Analysis Method for pH and Alkalinity | Water Resources ...

When the ,pH, is above 7.0, the water is alkaline, or basic (there are more hydroxide ions than hydrogen ions). Since the scale is logarithmic, a drop in the ,pH, by 1.0 unit is a 10-fold increase in acidity. So, a water sample with a ,pH, of 5.0 is ten times as ,acidic, as one with a ,pH, of 6.0. ,pH, 4.0 is 100 times as ,acidic, as ,pH, …

Continuous Flow pH Neutralization Systems
Continuous Flow pH Neutralization Systems

Continuous Flow pH Neutralization Systems,. The HydroFlo ,continuous flow pH neutralization systems, are designed to neutralize the ,pH, of highly ,acidic, and highly alkaline process or waste streams, to a specific set point. They are designed to constantly process flow rates up to a maximum of 2,000 GPM. HydroFlo systems are completely automated, ...

pH Adjusters for Water Treatment | pH & Alkalinity | ChemREADY

A ,pH, adjuster is a chemical used to alter the ,pH, or Potential Hydrogen level. ,pH, (Potential Hydrogen) is the measurement of the activity of the hydrogen ion or how basic or ,acidic, something is. By adding a ,pH, reagent such as an acid you can drive ,pH, downward. By using a caustic or other alkaline substance you can drive ,pH, upward.
