WTEYA uses MVR evaporation technology to provide a complete zero-discharge solution for coal chemical wastewater

06 Jun, 2025 11:08am

 

Coal chemical wastewater is one of the most complex and difficult to treat types of industrial wastewater. It contains a large amount of refractory organic matter, a high concentration of salt, and toxic pollutants, which not only pose a major threat to the environment but also face increasingly stringent emission regulations. With the continuous improvement of national environmental protection standards, achieving near-zero wastewater discharge (ZLD) has become a key goal of coal chemical enterprises.

 

WTEYA Group is standing at the forefront of this green transformation. With its advanced MVR (mechanical vapor recompression) evaporation technology, it provides a complete, efficient, sustainable, and integrated zero-emission solution for coal chemical wastewater treatment, helping enterprises achieve green development and environmental compliance.

Why choose MVR evaporation technology?

 

MVR evaporation technology compresses the secondary steam generated during the evaporation of wastewater and recycles its heat energy, effectively reducing energy consumption while highly concentrating pollutants in the wastewater. This technology is particularly suitable for the treatment of high-salt, high-COD coal chemical wastewater.

 

Core advantages:

 

✔️ High water recovery rate: Recover up to 95–99% of clean water to achieve resource reuse

 

✔️ Energy saving and consumption reduction: Recycle heat energy to significantly reduce operating costs

 

✔️ Efficient pollutant removal: Concentrate salts and organic matter into controllable solid waste

 

✔️ Stable and reliable operation: Designed for industrial continuous operation and easy maintenance

 

 

✅ WTEYA's ZLD system solutions include:

 

✔️ Pretreatment system: removes suspended solids and provides stable water quality for the evaporation system

 

✔️ MVR evaporation unit: modular design, customizable according to different water volumes and water quality

 

✔️ Crystallization system: achieves salt separation and reduction treatment

 

✔️ Intelligent automation system: supports real-time monitoring and remote management, improves operating efficiency and safety

 

Through multi-technology collaboration, a closed-loop water treatment system is formed to effectively support wastewater reuse and environmental protection standards.

 

 

✅ MVR evaporation technology is applied to zero discharge of coal chemical wastewater, which can achieve the following effects:

 

Reduce wastewater discharge: The MVR evaporator can concentrate wastewater and significantly reduce wastewater discharge. If the "nanofiltration salt separation + MVR + crystallizer" process is adopted, high-salt wastewater can be concentrated to a solid content of 20%-40%, achieving wastewater reduction.

 

Resource recycling: The useful components in the concentrate can be recycled, such as inorganic salts and organic solvents in wastewater for the production of other chemical products. It can also recycle resources such as salt and heavy metals in wastewater to promote the circular economy model of "wastewater as resources".
