Transcript of Kurnell Desalination Plant

Kurnell Desalination Plant Kurnell Desalination Plant The Kurnell desalination plant is located in southern Sydney, NSW Australia It is also the largest operating desalination plant in the country Sydney's people mainly rely on dams and rainwater for their drinking water. This amount of people grow roughly by 50,000 people per year. The always increasing requirement leads to new technologies being created, such as the desalination plant. After dam levels sank to 34% in February 2007, the decision was made to construct the desalination plant. This desalination plant supplies Sydney with 250 million litres of water daily, and 15% of Sydney's water need. It has technically paid for itself. The Kurnell desalination plant uses around 32 kilometres of deep sea tunnels that connect to the plant. These pipes direct sea water to the plant to be treated. The plant extracts drinking water from this seawater. They do this by using RO (reverse omnosis) technology. There are certain steps in the RO procedure that the seawater must undergo: The seawater is first transported through th pipes to the plant. There is goes through rounds of screening and pretreatment, which removes sand and other solids that could contaminate it. Then, using electrical energy, it is pumped through RO membranes. The fresh water is diffused through the membrane. The fresh water then goes through post-treatment, which is where the water is treated with fluoride and minerals so that the water meets health requirement standards. The now treated water is then transported into a storage tank, waiting to be transferred to the city's tunnels for use. For a while, environmentalists opposed the idea of the desalination plant, stating it would harm private property and the environment. But much care was taken to ensure that the plant would not harm marine life in any way. It's good to know that we're getting drinking water, but at the same time the wildlife isn't being harmed Remember: This ^^ Becomes This ^^ An eMineMineM production By Sonya 7B Bibliography:
