VAPOZEM

Rethinking the Energy Balance of Evaporation

VAPOZEM from Diva Envitec Pvt Ltd offers a comprehensive range of evaporation systems designed for energy-efficient concentration, crystallisation, and Zero Liquid Discharge (ZLD). Built around Mechanical Vapor Recompression (MVR) and hybrid evaporation technologies, VAPOZEM significantly reduces steam consumption by recycling vapours, making it ideal for high TDS and high-volume wastewater treatment applications.

Vapour Recompression Cycle & Thermal Integration

Mechanical Vapor Recompression (MVR)
recompresses vapour using electrical energy, recycling latent heat and drastically reducing steam consumption.
Thermal Vapor Recompression (TVR)
uses steam ejectors to reuse vapour energy, suitable where high-pressure steam is available.
Evaporation mechanisms
includes falling film, forced circulation, and hybrid systems to handle varying feed characteristics and scaling tendencies.
Drying & solid handling (ATFD)
agitated thin-film dryers convert concentrated slurry into dry solids for complete ZLD compliance.
Retrofit & hybrid integration
existing MEE systems can be upgraded to MVR-based systems for improved energy efficiency and lower operating costs.

Energy Performance & Evaporation Advantages

Engineering Considerations

Conventional evaporation systems are energy-intensive. MVR-based systems can reduce steam consumption by up to 80-90% by reusing latent heat, making them a preferred choice for modern ZLD and sustainable industrial operations.
