HIGH PURITY WATER
The monitoring of “Ultra Pure Water” or “High Purity Water” requires the lowest possible detection limits for process analyzers. Resistivity is often around 18 MΩ. Dedicated instruments can detect infinitely small amounts (ppt e.g. parts per trillion) of ions.
Chlorine, Ozone, ClO2
The pretreatment phase uses identical analyzers for Chlorine and Ozone as potable water plants. The measurement after dechlorination is more critical because the chlorine content must be zero.
AMI Trides is the best choice for such applications. The Trides sensor has virtually no drift. The absence of sample and the failure of sensor cleaning will trigger an alarm. Hence there are no false zeros. Samples must have a conductivity superior to 5 µSiemens.
AMI Codes is the right choice for samples with a conductivity below 5 µSiemens.
CHEMATEST portable photometer: A high precision portable photometer for chlorine, ozone and other disinfectants is available for calibration and QC.

STEAM & CONDENSATE IN FEEDWATER
The most important parameters in Water/Steam Cycles such as Cation conductivity, dissolved oxygen and pH are available as pre-assembled and factory tested units.
Dedicated analyzers for sodium, silica, phosphate and hydrazine are also factory tested and calibrated for immediate operation.

Conductivity in power cycles is measured directly (total or specific conductivity) and/or after a cation column (acid or cation conductivity). Additional, a third measurement after sample reboiling is available (degassed conductivity). SWAN has integrated the cation column into the instruments. This results in considerable less maintenance work.
Single Channel Monitors for specific (total) or acid (cation) conductivity.
Dual Channel Monitor for specific and acid conductivity with needle valve, cation column and flow meter. Additionally it is possible to determine sample pH and alkalizing reagent concentration, e.g. ammonia by differential conductivity .
Triple Channel Monitor for specific, acid and degassed conductivity with needle valve, cation column and flow meter. Additionally it is possible to determine sample pH and alkalizing reagent concentration, e.g. ammonia by differential conductivity .
Quality assurance: a portable instrument is available for quality control of on-line conductivity monitors.
