Treatment of Electroplating Wastes

چکیده
~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 technical information and assistance.

Use of Electroplating Industry Sludge as a Construction Material
Every industrial unit generates wastes along with the processed goods. These wastes actually represent loss of the valuable material and energy from the production processes and investment in the pollution control. Usual approach followed by the industries, to cope with the problem of wastes and pollution, is use of waste treatment systems as end-of-pipe remedies. The remedies adopted often res...
متن کاملRecovery of Metals from Electroplating Wastes
Disposal of metal finishing wastes is one of the most critical industrial waste problems in the United States today. Recent legislation greatly restricts the discharge of most heavy metals to watercourses and future discharge regulations may further restrict their release to the environment. Furthermore, interest in developing possible methods for reclaiming metals from plating waste streams is...

Waste water, spent solvents, and spent process solutions are the major waste streams generated in large volumes daily in electroplating plants. These waste streams must be sigdicantly reduced to prevent pollution and reduce end-of-pipe treatment cost. In this endeavor, a computer-aided tool, WMEP-ADVISOR, is developed for source reduction by resorting to artificial intelligence techniques. This...

During the last years our research group has been studying the use of industrial vegetable wastes as grape stalks and exhausted coffee to remove metals ions such as Ni(II), Cu(II), Pb(II), Zn(II), Cd(II) or Cr(VI) and Cr(III) in aqueous solution from the point of view to use these wastes as biosorbents in a low cost alternative to activated carbon for wastewater treatment. The optimal experimen...
