Characteristics of the Condensed Water
- CODcr 10,000~15,000 PPM, NH₃-N 500~1,500 PPM​
- Contains a high concentration of organic solvents, VOCs, and ammonia​

Chemical treatment (Pre-treatment)​
- Removal of SS, oil, heavy metals (simple coagulation precipitation)
- Control pH for the evaporator efficiency

Evaporative concentration​
- Removal of most of pollutants except VOC, low boiling point substance
- The general operating pH zone is alkali, then the condensed water contains high concentrations of ammonia.

STRIP SYSTEM
- COD removal rate is 40~60%
- T-N removal rate is 90%

Biological treatment
- Removal of residual COD and T-N through nitrification and denitrification
- ​For reducing the space, we recommend MBR or TUBULAR System

Chemical treatment (Post-treatment)
- Removal of residual COD and T-N by AOP treatment
