Ramachandran, Ashwini Murugan REST Labs, Kaveripattinam, Krishnagiri, Tamil Nadu, India. *Corresponding author Email: chandrasekarrsri@gmail.com Abstract. Desalination plants produce around 25 mm3 of water every day to meet the world's water demand. These "water factories" have a capacity ranging up to 230,000 m3/d, and they can supply large cities with drinking water. However, it is well-known that desalination plants are often large industrial facilities that require a lot of space and emit large amounts of combustion gases. The plant type, capacity, design, and expansion capacity vary across Western Australia, South Australia, Victoria, New South Wales, Queensland, and the Northern Territory. As a result, it has been found that the Northern Territory ranks first, while Victoria ranks the lowest. Using the MOORA Method, a range of desalination plants can be evaluated, and the results show that the Northern Territory is at the top of the ranking. Keywords: MCDM, Plant type, Capacity and Design expansion capacity. 1. INTRODUCTION Desalination is any process that removes salts from water is defined. Desalination processes municipal, in industrial or commercial applications can be used. With the advancements in technology, Desalination processes for our growing needs Others that produce usable water are becoming cost-competitive with methods. Desalination is any removal of salts from water also defined as process. Desalination Processes are municipal, industrial or commercial can be used in applications. Of technology with improvements, our desalination processes are growing Produce water that can be used for future needs are becoming cost-competitive with other methods of doing so. Duplex grades are available the same or even more so than their austenitic counterpart’s Excellent corrosion resistance. They are more powerful, at least twice the size, weight and Cost of austenitic grades. Reductions. Many in desalination Applications, membrane and filtration processes the paper describes both, in which Advantages of Duplex Stainless Steels are exploited. Four major engineered duplexes Heat that stainless steels are a cost-effective alternative Companies involved in desalination have realised. For traditional materials for such plants. Multi-objective optimization ratio analysis (MOORA) method by Brauers in 2004 introduced. Evaluation of the parameters of the industries, maintenance system it is very important to do, the main purpose of which is continuity Designing development plans is operational Helps maintain processes efficiently. In this regard, we will use in the present research the proposed method is called MOORA Criterion is decision-making. Also, during the process Maintenance using collected metric data we analyze and evaluate the system we propose 2. DESALINATION PLANTS Australia is the driest continent on Earth However the total of the world 1% of desalination capacity Desalination capacity is installed. This article describes each desalination the main sea also considered in the plan Investigates water issues. Ocean currents, sea water temperature and salinity are significant indicators evaluating desalination feasibility because they affect production costs, maintenance frequency, and Product water quality. Seawater reverse osmosis (SWRO) is in Australia Large-scale desalination in the future currently used for plants or proposed desalination [1]. It is inclusive/hybrid is a membrane structure works to reduce and remedy those issues. This additionally applies to SWRO desalination flora. Conventional pre-remedy in stopping abuses Not useful the for RO membrane and RO Solid Feed Unable to produce gadget. By incorporating an integrated/hybrid membrane device before treatment, these problems can be reduced.
