3 learning points
1. I learnt of the technology they use to filter the dirt.
2. I learnt that Singapore's Newater was drank by the PM during its releae to the public.
3. I learnt that Newaters filtering system consisted of three parts- the filter, the partially permeable membrane and the ultraviolet canister.
2 things to be improved on
1. the introduction video
2. the time constraints
1 important thing I learnt
Newater used had to pump the water back into the reservoirs to take back the nuetrients it lost through the filtering.
