Basal aquifer water is saline groundwater that often needs to be dewatered prior to mining. The oil sands industry is seeking cost-effective methods to treat basal aquifer water in order to allow its recycle to the bitumen extraction process. A hybrid desalination system consisting of advanced elect

Brine management is a major bottleneck for coal seam gas (CSG) production in Australia. This study investigated the concentration of CSG reverse osmosis (RO) brine using a pilot membrane distillation (MD). The system was equipped with a novel spiral-wound air gap membrane distillation (AGMD) module.

The aim of this study was to assess the formation and the behavior of halogenated byproducts (regulated THMs and HAAs, as well as nitrogenous, brominated and iodinated DBPs including the emerging iodo-THMs) along the treatment train of full-scale desalination plants. One thermal multi-stage flash dis

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

This work presents the results of the techno-economic analysis of a proposed 100 m3 day−1 desalination plant based on existing plate and frame MD technology coupled with a static solar collector field as main heat supply. The experimental results of one commercial and two pre-commercial MD modules ch

In this work, novel monovalent selective cation exchange membranes (CEMs) with different mixtures of polyvinylidene fluoride (PVDF) and sulfonated PVDF (S-PVDF) were synthesized. The selected composite membranes were modified by surface polymerization of polyaniline (PANi) to improve their monovalent

A new hybrid cation exchanger poly-o-toluidine–thorium(IV)molybdophosphate (POT-TMP) has been synthesized using sol–gel method by the incorporation of inorganic precipitates of thorium(IV)molybdophosphate into the matrices of organic poly-o-toluidine. The product formation was optimized by varying t

Polysuccinimide (PSI) of various molecular weights (MW) was synthesized from aspartic acid. The PSIs were hydrolyzed with NaOH to obtain sodium polyaspartates. Partial hydrolysis of a PSI gave the copolymer poly(SI-cosodium aspartate). PSIs were treated with one equivalent of cyclic amines: pyrrolid
