Measuring alkalinity is important in determining a stream’s ability ,to neutralize acidic, pollution from rainfall or ,wastewater,. It’s one of the best measures of the sensitivity of the stream to acid inputs. Alkalinity in streams is influenced by rocks and soils, salts, certain plant activities, and certain industrial ,wastewater, discharges.

Neutralize, the pH and Dilute the Solution. The pH of all spent caustics should be raised or lowered to bring the substance back to a neutral state. Once this state is achieved, dilute the solution substantially. It’s important to note that even after spent caustics are neutralized and diluted, they are still not suitable for dumping in waterways.

Because some of the reaction products are acids, a base such as lime or sodium hydroxide is generally used ,to neutralize, the ,acidic, products, hence, the generic description of the process as neutralization. The base may also catalyze the hydrolysis to permit it to be carried out more rapidly and with more efficient use of process equipment.

At a COD loading rate of 3 to 7kg/m 3 ·d) a COD removal of almost 90% could be achieved. Because of the high COD removal rate of the anaerobic stage, nitrification occurred in the first post-,treatment, plant but only to nitrite due to high ammonia concentration and high pH. In the second activated sludge plant stable nitrification was obtained.
