Sustainability-week 2 reflection

After today’s discussion, we finally altered and came up with our research topic which is to evaluate the different techniques use by various nations to ensure water sustainability in the country using the following factors- cost effectiveness, long term sustainability, eco-friendliness.

For example, in Canada water is commonly purified using the Nano-Filtration and Reverse Osmosis method. This technique provides filtration at the molecular level which allows hardness, iron, tannins and other contaminants to be filtered out of the water which conventional filtration cannot remove. This technology provides a very pure product without the need for more cumbersome and invasive methods such as chlorination, ion exchange and sedimentation. While in Japan, similar to Sinapore, desalination is carried out to ensure a safe, reliable and affordable supply of water for their citizens.

Through our findings, I realized that various nations actually learn and adapt from one another water management method in order to attain long-term sustainability of water resource.
