Power: A Multiparameter Instrumentation Approach to Makeup and Cycle Chemistry Measurements
|
From Mettler-Toledo Thornton Inc.
Process analytical instrumentation for both makeup water treatment and cycle chemistry measurements has evolved to meet the increasing demands of these major parts of the plant. Makeup treatment at many locations is faced with deteriorating quality of raw water supplies, increasing use of membrane processes and specifications requiring higher purity. Newer cycle chemistry treatment schemes depend on lower and more accurate cation conductivity, controlled dissolved oxygen and reliable pH, sometimes with reduced budgets for sample conditioning. There is heightened interest in the detrimental effects of organics in the cycle. Described here is the use of multiparameter instrumentation specifically designed to give successful measurements in these processes. Parameters of specific, cation and degassed cation conductivity, pH, dissolved oxygen, ORP and TOC as well as the benefits of having them available within a common instrument platform are discussed. Commonality of instrumentation for makeup water treatment and for cycle chemistry monitoring can greatly simplify specification, installation, training, operation, calibration, maintenance and spare parts inventory within the plant.
Products & Services
Deaerators are used to remove dissolved, corrosive gases from boiler feed water. They heat incoming makeup water for injection into the boiler, and return the condensate to a temperature which minimizes the solubility of these gases.
Dissolved oxygen sensors are used to measure the amount of oxygen dissolved in a unit volume of water. In water quality applications, such as aquaculture (including fish farming) and wastewater treatment, the amount of dissolved oxygen (DO) must be kept high.
Dissolved oxygen meters are analytical instruments that are used to measure the amount of oxygen dissolved in a liquid sample.
Water quality testing instruments are used to test water for chemical and biological agents, and to measure variables such as clarity and rate of movement.
Fixed growth treatment systems attach microorganisms to a surface that is exposed to water.
