Desalination

Data are presented from a series of laboratory experiments designed to evaluate separation performance and humic acid fouling for two RO membranes treating brackish water at temperatures of 15, 25, and 35°C. A model is proposed that considers changes only to solute and solvent properties. Model resu

Nowadays, more than 110 cities of China confront the serious problem of fresh water shortage, and more than 70% of the rivers and lakes are contaminated to some extent. About 38 million people are depending on brackish water for life. Desalination of seawater and brackish water is one of the ways to

Based on experimental data, a simulation and optimisation of the adsorption Á microfiltration (AMF) process for boron removal from reverse osmosis (RO) permeate was done. An impressively low flow rate of the dry boron adsorbent of about only 54.3 kg h(1 is needed in the adsorbent recirculation loop

In our present work, the preliminary electrodialytic desalination of wastewater containing 75 mg/L of boron and approximately 1.8 g/L TDS was investigated, as the first step in two-stage boron removal ED process. The wastewater in question originated from Tarnowskie Gry landfill chemicals storage.

The use of solar energy in thermal desalination processes is one of the most promising applications of the renewable energies. Solar desalination can either be direct; use solar energy to produce distillate directly in the solar collector, or indirect; combining conventional desalination techniques,

Water scarcity and pollution pose critical situation in all walks of life especially in the developing countries. Among the available purification technologies, solar desalination process proves to be a suitable solution for resolving this existing crisis. This renewable energy technology operates o

Desalination of brines produced from oil and gas fields is a potential resource for potable water in the southwestern U.S. and other semi-arid areas. Oilfield brines typically contain high concentrations of Na+ and Cl!, as well as other multivalent cations and anions that can reduce efficacy of reve

Demineralisation of tap water, produced from surface water (lake), by a membrane distillation process has been investigated. The temperature caused the decomposition of bicarbonates presented in the feeding water and the formation of alkaline scaling on the membrane surface. In the present work the

Following the creation of the first reverse osmosis (RO) membrane in the 1960s, the technique has been widely used for the purposes of both small scale and municipal seawater desalination. Forward osmosis (FO) is now also emerging as a possible contender, with the potential for much lower energy con

The objective of this work is to present experimental data that would show the effect of temperature, salinity, pressure and the presence of anti-scale additives on CO2 solubility in seawater. The paper examines the solubility of CO2 in real seawater and real seawater dosed with two different anti-s
