Data on this paper show the concentrations of COD, BOD5, TSS, K+, Ca2+, Na+, Cl-, [Formula: see text], [Formula: see text], Mn2+, Fe2+, Mg2+, Zn2+, Ni, Pb, Cu and Cd in the influent and effluent of wastewater, and also the nematode eggs, total and fecal coliform in effluents from wastewater treatment plant of Rasht, Guilan Province, in Iran. Measurements of pollutants in influent and effluent w...

A Sequencing Batch Reactor (SBR) is a wastewater process that occurs in a unique basin working with a predefined cycle. The reactor is monitored by the pH, Oxidation Reduction Potential, Dissolved Oxygen and Temperature sensors. This work proposes a qualitative representation of process variables based on episodes for ORP and pH signals to determine the complete denitrification and nitrificatio...

A wide range of synthetic chemicals and their metabolites present in the environment can antagonise the receptor activity of androgen hormones present in wildlife and humans. With increasing global production of new synthetic chemicals, little is known about their environmental fate, health consequences and end-points. This study was conducted to identify and characterise chemicals with anti-an...

This paper presents the results of a global sensitivity analysis (GSA) of a phenomenological model that generates dynamic wastewater treatment plant (WWTP) influent disturbance scenarios. This influent model is part of the Benchmark Simulation Model (BSM) family and creates realistic dry/wet weather files describing diurnal, weekend and seasonal variations through the combination of different g...

Escherichia coli is used as an indicator microorganism in public health. The conventional way to detect E. coli requires several days to produce a result, because it requires incubation of cells. Therefore a rapid and sensitive detection method is needed. T4e-/GFP phage, characterized by suppression of lysozyme and fusion of GFP (green fluorescent protein) to its SOC (small outer capsid) protei...

Article Type: Full Length Research Article The aim of this investigation was to confirm a trickling filter filled with gravel as an alternative biological process over conventional high cost treatment process with regard to nutrient reduction from brewery wastewater. Steady state evaluation of the trickling filter aerobic and anaerobic biofilm system for nutrient removal was made. The results o...

Continuous flow experiments were conducted using sand-packed columns to investigate the relative significance of bacterial growth, metal precipitation, and anaerobic gas formation on biologically induced clogging of soils. Natural leachate from a local municipal landfill, amended with acetic acid, was fed to two sand-packed columns operated in upflow mode. Degradation of the influent acetic aci...

Executive Summary A series of experiments were performed in a small but full-scale CDS device to determine its ability to remove free oil and grease from polluted waters using sorbents. Nine experiments were performed using five different sorbents. One control experiment was performed without a sorbent. The sorbents were allowed to float on the surface of the separation chamber of the CDS devic...

The use of ethanol as an automotive fuel oxygenate represents potential economic and air-quality benefits. However, little is known about how ethanol may affect the natural attenuation of petroleum product releases. Chemostat experiments were conducted with four pure cultures (representing archetypes of the known aerobic toluene degradation pathways) to determine how ethanol affects benzene, to...
