In-situ Control Technology and Application of Odor-producing Algae in Large Source Water Reservoirs

The algal-derived odor (2-Methylisoborneol, MIB) affects 40% of water source reservoirs in China and is challenging to remove using conventional treatment methods. It has become a key factor in limiting drinking water quality compliance. By overcoming the limitations of traditional morphological and molecular methods for algal species identification, a high-throughput single-cell-based gene fusion technology was developed for the precise identification of odor-producing algae. A “green” light modulation and algae control technology based on physical methods was proposed to reduce the production of drinking water odor at the source. These achievements provide systematic solutions for controlling drinking water odor in Beijing and Shanghai and have supported the optimized operation of 19 water source projects. Additionally, an industry guideline for odor control technology was compiled.
