inFLOW: Hope for the Developing World

8 April 2013                 


Choon Siew Hui (left), final year student at Temasek Polytechnic’s School of Design, wants to make clean water accessible to people living in developing countries. Her inFLOW water filtration system is sure to bring us a step closer.

I was told about The Design Show 2013, held by Temasek Polytechnic’s School of Design. It was part of their Annual Graduation Show, where works of final year students would be on display for the public to view.

Most, if not all, the designs there were outstanding, but there was one in particular I thought I would share. It was a water filtration system, named inFLOW, which was conceptualized and prototyped by final year Product and Industrial Design student Choon Siew Hui.


A poster at Siew Hui’s booth showing the inFLOW prototype and detailing how it works.

Siew Hui’s prototype came in two parts, a backpack and a compartment. Her idea was to allow water to be filtered on the go, thus allowing people in third world countries with no access to safe, drinking water to treat their own water anywhere they are.

The compartment had to be filled with water and fitted into the backpack, which would allow water to flow through the first stage of the filter. Pressure can then be created using a pump, forcing the water through a membrane to make it safe for consumption. The backpack would then be removed from the compartment when the water level is low so it can be refilled and used again.

It’s refreshing to see Siew Hui, a teenager in a developed country, to be aware of the problems of access to clean water in other parts of the world. Her simple yet seemingly effective design has great potential. Perhaps certain parts of it still need more thought and refinement. For example, how would the people clean the inside of the water compartment with the unclean sediment? Still, I believe that if it goes to market, it will help millions of people get access to fresh, clean water.

Unfortunately, the exhibition has now ended, but I’m confident this wouldn’t be the last time we see Siew Hui’s brilliant invention.
