... achieved at higher pH as the molar ratio of [COOH] to [Sr] increased from 0 to 27. Desalination 147 (2002) 289–294 Effect of precipitation and complexation on nanofiltration of strontium-containing nuclear wastewater Eui-Deog Hwanga, Kwang-Won Leea, Kwang-Ho Choob, Sang-June Choib*, Seung-Hyun Kimc ...
Desalination 147 (2002)

... (PVA) and polyethyleneimine (PEI) was evaluated by determining metal, color, turbidity and chemical oxygen demand (COD) removal. In general, the complexation/ultrafiltration process was efficient in the removal of those parameters from wastewater, leading to a better effluent quality when compared t ...
Desalination 144 (2002)

Membrane permeation combined with complexation was tested for radioactive wastes processing purpose. The ceramic membranes MEMBRALOX® and CéRAM INSIDE® were used. To enhance the UF
Desalination 144 (2002)

A process for purifying wastewaters containing heavy and toxic metals such as cadmium and zinc by the complexation–filtration process was studied. From previous research, diethylaminoethyl cellulose (DEAE23) was selected as the complexing agent. Th ...
Desalination 198 (2006)

An efficiency of humic acids (HA) removal from aqueous solutions by complexation-ultrafiltration (COUF) process was investigated. The rejection of commercial HA (Aldrich) in the presence of two weakly basic, cationic wate ...

... ionic species in solution on the permeate flux through the ultrafilter and the rejection of the metal species by it. Keywords: Ultrafiltration; Complexation; Polyethersulfone membrane; Metal ions; Poly(vinyl alcohol) 0011-9164/07/$– See front matter © 2007 Elsevier B.V. All rights reserve ...
Desalination 217 (2007)

Characteristic features of ultrafiltration water treatment and water treatment using ultrafiltration in combination with complexation for water polluted with U(VI) were investigated. Polyethylenimine (PEI) was used as the complexing agent. The relationship of U(VI) removal as ...
Desalination 162 (2004)

... polymer in combination with ultrafiltration (UF) was used in a hybrid approach for selective removal and recovery of copper from water. In the complexation–UF process the cationic forms of heavy metals were first complexed by a macro ligand in order to increase their molecular weight to having ...
Desalination 162 (2004)

The membrane method combined with complexation was applied for hazardous wastes containing radioactive substance processing. Such complexing agents like soluble chelating polymers an ...
