pH Neutralization in Wastewater Treatment | Sensorex

Most wastewater pH neutralization systems are well suited for submersion sensors from the top of the tank. Use couplers and plastic pipe attached to the top of the pH sensor to keep the cable out of contact with the solution and chemicals. 1. Support the sensor and pipe so it does not move around in the tank and impact the tank wall or mixer. 2.

18/3/2011, · If you do not need to treat for fluoride, you can neutralize the acid with caustic, instead. You will get much less sludge. Do a bench scale test first to determine the appropriate dilution factor, if any. If the acid is really strong it may heat up excessively during neutralization, causing the release of HF vapors, and possible damage to equipment.
