Spray Engineering Devices Ltd. (SED), one of India’s leading innovative engineering companies, has successfully commissioned its patented Low-Temperature Evaporation (LTE) ZLD system powered by Mechanical Vapor Recompression (MVR) technology at two Coca-Cola’s greenfield bottling facilities in Jammu – NJ Food LLP, Samba, and Kandhari Beverages Pvt. Ltd., Kathua. The installations mark a major advancement in industrial waste water recovery and reuse, enabling both plants to achieve complete Zero Liquid Discharge (ZLD) without relying on conventional Effluent Treatment Plants (ETPs).

The LTE system treats raw, complex wastewater directly at low temperatures (60°C–65°C) under vacuum, with recycling of heat within the process to maximize efficiency. With energy consumption as low as 13–15 kWh/m³ of feed, the system significantly lowers operational costs while producing clean, reusable condensate water of low Total Dissolved Solids (TDS).

Vivek Verma, managing director, SED said, “This project demonstrates how advanced innovative solutions can deliver measurable environmental impact while strengthening business resilience. By partnering with Coca-Cola’s bottling facilities in Jammu, we are showcasing how industries can achieve Zero Liquid Discharge in the most energy-efficient and economically viable manner.”

With its compact, modular design, the LTE system eliminates the need for bulky ETP, RO, boiler, and cooling-tower infrastructure – facilitating faster deployment, a smaller footprint, and reduced operational complexity. It also enables recovery of dissolved solids such as salts and sugars, advancing a “waste-to-wealth” model and reducing industrial freshwater dependency.

J. S. Kandhari, managing director, Khandhari Group added “We are satisfied with our decision to replace the conventional ETP with an innovative MVR-based LTE technology. This transition has enabled efficient recovery and reuse of wastewater across our plants, significantly reducing freshwater consumption while ensuring full compliance with Zero Liquid Discharge (ZLD) norms through a state-of-the-art system.”
