Water Recycling from Electroplating Effluent Using Membranes

Abstract:

Article Preview

The membrane integrated process including nanofiltration (NF) and reverse osmosis (RO) had more advantages in recycling the electroplating effluent than conventional physical and chemical methods. Separation experiments with different kinds of membranes were carried out in pilot scale installation using industrial effluents for more effective desalination. The selective rejection of different ions in NF and RO process was investigated with the Donnan effects and solution-diffusion theory to check its consistence. Although NF membranes had a higher permeate flux and better ion selectivity even under a relatively low operating pressure, RO membranes prevailed in rejection of toxic heavy metal ions and COD and would approach a higher potential for producing feed water of industrial cooling system.
