| Abstract | This study was conducted at Chromalloy (Thailand) Ltd, which is a jet engine component repair factory. This factory has already obtained TSO 9002 and IS014001 certification. Tn view of the environmental management performance of the factory, this study was conducted using the Eco-mapping. It was found that there were two major problems which affected the workers had the negative thinking. One problem was Air pollution and another one was Noise pollution in the work place. The produced airborne particulate matter satisfies the Thailand standard. Noise level in the building is not higher than standard. However, the factory should create a strict rule for all the workers who work in dangerous areas, such as: Blending, Vibro room and LPT (Low Pressure Turbine) blade area. After conducting a pollution prevention in the chemical room, This study shows that a spray system which can reduce water used could be employed. 90% of rinsing water can be saved. Energy used could be reduced by 3 kWh per tank if the labourers open the tank heater less than 1 hour in the current operation. The simple in-plant modifications such as: closing of tap water after using, repair of leaky valves and connections and avoiding plastic bags and rubber ring from entering the wastewater stream could be adopt. The wastewater generated from rinsing operation, fluorescent penetrant solution and chemical use in the factory. Currently the factory generates 17 m3 /day from domestic wastewater and 15 m 3 /day from industrial wastewater. Domestic wastewater treatment plant and industrial wastewater treatment plant are over designed by 2 times and 10 times, respectively. The removal efficiencies of industrial sedimentation tank were 38% of SS and 62% of Ni, indicating very low removal efficiency. Life cycle analysis presented that the acidification and nutrient enrichment of after modification have lower environmental impact values than before modification. Therefore after the modification, the factory can be environmentally more friendly than before. |
