10/4/2021, · The ,wastewater, would then be passed through an air-,stripping, tower to transfer the ammonia to the atmosphere. Average initial conditions for alkalinity and ,pH, in the ,wastewater, were expected to be about 0.5 meq/L and 6.0, respectively. In the preliminary design plan, four options for increasing the ,pH, were considered: 1.

The ,acid, 8 used for reducing the ,pH, of the ,wastewater, can be any available suitable ,acid, such as hydrochloric ,acid, or sulfuric ,acid,. A suitable ,acid, is not SO 2 or SO 2 dissolved in water. Thus, as used herein, the term ",acid," when referring to an ,acid, added to ,wastewater, as part of the SO 2 disinfection process excludes SO 2 gas and SO 2 dissolved in water.

Thus, alkalinity and acidity cannot be determined by the addition of an ,acid, or base until a ,pH, change occurs, because the first drop will always result in some change. Instead, samples are commonly titrated to a pre-determined ,pH,. By convention, the ,pH, is usually about 4.5 …

As the maximum precipitation ,pH, for all these metals is not the same, we look for the optimum ,pH, zone. Sometimes, two ,pH, adjustments and two floc separation stages will be required. One favourable case is the preponderant presence of a metal (at least 5 times more concentrated as mole/mole) which, as it precipitates, "drags" the others to its optimum precipitation ,pH, .
