Overview:
Mechanical Vapor Recompression (MVR), also known as Mechanical Vapor Compression (MVC), is an energy-efficient evaporation method where a compressor increases the pressure and temperature of the steam produced. This elevated steam then serves as the heating medium for the liquid being concentrated, making the evaporation process highly efficient. MVR is particularly effective for the treatment and recycling of wastewater with high COD, high salts, and high volatile organics.
Benefits and Applications of MVR Technology
Product Features:
- Requires minimal or no live steam.
- Low energy and operational costs.
- Can be combined with a crystallizer for continuous evaporation and crystallization.
- Condenser requirements are minimal or non-existent.
Applications:
In partnership with Singapore-based Pioneer Environmental Technology, Suswen offers MVR systems designed for the integrated treatment and recycling of complex wastewater streams. This technology effectively handles high COD, high salts, and high volatile organics by:
- Volatile COD Removal: Using a stripping column, volatile organic compounds are stripped off by steam, condensed, and recovered.
- Non-Volatile COD and Salts Removal: Non-volatile organics and salts are separated through the evaporation or MVR process, where vapor is recompressed to generate high-temperature, high-pressure steam, recycling the heat content.
Through this integrated process, most COD and salts are efficiently removed, allowing the purified water to undergo further physical/chemical or biological treatment to meet discharge standards or be recycled. This technology enables zero liquid discharge, making it ideal for treating difficult wastewater streams.
In conclusion, Mechanical Vapour Re-compression (MVR) offers a sustainable, cost-effective, and energy-efficient solution for the recovery and re-use of steam or vapor in industrial processes, contributing to improved resource utilization and environmental stewardship.
Frequently Asked Questions
Mechanical Vapor Recompression (MVR) is an energy-efficient evaporation process where a compressor increases the pressure and temperature of steam. The elevated steam serves as the heating medium for the liquid being concentrated, making the process highly efficient in treating and recycling wastewater with high COD, salts, and volatile organics.
The MVR systems, offered in partnership with Pioneer Environmental Technology, provide benefits such as minimal or no live steam requirement, low energy and operational costs, and the ability to combine with crystallizers for continuous evaporation and crystallization. These systems efficiently separate volatile and non-volatile organics and salts, enabling zero liquid discharge for difficult-to-treat wastewater.
The MVR technology integrates a stripping column to remove volatile organics and an MVR process to separate non-volatile organics and salts. This combined approach efficiently purifies water, allowing it to undergo further treatment to meet discharge standards or be recycled. This process ensures zero liquid discharge, making it ideal for complex wastewater streams.
