Hello! I am Low Jeen Liang from Singapore. I’m 16 years old and a Secondary 4 student at Hwa Chong Institution. Personally, I am deeply passionate about science and technology. Being part of my school’s Science and Math Talent Programme, I have had numerous opportunities to obtain greater exposure to different scientific fields and engage in various scientific research projects. I am also a part of my school’s Waterpolo team, as I enjoy playing sports, especially swimming. Through this, I have come to better appreciate a strong sense of teamwork and resilience. Lastly, I treasure the time spent with my family, which consists of my parents and older siblings, who have provided me with constant guidance and support.Tell us what the water concern in your country is!
Singapore’s water concern is managing our limited water supply. Currently, Singapore depends on 4 main domains, which are local catchments, imported water, desalination and NeWater. Singapore prioritizes the development of more cost-effective and robust water treatment technologies to sustain its water supply.
Adsorption by activated carbon is conventionally used for wastewater treatment but is inefficient for pharmaceutical wastewater purification. This study investigates a novel, low-cost electrochemical enhancement of activated carbon fibre (ACF). With 1.0V applied, ACF’s effectiveness in removing acetone, a common pollutant in pharmaceutical waste, was increased by 107%. Over three cycles of adsorption and regeneration, the original effectiveness of unenhanced ACF plunged by 39.2%, while that of electrochemically enhanced ACF remained over 90%, demonstrating its increased reusability. A self-constructed prototype integrated electro-sorption and regeneration into one central chamber, allowing wastewater to be continuously purified as part of a cyclic process.
