Advantages and Distadvantages of NEWater

This process is very expensive, including the cost of payment equipment and machinery. Economically, newborns have disadvantages and benefits. Newborns can help Singapore and help them rely on other countries. These countries include Malaysia with a contract with Singapore on imported drinking water. As NEWater dramatically reduced its trust, Singapore saved a lot of money. Malaysia will no longer be able to threaten Singapore due to increased taxes or costs of drinking water transport.

Freshwater is a process of treating wastewater into ultra clean and high quality regenerated water, accounting for 40% of Singapore's current water usage. Freshwater is mainly used for cooling purposes for industrial and air conditioning and is supplied through a dedicated piping network. During the drying period, fresh water is added to the PUB reservoir, mixed with raw water, processed in a water treatment plant, and then become drinking water. By 2060, New Water is expected to meet the water demand of 55% of the country in the future

A remarkable example of a combination of wastewater treatment and drinking water treatment is NEWater in Singapore. Freshwater is a technology to convert wastewater into drinking water in Singapore. More specifically, in addition to conventional water treatment processes, treated wastewater (sewage) is treated with bilayer membranes (by microfiltration and reverse osmosis) and ultraviolet technology. Water is drunk and consumed by humans, but it is mainly used in industries that need high purity water. The total capacity of these plants is about 75,700 cubic meters per day. Approximately 6% of this is indirect drinking, equivalent to approximately 1% of Singapore's 14 m 3 / s drinking water demand. The rest are used in wafer manufacturing plants and other non-alcoholic uses in industries such as Wood fab, Tampines, Pasir Ris, Ang Mo Kio and others.

Building the entire hydraulic power plant infrastructure and cost is a costly task. For example, in June 2010 SembCorp's new hydropower plant construction cost was $ 180 million. These costs will increase dramatically as more freshwater plants are needed to meet water demand. In the near future. Machinery and maintenance costs for these plants are also high (Vincent Wee, 2009). Secondly, the Singaporeans are accustomed to drinking directly from the faucet and believe that the new water dispenser is dirty and not suitable for drinking. They believe that neonates are not strong enough to remove toxic substances or chemicals that may be washed away at home or small business. At this time, this has been proved to be a major obstacle in the thinking of these people, and we can accept new technologies in Singapore (Singapore Press Holdings 2002). As explained in Chapter 2, NEWater's entire process is complex and goes through various stages before it is completed. Because of the complexity of these processes, it is impossible to deliver the product within the specified standard, even if human error or computer error occurs at any stage.
