The first stage involves the removal of solid and liquid particles through filtration. Sydney Water mainly uses ferric chloride to prevent the recurrence of murky water. They also use small amounts of long chain polymers (polyelectrolyte) as a secondary coagulant. It is then followed by the inactivation of microorganisms; to which all monitored filtering plants uses a strong oxidant for disinfection (in Sydney Water, chlorine is used). The last stage involves the addition of fluoride to the water to fulfil the requirements of the Fluoridation of Public Water Supplies Act 1957. This, along with the added lime and carbon dioxide, reduces the corrosivity of

Today, desalination is a common process that's used in seaside cities and towns worldwide. There are more than 15,000 desalination plants around the world providing freshwater from salt and brackish water alike (Planet Green 2011). This number continues to grow as researchers work to improve the process, both in terms of cost effectiveness and energy efficiency (DSE 2011). But countries such as Australia, Israel and even the United States are continually adding desalination plants of various sorts into their water-management portfolios. The facilities are common in North Africa and the Mideast, where freshwater is scarce (Chandler 2008).

1. There are two main sources of fresh drinking water, ground water and surface water. Ground water originates from precipitations that usually fall in the form of snow or rain. While, the surface water is also originates from precipitate that reaches the land surface and is then recharged into rivers, wetlands and lakes. Although these systems are usually reliable, in desperate time of need, a more reliable source of water is needed. The desalination plant is extremely valuable and flexible because it does not depend on rainfall. Instead, the desalination plant is the only source that relies on seawater. Using seawater in the desalination plant helps meet the community’s water needs and secures the water needs in the future. While other sources of water, such as rainwater or water from dames are not reliable enough to strictly rely

We've all seen the overzealous sailors who wash down their boat after every two-hour sail, but did you realize they might actually be on to something? As it turns out, salt water can cause problems we'd do better to avoid. For example, have you ever noticed how your stainless remains mostly, free of rust, also called pox, when you hang at the marina? However, take your boat out for a couple months, and you may start to form a less than optimistic picture. Suddenly, your stainless boat starts to crop a fresh set of pox. Truth be told—it comes from the salt.

Desalination has been used for hundreds of decades, Greek sailors heated water to evaporate fresh water away from the salt and other minerals, and the Romans used some clay filters to trap salt. Today's urbane methods still mostly use the concepts of distillation or filtration. The procedure of desalinating sea water to produce drinkable fluid has a long and gorgeous history. Nevertheless, the first significant modern desalination process to perform was multi-stage flash distillation type (MSF) it is a process that originally started during the mid-20th century in the USA (1955). Moreover, even though multi-effect distillation had been revealed and had the potential to be more effective than multi-stage flash desalination (MSF), it took a

At present, Lucas Energy (is a publicly traded oil and gas company) collects the water produced by the wells at it’s Stratford Pilot Project in lined storage dams on site. Some have a high salt content (greater than 5000 parts per million) which is stored separately from the remainder ( which have a lower salt content). Lucas has approval from the Department of Primary Industries (DPI) to use the low content salt water for irrigation under certain conditions which ensures that there is no detrimental impact on the condition of local soils and groundwater. The water is also used during daily operation for activities such as dust suppression and drilling.

After years of water shortages plaguing the southeast of Queensland the state government decided to build a desalination plant, at Tugun, on the Gold Coast in 2009. After only 2 months after the taps were finally turned on, the State Government’s $1.2 billion desalination plant was shut down for five weeks of repair. (task sheet) The main problem the desalination plant faced was corrosion. The two giant stainless tanks used to store desalinated water had to be replaced because of corrosion and more than 100m of rusting pipe had to be replaced.

In this project, parameters such as turbidity, COD, BOD, TSS and pH were measured where turbidity was measured according to the turbidity meter (2100N, HACH, USA) procedure meanwhile pH was measured according to pH meter (Crison pH 25) procedure. 3.8.1

Hello everyone, this is Mohammed Uddin. I am a sophomore at Penn State Brandywine. Today I am going to talk about how the ocean water is desalinated to drinking water. Desalination, or what is commonly known as desalting, is a process which removes salt and other impurities from seawater to produce fresh water. Many countries are using desalination as of way to have more reliable fresh water. Some of the countries that are currently using desalination plants are Algeria, Aruba, Australia, United Arab emirates, United kingdom, United States.[3] The process involves forcing water molecules through semipermeable membranes, much like a filter in a coffee maker, to remove salts and other impurities such as minerals and bacterials. In 1791 Thomas

Water desalination processes separate dissolved salts and other minerals from water. Feed water sources may include brackish, seawater, wells, surface (rivers and streams), wastewater, and industrial feed and process waters. Membrane separation requires driving forces including pressure (applied and vapor), electric potential, and concentration to overcome natural osmotic pressures and effectively force water through membrane processes. As such, the technology is energy intensive and research is continually evolving to improve efficiency and reduce energy consumption.

The ions, Na+Cl- , that enter the mud system as a result of drilling salt sections or from formation saltwater flow cause a mud to have high yield strength, high fluid loss, and pH decrease. Some actions for treatment are dilution with fresh water, the use of dispersants and fluid-loss chemicals, or conversion to a mud that tolerates the problem if the cost of treatment becomes
