New System Enables Maintenance-Free Measurement of Organic Content


October 31, 2001, Greenwood, Indiana - Maintenance-free measurement of organic content is accomplished via proven ultraviolet technology with Endress+Hauser's newest addition to the StamoSens family of in-line evaluation systems.

The StamoSens CSM 750 transmitter and the CSS 70 sensor work in tandem to analyze the absorption of light at 254 nm. The absorption coefficient can relay information relevant to the TOC (Total Organic Carbon) concentration, the BOD (Biological Oxygen Demand) levels, and COD (Chemical Oxygen Demand). With StamoSens, treatment facility operators can monitor these elements around the clock, adjusting processes accordingly.

In wastewater operations, the organic load plays a crucial role, defining how to most effectively set up the plant to break down organic material. Therefore, accurate and reliable measurement of dissolved organic materials is essential for effective operation. For treatment plants with significant problems related
to organic loads, manual sampling is too slow to be effective. With the StamoSens system, operators are aware of the composition of the flow before it comes into the facility. Necessary adjustments can then be made, ensuring an effective process under constantly changing conditions.

In drinking water operations, the enhanced coagulation rule is based on the incoming carbon load. By monitoring the incoming TOC loads, the facility ensures compliance, while also optimizing their coagulant dosage.

The StamoSens product line also includes the CNM 750 transmitter and the CNS 70 sensor for in-line nitrate measurement. Unlike other systems on today's market, the StamoSens nitrate system requires no reagents, pumps, or rigorous maintenance procedures to effectively monitor and control nitrification and denitrification in wastewater operations.
