A Better Way to Measure Dissolved Oxygen in Power Plant Pure Water Systems

measuring dissolved oxygen
In power plants, approximately half of unscheduled shutdowns can be traced to water cycle chemistry issues which involve costly repairs and lost operating revenue that can never be recovered. One of the most important parameters to measure to improve power plant water system efficiency is dissolved oxygen, DO. DO causes corrosion of components that contain iron and copper. Transport and deposits of these particles can also accelerate corrosion and damage critical plant equipment.

DO is measured at several locations in a water system. Traditionally, DO is measured with polarographic sensors, which use a gas permeable membrane to separate the sample from the electrochemical cell inside. Depending on the operating environment, polarographic sensors can require monthly electrolyte and membrane replacement.  After service, the sensor cannot produce meaningful readings for several hours because of required polarization. They are also sensitive to sample flow rate and experience interference from dissolved hydrogen.

Unlike traditional DO sensors, the Mettler Toledo Thornton online pure water optical DO sensor does not require polarization. It uses optical technology to provide fast and accurate analysis. Its measurement response is six times faster than polarographic sensors. The optical DO sensor also does not use electrolyte or a membrane, so it's not sensitive to flow or susceptible to damage from particles and dissolved hydrogen interference. There is no interior body to replace, and service is required only once a year to quickly and easily replace the one-piece Optocap sensing element. This provides plants with lower operating costs and reduced downtime. 

The Mettler Toledo Thornton pure water optical DO sensor provides a fast, accurate and low-maintenance method of measuring dissolved oxygen concentration in power plant pure water systems.

Continuous Total Organic Carbon (TOC) Monitoring vs. At-line Batch Method


At-line batch TOC measurement can only provide snapshots of your water quality every six minutes or more. But alot can happen in six minutes. With true continuous TOC analysis you have real-time data to tell you exactly when an excursion starts and ends. This helps demonstrate compliance and gives you complete control of your water system. The Mettler-Toledo 6000TOCi provides real-time TOC compliance.

Mettler Toledo Process Analytics Catalog 2018-2019

METTLER TOLEDO Process Analytics
The METTLER TOLEDO Process Analytics division concentrates on analytical measurement solutions for industrial manufacturing processes. The division consists of two business units: Ingold and Thornton, both recognized leaders in their respective markets and technologies.

Ingold is a worldwide leader in pH, dissolved oxygen, CO2, conductivity and turbidity solutions for process analytical measurement systems
in chemical, food & beverage, biotech- nology and pharmaceutical industries. Its core competence is high quality in-line measurement of these para- meters in demanding chemical process and hygienic and sterile applications.

Thornton is the leader in pure and ultrapure water monitoring instrumentation used in semiconductor, microelectronics, power generation, pharmaceutical, and biotech applications. Its core competence is the in-line measurement of conductivity, resistivity, TOC, bioburden, dissolved oxygen and ozone in determining and controlling water purity. The division recently expanded into Gas Analytics with a series of TDL analyzers offering unique in situ solutions.
