Personal Reflection (NEwater visit)

1. What are the 3 key takeaways from today’s visit?
The 3 key takeaways from today's visit are about the reservoirs in Singapore, the treatment process of the NEWater and the technology involved in the process.

2. Name 2 concepts that you have learnt today during the visit.
I have learnt about ultrafiltration and reverse osmosis.
Ultrafiltration uses a "case-like" thing to purify the water.
Reverse osmosis is like a thin string which has a lot of pores that only allow water molecules to pass through.

3. What is the 1 interesting thing that you have learnt today?
The interesting thing that I have learnt today is that if the pores in reverse osmosis is the size of a tennis ball, a water molecule will be like a ping pong ball. A mineral would be a soccer ball. A virus would be the size of a truck and a bacteria would be the size of the water plant.

4. What are the things that you can do to help with water conservation in Singapore?
I can help by carrying out the 3Rs. I can use the water after washing the rice to water the plants.
