Desalination technologies and their environmental impacts: A review
The release of brine is categorized primarily as having EIs because brine is the liquid waste produced during desalination and includes corrosive products, filter backwash, and pretreatment chemicals [59]. A schematic diagram is reported that the environment impacts associated in the desalination operations [93]. Fig 7.

Future reliance on desalination and water reuse to provide suitable drinking water is expected globally. The formation of disinfection byproducts (DBPs) during drinking water chlorination and the compounding factors presented by different sources of fresh water, such as high levels of dissolved organic matter (DOM), is well recognized.
Disinfection by-products in desalinated and blend water ...
The DBPs in desalinated and blend water are an issue due to their possible cancer and non-cancer risks to humans. In this paper, formation and distribution of DBPs in different steps of desalination and water distribution systems prior to reaching the consumer tap were reviewed. The variability of DBPs among different sources and desalination ...
Desalination | U.S. Geological Survey
The process is called desalination, and it is being used more and more around the world to provide people with needed freshwater. Most of the United States has, or can gain access to, ample supplies of freshwater for drinking purposes. But, freshwater can be in short supply in many parts of the Nation and world.
Can Brine from Seawater Desalination Plants Be a Source of Critical ...
The extraction of minerals from hypersaline brines generated as by-products of seawater desalination plants has attracted the interest of scientists. About 18,200 desalination plants operate worldwide with a global cumulative capacity near 90 million m 3 /day [1]. This capacity is expected to grow at an increasingly rapid pace in the …
Desalination
OverviewHistoryApplicationsTechnologiesDesign aspectsCostsEnvironmental concernsHealth aspects
Desalination is a process that removes mineral components from saline water. More generally, desalination is the removal of salts and minerals from a substance. One example is soil desalination. This is important for agriculture. It is possible to desalinate saltwater, especially sea water, to produce water for human consumption or irrigation. The by-product of the desalination process is brine
Desalination and environment: A critical analysis of impacts ...
Desalination is an energy-intensive process that employs energy to produce freshwater from seawater and rejects the brine back to sea. Due to the new desalination activities and the growing number of large facilities around the globe, concerns over potentially unfavorable EIs of the desalination are being evaluated (Baten and …
Evaluating the photochemical reactivity of disinfection byproducts ...
1. Introduction. To combat water scarcity and to meet drinking water needs, approximately 16,000 desalination plants are in operation globally to date, and the majority (69 %) utilize reverse osmosis (RO) technology (Jones et al., 2019).A recent data synthesis study estimated that 142 million m 3 of hypersaline brine wastewater is generated per …
Disinfection by-product formation during seawater desalination: A ...
During seawater desalination, chlorine is the most commonly used disinfectant at intakes to control biofouling in the intake structures, equipment and on RO membranes. Chlorine is typically applied for an initial dose at 0.5–2.0 mg/L or for a target residual at 0.25–0.5 mg/L.
SUSTAINABLE MANAGEMENT OF DESALINATION PLANT …
Desalination concentrate is concentrated seawater. It consists of dissolved compounds found in the ocean (minerals, organics, metals, etc.) that are rejected by the reverse osmosis membranes. Concentrate typically constitutes 90% to 95% of the total desalination plant discharge volume.
Stanford researchers design a more efficient and affordable ...
A new device capable of turning desalination waste into commercially valuable chemicals could make the process cheaper and more environmentally friendly. ... this exemplifies our vision to design water treatment that recovers valuable products from ''waste'' streams using selective separations," Tarpeh said. Will Tarpeh, assistant …
Desalination by reverse osmosis
Desalination by reverse osmosis meets the demands for economic and environmental performance. By 2030, almost one half of the world''s population, or four billion people, will be short of fresh water. Only 3% of the water on Earth by volume is fresh. ... Products and services delivering technical and economic solutions adapted to your needs
Desalination Has a Waste Problem
Desalination is seen as a steady, though energy-hungry and costly, means of satisfying freshwater demands in dry countries. It produces drinkable water by stripping out salts, mostly from sea water but also from brackish groundwater. ... Companies are already developing technologies to convert the salts and metals in brines into usable …
Formation and Fate of Chlorination Byproducts in Desalination …
create new sources of high quality water through reclamation, recycling, reuse, and desalination while protecting public health and the environment. The Foundation sponsors research on all aspects of water reuse, including emerging chemical contaminants, microbiological agents, treatment technologies, salinity management and desalination,
Sustainable seawater desalination: Current status, environmental ...
Seawater desalination is a vital source of freshwater in many regions, but it also poses environmental challenges. This article reviews the current status, environmental implications and future expectations of sustainable seawater desalination, and provides insights for improving its performance and reducing its impact.
Disinfection by-products in desalinated and blend water: formation …
During desalination, feed water is collected through different intakes while open collection systems are widely used. Chlorine (Cl 2) in the form of HOCl or OCl − is typically applied during pretreatment to prevent bacterial growth and biofouling, and to enhance the performance of filters. Pretreatment is performed using continuous or intermittent …
By-product recovery from Saudi desalination plants
The possible production of some by-products from Saudi desalination plants will be discussed in this paper together with the technical feasibility of the proposed processes. INTRODUCTION Desalination in Saudi Arabia started in 1907. The first multistage flash plant, MSF, was built in Doha and Al-Wajh in 1928 with a capacity of …
By-product recovery from Saudi desalination plants
The possible production of some by-products from Saudi desalination plants will be discussed in this paper together with the technical feasibility of the proposed processes. Recommended articles. References (9) J.A. Tallmadge et al. ... Desalination is energy and cost intensive, and concentrate disposal is a significant issue that impedes ...
Frontiers | Characteristics of Desalination Brine and Its Impacts on ...
The design and operation of seawater RO desalination pre-treatment is highly dependent on the quality of feed water, which has an impact on the quality of brine discharged, as lower-quality feed water with high biological activity necessitates more pre-treatment, which necessitates the use of more chemicals such as anti-fouling agents, …
