background: desalination plants have an important role in providing community drinking water. the increasing trend of water consumption and decrease of natural resources of fresh water make this role even more important. the aim of this study was to evaluate the quality of inlet and outlet water of desalination plants by reverse osmosis (ro) process in qeshm, iran and also to compare the qualit...

A freestanding microchannel, with integrated temperature sensors, has been developed for highpressure . flow studies. These microchannels are approximately 20pm x 2pm x 4400pm, and are suspended above 80 pm deep cavities, bulk micromachined using BrF3 dry etch. The calibration of the lightly boron-doped thermistor-type sensors shows that the resistance sensitivity of these integrated sensors is...

Urban drainage networks (UDN) carry urban wastewater to wastewater treatment plants (WWTP) in order to regenerate it before releasing it to the environment. Combined UDN (CUDN) carry both rain and wastewater together, which can overload the UDN and produce combined sewer overflows (CSO) that pollute the environment. Management of CUDN is receiving increasing attention from both researchers and ...

the zarivar lake a freshwater lake in west of kurdistan province is home for large number of native plant and animal species therefore water quality and health of the lake are vital for conservation of these species. the present study aimed at evaluation of the zarivar lake using nsf- wqi as an indicator of water quality. wqi is a suitable tool to examine and classify spatial and temporal varia...

Laboratory scale studies have repeatedly reported high P-retention in slag, a by-product of the steel manufacturing industry. Thus, it has emerged as a potential material to increase P-removal from constructed wetlands (CWs). However, several limitations were highlighted by field experiments, including the high pH of treated water and clogging. We hypothesized that the addition of sedimentary r...
