Singapore Junior Water Prize (SJWP) 2019

Ever heard of the Singapore Junior Water Prize? This local competition held annually in Singapore gathers creative young minds to come up with innovative water solutions, raise awareness and interest in water and environmental issues. The winning team of the national competition stands a chance to vie for the international Stockholm Junior Water Prize in Sweden – and represent Singapore on this prestigious platform!

Since its inception in 2008, the competition is in its 12th year run which has seen Singapore bag two victories at the Sweden competition in 2012 and 2018. This year, the national competition has received over 30 team entries and is proud to have Wang Haiyi – the winner of SJWP from National Junior College (NJC), to represent Singapore in Sweden this coming August.

“I feel honoured that I am able to represent Singapore to present my work. Looking back, it was a journey filled with uncertainties and challenges and I am truly grateful for constant help and invaluable advice from my mentor Dr Ren Yi from IMRE, A*STAR and my teacher advisor Dr Adrian Loh from NJC.”

Haiyi came up with a simple, yet novel idea to improve the regeneration process of absorbents in wastewater treatment. There has been intensive research on developing more efficient absorbents, but an apparent lack in reusing these absorbents for a more feasible and sustainable approach.  

“Sadly, there hasn't been much focus on reusing the exhausted adsorbent. This does not solve the problem at all as the pollutants are merely changed from liquid to solid phase. Therefore, I decided to embark on the journey of developing effective ways to reuse it.”

When asked how Dr Ren Yi, A*STAR’s Institute of Materials Research and Engineering (Haiyi’s mentor) felt about her achievements:

“With little reference from literature, working on new regeneration processes for emerging adsorbent technology is challenging. Haiyi has planned it well. On one hand, she explored variables that could affect the novel electrochemical regeneration, and on the other hand, she studied and optimised the application of conventional thermal process for regeneration as a backup plan…she has overcome many difficulties in the project and her hard work led to the positive data in the development of the proposed technology. I am very proud of her achievement.”

The national competition also saw other interesting and notable ideas presented:

One team from ITE College East, noticed how most people have the wrong perception about the amount of ice cubes necessary to turn a beverage icy-cold. Their project titled ‘How Cold is Enough? Reduce Waste, Save Water, Energy and Money’ looks into how ice cubes often go to waste due to non-consumption and tries to determine the minimum amount of ice cubes needed to achieve acceptable coldness levels – which is usually lesser than perceived.

The Stockholm Junior Water Prize 2019 will be taking place in Sweden this coming August, which will be graced by Her Royal Highness Crown Princess Victoria of Sweden. Here’s wishing Haiyi all the best and we look forward to her competing meaningfully at an international level!
