1. Adjustments range for “Permeate Conductivity High” alarm is 0
- 50 S/cm for Rev D3 software; 0 - 200 S/cm for Rev EO or
higher software.
2. Below 200 S/cm, there are 2.5 units of specific conductance
(S/cm) per unit of TDS (ppm or mg/L CaCO3).
3. If an acid injection pump is installed, the high pH alarm
determines when the chemical pump turns on. Once the pH
rises to 0.8 units below the alarm setting, the pump turns on.
After the chemical pump lowers the pH to 1.8 units below the
alarm setting, the pump will be turned off.
4. Set alarm limit at 8 psi [6 (bar x 10)] greater than drop
observed during data collection for QA test form.
5. Set alarm limit at 1.5 x the drop observed during data collection
for QA test form.
6. Set alarm limit at 60% of flow observed during data collection
for QA test form.
