Real-time phosphorus and ammonia monitoring in a wastewater treatment plant

A wastewater treatment plant in Estonia uses the HACH Phosphax sc phosphate analyser and HACH Amtax sc ammonia analyser for continuous online monitoring of phosphorus and ammonia concentrations.

In wastewater treatment processes, real-time nutrient monitoring is essential for maintaining stable treatment performance, optimizing chemical dosing, and ensuring compliance with environmental discharge requirements. Online analysers provide continuous process data without the delays associated with laboratory testing.

The installed system consists of two HACH online analysers designed for continuous water quality monitoring and process optimization.

HACH Phosphax sc Phosphate Analyser

The Phosphax sc analyser provides continuous orthophosphate measurement, supporting efficient phosphorus removal and process control. Key benefits:

  • Continuous real-time orthophosphate monitoring
  • Optimized chemical dosing for phosphorus removal
  • Faster response to process changes
  • Improved control of phosphorus elimination performance

HACH Amtax sc Ammonia Analyser

The Amtax sc analyser continuously monitors ammonia concentrations and supports biological wastewater treatment process control. Key benefits:

  • Continuous ammonia monitoring
  • Enhanced control of the nitrification process
  • Real-time visibility into biological treatment performance
  • Reduced risk of exceeding discharge permit limits

Results

Continuous online monitoring provides operators with real-time process visibility, enabling faster and more informed operational decisions. Key outcomes:

  • Improved process visibility and control
  • Optimized chemical consumption
  • More stable treatment performance
  • Faster response to operational changes
  • Greater confidence in meeting environmental compliance requirements
