BONCHEM CASE STUDIES
Our THERMOFLOW® PRODUCT has been used in the following case studies:
- Deep Mining Application (DIFFICULT CONDITIONS)
- Industrial Application (NORMAL CONDITIONS)
- Evaporator Application (EXTREME CONDITIONS)
- Boiler Application
Deep Mining Application
(DIFFICULT CONDITIONS)
This is when the water quality is poor, the service water is used as the make-up water and there are high levels of dust and mud contamination.
