Variability in discharge pH and the corrosive nature of strong mineral acids led to concerns over potential harm the discharge may cause to aquatic wildlife resident in estuaries. In addition to the plant needing to find a more environmentally friendly wastewater pH control solution, it needed to find one that would give it more robust control over the whole process.

What are the uses or applications of pH measurements?

A ,pH, meter is used to determine the ,acidity, or alkalinity of the solution. ,pH, is the concentration of hydrogen ions in the solution. A solution containing more H+ ions remains acidic while the solution containing more OH- ions remains alkaline. ,pH, value of solutions ranges from 1 to 14.

Why is pH important to agriculture?
Why is pH important to agriculture?

Soil ,pH, indicates the ,acidity, of your soil. A healthy, productive farm is created from the ground up. Soil ,pH, above 7 is alkaline and contains more negatively charged hydroxide ions. The soil ,pH, is an important number to know because it determines the availability of almost all essential plant nutrients.
