Case Study WWTP application-online odor monitoring - 1

Case Study N°AA3 – Ambient air monitoring – WWP TRS MEDOR odor monitoring – updated: 25.10.15 Case Study Ambient Air Monitoring Applications Waste water treatment plants Air quality control by TRS MEDOR Online Odor Monitoring Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. Odors are very distinct air contaminants as they generate nuisances. The factors playing a role in the determination of odor annoyance are: odor concentration and intensity, frequency, appreciation, duration, synergy and location. CHROMATOTEC® proposes an automatic solution to well identify the origin and the level of odors. Chromatotec® Solutions TRS MEDOR ppb or ppm for up to 14 compounds With only one instrument, it is possible to analyse up to 14 sulfur compounds. Thanks to specific sulfur detector (SSD) and AIR or N2 carrier gas, the separation and sensitivity is excellent down to 1 ppb levels and low odor unit/m 3. The instruments are being calibrated with primary gas standard certified at ±2%. There are no interferences due to the gas chromatography separation and the sulfur specific detector. The analyzer is LINEAR: range 0 / 100 ppb. The instruments are fully automated thanks to internal calibration (airmoCAL). The VISTACHROM software controls the analyzers, multiplexer, meteorological station and enables storage and display of the chromatograms thanks to Peak Viewer. It is possible to transfer data to a data logger or modelling software with the communication protocols MODBUS RTU, JBUS, German PROTOCOL and X-Path. A comprehensive solution for odor monitoring, including: - Data Acquisition and transmissions - GPRS/ModBUS/4-20 mA/0-1 V - Internal auto calibration to validate automatically the data sales@chromatotec.com www.chromatotec.com

Case Study WWTP application-online odor monitoring - 2

Case Study N°AA3 – Ambient air monitoring – WWP TRS MEDOR odor monitoring – updated: 25.10.15 It is possible to monitor specific WWTP odors at emission and at environment. The specification allow to identify origins of the odor (odor calculation based on odor threshold determined by scientist). Option: Data Reporting and modeling Software o Real Time Odor Dispersion Modeling o Online Registration of Complains o Recalculation of Odor o Concentration at Specific Location & Time Multi stream: (2 to 12 streams control by analyzer) Meteorological Station: wind direction and speed, temperature,...
