Abstract
With the intensification of global water eutrophication, algae overgrowth-induced phenomena such as "algal blooms" and "red tides" have occurred frequently. These phenomena not only disrupt aquatic ecological balance but also threaten drinking water safety and human health. As a key link in water quality management, algae removal technology has become a research hotspot due to its requirements for efficiency, safety, and sustainability. This review summarizes the current research status of algae removal from the perspectives of physical, chemical, biological, and emerging technologies. It aims to provide theoretical references and practical basis for the eutrophication control of different water bodies (lakes, reservoirs, drinking water sources).
Keywords: Algae removal technology, water eutrophication, ecological impact, technical synergy, resource utilization
