Overview of Status and Key Challenges for Use of Unconventional Sources of Drinking Water
Chapter
Discharge from desalination plants is constituted mainly from reverse osmosis (RO) concentrate but may also contain filter backwash water and spent cleaning solutions used for membrane cleaning. The quantity and quality of each discharge component can be calculated based on the plant source water quality and process performance characteristics. The...
Chapter
Disposal of concentrate to land application is suitable only for small desalination plants, located in arid climate, where land is available for infiltration, or where salt-tolerant plants are in abundance. Regional groundwater basin water quality impacts would also have to be assessed for possible detrimental impacts of infiltration. Agricultural...
Chapter
Desalination is becoming increasingly popular for the production of fresh potable water due to the elevated risk of water scarcity as a result of climate change and growth in demand, especially in highly urbanized coastal regions. As the number of plants and volumes of desalinated water increase, assurance must be provided for the environmental sus...
Chapter
Given the comparatively high cost of concentrate management, benefits can be obtained by consolidating effluent from a number of sources to provide infrastructure that minimizes environmental impact while taking advantage of economies of scale. Using a variety of sources and types of effluent (i.e., brackish and seawater) has the advantage of dilut...
Chapter
Surface water discharge is the most common desalination plant concentrate disposal practice. As the number of developments and volumes of desalinated water increases, assurances must be provided for the environmental sustainability of such discharges over extended time periods. Potential environmental impacts can be minimized through the mixing of...
Chapter
Under certain favorable conditions, concentrate can be disposed of in evaporation ponds, where water is evaporated through solar irradiation and heating, while the remaining salts can be disposed of to landfill from time to time. Required land area is dependent on the volume of concentrate. Storage pond redundancy is required to allow for clearing...
Chapter
This chapter compares the concentrate management alternatives described in the previous chapters and presents criteria and methodology for selection of the most suitable management approach for the site-specific conditions of a given project. Each method of concentrate disposal has advantages and disadvantages, which are highly site-specific. The a...
Chapter
Concentrate from small desalination plants can be disposed of in deep confined saline aquifers which are proven to be geologically suitable. The capacity of such aquifers is limited by permeability and transmissivity, and the requirement that the underground injection zone water quality must be compatible with the water quality of the desalination...
Chapter
Finding value in desalination concentrate is a growing field of interest with a worldwide sustainability focus on the circular economy. Recent trends in beneficial use of concentrate includes extraction of minerals and rare metals for generation of construction materials and other products. Concentrate from desalination plants contains dissolved io...
Chapter
This chapter provides an overview of the most common practices for management of nonconcentrate residuals in desalination plants such as spent pretreatment filter backwash, MF and UF pretreatment and RO membrane cleaning solutions. Other sidestreams include rinsing water off pretreatment filters and lime clarifier sludge or backwash water from lime...
Chapter
Zero-liquid discharge disposal systems require brine concentration to be reduced to pure water and solids, which can be disposed of either for commercial purposes or to landfill. Process intensification combines a number of existing processes to improve the recovery, and disruptive technologies are likely to be necessary to significantly reduce cos...
Chapter

The respective plants, receiving water bodies and discharge characteristics, are summarized. Permitting practices vary not only among countries, but also within, as new pla...
Chapter
Discharge of desalination plants to wastewater systems is a disposal practice frequently used at small-size desalination plants, and is usually feasible where the volume of concentrate discharged to the receiving wastewater treatment plant (WWTP) is at least an order of magnitude smaller than the volume of plant raw wastewater influent. The cost of...

Questions

Questions (8)
Question
Could you identify references/publications for state-of-the-art technologies for cost effective treatment of brine generated from seawater to product of 99.6% content of Sodium Chloride? The main challenges are the removal oc calcium, magnesium, potassium, fluoride, boron, bromide and strontium - all of them have to be less than 5 mg/L in the brine.
Question
Reverse Electrodialysis seems to have some advantages over pressure retarded osmosis - would it be a more efficient technology for energy generation than pressure retarded osmosis assuming the use of brine from seawater desalination plants as high-salinity stream and treated wastewater as a low-salinity stream.  Any publications on comparative cost analysis of the two technologies?
Question
Please find attached a link to the latest issue of the Science News article on some of the latest desalination technologies.  What do you think about the referenced technologies?
 
 
Question
Do you have any full-scale examples of SWRO desalination plants which use membrane pretreatment followed by cartridge filtration? What is your opinion of the benefit of cartridge filtration downstream of membrane pretreatment?
Question
Chlorine dioxide is known not to cause oxidation of SWRO membranes. However, equipment for onsite generation of chlorine dioxide is also known to potentially produce sodium hypochlorite, which could cause loss of membrane integrity over time. Any full-scale experience?
