    Waste water treatment plants Air quality control by TRS MEDOR Online Odor Monitoring

    ontext & 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.

    Waste water treatment plants Air quality control by TRS MEDOR

    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.

    Water accountability portable monitoring for solving flow rate mystery

    The Glen Walter Sewage Collection System was built to service 1080 customers in 1989. At the time the population was 850 but by 1995 the sewage treatment plant had already reached capacity. Shawn Killoran took over the Operations Manger position in 1999 and, along with the Mayor and Council, he immediately had concerns about the excess flow.

    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.

    Wastewater treatment upgrades & extensions

    The time comes that a Sewage Treatment Facility Municipal or Industrial may require significant upgrading or even an extension. The upgrade usually concerns improvement process performance (removal rates) and efficiency as well as replacement of mechanical equipment. The plant expansion usually refers to an increase of the capacity or to the extension of treatment ability, ie adding Nutrient Removal.

    Treatment, Optimization and Design for WWTP's

    The purpose of the work is to demonstrate the rationale, procedures and advantages of using process simulation to evaluate the steps involved in process upgrades from conventional or fully aerobic process conditions to multi stage systems capable of operating as a BNR system. In the author's experience and the conclusions of this presentation are that the use of these systems in daily operations and in the preparation for process upgrading is empowering and economically advantageous.

    Measuring Fats, Oil and Grease (FOG) in Wastewater

    It is estimated that 23-28% of Sanitary Sewer Overflows (SSOs) are due to Fats, Oil and Grease (FOG). With significant growth in the commercial food sector on top of other high FOG producing industries such as metal processors, meat packers, cosmetic manufacturers and industrial laundry establishments, the need for publicly owned treatment plants (POTWs) and industries to regulate and monitor FOG is crucial to public health. Besides clogged sewer lines, high FOG levels also disrupt the effective operation of a wastewater treatment plant. An important feature of any FOG program is locating and monitoring high oil and grease producing industries and food service establishments. InfraCal TOG/TPH Analyzers provide a simplified procedure for FOG analysis based on solvent extraction and infrared absorption which can give the regulator or operator an on-site result in less than 10 minutes.

    Real-time Control System for Wastewater Treatment Plants

    Wastewater treatment plants (WWTP) are subject to large variation in flow and load, not to speak of uncertainties on the composition of the incoming wastewater. On top of that, the activated sludge treatment process, as used by the vast majority of treatment plants, is difficult to control due to the complex behaviour of the biological process. Nevertheless WWTPs are run 24/7, with operators and management challenged to meet ever tightening environmental regulations.

    In order to meet the operational demands of modern-day plants, a new control system was developed. Proprietary control algorithms were introduced based on a large set of data from nutrient measurements in various WWTPs. The customer`s benefits are twofold: (1) achieving optimum effuent quality and, at th same time, (2) lowering energy needs and dosing of commidity chemicals.
