Personal Reflection (NEwater visit)

I learnt that the membrane used to filter new water is very fine. I learnt how the UV light works. I learnt that singapore faced problems especially water shortages and we have to conserve water.
The two concepts are how water is filtered and what is NEwater is used for. The interesting thing that I learnt today is that the UV light is actually 800˚c hot and the bulb is encased is quartz to reduce the temperature. I can help by not leaving the tap running when brushing teeth.
