For Total Recovery of Process Dragout |
Rinse water and dragout counterflow through several rinses to the process tank. The excess water is removed from the process solution by the EVAPORATIVE TANK™. Heat for evaporation is taken from the process. A level control and solenoid valve can control the water flow into Rinse 3. This level control and air lift pump are available from Poly Products Corporation. |
| An alternative heating method if evaporation rates are limited by low temperature processes. rinse water and dragout are collected in the new heated tank; concentrated dragout is returned to the process tank as needed. (The new tank can also concentrate process solutionfor added room in the process tank.) | Total Recovery, Cold Process |
| A very high recovery percentage can be achieved with little evaporation. This diagram illustrates the tank layout for economical, partial recovery. |
