Table 4. Standards for processes
| Process | Requirement |
|---|---|
| Heat rejection and cooling | No once-through cooling with potable water for any equipment or appliances that reject heat. |
| Cooling towers and evaporative condensers | Equip with all the following: • Makeup water meters • Conductivity controllers and overflow alarms • Efficient drift eliminators that reduce drift to max of 0.001% of recirculated water volume for counterflow towers and 0.002% of recirculated water flow for cross-flow towers |
| Discharge water temperature tempering | Where local requirements limit the discharge temperature of fluids into drainage system, use a tempering device that runs water only when the equipment discharges hot water. |
