Key technology in industrial wastewater treatment for wastewater evaporators

     1. Evaporative crystallization technology:

Principle: By heating, the water in the wastewater evaporates, while impurities such as salt precipitate out in the form of crystals.

System composition: It primarily consists of a pretreatment system, a heating system, an evaporation system, and a crystallization system. The pretreatment system is responsible for removing large particles and suspended solids from the wastewater; the heating system heats the wastewater to boiling; the evaporation system evaporates the water content from the wastewater; and the crystallization system precipitates impurities such as salts.

     2.  Multi-effect evaporation technology:

Principle: By utilizing the difference in evaporation pressure at different temperatures and operating multiple evaporation units in series, heat energy is recycled, achieving the goal of energy conservation.

Advantages: High thermal energy utilization rate and low energy consumption.

     3.  Mechanical vapor recompression (MVR) technology:

Principle: The steam is compressed by a mechanical compressor to increase its temperature and pressure, and then reused in the evaporation process, achieving energy recycling.

Advantages: It further reduces energy consumption, enhances Wastewater treatment efficiency, and is more environmentally friendly.
