  7. Clarity II Turbidimeter • Clarity II Turbidimeter product position: • Design supports accurate low-NTU for DW plants • Key regulatory measurement for DW plants

  8. Turbidity Definition - What is it? Turbidity is the “optical property that causes light to be scattered and absorbed rather than transmitted in straight lines through the sample.” Ref: Standard Methods for Examination of Water and Wastewater Turbidity is the clarity of the water sample.

  9. Light Scattered by Particles Light Source Transmitted Light Scattered Light at 90° Detector Turbidity Theory - Basic Nephelometer Turbidity is the measure of the amount of light scattered by particles in a sample. A beam of light passes through a sample containing suspended particles. The particles interact with the light and scatter the light. A detector at 90° measures the intensity of the scattered light.

  13. Wet Chemistry Analyzers

  14. phosphate and silica turbogenerator superheated steam boiler condenser deaerater cooling water makeup water feedwater heater train silica hydrazine and sodium Where is the WetChemused?

  15. Where is the WetChemused? turbogenerator supercritical steam exhaust steam deaerater steam generator condenser cooling water makeup water shell and tube heater condensate polisher hydrazine sodium silica

  16. Where is the WetChemused? IP steam HP steam Steam turbine Deaerater HRSG Generator Exhaust gas HP IP LP Condenser silica Generator Demineralizer Gas turbine Hotwell HRSG HP: phosphate and silica IP and LP: phosphate hydrazine DI water tank

  17. Raw water Purified water Demineralizer Why measure silica? Conductivity measures how well ionic contaminants are being removed. Contains mostly ionized dissolved solids, like sodium chloride. Also contains silica, which is not ionized. Silica analyzer measures how well silica is being removed.

  18. steam to turbine turbine steam drum steam generator silica vaporizes boiler water Silica drops out of the steam and plates out on the turbine blades. silica accumulates in the boiler Why measure silica (cont’d)?

  19. boiler turbogenerator superheated steam condenser deaerater cooling water Phosphate in the boiler water controls pH and reduces corrosion. Acid forming contaminants from cooling water leakage accumulate in the boiler. Why measure phosphate?

  20. Why measure sodium? turbogenerator supercritical steam exhaust steam deaerater steam generator cooling water condensate polisher condenser The polisher blocks corrosive contaminants.

  21. WetChem • Colorimetric analyzers • Silica • Phosphate • Hydrazine • ISE (ion specific electrode analyzer) • Sodium

  22. LED detector capture sample add reagents wait for complete color formation measure absorbance How does the Colorimetric Analyzer work?

  23. CALIBRATION CURVE standard sample absorbance blank hydrazine, ppb ppb = abs sample – abs blank slope How is the WetChem calibrated? BLANK STANDARD

  24. ISE (Sodium) Analyzer pH glass electrode mV is proportional to -log ([H+] + a[Na+]) Typically, a is small, so unless [Na+] is very large, there is no error. Na glass electrode mV is proportional to -log ([Na+] + b[H+]) For the electrode to respond properly to sodium, the H+ concentration must be low enough, i.e. pH high enough, for the second term to be negligible.

  25. How is the ISE (Sodium) Analyzer Calibrated? • Analyzer response is directly proportional to log Na. • Standardization is a two point calibration using 10 ppb and 100 ppb standards. mV 100 ppb 10 ppb log Na

  26. What is the WetChem Analyzer? electronics colorimeter valve pump drain mixing chamber overflow sampler stream selector for multiple sample input cartridge filter in sample reagents and standards
