Seawater desalination is an increasingly common means to meet the demand for freshwater. Resulting wastewater discharges can, however, impact biota of the surrounding environment. Concern exists that interactive effects specific to the outputs of each desalination plant may result in unique impacts d

Produced water management is one of the key challenges faced by the oil and gas industry globally. Specifically, the gas industry in Qatar is challenged to minimize the produced/process water (PPW) volumes injected into disposal wells to ensure long term sustainability of the reservoirs. This researc

A protocol is proposed whereby waste fly ash and CO2 emissions from coal fired power plants are utilized in remediating brine waste. The solid residues generated may be used as mine backfill since they consist mainly of benign calcium carbonate. Following treatment with fly ash and CO2, over 99% removal

This article discusses the available alternatives for ocean concentrate disposal, site specific factors involved in the selection of the most viable alternative for a given project, and the environmental permitting requirements and studies associated with their implementation. The article focuses on

The forward osmosis (FO) process potentially can be used as an alternative to traditional brine treatment technologies due to its low energy requirement. In this study, the feasibility of concentration of brine by the FO process was investigated using a laboratory-scale unit. An FO membrane and the

Desalination of seawater accounts for a worldwide water production of 24.5 million m3 /day. A “hot spot” of intense desalination activity has always been the Arabian Gulf, but other regional centers of activity emerge and become more prominent, such as the Mediterranean Sea and the Red Sea, or the c

Southern Tunisian’s natural brines represent an important source of mineral salts with a high economic value. These salts are recoverable by simple solar evaporation. Indeed, during isothermal solar evaporation it is possible to recover mineral salts and to determine the precipitation sequences of t

Processes of desalination of seawater are intended to reduce the deficits in potable water both at present and in the future. Water desalination processes offer various environmental benefits (related to sanitation, water softening, quality of sewage effluents), but the process is also accompanied b

The separation performance of Na+ ions from NaCl solution has been investigated by electrodialysis at constant voltage mode of operation. TS-1-10 electrodialysis equipment (Tokuyama) modified with rotameters was employed in experimental studies. During an unsteady-state run of the ED system, both in
