Desalination technology, which generates freshwater by eliminating salt and other mineral components from seawater, has emerged as one of the world's most important water treatment, and drinking water production technologies.
As a result, many researchers are working on effective techniques for seawater desalination.
Alternative techniques for the Seawater Desalination
The requirement stems from the fact that desalination technology is prohibitively expensive in many countries. The treatment processes are high-maintenance, requiring strict wastewater disposal and feed water supply regulations to be met.
This can be difficult for many countries to achieve. With the current situation, where the number of people experiencing water stress is increasing by the day, choices for nations that are not financially strong must be provided.
What are the issues related to seawater desalination?
One of the major challenges that a lot of countries confront is the fact that, they are unable to afford the costs associated with seawater desalination, in order to ease some of the strain on natural resources.
Currently, seawater desalination employs the fundamental reverse osmosis technology, which involves passing polluted or saline water through a semi-permeable membrane, to obtain pure water on the other side.
But, at what price?
· Excessive energy use,
· Concerns about the environment include:
· (a) the disposal of highly concentrated brine, and
· (b) the supply of energy, which is primarily derived from fossil fuels.
In terms of energy usage, excess heat from the multi-stage flash process is recovered, and reverse osmosis pressure is returned to the system. Early systems have already benefited significantly from this.
Cost analysis
While, it works on a domestic and even commercial scale, membranes on a bigger scale are expensive due to their sophisticated design. Furthermore, a single desalination plant contains at least 40,000 of these membranes. This is a sobering concept for developing countries, with fragile economies.
As a result of the budgetary constraints, underdeveloped and emerging countries may find reverse osmosis to be costly. Despite, the fact that the process is among the most expensive in the world, on-going attempts are being made to keep the choice available to everyone.
Is metal-organic framework analternative to Seawater Desalination?
Certain features of metal-organic frameworks (MOFs) may improve conventional desalination processes. Their porous hollow architecture enables surface adsorption/desorption, and molecular sieving applications in gaseous and liquid environments.
Adsorption
MOFs have excellent adsorption-desorption properties, allowing them to collect and release water with minimal energy input. Furthermore, at specified pH values, they utilize their entire adsorption potential.
A water desalination method based on evaporation-adsorption/desorption-condensation cycles, might thus be tailored to local conditions. The minimal energy required for desorption, in particular, could offer a significant improvement over present systems.
Conclusion
Sustainable water treatment and desalination alternatives are required, to provide drinkable water to humans, livestock, and crops. Existing solutions have disadvantages and could be enhanced, or replaced by metal-organic framework-based technologies.
These relatively novel materials have a lot of promise for adsorption-based or molecular sieving applications. We believe in the ability of metal-organic frameworks, to guarantee drinking water sources in all parts of the world, whether they are desert, humid tropical or sub-tropical, or industrially contaminated.
