STAR Control®

STAR Control®The unique tool for online controlof wastewater systems

STAR Control®Ranged STAR SystemsSTAR2 ProfessionalSTAR2 StandardThe STAR2 Professional is a unique online controlsystem. The advanced software is developed byKrüger and comprises years of experience and processknowledge.Since 1992, the STAR system has been installed successfullyin biological nutrient removal plants aroundthe world.The STAR system is a state-of-the-art control systemallowing the long-term process optimization of theconventional SCADA and PLC systems.STAR2Professional is an advanced online processcontrol system superior to the SCADA/PLC systems.STAR stands for: Superior Tuning And Reporting.The STAR2 family is the second generation of STAR Control® and is able tosupply the wastewater treatment plants with:⊲⊲⊲⊲⊲⊲An increased capacity – either biologically or hydraulicallyThe ability to meet the new and more stringent effluent requirementsThe capability to match the strict effluent requirementsSTAR is also an option if you consider:Wastewater treatment plantsoperating with STAR Control systems:⊲⊲Lynetten, DK, 750.000 PE (2008)⊲⊲Frederikssund, DK, 43.000 PE (2008)⊲⊲Linköping, SV, 161.000 PE (2007)⊲⊲Mosede, DK, 60.000 PE (2007)⊲⊲Kyungan, KOR, 48.000 PE (2007)⊲⊲Bruxelles Nord, BE, 1.100.000 PE (2007)⊲⊲Kolding, DK, 125.000 PE (2007)⊲⊲Jangdang, KOR, 25.000 PE (2006)⊲⊲Blois, FR, 103.000 PE (2006)⊲⊲Brande, DK, 13.000 PE (2005)⊲⊲Narva, EST, 70.000 PE (2004)⊲⊲Avedøre, DK, 365.000 PE (2004)⊲⊲Vedbæk, DK, 15.000 PE (2003)⊲⊲Varena, LIT, 20.000 PE (2003)⊲⊲Slagelse, DK, 85.000 PE (2003)⊲⊲Lundtofte, DK, 115.000 PE (2001)⊲⊲Hirtshals, DK, 53.000 PE (2001)⊲⊲Skagen, DK, 130.000 PE (2000)⊲⊲Bjergmarken (Roskilde), DK, 80.000 PE (1999)⊲⊲Stavnsholt, DK, 40.000 PE (1999/2004)⊲⊲Kujawy (Krakow), PL, 300.000 PE (1999)⊲⊲Poznan, PL, 900.000 PE (1999)⊲⊲Helsingør, DK, 72.000 PE (1999-2003)⊲⊲Frederikshavn, DK, 135.000 PE (1998/1999)⊲⊲Borås, S, 130.000 PE (1998)⊲⊲Harboøre, DK, 57.000 PE (1998)⊲⊲Søllerød, DK, (1998)⊲⊲Aalborg Øst, DK, 75.000 PE (1995)⊲⊲Sydkysten, DK, 23.000 PE (1994)⊲⊲Aalborg Vest, DK, 265.000 PE (1992)⊲⊲⊲⊲⊲⊲⊲⊲⊲⊲Reduced operating costs (optimized control)Flexible operation (adjusts to very high or very low loads)Equalization of fluctuations (industrial wastewater)High safety margin, stable and reliable operationImproved tools for operation and process managementMore ways to benefit from implementation of STAROne way to benefit from STAR is to optimize the operation of the existingwastewater treatment plant to achieve better performance and reduce theoperating costs significantly.STAR is also an option when you wish to increase the plant capacity, butpostpone or minimize the costs related to a possible extension of the plant.Ask for references of STAR Control® and STAR2 Professional.Online moduleSTAR-NSTAR-CSTAR-PSTAR-ATS% Reduction20-30% Effluent N10-20% Energy for aeration30-100% External carbon0-30% Effluent P30-50% Precipitation chemicalsLess sludge production50-100% higher flow (Alternating)25 % higher flow (Recirculation)Reduced volume of the reactors

STAR provides 24/7 assistance to the operatorSTAR is an excellent tool for improving and updating the process control of biologicalnutrient removal plants. STAR assists the operator by online adjustment of the controlset-points on the basis of online measurement of oxygen, ammonia, nitrate, phosphate,suspended solids etc. When the concentrations change in the plant, STAR will immediatelyreact and offer the optimum action on the basis of the settings made by theoperator.The continuous measurements which are the core of the STAR system are based onsamples taken ‘inside’ the process, i.e. where control actions will be most successful. Thecontrol actions are carried out immediately via set-points in the basic control system.The correct position of the online sensors ‘inside’ the process is very important in orderto achieve an easy, rapid and reliable control.The STAR utilize the very flexibleBiodenitro/Biodenipho systemsto the most efficint proces optimization.InfluentEffluentSystem DBIO-DENITRO® - DoubleBIO-DENIPHO® - DoubleA 2 /OA/O ®InfluentSettlingtankEffluentSTAR prform excelent optimizationof varios pre-denitifying and recirculatingplant designs.

The keyword “plant widecontrol” describes it all!Plant operation with STAR2 will result in reduced energyand chemical costs. An advantage of the STAR Control®is stabilisation and improvement of the effluent qualitythrough an optimization of the existing plant capacity.* e.g. combination of different process lines, advancedsecondary/tertiary operation of units, non-typical footprint/flow distribution etc.⊲⊲Return sludge control⊲⊲Flow distribution between plant sections on the basisof load variationsATS - AERATION TANK SETTLING⊲⊲⊲⊲Optimization of the hydraulic capacityStormwater controlAccess to STARinterface fromnetwork PCGraphic UserInterface for easynavigation to actualstate info, settingsand historic reportsInterface in locallanguage and Englishby standard⊲⊲⊲⊲Increase of the biological capacityRain gauge warning of high inlet flowIntegratedJournal keepstrack of importantchangesApril 2009Krüger A/SGladsaxevej 363DK-2860 SøborgTel: +45 39 69 02 22E-mail: kruger@kruger.dkwww.kruger.dkHaslegårdsvænget 18DK-8210 AarhusTel: +45 87 46 33 00Indkildevej 6 CDK-9210 Aalborg SØTel: +45 98 18 93 00Fabriksparken 35DK-2600 GlostrupTel: +45 43 30 01 11
