Presented in this paper is a graphical technique for freshwater and wastewater minimisation in completely batch operations. Water minimisation is achieved through the exploitation of inter- and intra-process water reuse and recycle opportunities. In the context of this paper, a completely batch operation is one in which water reuse or recycle can only be effected either at the start or the end ...

The main aim of this research is to determine optimal leaching conditions; Eh, pH and complexing agent concentrations, for recovery of Copper from hydroxide sludges such as those produced by electroplating shops, metal finishers, treatment of acid mine drainage, and industrial wastewater in general. This has been preceded by a theoretical approach and numerical and computer calculation. Pot...

Abstract Herein, a KFeS 2 whisker was formed in mass production at low temperature, with waste cold-rolling sludge as Fe source, which exhibited good performance the removal of Zn/Ni from real electroplating effluent. At laboratory scale, generated 80 °C by hydrothermal method, and grew radially extension reaction time. This method applied pilot where similar also produced residual brownish sup...

Cadmium is widely used in electroplating, batteries, plastics, and paints. a toxic element for humans, affecting mainly the kidneys skeleton. Adsorption an easy, effective, inexpensive method removing metal ions wastewater. In this research, we have synthesized calcium alginate-PVA beads as Cd (II) ion adsorbent. The adsorbent characterization was carried out using Fourier Transform Infrared Sp...

~sing of the environment, the electroplating industry is likely to be one of the industries to be affected by the introduction of the water pollution control legislation in Hong Kong. The effect may be even more pronounced for the operators of small and medium-sized electroplating factories since they are unlikely to have any expertise in pollution control and will therefore require outside tec...
