The Series RPH-250 Analyzer, available from Hydro Instruments, makes use of the Amperometric method to determine residual levels in the sample water. The measurement is continuous, not relying on sample and hold methods, thereby allowing for better process control. The free-chlorine probe offers easily replaceable membrane caps. The analyzer is optionally available with pH compensation performed in software.

The MicroDynamicsTM microwave ultraviolet technology from Severn Trent Services uses microwaves to energize low-pressure, high-output lamps for municipal or industrial water and wastewater disinfection. With electrodeless lamps, there are no electrical connections to fail, corrode or leak. The lamps light instantly, providing immediate, reliable disinfection, and lamps can be switched on and off to match flow. The system offers a modular 4-lamp design to meet varying flow rates and demands, and the company’s standard three-year lamp life guarantee on each system reduces maintenance concerns and whole-life costs.

Analytical Technology (ATi) has introduced the Q45H/65 Residual Chlorine Dioxide Monitor for the online monitoring and control of disinfection systems. This system responds to chlorine dioxide with minimal interference from any residual chlorine that may be present. The monitor features a membrane-covered polarographic sensor that does not require the addition of chemical reagents. All that is needed is a consistent flow of water across the face of the sensor. That can be provided by a simple constant-head flowcell.

When higher chlorine feed rates require liquid withdrawal from containers for use with evaporators, it becomes extremely important to monitor and control the status of each valve on the container. Robo-Control® provides actuators to open and close the container valve. Digital indication of valve position and outputs for valve position are available. The actuator will communicate with an RTU or PLC for SCADA or in-plant control. Integral leak detectors provide immediate closure when a leak is detected.
