Application study of red tide monitoring to desalination plants using chollian (COMS)

Abstract

AbstractChollian (Communication, Ocean, and Meteorological Satellite (COMS)) is a geostationary satellite developed jointly by the Ministry of Land, Infrastructure, and Transport (MOLIT), the Ministry of Education (MOE), the Korea Communications Commission (KCC), and the Korea Meteorological Administration (KMA). Chollian serves not only as communications and weather satellites but also as a marine observation satellite capable of detecting ocean surface 8 times a day with Geostationary Ocean Color Imager (GOCI). Most of the recent desalination plants use Seawater Reverse Osmosis (SWRO) process, and chlorine cannot be used because the RO membrane in the main SWRO process is made of polyamide (PA). Therefore, it is very vulnerable to biofouling due to the influence of red algae and marine micro-organisms contained in seawater. This study aimed to evaluate the applicability of the “red tide monitoring system” capable of detecting and preventing the influx of red algae adversely affecting operation and maint...
