Group Description
The group of three are currently year three
students from Singapore Polytechnic studying the diploma in Environmental
Management and Water Technology. Our
course made us realise the water issues happening around the world and
therefore we hope to provide a solution to these problems. Participating in
this competition will allow us to gain a deeper understanding of water issues
and solutions as well as meeting and exchanges ideas with people with the same
interest. Throughout the competition we will
also be taking advice from our lecturer, Dr. Handojo.
Project
Description
Rainwater
harvesting for potable use is gaining more attention due to water scarcity.
Rainwater appears to be clean, no smell and taste. However rainwater from
rooftop contains various toxic dissolved metal ions. The conventional treatment
using sand filtration system cannot remove metal ions. This project will
propose an alternative solution which incorporates coffee residue sand mixed
filtration. The products come with bottle and simple column and it will show
some lab analysis showing the capability in removing copper ions. It shows a
potential to offer clean water suitable for emergency situation or countries like
ours that has minimum water resources.
