Experts drew consideration to the prices and damages which will happen after the desalination technique will likely be used to make seawater drinkable given the looming drought threats triggered by local weather change.
Scientific and Technological Research Council of Türkiye (TÜBITAK) Marmara Research Center (MAM) Polar Research Institute General Director professor Burcu Özsoy relating to the modifications they noticed in Antarctica, stated: “We see that terrestrial glaciers have severely separated from the mainland and integrated into the ocean. However, terrestrial ice also poses a great risk as it has the potential to increase sea levels.”
Sea ranges can rise by two totally different mechanisms as a consequence of local weather change. First, because the oceans heat due to an growing international temperature, seawater expands taking on more room within the ocean basin and inflicting an increase in water degree. The second mechanism is the melting of ice over land, which then provides water to the ocean.
The drying up of lakes and different sources of contemporary water in Türkiye has raised considerations because the nation has began receiving alarms for a extreme drought whereas planning for desalination of seawater is into consideration however will or not it’s a secure and wholesome resolution? Let’s learn what our consultants must say to grasp higher.
Normally, there are two major methods to transform seawater into drinkable water: Reverse osmosis or flash desalination. Both require plenty of power and the acquisition of technical science. It’s actually a superb strategy to produce contemporary water. However, it’s not with out considerations from environmentalists who argue that the method shouldn’t be solely costly however causes nice injury to marine life that’s the base layer of the marine meals chain by desalination crops. And for every gallon of contemporary water, a gallon or extra of saline-salty water is returned to the ocean.
Meanwhile, Middle East Technical University (METU) Marine Sciences Institute Director professor Barış Salihoğlu defined that freshwater sources are progressively reducing due to the growing inhabitants and local weather change. He famous that there are a number of levels of seawater purification, which is a technique utilized by many nations within the Mediterranean and Middle East basins to fulfill their water wants.
“First you get the water from the sea, then you have to pretreat it. There may be pollutants, living things and lime in it. After that, the desalination process is started followed by a disinfection method to turn it into drinking water which is pretty costly.”
Pointing out that you will need to select the purpose from which the water is collected to conduct the method, Salihoğlu talked about that, “where the intense salty water that comes out after treatment will be discharged is a matter of discussion as well.” Noting that the salinity of wastewater will be as much as twice the pure salinity, Salihoğlu continued: “Our mannequin research have proven that water collected from barely mid-sea does much less injury than deep-sea habitats.”
Underscoring that in keeping with the brand new laws, such services ought to work with renewable power in opposition to carbon emissions, Salihoğlu emphasised that the primary situation is to show to photo voltaic and wind power within the services.
Expressing concern that Türkiye is a rustic that must be very cautious about its water sources, and that water conservation will be carried out via regulating insurance policies, Salihoğlu expressed that seawater purification will be utilized on the regional degree.
Dokuz Eylul University Engineering Faculty Environmental Engineering Department Environmental Technologies Department lecturer professor Azize Ayol famous that particularly with the event of membrane applied sciences, reverse osmosis techniques have come to the fore within the desalination of seawater.
“The methods of desalination of seawater and treatment of drinking water from seawater have evolved from evaporation technologies to membrane technologies. With this method, you can completely desalinate water,” Ayol defined.
Ayol added, “such facilities have been operating in many countries of the world for a long time and are used in Israel, Saudi Arabia, Spain, Canary Islands, the U.S. and Australia, reminding that there is a facility that purifies seawater on Avşa Island in Türkiye.”
“If you’re a nation fighting water shortage and funding prices, set up this method as a result of you do not have water. The price varies in keeping with the area and power wants. The bigger the ability capability, the decrease the preliminary funding prices. The high quality of the seawater you obtain can also be necessary. Different pretreatments are utilized for these services. These are the processes that have an effect on the preliminary funding prices. Membrane know-how is creating rapidly. As this improves, the fee will enhance too.”
Touching upon the working price aside from the funding, Ayol famous that, “the operating cost for 1 cubic meter of clean water varies between 30 to 90 cents. We need to purify and process this water separately. In developing technologies, it is possible to obtain energy by utilizing the hydrostatic pressure in the concentrated stream and use it in the facility’s operation because the cost decreases when energy-efficient facilities are established,” she defined.
Saying that Türkiye is experiencing “water scarcity,” Ayol stated that the nation’s want for ingesting water is 7-8 billion cubic meters per yr, and though this want will be met with present sources, there are occasional issues in coastal areas, particularly in summer time, and that seawater shouldn’t be obtainable in such locations, indicating that the purification technique might be utilized in such conditions.”
Regarding the widespread use of seawater therapy know-how in Türkiye, Ayol stated: “It is not a critical need, it is important for us to use conventional water resources, to prevent loss and leakage and to use water resources more economically and efficiently,” she emphasised.
