Is Singapore facing water shortage?
Water demand in Singapore is currently about 430 million gallons a day (mgd) that is enough to fill 782 Olympic-sized swimming pools, with homes consuming 45% and the non-domestic sector taking up the rest. … By then, NEWater and desalination will meet up to 85% of Singapore’s future water demand.
Why is desalination so expensive?
One common desalination method, reverse osmosis, is expensive because it requires a great deal of electricity to push water through a filter. It’s also costly to treat the water to kill microbes and to replace the filters. Researchers are hoping that improved membrane materials could make this process cheaper.
What is the difference between NEWater and desalinated water?
Desalinated water, which currently meets up to 30 per cent of water demand and will meet 30 per cent of future demand in 2060, is the most energy-intensive water source. NEWater, on the other hand, currently makes up 40 per cent of water demand, and meet up to 55 per cent of future demand in 2060.
Is NEWater only in Singapore?
The first NEWater plant was completed in May 2000. Singapore currently has four operational NEWater factories, at Bedok, Kranji, Ulu Pandan and Changi.
|Plant name||Sembcorp NEWater Plant|
|Date of commissioning||2010|
|Current capacity||50 million imperial gallons (230,000 m3)|
What are the disadvantages of using NEWater?
Although NEWater is very a very effective process, it has a couple of disadvantages. NEWater will not be able to produce enough potable water to be independent. It is now only able to produce 30 percent of Singapore’s demand. In the future, 2060, it is predicted to meet 55 percent of Singapore’s demand.
How is NEWater treated?
In 2003, high-grade reclaimed water, known as NEWater was introduced. NEWater is recycled from treated sewage (‘used water’) and produced using a rigorous 3-step purification process involving ultrafiltration/microfiltration, reverse osmosis (RO) and ultraviolet (UV) disinfection.
Is NEWater pure water?
Currently 98% water used in SSMC is Newater. The Newater supplied by Public Utility Board (PUB) is of high quality and cheaper compared to Domestic water and therfore suitable to produce Ultra Pure Water at manufacturing Plants.
