Electrodialysis (ED) was used to purify ionic liquids systems. It was expected that impurity ions could be separated from the ionic liquid system. Competitive transport behavior was extensively investigated between ionic liquids and impurity ions. [BMIM][CH3COO] and NaCl were used as a model ionic l

A system coupling photocatalytic oxidation of titanium dioxide particles separated by non-woven membrane for the degradation of 4-chlorophenol in an aqueous solution was studied. Non-woven membranes with three different pore sizes were applied to compare their specific flux and permeate turbidity. T

Performance and fouling characteristics of two pilot-scale polyvinylidene fluoride hollow fiber microfiltration membranes for drinking water treatment were studied under the same flux and physical cleaning conditions. It is expected that this paper can provide insights into the functions of operatio

While removal efficiency of most components in water by RO membranes is very satisfactory, the removal of some trace elements such as boron by RO membranes, especially those with long service life, is relatively low. The interplay between pH and ionic strength is believed to be the key to understand

Coagulation experiments at pH values ranging from 3 to 7 were conducted on raw water samples from four Australian reservoirs—Hope Valley, Myponga, Moorabool and Mt Zero—to assess the removal of natural organic matter (NOM) with alum. The aim was to characterise the NOM in these water sources that is

Poor water governance regimes and the imbalance caused by the increasing demand for water and diminishing supply of water has resulted in severe water scarcity. Consequently, water management authorities across the world face the challenge to ensure that quantity, quality, distribution, and allocati

A low-temperature phase-change desalination process configuration is presented in this study. This configuration enables saline water to be evaporated at near-ambient temperatures under near-vacuum level pressures created by the barometric head without any mechanical energy input. Thermodynamic adva

Drinking water treated with chlorine or chlorine dioxide contains a mixture of different chlorine species. Their identification, especially at low concentrations, is still problematic because of the number of compounds produced, especially when mixtures of chlorine and chlorine dioxide are used. Thi

The removal of arsenic by a commercial nanofiltration membrane was evaluated with respect to the performance and mechanism. The important membrane properties governing the separation of arsenic, such as molecular weight cut-off (MWCO), electrokinetic charge and individual salts rejection characteris

Biological nutrient removal and the fate of two estrogenic compounds, bisphenol A (BPA) and 2,4-dicholorophenol (2,4-DCP) were studied using a sequencing anoxic/anaerobic-aerobic membrane bioreactor (SAM) which was fed with synthetic water and operated at SRT of 60 days. Total nitrogen (TN), total p
