pH Monitored
TREATMENT SOLUTION pH NEUTRALIZATION SYSTEM – TIME BASED
A non-monitored, time based, volumetric type injection system is provided
to automatically meter user supplied neutralization agent into the sump, to
neutralize highly acidic or alkaline solutions to a neutral pH before discharge
to drain to conform to plumbing code requirements.
TREATMENT SOLUTION pH NEUTRALIZATION SYSTEM – MONITORED
A monitored, proportional type system to automatically inject user supplied
neutralization agent into the sump to neutralize highly acidic or alkaline
solutions to a neutral pH before discharge to drain to conform to plumbing
code requirements. The treatment solution pH is sensed with a probe and a
neutralizing agent is injected to achieve a neutral pH.
USER CONTROLS
the range for the discharge of solutions may be adjustable from 0.0 – 14.0
using the following controls: “pH High” which sets the upper limit for
discharge to drain, and “pH Low” which sets the lower limit for discharge to
drain.
Figure 7–12. pH MONITORED
MAINTENANCE REQUIRED
Every six (6) months, calibrate pH transmitter and probe.
To calibrate the pH transmitter and probe:
1. “pH CAL” adjustment is made with a buffer solution of 7 pH. Adjust the
“CAL” potentiometer until the display reads 7.00.
2. “SLOPE” adjustment is made with a buffer solution of 4 pH. Adjust
“SLOPE” for a reading of 4.00. Continue to adjust each potentiometer
alternately using the specified buffer solution until no adjustment is
required.
