Online silica monitoring for demineralisation, boiler feedwater and water–steam systems.
Silica measurement is part of the water-quality picture in high-purity systems. The 3S analyser follows changing concentrations at a defined sample point, helping operators review treatment performance and investigate departures from normal operation.
Agree the required silica fraction and reporting basis as SiO2. The soluble-silica method is not automatically a total-silica measurement, so reference sampling and preparation need to match.
Monitor treated water and investigate changes in plant performance.
Review the silica trend alongside the other measurements specified for the water–steam cycle.
Select the analytical range and sample arrangements around the concentrations that matter to your process.
Soluble silica reacts with molybdate before a reduction step develops a blue colour. The optical reading relates that colour to the silica concentration in the sample.
The 3S-CL runs batch analyses at a programmable frequency. Automatic calibration, validation and cleaning can be scheduled, and the analyser separates its wet section from the electronics.
Agree the required range, cycle time and plant outputs when specifying the instrument. The manufacturer documentation gives the options and installation requirements for the selected configuration.
Send PMA the sample source, expected concentrations and available laboratory results. Include temperature, pressure, solids and any constituents that may affect the analysis.
We will review sample delivery, filtration or dilution where needed, drainage, reagent storage and service access. Include the required signals and alarm response so the measurement can be used by your operating team.
PMA helps you bring the analyser, sample system and site requirements together. Talk to our team about selection, commissioning, reagent supply and support for your installation.
The published method is for soluble silica. If your requirement includes particulate or total silica, discuss suitable sample preparation and reference methods with PMA before selecting the system.
Speak to the PMA team about your instruments, reagents or service requirements. Tell us what you need, and we’ll help you find the right next step.
