Case Study N°AA4 – Ambient air monitoring – WWP TRS MEDOR Stripping – updated: 14.10.15 Case Study Ambient Air Monitoring Applications Waste water treatment plants Screening area: stripping 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. To ensure the safety of operatives in the screening building/area of waste water treatment works an H2S analyzer has been installed in the main building to complement the protection provided by individual monitors. Chromatographic measurements show that other sulfurous compounds including Methylmercaptans are present in the air in addition to H2S. Five outlets in the building are located near six rough screens dedicated to primary treatment. The presence of sulfur compounds can vary from screen to screen and from one day to the next depending upon the quality of the incoming waters. Measurements need to be taken as close to the incoming water as possible. Results for each area are visually presented near the entry/exist 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. sales@chromatotec.com www.chromatotec.com

Case Study N°AA4 – Ambient air monitoring – WWP TRS MEDOR Stripping – updated: 14.10.15 Map of Waste Water Site TRS MEDOR system 1. Sampling: the analyser has a multiplexer that allows for the six inlets. The maximum length between the analyser and the sampling point is 10 meters. The atmosphere around the screens is quite humid and incoming lines are setup to stop humidity reaching the analyzer. Analysers at the STRIPPING STRIPPING STRIPPING 2. Analyzer: is capable of measuring H2S and mercaptans in ambient air. Compounds like IPM, TBM, NPM, MES, 2BM and NBM are optional. The measuring...
