What is the cost of setting up desalination plant?
Cost of course depends on capacity and desalination method. Shoaiba Desalination Plant, Saudi Arabia, uses MSF Flash technology with a total output capcity of 128 million gallons per day. Cost 1.6 billion $US.
What are the cons of thermal desalination?
Advantages· Distillation offers significant savings in operational and maintenance costs compared with other desalination technologies. · In most cases, distillation does not require the addition of chemicals or water softening agents to pretreat feedwater.· Low temperature distillation plants are energy-efficient and cost-effective to operate.· Many plants are fully automated and require a limited number of personnel to operate.· Distillation has minimal environmental impacts, although brine disposal must be considered in the plant design.· The technology produces high-quality water, in some cases having less than 10 mg/1 of total dissolved solids.· Distillation can be combined with other processes, such as using heat energy from an electric-power generation plant.Disadvantages· Some distillation processes are energy-intensive, particularly the large-capacity plants. «Disposal of the brine is a problem in many regions. · The distillation process, particularly MSF distillation, is very costly.· Distillation requires a high level of technical knowledge to design and operate.· The technology requires the use of chemical products, such as acids, that need special handling.
What is calcium carbonate scale and calcium sulphate scale in desalination plant?
Scale formation represents a major operational problem encountered in thermal desalination plants. Scale may form because of the composition of the make-up, but mostly develops as a result of further change occurring during evaporation. Scale formation is mainly caused by crystallization of alkaline scales, e.g., CaCO3 and Mg(OH)2 and non-alkaline scale, e.g., CaSO4. The formation of CaCO3 scale strongly depends on temperature, pH, and the release rate of CO2 as well as on the concentrations of HCO3-, CO32-, Ca2+, and Mg2+ ions. Scaling in industrial processes is affected by the following factors: (i) bulk variables and composition, i.e. CaCO3 precipitation potential, pH buffering capacity, chloride and sulfate concentrations and concentration of dissolved oxygen, (ii) thermal effect, i.e. heat flux, surface temperature and bulk temperature, (iii) flow field, i.e. velocity of flow and solid/liquid interface conditions and (iv) substrate properties, i.e. materials properties and surface conditions.In previous works, Al-Rawajfeh et al. [1-3] have modeled the CO2 release rates in multiple-effect distillers (MED)distillers. This model did not account for the deposition of alkaline scale and its effect on CO2 release rates. Calcium carbonate and magnesium hydroxide were assumed to precipitate at negligible rates. Recently, Al-Rawajfeh [4,5] developed a model to simulate the simultaneous release of CO2 with the deposition of CaCO3 and investigated their mutual release-deposition relationship in MED [4] and in the flash chambers in MSF distillers [5]. The influence of CO2 injection on the carbonate chemistry and the scale formation were also studied [6]. The model begin to calculate the CaCO3-Mg(OH)2 (alkaline) scale in the brine chambers, because part of the scale is deposited there and will be reduced from the total scale precipitate or reduce the ions available to precipitate CaSO4 scale inside the tubes when it is recycled with the make-up. Details on the CO2 release and alkaline scale modeling can be found in previous works [1-6].REFERENCES[1] Al-Rawajfeh, A.

Where is it Medecins Sans Frontieres?
Médecins Sans Frontières MSF (Doctors Without Borders) is an independent international medical humanitarian organisation that delivers emergency aid in more than 60 countries to people affected by armed conflict, epidemics, natural or man-made disasters or exclusion from healthcare. In emergencies and their aftermath, MSF rehabilitates and runs hospitals and clinics, performs surgery, battles epidemics, carries out vaccination campaigns, operates feeding centres for malnourished children and offers mental healthcare. When needed, MSF also constructs wells, dispenses clean drinking water and provides shelter materials, such as blankets and plastic sheeting. Through longer term programmes, MSF treats patients with infectious diseases such as tuberculosis, sleeping sickness and HIV/AIDS and provides medical and psychological care to marginalised groups, such as street children. Founded by doctors and journalists in 1971, MSF is now a worldwide movement with offices in 19 countries and an international coordination office in Geneva, Switzerland. As an independent and self-directed organisation, MSF's actions are guided by medical ethics and the principles of neutrality and impartiality. This means that MSF offers assistance to people based only on need and irrespective of race, religion, gender or political affiliation. MSF strives to ensure that we have the power to freely evaluate medical needs, to access populations without restriction and to directly control the aid we provide giving priority to those in most grave danger. MSF does not take sides in armed conflict and insists on unhindered access to patients. When MSF is witness to massive and neglected acts of violence against individuals and groups, we may speak out publicly based on eyewitness accounts, medical data and experience. The work of MSF is carried out by over 25,000 health professionals, logistics experts and administrative staff who run projects in approximately 65 countries around the world. The MSF movement was awarded the 1999 Nobel Peace Prize.
What does the medical abbreviation MSF mean?
MSF in a medical context can stand for "multiple system failure," which refers to the simultaneous failure of multiple organ systems in the body that causes a person to be in critical condition. It can also stand for "morphine sulfate and furosemide," which are two medications commonly used in healthcare settings.

What is marginal standing facility?
MSF is the rate at which banks can borrow overnight from RBI.This was introduced in the monetary policy of RBI for the year 2011-2012. The MSF is pegged 100bps or a % above the repo rate. Banks can borrow funds through MSF when there is a considerable shortfall of liquidity. This measure has been introduced by RBI to regulate short-term asset liability mismatches more effectively
