Introduction of NEWater

NEWater is reclaimed water which has gone through treatment in NEWater Pants that consists of four processes: Microfiltration, Reverse Osmosis, water Conditioning and Ultraviolet Disinfection. After these four processes, the pure water can be used for both protable and non-portable purposes.

The below are the basic steps for the four processes with brief explanation. We will be researching more on the individual process to find out more about the Physics principle behind it.
In the first step of NEWater, water will go through microfiltration. It consists of tiny fibers which traps the solid (mostly bacteria and harmful micro-organisms) in the tubes. Besides, it can ensure a good stream of steady flowing water to prevent blockage and clogging up.

Later in the process of reverse osmosis, water will be applied pressure that would allow the water to flow from the concentrated side to the less concentrated side through a partially permeable membrane. In this process, viruses and dirty content like nitrate, chloride, sulphate etc will be removed.

For safety precaution, a back up process Ultraviolet rays is added in to wipe out harmful particles in one zap.

Lastly, the cleansed water is mixed with reservoir water to give it a “water taste” and is ready to be drunk.
