  • Page 39: Salinity Compensation

    SALINITY COMPENSATION If the sample contains significant concentration of salinity, the read out values must be corrected, taking into account the lower degree of oxygen solubility in this situation. Before taking any DO measurements remember to set the salinity value from the DO setup menu. The salinity affects the DO concentration, decreasing its value.

This quick measurement has many advantages: rapid measure of influent organic load and biodegradability, indication of the presence of toxic or inhibitory wastes, degree of stability and condition of a sample, and calculation of oxygen demand rates at various points in the aeration basin.
