At this stage, used water that contain microscopic particles including bacteria are filtered out.
At this stage, undesirable contaminants from filtered water on earlier stage are now removed. The water at this stage is called high grade water.
The water is passed through ultraviolet light to ensure that there is no remaining organisms. Chemicals are also added into the water to restore its pH balance. The water that gone through all the processes above is called Newater and is ready to be used!
