Proam Ammonia Monitor for Liquor measurement & control

The Proam ammonia monitor is manufactured in the UK by PPM and can be used for continuous measurement of activated sludge to control the nitrification process, optimise treatment and reduce energy consumption.

Proam Ammonia Monitor for Liquor measurement & control

The Proam ammonia monitor is a compact, simple and reliable analyser suitable for continuously measuring activated sludge and final effluent quality.


The instrument has been extensively installed throughout the water sector with many installations within Severn Trent Water, Wessex Water and Anglian Water. 

The Proam instrument is simple to operate and maintain. The design can be used for continuous or intermittent analysis and self- validates measurements against know calibration standards. 

The ion selective (gas sensing) measurement technique is ideal for waste-water applications and does not suffer cross interference from other dissolved ions in the sample. 

The dynamic measuring range can be simply adjusted within the range 0 to 500 mg/L as N (and to 15,000 mg/L by incorporating sample dilution). Typically the range is configured 0-100 mg/L as N for activated sludge applications but this is application and site specific. 

Whilst the instrument has pinch valve technology and wide bore tubing to minimise the possibility of internal blockage, PPM has also developed sample preparation and delivery systems to compliment the instrument. 

For the measurement of activated sludge, the membrane sample preparation can be mounted directly in to the basin and the filtrate is over-pumped to a sample header from which the analyser can continuous draw a sample for analysis. This approach provides a fast speed of response required for monitoring and control applications. 

The Proam can be mounted into a secondary enclosure suitable for hand rail mounting allowing the instrument to be installed directly beside the basin where analysis is required.
