Background: Pharmaceuticals used in human medical care are not completely eliminated in the human body and can enter the municipal sewage sludge system and leachate water from landfill both as the parent compound and as their biologically active metabolites. The selective serotonin reuptake inhibitors (SSRIs) have a large potential for unwanted effects on nontarget organisms in the environment....

High numbers (10 to 10 cells per g [dry weight]) of heterotrophic, gram-negative, rod-shaped, non-sporeforming, aerobic, thermophilic bacteria related to the genus Thermus were isolated from thermogenic composts at temperatures between 65 and 82&C. These bacteria were present in different types of wastes (garden and kitchen wastes and sewage sludge) and in all the industrial composting systems ...

This work evaluated the behaviour of a Pilot Plant to receive and pre-treat septage collected transported by trucks from decentralized sewage treatment systems greasy residues grease traps. was installed at Brasília Sul Sewage Treatment composed grid, equalization tank, rotating screen, crusher Central Unit for separating settleable solids (SetS) floating solids, mainly oils greases (O&G). ...

Background & Aims of the Study: The most important compounds in hospital wastewater are antibiotics, disinfectants, anesthetics, radioactive elements, static cytotoxic agents, other chemicals and hazardous materials that caused to be different domestic sewage. The purpose of this study was the evaluation of performance of extended aeration biological system in pollutants remova...

Due to urbanization and industrialization huge amount of wastewater is being generated, which causing water pollution. Nowadays pollution a serious problem. The present study has been carried out evaluate the efficiency waste treatment plants with Extended Aeration Sludge Process (EASP). This done by examining various physiochemical characteristics (BOD, COD, TSS & PO4), including compariso...

The main objective of this review is to evaluate the performance constructed wetlands (CWs) used reduce antibiotic-resistant genes (ARGs) during sewage treatment. To accomplish objective, statistical and correlation analyses were performed using published data determine influence operational design parameters on ARG reduction in CWs. effects parameters, such as different CW configurations, seas...

To improve nutrient removal, a full-scale hybrid constructed wetland (CW) consisting of pre-treatment units, vertical-baffled flow wetlands (VBFWs), and horizontal subsurface flow wetlands (HSFWs) was installed in August 2014 to treat sewage wastewater. Artificial aeration (AA) was applied continuously in the VBFW stage to improve the aerobic condition in the hybrid CW. Water samples were colle...

Enteroviruses survived for up to 38 days without diminishing in numbers in extended-aeration sludges maintained at 5 degrees C. In oxidation ditch sludges similarly maintained, enteroviruses survived for up to 17 days without diminishing in numbers. The pHs of the sludges in this study were well inside the pH 6 to 8 corridor in which destruction of enteroviruses by the detergents and ammonia pr...
