Describe the purpose of AIC-301 blow down system.


What will be an ideal response?


AIC-301 has a set point of 30 PPM. This variable is carefully controlled. As the cooling water flows from the tower to the operating units and back to the cooling tower it picks up suspended materials. The blow down system releases a specific quantity of dirty water that is replaced by fresh water. Concentration cycles in CTW-302 typically can range from 3 to 7. The cooling tower is typically set at 6 concentration cycles before it blows down the system. A cycle describes one pass from the cooling tower to the process and back to the cooling tower. Cycles of concentration display the accumulation of dissolved minerals in the recirculation system.
