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....

BACKGROUND In recent years, decreasing annual rainfalls in some countries and population growth have led to a shortage of freshwater resources. Thus, recycled wastewaters has been suggested for agricultural activities. Contamination of wastewaters with pathogens is a major concern for the use of these waters. This study aimed to (i) investigate the occurrence of helminth eggs and protozoan (oo)...

Abstract In this paper, we propose to apply the linear mixed effects model (LMEM) for first time in discipline evaluate wastewater treatment plant (WWTP) data. Because most widely used statistical analyses cannot handle data dependency, as well fixed and random factors, a new approach was essential. We LMEM method analyze three groups of 19 pharmaceuticals personal care products (PPCPs) from Ca...

The occurrence of Clostridium difficile in nine wastewater treatment plants in the Ticino Canton (southern Switzerland) was investigated. The samples were collected from raw sewage influents and from treated effluents. Forty-seven out of 55 characterized C. difficile strains belonged to 13 different reference PCR ribotypes (009, 010, 014, 015, 039, 052, 053, 066, 070, 078, 101, 106, and 117), w...

OBJECTIVE Environmental estrogens at an elevated concentration are known to produce adverse effects on human and animal life. However, the majority of researches have been focused on industrial discharges, while the impact of livestock wastes as a source of endocrine disrupters in aquatic environments has been rarely elucidated. In order to investigate the contribution of environmental estrogen...

Background: The reuse of treated municipal wastewater is an important source of water for different ,purposes. This study evaluated the efficiency of the electrocoagulation process in removing turbidity,a total suspended solids (TSS), chemical oxygen demand (COD), nitrate, and phosphate from wastewater at the treatment facility in Karaj, Iran. Methods: This experimental study was performed at ...
