[1] Variability in sediment hydraulic properties associated with landscape depositional and erosional features can influence groundwater recharge processes by affecting soil-water storage and transmission. This study considers recharge to aquifers underlying river-incised glaciated terrain where the distribution of clay-rich till is largely intact in upland locations but has been removed by all...

desalination plants are potentially capable of having impacts on coastal marine environments due to the production of wastewater with high concentrations of salts (brine discharge) and some heavy metals. the aim of this study was to examine the concentration of accumulated metals (ni, cu, cd, fe, zn, pb) in the sediments near the brine discharge point in the chabahar bay. twenty one sediment sa...

Background Current recommendations are to calculate the adenoma detection rate (ADR) in screening colonoscopies only. The need to confine the measure to screening has not been established. Methods We retrospectively assessed our quality database for whether calculating ADR from screening, surveillance, and diagnostic colonoscopies (overall ADR) would alter conclusions about the performance of c...

Groundwater is a crucial resource for water supply and irrigation in many parts of the world, especially Middle East. The Eocene aquifer, located northern part West Bank, Palestine, threatened by unsustainable groundwater abstractions on-ground pollution. Analysis management this aquifer are challenging because limited data availability. This research contributes to long-term sustainability mod...

In the rapidly developing shale gas industry, managing produced water is a major challenge for maintaining the profitability of shale gas extraction while protecting public health and the environment. We review the current state of practice for produced water management across the United States and discuss the interrelated regulatory, infrastructure, and economic drivers for produced water reus...

Abstract In southern Belgium, 23% of abstracted groundwater volumes are from chalk aquifers, representing strategic resources for the region. Due to their specific nature, these aquifers often exhibit singular behaviour and require analysis. The quantitative evolution is analysed Mons Basin Hesbaye as a function past evolution, in short long term. Groundwater level time series decreases when ov...

This paper presents a hybrid solar desalination system consisting of a humidification dehumidification unit and single stage flashing evaporation unit. The hybrid solar desalination system was studied numerically. The heat and mass transfer and flow field is modeled theoretically in two-dimensional using finite difference scheme. For different operating and weather conditions the fresh water pr...

Brackish water (BW) desalination is a primary path to relieve the shortage of water. As one of the BW desalination methods, reverse osmosis (RO) technology has advantage for both technology and process procedure. The expounding of this research studied or reviewed recent years, reverse osmosis membrane, energy recovery, new energy and application technology in BW desalination of RO at home and ...

In this paper, a simulation model of a spray flash desalination system is proposed. In the spray flash desalination system, the freshwater is made from the evaporation-condensation process, i.e., evaporation of warm surface seawater in a flash chamber and condensation of the generated vapor by deep cool seawater. A simulation model of the spray flash desalination system is constructed by using ...

  All desalination methods which are currently used have limitations. A newly designed instrument by Zare A.M. was tested and compared with currently used method in Razi Vaccine and Serum Research Institute(RVSRI). Samples of anti snake venom for desalination was provided by department of anti-serum, RVSRI. Parameters included in this study were time and water consumption during desalination pr...
