Single-effect evaporator

The single effect evaporator is a fundamental thermal concentration system designed for treating challenging wastewater streams. Its configuration includes a heater, separator, condenser, forced circulation pump, discharge pump, condensate pump, and vacuum unit. Operating on a straightforward principle, it uses primary steam as the sole heat source, with the secondary steam produced during evaporation not being reused for further heating. This system offers exceptional flexibility and is particularly effective for small-scale applications involving high-salinity, high-COD, and other difficult-to-treat wastewaters requiring evaporation and crystallization. Key advantages include simple operation and control, lower initial investment, adaptability to varying feed compositions, and reliable performance with complex wastewater streams. Important technical parameters include evaporation capacity, steam consumption rate, heat transfer area, operating temperature and vacuum range, and final concentration achievable. As an ideal solution for batch processing, pilot testing, and specialized industrial applications, the single effect evaporation provides a practical and efficient method for volume reduction and contaminant separation where multi-stage systems may not be economically justified.
