Adsorption of Heavy Metal Ions from Electroplating
of carbon on the adsorption of metals was studied by add-ing 20 mL each of the electroplating wastewater to various amounts of the adsorbent (1.0 - 2.0 g) in different plastic bottles covered and agitated on a mechanical shaker. The equilibrium time and the pH were kept constant during this test. To determine the effect of pH on the adsorption of
completely recycle treated water to producing lines. In the case of electroplating wastewater treatment, it might be realized by chemical precipitation followed by other process such as biological treatment, reverse osmosis, ion exchange, adsorption, and electrodialysis (Bakkaloglu et al., 1998; Ahn et al., 1999; Ribeiro et al., 2000).

Treatment of an industrial wastewater. To validate the suitability of electrocoagulation for the treatment of industrial wastewater, an electrolysis was carried, using a wastewater sample, collected from an electroplating unit and the residual concentrations of Cu 2+, Zn 2+ and Cr(VI) together with COD were measured at different times of electrolysis.

used in the adsorption tests: First, synthetic solution (or synthetically prepared electroplating effluent) was prepared using a chromium (IV) atomic absorption standard solution (Aldrich, 1000 mg/L Cr in nitric acid) and softened tap water (free carbonates), Fe total = 1 mg/L and SO 4 –2 = 200 mg/L.

Adsorption chromium (VI) in electroplating wastewater
The chromium (VI) adsorption of electroplating wastewater could be decribed by Freundlich adsorption model. The kinetic of adsorption could be elucidated by pseudo-second order. The mechanism of the adsorption occurred in 2 steps.
The F-sand has shown improved adsorption performance and was used to adsorb chromium from electroplating wastewater. Since the hydrothermal treatment and the followed silica coating did not cause changes in the chemical properties of the sand as glass ingredient, the spent adsorbents containing homogeneously distributed chromium were successfully applied in preparing clear green glasses.
Advances in water treatment by adsorption technology
Since the introduction of adsorption in the 1940s, activated carbon has been the first choice for the treatment and recycling of municipal and industrial waste water to a potable water quality

- Can cationic polyacrylamide be used in oilfield wastewater treatment?
- Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.
