| Summary, etc. | This research case study is developed in view of setting up a demonstration project on °revealing the profitability of clean technology in small scale electroplating unit". It was conducted in a small scale electroplating shop, located in Bangkok. A set of simple in-plant control measures such as dragout recovery, spray rinsing technique, rinse water agitation were implemented. Quantitative data, obtained from the monitoring of wastewater before and after process modification, have indicated a substantial reduction both in quantity and strength of wastewater generated. Water consumption was reduced by approximately 35 % of total rinsing water, which is 18. 7% of total process water consumption. Average metal concentrations in wastewater was reduced 73% for Cr-, 71.3% for Ni- and 54.6% for Cu-plating rinse water. Segregation of different types of wastewater was performed. Experiments were conducted to investigate the feasibility of treatment and recovery of Cr and Ni using ion exchange, Cu using electrolysis. Results from ion exchange study showed that resin Purolite C-100 and A-100 can be used to remove effectively Ni2+ and Cu2+ ions from the wastewater when the feed concentration was under 500 mg/l, and chromate ions when feed concentrations do not exceed 1000 mg Cr6+ 11, respectively. The removal efficiency is dependent on feed flowrate applied. Ni and Cu can be recovered after additional purification of regenerant effluent. The N~Cr04 regenerant effluent from A-100 ion exchanger can be converted into H2Cr04 solution, using resin C-105. However it was not found economical. Electrolytic study revealed the possibility of using a simple electrolytic cell to bring a Cu metal concentration of 501.6 mg Cu2+ in wastewater down to 52.2 mg/I after 240 minutes, at 5 volt applied (3.06 mA/cm2). Stainless steel plate was not found to be appropriate anode for electrolysis of Ni-bearing solution. Recommendations were made for further study on ion exchange and electrolysis, as well as strategy on the pollution control in small scale electroplating industries in Bangkok. |
