APPLICATIONWith growing public awareness and concern for controlling water pollution and enactment of the Clean Water Actin 1972 (amended in 1977) it has become increasingly important to continuously monitor the quantity of effluentsin waste water prior to discharge. Finding a method of accurately obtaining results in a cost effective manner hasplagued industrial companies for years due to the nature of the chemistry involved.The development of photometric and spectroscopic techniques has proved an invaluable tool in the applicationof on-line effluents monitoring. The removal of hazardous solutions and high temperature applications coupledwith fast response and high accuracy has brought the use of photometric correlation techniques to the forefrontof waste and process water monitoring.COMPARISON OF ORGANIC MEASUREMENT METHODSParameters254 nm UVFlourescenceExtraction withIR AbsorptionStripping with FIDResponse Time< 15 sec.> 5 min.> 5 min.Detection of TotalHydrocarbonsNo(only aromatics)YesYesFilteringInstallation TimeNoneMinutesRequired forWaste WaterHoursRequired forWaste WaterHoursMaintenance &OperationEasyHardHardAnalyzer CostLowHighHighChemical UsageNoneYesNoneGas UsageNoneNoneYes
OPERATING PRINCIPLEThe W-800’s measurement cycle is based a UV light source reacting with the oils to cause fluorescence which isthen detected and measured.The sample is constantly flowing through a quartz cell (a peristaltic pump option is available for non-pressurizedsample to provide flow).The operating principal quantifies the concentration of oil based on the fluorescence intensity measured by aphoto-multiplier tube located perpendicular to the UV light path. An auto-zero feature allows the analyzer to adjustfor turbidity, slow fouling or deterioration of light sources by resetting the baseline of the full light intensity. Thefinal concentration calculation is correlated to the florescence intensity of the sample based on a programmablecorrelation chart, which can be customized by the end-user.To further enhance the overall performance of the system, multi-band options are available to give the analyzer abroad measurement range.The W-800 UV Oil in Water Analyzer can be used to monitor multiple streams via external stream switching.Sample test results may be sent to any one of four (4) locations by switching the output Stream Setting(corresponding with the four (4) signal relays at the back of unit).DIMENSIONSinch (mm)9.500 (241)2.000(51)CUSTOMER CONNECTIONS1-45.000(127)2.000(51)POWER IN13.25(337) 8.000(203)2.000(51)SAMPLE RETURN18.250(464)24.500(622)22.000(559)20.250(514)18.750(476)17.000(432)2.000(51)4.250(108)SAMPLE INLET13.50(343)CALIBRATION SAMPLEIN4.250(108)15.500(394)
