Our <br />environmental division manufactures pH neutralization systems, pH adjustment systems, Acid Wastes <br />Neutralization (AWN) systems, heavy metal reduction systems, fluoride reduction systems and many other <br />turnkey systems to treat industrial waste water effluent streams. This site is dedicated primarily to pH <br />Neutralization / pH Adjustment Systems. <br />pH Adjustment Systems for Industry <br />Of all the parameters that aze monitored and controlled in industrial effluents, pH is the most common, There <br />aze, of course, many other controlled parameters such as heavy metals, TSS, cyanide and toxic anionic species <br />such as Fluorides. pH, however, ranks as the most commonly controlled pazameter. Due to the nature of the <br />pH titration curve of water the range that most effluent waters are limited, 6.0 < pH < 9.0, is a very tight band. <br />As a result of this titration curve, using water in an industrial process will often result in a pH that is outside of <br />this band. <br />Digital Analysis Corp. manufactures pH Adjustment / pH Neutralization systems for any application and any <br />flow. We have systems as small as 300 gallons per day and as large as 72 million gallons per day. We service <br />industries ranging from Metal Plating /Finishing, to Pharmaceutical, Chemical Processing, Semi-Conductor, <br />and many more. <br />[You will note that we have used pH Neutralization / pH Adjustment together. Actually the two terms are <br />synonymous and we prefer to use pH adjustment only. The term pH Neutralization implies adjusting the <br />pH to a neutral pH, which is a pH of 7.0. Since this is impractical to do in most cases, and given the fact <br />that all industrial discharges are provided range, such as 6.0 < pH < 9.0, we prefer to use the term pH <br />Adjustment. Using pH Adjustment as opposed to pH neutralization, we avoid the implication that the <br />discharge will always occur at a true neutral pH of 7.0] <br />http://www.phadjustment.com/index.htm 9/9/04 <br />
