Aquionics specializes in the manufacture and distribution of medium pressure UV systems for both municipal drinking water and wastewater applications. By emitting UV over a wide range of the spectrum, the lamps damage a wide range of intracellular molecules, such as enzymes, in addition to DNA. This broad damage permanently inactivates the cells’ DNA repair mechanisms.

The new Eagle Model RP-1000 Chlorine Residual Analyzer provides the accuracy of amperometric measurement with the convenience and reduced maintenance of a probe-type device for reduced installation and maintenance costs and simplified system startup. The measuring element is an amperometric membrane probe that can be provided for measurement of either free or total chlorine residual. The instrument provides an isolated 4-20 mA output for remote indication, recording or data logging, and up to four user-configurable alarms. The probe is mounted in a flow-through assembly having an integral flow meter and valve for maintaining sample flow at an optimum rate.

With the introduction of the Rosemount Analytical Model FCLi, Emerson Process Management now offers pH-independent free chlorine measurement. With the new meter, the pH adjustment occurs inside the sensor, producing a reading that changes less than 5% per unit change in pH. The meter can measure free chlorine in water having pH as high as 10.0. The linear range of the sensor is 0 to 20 ppm (mg/L).

Chemical metering

Th 229726
Click here to enlarge image

Hydro Instruments’ V-RAD (Vacuum - Revolving Automatic Doser) is designed to meter low feed rates of liquid chemicals, such as sodium hypochlorite. The chemical is fed under vacuum, which eliminates all pressurized chemical lines. The chemical passes through a fixed-diameter orifice in shortly spaced intermittent pulses (allowing a larger orifice to be used). The dramatic pressure gradient across the orifice eliminates the concern of vapor locking. Most importantly, the feed direction through the orifice is reversed every 15 seconds. In this manner, the device is self-cleaning. The orifice is preceded by a “pocket”, which serves to carry any large solids around the orifice.
