deltafi tdeltafi tmade by systecAir-? ow regulation for sewage treatment plants- Precise- Compact- Maintenance-freeOptimisation of the oxygen concentrationEven very small changes of the sewage level in the aeration tank or of the aerator condition cause significant changes of the pressure conditions in the compressed-air pipings.The air diffusion of the plant is thus permanently exposed to partially strong variations. Therefore, the regulation of the aeration according to the oxygen concentration is too slow for a consumption-optimised regulation. The O2-concentra-tion responds to the actually delivered air quantity only with a delay. Therefore, the O2-concentration varies continuously around the setpoint value. This has negative effects on the power consumption and the cleaning process.deltafit, however, continuously monitors the delivery of air and thus responds immediately to the smallest hydraulic changes. Thereby, deltafit ensures a constant oxygen concen-tration and consequently an optimised process.The precise regulation of the air quantities for the aeration tanks ensures not only the optimum sewage treatment proc-ess: The exact measurement and dosing of the energy-in-tensively compressed air saves cash and prevents the costly production of „surplus“ compressed air which is not really required for the optimum operation of the aeration tanks.deltafit increases the efficiency of the installation through demand-driven air conduction. The compact measurement and control system saves energy costs and works maintenance-free over years, even under the harshest conditions. The optimally adjusted deltafit components are used in thousands and prove their high accuracy and availability in the entire process indus-try. After their installation and parameterisation, no expensive commissioning is required, according to the motto „Install - Switch on - Forget“.Saves costs and reduces CO2-outputEven medium-sized sewage treatment plants must partially spend electricity costs of more than 500,000 euros a year. Thereby, just making available the air supply for the aeration tanks often causes more than 60% of the total energy costs, i.e. more than 300,000 euros in the example mentioned. Therefore, the precise dosing of the air quantity is a decisive argument for optimising the operating costs. Often, an energy cost reduction of 20% or more can only be obtained through deltafit.Economic from installation to operationdeltafit saves energy costs over the whole investment period. deltafit is extremely cost-effective regarding the purchase. Pre-mounted and parameterised components ensure quick installation and simple commissioning. The intelligent drive provides not only the precise flap position; the integrated regulator and the transmitter power supply allow to do with-out an expensive, separate controller. The low pressure drop also saves energy costs. The high control quality and measur-ing accuracy of deltafit ensures optimum process operations, i.e. the optimisation of the decomposition performance and consequently the observation of the limit values during the process and, at the same time, prevents costly waste of com-pressed air. The maintenance efforts are practically non-exist-ent, the components used have a long life.??????????????????????????????????? ???????? ???????? ???????? ???????? ???????? ???????1FSJPE?PG???ZFBS"QQSPY??????QPTTJCMF?FOFSHZ?TBWJOHT?CZ?VTJOH?EFMUBGJU1PXFS?DPOTVNQUJPO?XJUIPVU?EFMUBGJUXJUI?EFMUBGJUTypical power consumption of a medium-sized biological sewage treat-ment plant.Measurement and regulation of air for aeration tanks???5JNF?3FHVMBUJPO ?0??DPOUSPMMFE"DUVBM?0??DPODFOUSBUJPO4FUQPJOU?WBMVF?GPS?UIF?0??DPODFOUSBUJPO.JOJNVN?0??DPODFOUSBUJPO???5JNF?8JUI?EFMUBGJU?SFHVMBUJPO ?BJS?RVBOUJUZ?DPOUSPMMFE3FRVJSFE?BJS?RVBOUJUZ 4FUQPJOU?WBMVF0QUJNJTFE?BJS?RVBOUJUZ0??DPODFOUSBUJPO"DUVBM?WBMVF?GSPN?EFMUBGMPX'MBQ3FHVMBUJPO1SPDFTT?DPOUSPM?TZTUFN??????EFMUBGJUBFSBUJPO?UBOLRegulation diagramVariation of the oxygen concentration2deltafitComponents Function Benefits1Measuring path • Compact construction • Built-in rectifier function, no inlet section required2Regulation drive Here, the air-quantity setpoint from the process control sys-tem is connected, and the flap position is regulated accord-ingly• Drive with integrated regulation • No additional wiring • Connect only setpoint and supply • High control quality • Easy parameterisation via Windows software • Various disturbance functions3Flap Regulates the flow • No dirt deposits • Robust • Cost-effective • Sensitive control characteristic4deltaflow + differential pressure transmitterMeasurement of actual flow value• Insensitive to dirt and condensates • Highly accurate *) • Integrates across the whole pipe section • No drift of measured value • Maintenance-free*) As an option, pressure and temperature can also be compensated.1234Construction and components3deltafi tThe delta? ow measuring principleRegulating precisely starts with the ac-curate mass fl ow measurement (actual value). The accurate and drift-free fl ow measurement is also a diffi cult measur-ing task in the practical operation of sewage treatment plants.• Optimum inlet conditions are not always possible.• The quality of the compressed air can be subject to humidity and contami-nation level and cause deposits in the fl ow sensors.deltafi t copes with all these problems: This air-fl ow measuring and control system uses the proven deltafl ow pitot tube. Its high accuracy was tested several times, even with reduced inlet sections, by the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig, Germany. The results are convincing: Even under restricted inlet conditions, the accuracy was always better than 0.6%.Particles, condensates, lubricating resi-dues are no problem for deltafi t: The deltafl ow has been approved by the TÜV according to 13 and 17 BlmSchV for contaminated, aggressive and condens-ing fl ue gases. Thereby, deltafi t uses a long-term accurate and absolutely ro-bust measuring method which minimises the maintenance and ensures the high control quality, even after many years. [The technical documents for deltafl ow are available at http://www.systec-controls. de/fi les/deltafl ow_prospekt.pdf.]The use of deltafi t is advantageous to the following applications:• Municipal sewage treatment plants• Industrial purifi cation plants• Large sewage treatment plants• Small wastewater treatment plants• Combustion air regulation e.g. steam boilers in waste incineration plantsProven a thousand times and simply reliableEven under unfavourable installation conditions, the deltafl ow pitot tube integrated in the deltafi t system can also accurately measure disturbed fl ow profi les thanks to the unique, patented probe profi le.The measuring path is designed in a way that disturbances of the fl ow profi le in the inlet are effectively reduced. This gives the devices a high accuracy, even under unfavourable inlet conditions. deltafi t works without expensive and susceptible slide valves. The fl ap used in place of slide valves works reliably, even with contaminated air, loaded with particles and condensate. „Flooding or drowning“ is not possible. The intelli-gent control drive of the fl ap takes over the power supply of the connected dif-ferential pressure transmitter. Therefore, no separate controller, which would need additional wiring, is required. Under normal operating conditions, the drive works free of maintenance. The reduction gears are lubricated for a life-time and require no relubrication.The deltafl ow pitot tube has proved its reliability for years in thousands of ap-plications, even under the harshest con-ditions. With almost a thousand applica-tions only in Germany, it is one of the best-proven methods for measuring gas fl ow. Approved as a fl ow measurement device for aggressive, contaminated and condensing gases according to 13 and 17 federal emission control ordinance, deltafl ow is ideally suited for the condi-tions in sewage treatment plants.Germany.
