We analyzed and extracted the information using text analysis. And last but not least, even if these local imbalances may cause concern. A new report from the Pacific Institute examines effects on the marine environment associated with the construction and long-term operation of seawater desalination plants, including withdrawing water from the ocean and discharging the highly concentrated brine. It evaluates the potential impacts to air, land, and marine environments and also proposes mitigation measures to reduce environmental impacts. The goal of our research topic is to weigh the pros and cons of desalination and find out the impacts of desalination on the environment. ( Log Out / The different desalination technologies are associated with different water recovery ratios. 2016, futureofworking.com/6-advantages-and-disadvantages-of-desalination/. The latter generates of course a great amount of GHG which are going to have an impact – actually a negative impact – on the climate and on the water cycle. Further, the … The total world production of fresh water from the sea is about 2621 mgd (9.92 million m(3) day(-1) 1985 figures). These studies analyse the possible impact of the brine in depth. Desalination, like other major industrial processes, has environmental impacts that must be understood and mitigated. As the world's driest countries turn to desalination technology to quench their thirst for fresh water, a new environmental problem is growing: what to do with the brine created from treating fresh sea water? “Existing and Proposed Seawater Desalination Plants in California.” Pacific Institute, May 2016, pacinst.org/publication/key-issues-in-seawater-desalination-proposed-facilities/. Sustainable Water Integrated Management (SWIM) - Support Mechanism Project funded by the European Union. ( Log Out / Torrevieja Desalination Plant (Image: ACUAMED). And massive strides are being taken to account for any environmental impact the plant may have. We also accessed articles from websites such as Occupy Theory, Future of Working, Science Direct, Pacific Institute and Carlsbad Desal. ( Log Out / Brine can cut levels of oxygen in seawater near desalination plants with “profound impacts” on shellfish, crabs and other creatures on the seabed. Additionally, desalination is not dependent on other factors such as rain and snowfall to operate; it can produce drinking water and in extreme cases, provide water for agricultural irrigation in arid areas. against building desalination plants on the grounds of environmental impacts to the surrounding area, especially to marine life due to the high concentrated brine discharge that diffuses back into the ocean. Beginning in the 1920s, … If the ocean were tapped as a source of fresh water, what impact would that have on the environment? So, it is important that we need to understand the positive and negative impacts on human and the environment that desalination can cause. At the same time, though, we have to address potentially severe downsides of desalination - the harm of brine and chemical pollution to the marine environment and human health," said Dr … With developments in modern methods, such as reverse osmosis however, desalination plants can now produce enough potable water … Arguably best known is the copious amount of fossil fuels that … Discourse and desalination: Potential impacts of proposed climate change adaptation interventions in the Arizona-Sonora border region. There are numerous Spanish and international studies that confirm the harmlessness of the brine in the marine environment when the discharges are carried out correctly. Desalination provides a climate-independent source of water for critical human needs and economic development (industry and agriculture in particular). Its method is proven and effective. First, seawater is abundant and it covers about seventy percent of the earth’s surface; it never runs out. Increased energy cost and developments in … During the desalination process, half of the collected water will end up as fresh water. Environmental issues in seawater reverse osmosis desalination: Intakes and outfalls. Spanish Association of Desalination and Reuse (AEDyR), is the leading organization dedicated to desalination and water reuse in Spain. Also, to mitigate concerns over the depositing of brine back into the ocean, a state-of-the-art diffuser technology is being implemented to keep salinity within the range of the new and strict standards are put forth by the Desalination Amendment. “Desalination Pros and Cons List.” OccupyTheory, 19 June 2015, occupytheory.org/desalination-pros-and-cons-list/. ( Log Out / Fortunately, water is also... 2. Note that 2020 Impact Factor are reported in 2021; they cannot be calculated until all of the 2020 publications have been processed by the indexing agency. However, the responsible authorities must understand how desalination affects the environment. Water is the most valuable natural resource and is vital for all species. Desalination, he explains, can have a number of potentially deleterious environmental impacts. Also, during the outfalls process, the environmental risks include discharge of metals from corrosion (Cu, Fe, Ni, Mo, Cr), impacts to aquifers from leaks from brine pipes, discharge of chemicals used for pre-treatment and membrane cleaning, and permanent damage from emplacement of infrastructure. List of Pros of Desalination. Change ), You are commenting using your Facebook account. Desalination plants might operate at a reasonable price, but building them isn’t always feasible for a community or a nation. The Huntington Desalination will be the first desalination plant in California to be one-hundred percent carbon neutral. First of all, the Spanish Association of Desalination and Reuse (AEDyR) considers that desalination and reuse of water play a key role to solve the problems of water-scarcity suffered by many countries and regions in the world today and will do so in the future. Due to the serious drought issue in California, desalination is increasingly being considered by California coastal cities to be a good solution and an alternative way to augment water supplies. CSULB Student’s Perceptions of Single Use Plastic, Follow Environmental Geography on WordPress.com. Change ). environmental impacts. In conclusion, desalination is starting to become a popular solution to fight the California drought even though it will come with environmental risks and impacts. is only possible through co-located operation with power plants. Environmental impact of desalination technologies: A review 1. This blog highlights research projects conducted by undergraduate students enrolled in the course Environmental Geography at California State University, Long Beach under the supervision of Dr. Lily House-Peters. The present research is focused on the environmental issue observations and modeling based on dissolved trace metals, hydrographic parameters, and nutrients at the discharging plume and nearby locations of Rabig desalination plant (RDP) and Yanbu desalination plant (YDP) … She primarily researches a membrane process called pressure-retarded osmosis, or PRO. The EIA considers all environmental parameters and criteria. It’s proven to be effective: removing salt from seawater is a system that has been in practise on board ships as far back as ancient times. So, it is important that we need to understand the positive and negative impacts on human and the environment that desalination can cause. 2. Furthermore, the process increases the atmospheric temperatures in Abu Dhabi. Recovery ratios increase when salinity of the intake water decreases, and consequently decrease when salinity is higher. Plata wants to reduce the environmental impact of water desalination by reducing the amount of brine released to the environment, along with the amount of energy expended in the process. Or, in most instances, desalination is made to counteract the water cycle and climatic change vagaries. Desalination, Drought, Energy, Ocean/Marine, Southern California, Water, Project Researchers & Authors: Harim Lee, Andy Meechukant, Gabriela Alcala, Alexander Sanchez, and Alex Forest. “Carlsbad Desal Plant.” Carlsbad Desal Plant, http://www.carlsbaddesal.com/.

