An algal bloom is a phenomenon in which phytoplankton including blue-green algae rapidly proliferate in summer, marked by high solar irradiation and water temperature. It has lately been raising concerns due increased frequency of occurrence resulting from abnormally high temperatures and decreases in precipitation caused by climate change. Certain species of blue-green algae produce substances that have an earthy or moldy taste and odor, and others that are toxic. Since these substances cannot be easily removed by a general water purification processes, additional treatment using advanced water purification facilities is essential.
