SEDL Achieves Up to 99% Water Recovery Using Advanced LTE Technology
Published on August 29, 2025, by ETManufacturing Desk
Spray Engineering Devices Ltd. (SEDL) has announced a breakthrough in water recovery efficiency through its innovative Low Temperature Evaporation (LTE) technology, which employs Mechanical Vapour Recompression (MVR) to enable up to 99% water reuse. This advancement promises significant benefits for industries heavily reliant on freshwater, including textiles, chemicals, pharmaceuticals, distilleries, and beverages.
Revolutionizing Industrial Water Reuse
Unlike traditional steam-based evaporators, SEDL’s LTE system recycles heat within the process, drastically reducing energy requirements and operational costs. The technology operates at one-fourth the cost of conventional water recovery systems while consuming only 10 to 25 kWh per cubic meter of water treated. Additionally, it curtails sludge production and generates a dry by-product containing less than 10% moisture, which can be safely disposed of or reused depending on the original feed material.
Proven Performance Across Multiple Sectors
SEDL has highlighted several successful applications of the technology:
- Hero Cycles, Ludhiana: Achieved 91% water recovery in electroplating operations with an energy consumption of 20–25 kWh/m³.
- Textile Industry: Garg Acrylics Ltd. (Ludhiana) and Indorama India (Baddi) reported water recovery rates between 97% and 99%, with reduced operational expenses.
- Pharmaceuticals, Dyes, Distilleries, Breweries, and Beverages: The LTE system efficiently treats effluents, enabling substantial water reuse and lowering environmental impact.
Supporting National Initiatives
SEDL emphasizes that its LTE technology aligns with several key national programs:
- Jal Shakti Abhiyan: By facilitating large-scale water reuse, the system supports India’s flagship water conservation initiative.
- Make in India Mission: The enhanced water availability for manufacturing sectors bolsters the country’s drive toward self-reliance.
The company notes particular advantages for the distillery industry, where wastewater generation is substantial due to ethanol blending. LTE technology allows near-total wastewater recovery and reuse, greatly reducing freshwater intake and wastewater discharge.
Recognitions and Patents
SEDL’s water recovery solutions have earned prestigious accolades, including the National Energy Efficiency Innovation Award (2021) and the Confederation of Indian Industry (CII) National Award for Excellence in Water Management (2019). The company holds a patented LTE technology granted by Indian authorities and maintains accreditation from the Department of Scientific and Industrial Research (DSIR).
Conclusion
With rising environmental regulations and increasing freshwater scarcity, industries are seeking sustainable solutions for wastewater management. SEDL’s LTE technology offers an economically viable, energy-efficient path toward Zero Liquid Discharge (ZLD) goals and significant freshwater conservation across diverse industrial sectors.
