Case Study N°AA2 – Ambient air monitoring – WWP TRSMEDOR deodorisation – updated: 25.10.15 Case Study Ambient Air Monitoring Applications Waste water treatment plants Air quality control by TRS MEDOR Deodorisation 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. At the entrance of the waste water plants, where the waste water arrives, strongly smelling and polluted air is captured and neutralised by a chemical cleaning process called ‘’Stripping’’. The correct amount of chemical products needed to neutralise the polluted air has to be calculated. 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°AA2 – Ambient air monitoring – WWP TRSMEDOR deodorisation – updated: 25.10.15 TRS MEDOR system o At the point of arrival of the wastewater at the stripping area of the plant, the polluted air is captured and thereafter passed in a circuit that neutralises it. These odors are caused by bacteriological fermentation. Successive chemical cleanings in the deodorisation towers neutralize these odors. o The bad odors are largely due to the transformation of sulfides into H2S by the bacteria in the fermentation process. o Placed at the outlet of the stripping process, the TRS MEDOR...
