The National Institute of Ocean Technology (NIOT) is making efforts to make its ongoing water provision project in Lakshadweep eco-friendly by eliminating emissions in its Low Temperature Thermal Desalination technology.

What is LTTD Technology?

• LTTD Technology is a desalination process that uses low-grade thermal energy, typically below 70°C, to evaporate seawater and produce fresh water.
• The technology is designed to be efficient and cost-effective, and it has been successfully used in various locations worldwide to provide potable water.

How does LTTD Technology work?

• LTTD Technology works by using a low-grade thermal source, such as warm seawater, to heat up a chamber containing seawater.
• As the seawater is heated, it evaporates and produces fresh water vapor.
• The vapor is then condensed and collected, leaving behind concentrated seawater, which can be discharged back into the ocean.
• The fresh water produced can be used for various purposes, such as drinking water, irrigation, or industrial applications.

Benefits of this technology

• One of the main benefits of LTTD Technology is that it uses low-grade thermal energy, which is readily available in many locations, especially in coastal areas.
• This makes it a cost-effective and sustainable way of producing fresh water.
• Additionally, LTTD Technology is modular and can be easily scaled up or down, depending on the water demand.
• It also has a relatively low environmental impact compared to other desalination technologies.

Challenges of LTTD Technology

• One of the main challenges of LTTD Technology is that it requires a constant source of low-grade thermal energy, which can be affected by weather conditions and seasonal changes.
• Additionally, the technology is relatively new and may require further research and development to optimize its efficiency and performance.

How is NIOT working to make LTTD Technology emission-free?

• NIOT is working on making LTTD Technology emission-free by using renewable energy sources, such as solar energy, to power the desalination process.
• The goal is to reduce the carbon footprint of the technology and make it more sustainable and environmentally friendly.
