가압형 미세여과장치의 전과정평가를 이용한 수질개선효과 분석

This study is aim to improve the water quality using pressurized microfiltration device which is changed from square to circular shape and to analyze the environmental effects of the production and operation steps. This study analyzed the environmental impacts that occurred from production to purification in pressurized filtration equipment using Life Cycle Impact Assessment method. The target of the analysis is a pressurized circular filtration device(K-WHEEL F1200), which is an improvement device of the conventional square filtration device. As a result of the Life Cycle Assessment, the eutrophication index was analyzed 5.43E+03 kg PO₄^3- in circular type and 7.92E+03 kg PO₄^3- in square type. Also, improvement effect of water quality in circular filtration device was 3% better than the square filtration device and comparing the eutrophication removal amount of raw water and filtration devices, Electricity(0.034 kW) was used less when removing 1kg of eutrophication in circular type. In the future, in order to cope with climate change and to secure and manage stable water resources, more researches and developments for additive microfiltration equipment may be done.
