We thank you for your continued support of the Reading Room. The two primary corrosive agents in condensate systems are carbon dioxide and dissolved oxygen. The first of these, carbonic acid attack, is the topic of this week's technical tip. Oxygen pitting of the condensate system will be discussed in subsequent technical tips. The Accu4 system uses EPA approved GLI Method 2, ratiometric 4-beam measurement technique to provide highly accurate low level turbidity measurement.
Measurement is made using two near infrared LED's.
The four beam measurement technique automatically calculates out interference's such as process color and sample chamber fouling. A complete set of diagnostics is loaded into the analyzer, allowing for easy assessment of the instruments operational status. Verifying calibration is simple using GLI's patented Cal-Cube secondary calibration standard. This turbid glass cube is stable for years. The Accu4 system is ideal for use by water treatment facilities trying to meet the strenuous requirements of the Enhanced Surface Water Treatment Rule, individual filter and combined effluent regulations.
