Field of application
Phosphorus is the decisive factor for excessive algae and plant growth in water bodies, that's why continuous monitoring of this parameter is essential. The Liquiline System TP analyzer offers precise online measurement of total phosphorus and ensures highest process safety. Automatic calibration and cleaning save you operating costs while advanced diagnostics with remote access support you in providing process documentation to the authorities.
The Liquiline System TP analyzer monitors:
Inlet and outlet of wastewater treatment plants for documentation purposes and calculation of the cleaning capacity
Discharges of industrial wastewater treatment plants to determine discharge fees and to support the polluter-pays-principle
Process water
Benefits
Molybdenum blue method according to EN ISO 6878:2004 guarantees direct comparability to laboratory results
Meeting industry needs: The analyzer is perfectly suited for environmental monitoring, industrial and municipal wastewater
Fast and easy process integration: Direct installation of self-priming version or y-strainer for bypass applications
Safety on the highest level: Software-controlled safety cover for the reactor and all heated parts. Additional safety light barrier prevents overdosing of reagents and sample.
Combination of reliable sample delivery and high-precision dosing: Peristaltic pumps are able to cope with particles in the sample. Light barriers enable precise, reproducible dosing.
