    Section 2 General Information 2.1 Safety information Please read this entire manual before unpacking, setting up or operating this equipment. Pay attention to all danger and caution statements. Failure to do so could result in serious injury to the operator or damage to the equipment. Make sure that the protection provided by this equipment is not impaired, do not use or install this equipment in any manner other than that specified in this manual.
  • Page 10: Product Overview

    Note: The flow-through units of the high precision NITRATAX plus sc and the NITRATAX clear sc sensors are used wherever direct measurement in the medium is not possible for structural reasons, or the medium load makes it necessary to measure a filtered sample (very high TS content, sewage treatment plant inlet, waste dump leachate, etc.).
  • Page 11: Theory Of Operation

    General Information 2.3 Theory of operation Nitrate dissolved in water absorbs UV light with wavelengths below 250 nm. This inherent absorption by nitrate makes it possible to photometrically determine the nitrate concentration without reagents by using a sensor positioned directly in the medium. As the measuring principle (Figure 3) is based on the evaluation of (invisible) UV light, the color...

    Operation 5.6.1 Adjusting turbidity compensation 1. Take a sample of activated sludge at the measuring location after the first half of the aeration phase. Immediately after sampling approximately 100 mL, filter the sample using a folded filter. 2. Similar to a standard solution, pour the filtrate into the measuring path of the sensor. As an alternative, the measured value can also be determined by a laboratory measurement (for NO N and NO...
