Analyzer Helps Cut Treatment Chemical Costs, Reduce Power Consumption

Endress+Hauser has introduced the Liquiline System CA80AM ammonium analyzer for monitoring critical control points in water and resource reclamation facilities. The CA80AM analyzer 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 with ISO 7150-1, DIN 38406-5 and GB 7481-87 standards. The analyzer 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 analyzer to be integrated into any control system. The integrated web server allows a user to remotely analyze process disturbances and decide on required measures quickly, all through any web browser.

The Liquiline CA80AM and its sample preparation systems help plant managers keep their costs under control while optimizing their ammonia control strategies and complying with regulatory requirements. For example, using the analyzer for aeration basin control based on ammonia load allows for proper nutrient removal while reducing the amount of energy expended by running blowers unnecessarily.

The Endress+Hauser Liquiline System CA80AM ammonium analyzer monitors critical control points in water and resource reclamation facilities.

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 Liquiline CA80AM analyzer to guarantee synchronization of the measuring point. Endress+Hauser’s analyzer can have up to two channels of input to further reduce the cost of measurement across the water reclamation facility.

Ownership costs for colorimetric analyzers are highly dependent on the volume of reagents consumed and the reagent lifetime. The CA80AM has highly precise, positive displacement dispensers to minimize 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 analyzer’s electronics and does not require maintenance. Thanks to the very low rate of reagent consumption and cooling, reagents can last for up to 12 weeks.

Integrated automatic cleaning and calibration functions also ensure that the analyzer and its sample preparation work reliably and without manual intervention for extended periods of time. If an issue with the system arises, the analyzer’s advanced diagnostics and remote access quickly guide operations personnel to resolution.

The Liquiline electronics platform in the analyzer 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.

When installed in an aeration basin and combined with a suitable Memosens dissolved oxygen sensor, the CA80AM analyzer provides the required measurements for precise, load-dependent control of oxygen blowers with just one device, helping to substantially reduce energy costs.
