Researchers from the Department of Biotechnology, Graduate School, Universitas Padjadjaran —John Alezander Gobai— have published a comprehensive review titled “A Critical Review of Nanobubble Flotation for Seawater Treatment Process”. The study synthesizes current research on the application of nanobubble flotation—a process that leverages ultra-fine, gas-filled bubbles to separate pollutants—for enhancing the efficiency of seawater treatment. The review covers essential aspects such as generation methods, pollutant removal mechanisms, performance optimization, limitations, and real-world deployment challenges. By combining technical evaluation with process-level insights, the authors underscore this emerging technique’s potential to deliver cleaner seawater with lower energy input and reduced chemical use.

The review contributes significantly to advancing key Sustainable Development Goals (SDGs). It aligns with SDG 6 (Clean Water and Sanitation) by exploring an innovative, effective solution to enhance water purification in coastal areas. Through its focus on minimizing energy and chemical inputs, it supports SDG 12 (Responsible Consumption and Production) by promoting cleaner, greener treatment technologies. And by underscoring scalable, environmentally safer alternatives that could benefit underserved coastal communities, it helps drive progress toward SDG 14 (Life Below Water) by reducing marine pollution and improving ecosystem health.
