Our company uses the multi-effect energy-saving principles and technologies, combined with the membrane pre-treatment in the earlier step and the drying in the later step, to build the integrated processing equipment of evaporation, concentration, and solidification. The company has the core technology with independent intellectual property rights. We can also provide different treatment methods depending on the characteristics of the wastewater.

Principle：

◆ The MVR mechanical vapor recompression equipment uses the secondary steam generated in the evaporation system to perform
work through the compressor, increasing the steam pressure and enthalpy, circulating for heating and evaporation, having full use of the residual heat of the secondary steam and condensate in the system, and saving energy efficiently. In addition to using fresh steam during starting of the machine and steam for preheating raw materials, no extra steam is necessary. The evaporator can be self- circulated to achieve the purpose of evaporation and concentration, which can save 70 ~ 90% of energy consumption.

Features：
◆ Easy operation; high level of automation; small floor space required; low energy consumption.
◆ Automatic liquid level control system; automatic feeding and condensate draining system.
◆ Equipped with a separating device to increase the crystal content of the discharged material. After the separation process is completed, most of the crystals can be obtained (optional drying and packaging systems can be installed if necessary). The mother liquor only has little reflux (which can be directly evaporated). Optional Roots compressor or centrifugal compressor can be equipped as well.
◆ The forced circulation evaporator is used to take the advantages of large heat transfer coefficient and large evaporation intensity. The materials will be less likely to accumulate on the walls or block the pipes. It is especially suitable for materials that generate crystals during the evaporation process.
◆ The self-pumping circulation system is used to keep the crystal and mother liquid circulating at all times to avoid the crystals blocking the pipes.
◆ Our company combines technologies such as multi-effect evaporation and MVR to save energy consumption, along with membrane for pre-treatment and drying for post-treatment, to make the comprehensive integrated system of pre-treatment, evaporation, concentration and drying possible. Our company has the core technology with independent intellectual property rights, and we can also use different evaporation methods for different wastewater treatment.
