Hydrochloric ,acid, and ,sodium hydroxide, are metered into ,wastewater, mix tanks where the batches are blended and ,neutralized,. The tank fittings are located next to the side wall, and plant operators had ongoing problems with a different brand of ultrasonic level sensors due to their wide beam angle, and the resulting signal interference.

Neutralization
Neutralization

Neutralization, is a chemical reaction, also called a water forming reaction, in which an ,acid, and a base or alkali (soluble base) react and produce a salt and water(H 2 O). In other words, it ,can, be said that ,neutralization, is the combination of hydrogen ions H + and ,hydroxide, ions OH − (or oxide ions O 2−) to form water molecule H 2 O. In the process, a salt is formed.
