the influence of leachate from open solid waste dumping near salhad stream (abbottabad, pakistan) was investigated to quantify the variations of water quality during august 2007 to april 2008. samples were collected from five different sites located along the salhad stream. two sites were located before the mixing of solid waste leachate with the surface water. one sampling site was of leach...

Introduction: Corrosion and scaling of water in distribution systems in spite of imposing economic and aesthetic problems can lead to adverse effects on consumers' health. The present study was conducted to evaluate the corrosion and scaling of water distribution system of Sarableh city (Ilam, Iran) during summer and winter seasons in 2014. Materials and methods: Totally, 60 samples of wate...

Coalbed methane (CBM) or coalbed natural gas (CBNG) is an unconventional natural gas resource with large reserves in the United States (US) and worldwide. Production is limited by challenges in the management of large volumes of produced water. Due to salinity of CBM produced water, it is commonly reinjected into the subsurface for disposal. Utilization of this nontraditional water source is hi...

There is an increasing need for the desalination of high concentration brine (>TDS 35,000 ppm) efficiently and economically, either for the treatment of produced water from shale gas/oil development, or minimizing the environmental impact of brine from existing desalination plants. Yet, reverse osmosis (RO), which is the most widely used for desalination currently, is not practical for brine de...

today many countries have water shortage problems, so most of them compel to resort to desalination processes. this paper describes the effect of indirect contact freezing by external cooling for desalination of seawater and brackish water. although various types of processes are introduced for desalination and such processes as reverse osmosis (ro) and multi-effect distillation (med) are used ...

This study compares the performance of simulated shallow ponds vegetated with Lemna minor L. under controlled and semi-natural conditions for the treatment of simulated wastewater containing textile dyes. The objectives were to assess the water quality outflow parameters, the potential of L. minor concerning the removal of chemical oxygen demand (COD) and four azo dyes (Acid blue 113, reactive ...

Concentrations and temporal changes in concentrations of nitrate and total dissolved solids (TDS) in groundwater of the Bunker Hill, Lytle, Rialto, and Colton groundwater subbasins of the Upper Santa Ana Valley Groundwater Basin were evaluated to identify trends and factors that may be affecting trends. One hundred, thirty-one public-supply wells were selected for analysis based on the availabi...

Shahrekord groundwater is the main source of water for drinking, and the agricultural and industrial activities of its inhabitants. Water quality measures of scaling and corrosion can deteriorate steel-based systems used for storage or supplying water for drinking and to industry and irrigation. The main aim of this study was to assess the spatial variability and mapping of scaling and corro...
