biochemical oxygen demand (BOD) in a wastewater treatment process is analyzed and an intelligent integrated prediction method based on case-based reasoning (CBR) is proposed in order to overcome difficulties. Due to the fact that there are many factors that influence the accuracy of the prediction model, the radial basis function, which is a neural network ...

Flue gas desulfurization (FGD) wastewater treatment by conventional neutralization, chemical precipitation and coagulation process removes most suspended solids and heavy metals, and provides an effluent rich in calcium, alkalinity and chloride, which obstructs its reclamation and reuse but is in favor of phosphorus (P) precipitation. The goals of this study were to investigate feasibility of ...

Times are definitely changing. It used to be that wastewater from whatever source – domestic, agricultural, industrial – was something to collect and pipe away as quickly and efficiently as possible. There was more water coming out of the ground or falling from the sky, so why bother investing time and money cleaning water that had already been used? Now, thanks to issues like ...

Soluble microbial products, consisting of protein, carbohydrate and humics, are generally considered as the main membrane foulants during the performance of membrane bioreactors. Nitrate and nitrite have been proved to affect the determination of carbohydrate when anthrone-sulfuric acid photometric method is used. In this study, three chemical analytical methods based on photometric assay, ...

Microbes run the world. They are the governing agents behind the conversion of key elements into vital biological forms. They remove toxins from their environments, and protect us from disease-causing organisms. Microbes do not, however, go to battle alone. Microbe armies live in complex communities that follow intricate processes and interactions to ensure environmental stability. Until ...
