The presence of mutagenic and carcinogenic nitrosamines in groundwater is of great concern. In this study, eight nitrosamines including N-nitrosodimethylamine (NDMA), N-nitrosodiethylamine (NDEA), N-nitrosomethylethylamine (NMEA), N-nitrosopyrrolidine (NPYR), N-nitrosomorpholine (NMOR), N-nitrosopiperidine (NPIP), N-nitrosodi-n-propylamine (NDPA), and N-nitrosodi-n-butylamine (NDBA) and corresp...

Due to environmental burden and human health risks in developing countries, the treatment of decentralized domestic wastewater has been a matter of great concern in recent years. A novel pilot-scale three-stage anaerobic wool-felt filter reactor (AWFR) was designed to treat real decentralized domestic wastewater at seasonal temperature variations of 8 to 35 ◦C for 364 days. The results showed t...

We investigated the conventional characterisation and biological treatability of wastewaters of the “Izmit Industrial and Domestic Wastewater Treatment Plant”. Respirometric procedures were carried out for the experimental assessment of organic contents of wastewater. The mean value of total COD was 1201 mg·l-1 and varied within a wide range of 580 to 1822 mg·l-1 for the 14 different influents....

Novel advanced oxidation processes (AOPs) show great promise for application in many wastewater treatment areas. AOPs are an emerging technology that may be employed for specific goals in wastewater treatment. These AOPs utilize the very strong oxidizing power of hydroxyl radicals to oxidize organic compounds to the preferred end products of carbon dioxide and water. Advanced oxidation has been...

Introduction: The present study aimed to investigate the microbial quality of the produced vermicomposts and compare them with the existing standards. Materials and Methods: This experimental study was conducted as a pilot-scale one in the laboratory school. Some perishable domestic wastewater mixed in a reactor, including food waste, vegetables and fruits, cow manure and sludge from wastewate...

in order to investigate the effect of domestic wastewater and normal water (well water) on soil chemical properties and alfalfa yield, a research project was conducted for three years in chahartakhteh research station. the experiment was performed in randomized complete blocks design including four treatments in three replications. treatments were as follows: t1: irrigation with normal water at...

Direct Capillary Nanofiltration (Direct CNF) is a new technique used for surface water and wastewater treatment in one step without pre-treatment. The CNF membrane module combines the favourable cleaning properties of capillary ultrafiltration membranes with the favourable separation properties of nanofiltration membranes in terms of removal of DOC, colour, bacteria, viruses and pesticides. Dir...

Heavy metals pollution has become a more serious environmental problem in the last several decades as a result releasing toxic materials into the environment. Various techniques such as physical, chemical, biological, advanced oxidation and electrochemical processes were used for the treatment of domestic, industrial and agricultural effluents. The commonly used conventional biological treatmen...

Within the last decade, reproductive abnormalities have been discovered in wild amphibian populations of multiple species and in a variety of regions in North America. Predominantly, these field studies have focused on agricultural landscapes. In this study, we worked in suburban environments based on preliminary evidence showing that amphibian populations can display surprisingly high frequenc...
