Is NEWater energy efficient?
Desalination is an energy-intensive water source. Singapore currently uses reverse osmosis for its desalination, which uses about 3.5kWh/m3 of energy to make seawater drinkable. This process produces pure drinking water by pushing seawater through membranes to remove dissolved salts and minerals.
Is NEWater safe to drink?
Watch video below to learn more about the story behind this high-grade reclaimed water. NEWater is high-grade reclaimed water produced from treated used water that is further purified using advanced membrane technologies and ultra-violet disinfection, making it ultra-clean and safe to drink.
Why is NEWater expensive to produce?
Rainwater is collected through a comprehensive network of drains, canals and rivers, and channelled to reservoirs before it is treated to become drinking water. Desalination is the most energy-intensive of our four taps. This makes desalinated water the most costly to produce.
Is NEWater potable water?
The water is potable quality and is added to drinking water supply reservoirs where it is withdrawn and treated again in conventional water treatment plants before being distributed to consumers. Currently, however, most of the NEWater is used by industries requiring high purity non-potable production water.
What are the disadvantages of 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.
What are the disadvantages of desalination?
Desalination is not a perfected technology, and desalinated water can be harmful to human health as well. By-products of the chemicals used in desalination can get through into the “pure” water and endanger the people who drink it. Desalinated water can also be acidic to both pipes and digestive systems.
Why do Singaporeans drink pee?
“Basically, you drink the water, you go to the toilet, you pee and we collect it back and clean it,” he said. Today NEWwater makes up 30% of Singapore’s water, almost all of it used for industrial purposes. That’s simply a version of what happens naturally, water experts say.
What does NEWater stand for?
NEWater refers to the high-grade reclaimed water that has been purified with advanced membrane and ultraviolet technologies. Having passed more than 150,000 scientific tests, and satisfying the World Health Organisation’s requirements for safe drinking water, NEWater is said to be “ultra-clean and safe to drink”.
How is NEWater treated?
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.
How is NEWater sustainable?
NEWater, Singapore’s success story and a pillar of water sustainability, is a high-grade reclaimed water produced from treated used water that is further purified using advanced membrane technologies and ultra-violet disinfection, hence making it ultra-clean and safe to drink.
What are the advantages and disadvantages of desalination?
Advantages & Disadvantages of Desalination Plants
- Advantage: Provides Accessible Drinking Water.
- Disadvantage: High Costs to Build and Operate.
- Advantage: Quality and Habitat Protection.
- Disadvantage: Environmental Impact.
What are the advantages and disadvantages of NEWater?
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. In this long time it is yet to be 100 percent and probably wont be for a while.
What are the benefits of Using NEWater in water fabs?
For the water fabs using NEWater, fewer treatment steps were required to achieve UPW quality than were required with PUB potable water., This resulted in savings of up to 20% of water fab operators’ chemical costs. 8
Which is the best use of NEWater water?
Non-Potable Use. As it is ultra-clean, NEWater is used mainly for industrial and air-con cooling purposes at wafer fabrication plants, industrial estates and commercial buildings. The biggest users of NEWater are wafer fabrication plants, which require water quality that is even more stringent than water for drinking.
How does the NEWater water plant in Singapore work?
NEWater. The NEWater process recycles our treated used water into ultra-clean, high-grade reclaimed water, cushioning our water supply against dry weather and moving Singapore towards water sustainability. Today, there are five NEWater plants supplying up to 40% of Singapore’s current water needs.
