Application of the hybrid complexation-ultrafiltration process for removal of metal ions from galvanic wastewater

Is biosorption suitable for decontamination of metal-bearing wastewaters? A critical review on the state-of-the-art of biosorption processes and future directions

“…This is due to the presence of a variety of metal ions along with counter anions, surfactants, brighteners and organic/ inorganic addition agents. The concentration of metal ions also varies and depends upon the type of chemical operations, size and shape of the surfaces, and on the washing system applied (Bodzek et al, 1999). For example, Agarwal et al (2006) reported that in chrome plating industries, the concentration of total chromium varied from 78 to 286 g/L in an electrolytic bath stream to 0.1e0.9 g/ L in a diluted rinse discharge stream.…”

“…A variety of stormwater BMPs have been developed in recent years. Among these technologies, biofiltration (also known as bioretention systems and rain gardens) operates by filtering diverted runoff through dense vegetation followed by vertical filtration through filter media (Bratieres et al, 2008;Read et al, 2008). The filter media usually consists of sand, bark or compost and a drainage layer.…”

Application of the hybrid complexation–ultrafiltration process for metal ion removal from aqueous solutions

“…The complexation-ultrafiltration process has been applied to treat various wastewaters [2,3,9,10], ground and underground waters [11,12], as well as the removal of radionuclides [13]. Trivunac and Stevanovic [14] tried to remove cadmium and zinc ions by using diethylaminoethyl cellulose as a complexing agent.…”

Industrial wastewater treatment by means of membrane techniques

“…Various polymers can be used as a complexing agent -poliethyleneimine, sodium polyacrylane. High efficiency of metal recovery, up to 92% was achieved 8 .…”
