A total of 394 bacterial isolates were isolated from Kasr AlAiny hospital wastewater effluent and river Nile water in Cairo (Egypt). Each 2 isolates from both sources were mixed in co-cultures and incubated (at room temperature) in sterilized Nile water for 48 hours under normal laboratory condition, taking into consideration the same gram staining and the different species. In addition, some i...

This paper presents a review of the current state of the art of real time control (RTC) of urban wastewater systems. Control options not only of the sewer system, but also of the wastewater treatment plant and of receiving water bodies are considered. One section of the paper provides concise definitions of terms frequently used in the literature. Recent developments in the field of RTC include...

with the development of the wastewater treatment plants and the increase in volume of treated wastewaters in our country, it is necessary to use treated wastewater wisely. landscape irrigation and agriculture applications considered as a significant scope for the treated wastewater. in this paper, the advantages and disadvantages of these applications are investigated and the importance of the ...

UNLABELLED The emission of particulate matter (PM10 and PM2.5) and ammonia (NH3) by aeration processes at wastewater treatment plants (WWTPs) with and without odor control units was examined. Local concentrations of PM2.5, PM10, and NH3 at the aeration basins were within urban ranges. Emission fluxes of NH3 and PM2.5 for a medium-sized WWTP were determined to be 136 g day(-1) and 43 g day(-1), ...

We evaluated the effluent quality of an urban wastewater treatment facility in South Africa and its impact on the receiving watershed for a period of 12 months. The prevalence and antimicrobial susceptibility of potential Listeria pathogens (L. ivanovii and L. innocua) and the physicochemical quality of the treated wastewater effluent was assessed, with a view to ascertain the potential health ...

a newly developed natural rubber deproteinization process produces deproteinized natural rubber (dpnr) wastewater as an intermediate product containing a high concentration of sodium dodecyl sulfate (sds) and rubber. in this study, a novel process to recover the residual rubber and energy as methane from dpnr wastewater was developed. as a pretreatment, sds and residual rubber in dpnr wastewate...

This study investigated the efficiency of electerocoagulation (EC) in removing color from synthetic and simulated textile wastewater. The study on decolorization of mixed dyes is a step toward an effective treatment of textile wastewater. Two representative reactive dye molecules were selected for the synthetic dye wastewater, a blue dye alone and mixed dye (black, blue, red, 1:1:1v/v). The EC ...

to evaluate the effect of slow release fertilizer and humic acid on quality of new guinea impatiens (impatiens hawkeri), an experiment established in complete random design with 15 treatments and three replications. treatments were slow release fertilizer (12-11-18-2.7mgo-8s) in five levels (0, 1.5, 3, 4.5 and 6 kg/m3) and humic acid in three levels (0, 2 and 4 kg/m3) that mixed with medium cul...
