Waste Reduction in the Metal Finishing Industry
نویسنده
چکیده
The metal fmishing industry uses over 40 production processes to produce a wide range of metal products. Waste streams generated include wastewater, waste oils, spent solvents, and spent process solutions. Current1,v a wide variety of techniques which minimize waste are available. Cost-effective methods to reduce electroplating wastewater contamination include water conserv&ion and drag-out reduction, recovery and management. Ways to cost-effectively reduce the generation of spent metal-working fluids include establishing a fluid management program and installing a fluid recovery system. However, before any techniques are selected, a waste reduction survey should f m t be conducted.

متن کاملA Practical Tool for Source Reduction in Electroplating Plants
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...
متن کاملImpact of Construction Waste Disposal Charging Scheme on work practices at construction sites in Hong Kong.
Waste management in the building industry in Hong Kong has become an important environmental issue. Particularly, an increasing amount of construction and demolition (C&D) waste is being disposed at landfill sites. In order to reduce waste generation and encourage reuse and recycling, the Hong Kong Government has implemented the Construction Waste Disposal Charging Scheme (CWDCS) to levy charge...
متن کاملMeasures against water pollution in industries which perform metal finishing.
Effective legislation is the main driving force in controlling pollution and, indirectly in economizing in the use of water in industry. The control is exercised by municipal authorities over the discharge of waste water to public sewers or of river agencies that determine the quality of discharges to rivers. Important factors in the reduction of pollution in the metal finishing industries are ...
