Wastewater, with a high pH is generally neutralized with sulfuric ,acid, (H 2 SO 4), hydrochloric ,acid, (HCl), or carbon dioxide (CO 2). The most common chemicals used are H 2 SO 4 and NaOH. ,Neutralization, can be accomplished by batch treatment or continuous flow processes. Batch treatment is usually for lower flow volumes.

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.

Principle,: ,Alkalinity, measures the ,acid,-neutralizing capacity of a water sample. The ,alkalinity, in a water sample measured by the amount of standard ,acid, needed to lower the pH. Based on stoichiometry of the reaction and number of moles of Sulphuric ,acid, needed to reach the end point, the concentration of ,alkalinity, in water is calculated.
