... m3/d from MSF and 0.38 million m3/d from RO plants. Based on these figures, the daily chemical discharge amounts to 2,708 kg chlorine, 36 kg copper and 9,478 kg antiscalants, when effluent concentrations of 0.25 ppm, 0.015 ppm and 2 ppm are assumed, respectively. The sensitivity of the Red Se ...
Desalination 152 (2002)

The effect of pH, biosolid dosage, initial copper concentration, and contact time on copper removal from aqueous solutions using biosolids (waste sludge cake) was investigated through batch experiments. The copper removal increased by tim ...

... interaction between the sepiolite surface and Cu(II) ions was concluded to be a physical process. Desalination 238 (2009) 257–270 Adsorption of copper (II) ions onto sepiolite and electrokinetic properties Mehmet Doğan*, Aydın Türkyilmaz, Mahir Alkan, Özkan Dem¥rbaş Department of Chemistry ...
Desalination 238 (2009)

... of metal oxide. However, the relative contribution of two removal mechanisms has not reported. In this study, the removal characteristics of copper were investigated in terms of sorption kinetics and sorption isotherms. As initial pH of solution increased, the sorption capacity of slag ...

... removal of heavy metals from aqueous wastes is among the most important issues for many industrialized countries. Removal of lead (II) and copper (II) from aqueous solutions were studied using pomegranate peel (raw), activated carbon prepared from pomegranate peel (AC1) and activated carbo ...
Desalination 223 (2008)

The ability of natural zeolite (clinoptilolite) and exfoliated vermiculite to remove copper from aqueous solutions was studied in fixed bed column and batch reactors. The effect of agitation speed (0, 100, 200, 400 rpm), temperature (25 ...
Desalination 215 (2007)

... Copper rejections of a nanofiltration (NF) and a reverse osmosis (RO) membrane are investigated with coppersulfate and copper-nitrate solutions as test wastewaters. The copper content of the solutions represents the typical copper ion concentration of process waters from ...
Desalination 240 (2009)

II) ions were studied. The most conductive exchangers were chosen. The adsorption data showed a high selectivity of the zirconium phosphate towards copper ions in a concentration range from 0 to 0.5 mmol. Both exchangers were tested in ion-exchange-assisted electrodialysis of a 10!2 M solution ...
Desalination 162 (2004)

... of particular importance. In the present study, a synthetic ultrafine zeolite was initially applied as sorbent (in suspension) for the removal of copper and zinc cations, and also chromium(VI) oxyanions — the latter less effectively. The removal of cations by zeolite particles depends mainly o ...
Desalination 162 (2004)

The process, called electrodeposition, was used for recovery of metals from aqueous solutions. The aqueous solutions of the sulfate forms of copper and cobalt metals were used as the catholyte solution and 0.1 M NaNO3 was used as an anolyte solution. The effect of current density, meta ...