Environmental Impact … Parts of the machinery contain pumps constructed under the sea which can affect currents and waves. Membrane desalination process. “Huntington Beach Desalination Project.” Huntington Beach Desalination Project, 9 May 2017, waterboards.ca.gov. Without entering into assessments on these figures, it is important to consider that this geographical area is also where the greatest amount of large thermal desalination plants are concentrated. Some argue desalination is a good solution for drought and reduces the need for water to be imported or exported to other areas. Brine, water comprising about 5% salt, often includes toxins such as chlorine and copperused in desalination which accumulate in the environment and can have toxic effects in fish. Desalination may also include the environmental benefit of reducing our unsustainable reliance and over-drafting of rivers, streams and aquifers, thereby reducing the adverse environmental impacts on those resources. Desalination is a reliable technology that has been long used internationally in countries including Saudi Arabia, the UAE and many others. While desalination has positive effects on the potential irrigation water quantity and quality, the technique may also be a considered potential source of groundwater pollution. Desalination remains in Saudi Arabia the supreme viable alternative to boost the future water supply requirements. The state of desalination and brine production: A global outlook, SWPC appoints Engie consortium as preferred bidder for Jubail 3B desalination project, SWPC announces proposals received for the Madinah 3 Independent Sewage Treatment Plant. The cost is high enough that it has prevented development of this technology because many just can’t afford the initial price tag and there aren’t enough returns to justify the investment. The study "The state of desalination and brine production: A global outlook” was recently published in the journal Science of the Total Environment, and had a great impact on Spanish and international media. Again, the maintenance and operation are costly, and building a desalination plant is highly expensive costing millions or billions of dollars. In the present study, some consideration is given to the feasibility of desalination, as well as the effectiveness of water savings measures to reduce desalination and energy requirements, for illustrative purposes. environmental impacts, removing some of the impediments for the use of fossil fuel or renewable energy sources. McEvoy, J., & Wilder, M. (2012). Due to the serious drought issue in California, desalination is increasingly being considered by California coastal cities to be a good solution and an alternative way to augment water supplies. 1. The implication, therefore, is that desalination requires immediate interventions that will minimize its chemical and temperature effects on the environment. Extending membrane life is likely to have a very small impact on desalination costs. 2. emitted from desalination of Mediterranean seawater during 2013 is equivalent to putting 3.3 Million new cars on the roads or burning a volume of petrol slightly over 24 Million liters/day. It is technically more complex and expensive to operate with a high recovery ratio when the intake water has higher salinity. This study proceeds in the following steps: • A scenario of future (2030) water scarcity (chapter 2) Currently, neither of these distillation techniques is less harmful, or more productive than conventional desalination. Brine waste, added with chlorine and anti-scaling agents during processing, are usually dumped back in the ocean harming the marine organism. “6 Advantages and Disadvantages of Desalination.” FutureofWorking.com, 1 Mar. Therefore, AEDyR actively encourage, to the extent of our resources, this aspect. Our research topic also links to the concept of the 4 stages of critical risk analysis that we learned in class in the way that it foresees what to expect, what to avoid, and how to manage the negative consequences of desalination. To gather important and reliable information about desalination, we used two peer reviewed research articles Environmental Issues in Seawater Reverse Osmosis Desalination: Intakes and Outfalls by Thomas M. Missimer and Robert G. Maliva, and Discourse and Desalination: Potential Impacts of Proposed Climate Change Adaptation Interventions in the Arizona-Sonora Border Region by Jamie McEvoy and Margaret Wilder. Reverse osmosis, a method of removing salt from seawater has been proven effective in creating fresh sources of drinking water that can deliver the health benefits people need. These studies analyse the possible impact of the brine in depth. To know more about this, we invite you to watch the documentary produced by AEDyR "History of desalination in Spain”, in which one chapter analyses the environmental sensitivity of desalination in Spain. Sklar, Eric. All desalination plants are subject to periodic feasibility and environmental impact studies approved by a competent authority.
