Sydney Desalination Plant is located in the Kurnell Industrial Estate. it is a potable drinking water desalination plant which forms part of the water supply system of Greater Metropolitan Sydney. It supplies water to 17 suburbs, all around the east and inner west. It is not currently needed to treat water, and therefore the treatment facilities have been turned off. However when it is required for treatment, it uses a lot of energy, requiring energy a 67 turbine wind farm at Bungador. It currently supplies 15% of Sydney’s current water needs, and is part of an initiative by the NSW Government called Water4Life. The plant can produce 90 billion litres of drinking water per year.
The treatment process begins at the seawater intake area,

At this stage about 99% of the salt is removed from the water, as well as bacteria, viruses and other pathogens. There are 4500 pressure vessels in the plant, each with eight membranes, which are all laid end to end. At this stage anything larger than even a water molecule is …show more content…
These plants take water from nearby dams and treat it to drinking water quality, unlike the desalination plant which takes water from the ocean. The largest plant is at Prospect, which treats over 80% of Sydney’s drinking water. Refer to the diagram in Heading 2 for approximate locations.
Treatment methods at these nine plants vary slightly according to the water it treats and where it is going. However, all plants use filtration, disinfection and fluoridation methods.
In filtration, raw water passes through screens to remove material such as twigs, leaves and other particles. Chemicals are then added which clump together other particles, and the water is sent through another filter, usually lined with sand and anthracite (crushed coal).
Chlorine is added to the water to kill any remaining microorganisms. Ammonia may also be added if the water is required to travel long distances. Chlorine with ammonia forms chloramine, which lasts longer than chlorine
Sill P - Planning Prediction I predict that as the concentration of salt solution (molar dm-3) is increased, meaning that the water potential outside the carrot decreases, the water potential inside the carrot will decrease. As the water potential outside of the carrot cell is decreased, the water potential inside the carrot will increase, when the salt solution is more dilute. This change in water potential will occur because of a net movement of water molecules called osmosis. Osmosis is; The movement of water molecules from an area of high water potential to an area of low water potential, down the concentration gradient, across a partially permeable membrane. A partially permeable membrane, which is found in plant cells, such as the ones in a carrot, is a membrane that only allows certain molecules to pass through it, in this case, the membrane will allow water molecules to pass through it, but will not let the salt molecules pass through.
Warragamba Dam is vital for Sydney’s water supply as it supplies the highest quality of raw water available. The Sydney Catchment Authority ensures this and it is their goal to make sure that water quality continues to meet the Australian Drinking
Osmosis is a type of diffusion which is only applied on water and is a passive process which does not require an input of energy from the cell; this is because materials are moving with the concentration gradient. Osmosis is a process that occurs at a cellular level, which entails the spontaneous net movement of water through a selectively permeable membrane, from a region of high to low water concentration, in order to equalise the level of water in each region. This form of diffusion takes place when the molecules in a high concentration are too large to move through the membrane. The term semi-permeable or selectively permeable means that some substances can easily pass through the cell membrane, whereas others cannot. The significance of osmosis to cells is great, since it is the osmotic pressure that maintains the shape of an animal cell and provides support in the plant cells. Many factors affect the rate of osmosis including size of particles and temperature however in this particular experiment the factor investigated is the concentration of sodium chloride. Tubes of potatoes will be used to demonstrate the fact...
The existence of a waste water treatment plant will depend on local discharge requirements and the costs of waste water treatment. Relevant waste water treatment technologies involve neutralisation and anaerobic or aerobic processes.
The water that supplies Western Australia comes from a variety of sources, including surface water and groundwater. Recent technologies have emerged which allow WA to use water sources that were previously unusable, such as desalinated ocean water and recycled wastewater (Government of Western Australia, 2012). The scale for this report is the state of Western Australia. This scale will allow for analysis of more elements of water consumption in Perth and its surrounding areas, not just the city’s consumption of water, but consumption from other key industries that fuel the economy of Perth and WA, including mining and agriculture.
