Components of a pH Adjustment / Neutralization System:
A basic pH adjustment / neutralization system consists of six basic components:
1. Instrumentation for monitoring, controlling, and recording
2. pH electrodes and/or ORP sensors and associated mounting hardware
3. Effluent holding tank
4. Level control
5. Chemical pumps and reagent storage tanks
6. Mixers/agitators
In this system, effluent flows into the holding tank where a pH sensor (also known as pH electrode or pH probe) senses the pH of the solution. The sensor provides input to the pH controller device which operates chemical pump(s) to inject acid or caustic as required to neutralize the effluent. The mixer serves to evenly distribute the neutralizing chemicals throughout the holding tank to ensure complete neutralization.
Choosing the best sensor for your needs is essential to proper system operation. Some basic parameters that are suggested:
Sealed combination sensors are best for submersion in-tank applications.
Double junction combination sensors will have a significantly longer lifetime than single junction sensors when measuring samples that contain heavy metals, sulfides, proteins, or other materials that interact with silver.
Automatic temperature compensation (ATC) is not typically required since there is very little temperature error at pH values close to 7, though using ATC can make setup much easier. If you choose to use a pH sensor without ATC, you must complete the temperature circuit on the terminal of the instrument with a resistor. For example if your instrument is looking for a 100 ohm RTD, a 110 ohm resistor across those temperature terminal will fix the instrument to 25⁰C.
