  • In the chemical fertilizer industry, rare earth and many other chemical production processes, a certain amount of ammonium chloride wastewater will be produced. Because ammonium chloride content in ammonium chloride wastewater is higher and chloride ion exists, it will pollute the water if it is discharged directly. With emissions continue to grow, pollution levels are increasing.

    Multi effect evaporator has been widely used in this field. The evaporation process has high steam consumption, and the corrosion of the ammonium chloride solution to the material is very serious.

    MVR Evaporator as the most advanced technology can offer much better performance than multi effect evaporator is high saline waste water treatment. Considering about the corrosion of Chloride ion, Titanium alloy will be selected as the material touching parts.

    High ammonia nitrogen wastewater treatment basic process:

    1. After preheating, the waste water enters the heat exchanger, and then heated, evaporated and concentrated;
    2. The condensate water formed by steam flow back to condensate tank;
    3. The secondary steam and concentrated liquid flow into gas liquid separator; where achieve the liquid gas separation;
    4. Separated secondary steam goes for compressor. After compression, the temperature and pressure of the secondary steam increased and can be reused to heat the raw material.