Osmosis in Carrots Background Osmosis is the diffusion of water from a dilute solution to a more concentrated solution through a partially permeable membrane, which allows the pass of water molecules but not solute molecules. [IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE]If a cell is placed in a less concentrated solution water enters because the less concentrated solution will have a high concentration of water than the inside of the cell. Once the cell takes in maximum water the cell becomes turgid. If the cell was to be placed in a high concentrated solution, water would leave the cell because the cell would contain a low concentrated solution. So in the low concentrated solution there will be a high concentration of water and in the high concentrated solution there will be a low concentration of water.

The water that they don't use and all of the salt goes back into the water. For example, ¨The second problem with desalination is discharging water. It is water that is released back into the ocean. Desalination typically uses two times more seawater than it produces in freshwater. To make 50 million gallons of fresh water, Carlsbad will need to draw in 100 million gallons of seawater. The leftover water will be returned to the ocean. However, it will not go back the way it came in: It will be much saltier. Normally, returned ocean water is twice as salty as when it was pulled in.¨ This shows that he water will not mix well with other water so the desalination should not be
The bacteria and wastewater is mixed in an aeration tank and therefore the contaminants are removed by action of sorption and series of breakdown by the bacteria.
Waste water treatment plants are essential to communities of all sizes and must work efficiently. Waste water treatment plant primary priority and responsibility is the treatment of incoming sewage water by the removal of biological and chemical wastes so it can be treated and recycled for future use. There are many government agencies and standards set forth to govern and observe the successful treatment of sewage such as: the Department of Environmental Quality, the National Pollutant Discharge Elimination System and the Clean Water Act of 1972. Compliance and constant monitoring of the treatment plant’s operations are important; as they protect the surrounding community. A spill or backflow of sewage due to a complete system malfunction could potentially be detrimental to the environment and local community. A precise system, of which must be compliant according to government standards, is critical to maintain low levels of wastes that are returned to neighboring water systems after treatment.
Before delving in to what is actually wrong with seawater desalination plants, it is important to establish that there are plenty of alternatives available. One of the best alternatives is to adopt more efficient practices, such as conservation of water, and recycling storm water and grey water (from washing machines and bathrooms...
For each water change, culture containers can be sterilized with bleach and water used should be filtered to 2µm and UV sterilized. Antibiotics (chloramphenicol, penicillin, sulphamethazine) could be added to cultures to minimize bacterial build-up between water changes. Addition of antibiotics to culture is not recommended for flow-through growth culture.
In addition to this, the ‘Sydney Catchment Authority’ was created in 1999. The Sydney Catchment Authority was created to manage and protect drinking water catchments. According to “Sydney’s Cryptic Water Crisis” the low water levels in reservoirs due to drought Sydney Water announced in 2007 it would build the Kurnell Desalination Plant, powered by wind energy, that would supply up to 15% of the drinking water supply to Sydney, the Illawarra and the Blue Mountains.” This is the largest water supply project for Sydney since 1960. Today, Sydney has 30 wastewater treatment plants and water recycling plants. These plants treat about 1.5 billion litres of wastewater today. This accounts for 12% of Sydney’s water needs. As for the droughts Sydney has experienced in this century and water levels that dropped about 32% in the Warragamba Dam, the NSW Government developed the Metropolitan Water Plan, which is the most recent response in water supply
PROPER IRRIGATIION CAN PREVENT SALT FROM BUILDING UP BECAUSE THE WATER CAN DRAIN THE SALTS AND SPREAD IT OUT SO THAT THE SALTS AREN’T CONCENTRATED IN ONE AREA!!!
Water plays such an important role in our daily lives. 70% of our body is composed of water. 70% of the earth surface is also made up of water, but out of the 70%, only 1/3 of water is consumable. In fact, this amount has been continuously to decrease as more and more industries began to pollute and damage the water. For example, many toxic chemicals may be released into the water thus making the water impure. Such pollutions and damages lead the water to be contaminated and inconsumable as it may cause severe diseases. Water purification can remove all the unnecessary bacteria and viruses from the water that is hazardous for our health. Water purification may also improve the flavor and appearance of water. It removes the unpleasant odor. Therefore, water purification became one of the most useful and popular process used by people all over the world today. It is by far the most recommended and safest water treatment that is commonly used to purify damaged water into consumable water. Water purification provides us with safe, pure and clean water to consume and use.
