New ammonium analyser from Endress+Hauser for wastewater applications

Endress+Hauser introduces the Liquiline System CA80AM ammonium analyser for monitoring critical control points in water and resource reclamation facilities.

The CA80AM analyser and its sample preparation systems provide an automated approach to process control and regulatory compliance.

To keep discharges at permitted levels and to avoid penalties, managers of water treatment and other resource recovery facilities need accurate and reliable measurements in their nutrient monitoring systems.

The Liquiline CA80AM colorimetric analyzer provides these measurements by using the standard indophenol blue method, which is compliant to ISO 7150-1, DIN 38406-5, and GB 7481-87 standards.

It also provides data storage and retrieval using on-board logbooks to allow continuous documentation for reporting to regulatory agencies.

Multiple communications methods — including EtherNet/IP, Modbus, Ethernet, and an integrated web server — allow the analyser to be integrated into any control system.

The integrated web server allows users to remotely analyse process disturbances and decide on required measures quickly through a regular web browser.

The Liquiline CA80AM and its sample preparation systems help plant managers keep their costs under control while optimising their ammonia control strategies and complying with regulatory requirements.

For example, using the analyser for aeration basin control based on ammonia load allows for proper nutrient removal, while reducing the amount of energy expended by running blowers unnecessarily, Endress+Hauser says.

Three sample preparation systems offer various filtering methods based on the characteristics of the sample, and include automatic backwash systems to keep the filters clean.

All sample preparations are digitally controlled by the analyser to guarantee synchronisation of the measuring point.

A CA80AM can have up to two channels of input to further reduce the cost of measurement across the water reclamation facility.

Its positive displacement dispensers minimise the amount of reagent used for analysis and it can be fitted with a smart, energy-efficient Peltier cooling module for the primary reagent.

The cooler is controlled automatically via the analyser’s electronics and does not require maintenance.

Integrated automatic cleaning and calibration functions ensure the analyser and its sample preparation work reliably and without manual intervention for extended periods of time.

If an issue with the system arises, the analyser’s advanced diagnostics and remote access quickly guide operations personnel to resolution.

The Liquiline electronics platform in the analyser allows for the creation of a complete measuring system by connecting up to four analytical sensors via the digital Memosens protocol.

Memosens sensors from Endress+Hauser include dissolved oxygen, total suspended solids, chlorine, pH, and ORP.
