This week, during CCA session, Cedar Environment Club invited Dr Adrian Yeo from Singapore Membrane Technology Centre to organise a hands-on workshop for all our members.
First, Dr Yeo did an introduction on membrane technology and how water could be filtered using hollow fibre membranes.
Then, the Sec 3 students who were taking part in the inter-school water filtering competition gave a presentation on their experience in water filtering as well as the conclusions that they had reached after trying out different glues and lengths of membranes.
After that, Dr Yeo's colleague brought the members some membranes, glue and transparent tubings. As soon as the glue dried, everyone queued up to test their membranes by trying to filter diluted Milo. Only about 2 or 3 out of 14 students managed to filter clean water out of the diluted Milo.
The Environment Club members definitely had a great time trying to make their own water filtering membranes!
Cedar Environment Club would like to thank Dr Yeo and his colleague sincerely for specially coming down to our school to give us this exclusive workshop.
