Reuse of treated effluent is a highly valued water source in Palestine, however with limited success due to public health concerns. This paper assesses the potential pathogens in raw, treated and reclaimed wastewater at Albireh urban wastewater treatment facility, and provides scientific knowledge to update the Palestinian reuse guidelines. Laboratory analyses of collected samples over a period...

In this paper, the utilisation of zeolites synthesised from fly ash (FA) and related co-disposal filtrates as low-cost adsorbent material were investigated. When raw FA and co-disposal filtrates were subjected to alkaline hydrothermal zeolite synthesis, the zeolites faujasite, sodalite and zeolite A were formed. The synthesised zeolites were explored to establish its ability to remove lead and ...

A study of pollutant flows was carried out at a wastewater treatment plant in Nancy, France, which used activated-sludge treatment. To carry out observation of hourly flow variation, a sampling strategy needs to be defined. A comparison between two methods of sampling was conducted: dip samples every 2 h over a period of 24 h and one 24-h composite sample were taken from raw and treated wastewa...

Background: Aminoglycoside antibiotics are widely used in medical centers, particularly to treat infections. The resistance developed against these agents is a huge concern in health care. A number of researchers have reported that hospital and municipal wastewaters are among the most important dissemination sources of these agent into the environment. Some, however, do not agree with this opin...

Laboratory strains of Escherichia coli containing plasmid pBR325 (or pBR322) were coincubated with a mobilizer strain of E. coli (containing the conjugative plasmid R100-1) and a recipient strain of bacteria. Bacterial strains isolated from raw wastewater or a plasmid-free E. coli laboratory strain served as recipients. Transfer of the pBR plasmid into the recipient strain occurred during a 25-...

To assess the type and load of helminths in wastewater and the quality of treatment, we examined the raw and treated wastewater of 8 wastewater treatment plants (WTP) in Tehran and 2 in Isfahan for the presence of helminth eggs during 2002-2003. Wastewater samples obtained from both inlet and effluent of each treatment plant were examined on several occasions using the modified Bailenger method...

wastewater contains a variety of chemical substances owing to the different sources that contribute to affluent into sewage treatment plants. raw and wastewater samples were obtained from the surface of the water bodies at depths of 50 and 100 metres but at different locations in each sampling site. the water samples were subjected to extraction of polychlorinated biphenyls (pcbs) using quecher...

aims: textile wastewaters are the most important health and environmental problems in kashan. this research was aimed to compare the poly aluminum chloride and chlorinated cuprous efficiency for removal of chemical oxygen demand (cod) and color from kashan textile industries company wastewater. materials & methods: this experimental bench scale study in a batch system was conducted on 20 compos...

Recent molecular characterizations of Cryptosporidium parasites make it possible to differentiate the human-pathogenic Cryptosporidium parasites from those that do not infect humans and to track the source of Cryptosporidium oocyst contamination in the environment. In this study, we used a small-subunit rRNA-based PCR-restriction fragment length polymorphism (RFLP) technique to detect and chara...
