High ,pH, is often accompanied by high alkalinity. High ,pH, problems can be corrected by acid injection or in some cases by using an acid fertilizer. Rainwater in PA ,is acidic, (,pH 4,.0 to 5.0). Less commonly, low ,pH, (< 5.0) may result in toxic high levels of metals like iron and manganese; this is usually found in combination with low alkalinity.

4,) Why is MAP more acidifying than DAP? When added to soil MAP does not use up any H + ions in the soil solution, therefore, the full acidifying effect of the nitrification process impacts ,soil pH,. When DAP is added to a soil it reacts in a way that can allow for the phosphate ion to take up a H + ion, thus it has slightly less impact on ,pH, that MAP.

Chemicals used in ,wastewater, treatment to adjust ,pH, serve to modify the ionic charge of the ,wastewater,. A definition of ,pH, is an expression of the intensity of the basic or ,acidic, condition of ,wastewater,. Mathematically, ,pH, is the logarithm (base 10) of the reciprocal of the hydrogen ion activity. The ,pH, is expressed numerically ranging above 0 thru 14. A ,pH, or 7.0 is neutral and ,pH, below 7.0 ,is acidic, and ,pH, …

Example; ,pH, 6 is 10 times more ,acidic, than ,pH, 7 and ,pH 4, is 1,000 times more ,acidic, than 7. Alkalinity – Alkalinity is the ability of a solution to resist ,pH, changes when an acid is added. The acid molecules react with the alkalinity which results in the acid molecules being neutralized, therefor when adding acid to a solution with alkalinity, the ,pH, stays constant until the alkalinity is consumed.

The ,pH, controller has a preset ,pH, set point for the effluent and uses this measured value to determine whether the effluent is within compliance with that set point. If not, chemical pump(s) are operated to inject ,acidic, or caustic solutions as required to bring the effluent in the holding tank to the correct level.
