AV410 single-channel UV254 low-level dissolved organics monitors (0 to 20 mg-1C) are designed for use on potable water treatment plants. In particular, they can be used to monitor the quality of the outlet from sand and carbon filters to provide a THM precursor measurement.
Long term field trials have shown that maintenance demands on these applications are minimal.
The dual-channel AV411 dissolved organics monitor is designed for use on potable water treatment plants. In particular, it can be used to monitor the quality of the outlet from sand and carbon filters to provide a THM precursor measurement.
The dual-channel AV412 dissolved organics monitor conveniently combines the high- and low-range measurements so that both the before and after coagulation or filter samples can be monitored.
The single-channel dissolved organics monitor AV420 is designed for use as a surrogate color monitor on coagulation control applications, and provides early warning of increase in organics from decay of algae blooms for potable water treatment works.
The dual-channel dissolved organics monitor AV422 is designed for use as a surrogate color monitor on coagulation control applications, and provides early warning of increase in organics from decay of algae blooms for potable water treatment works.
The AV450 nitrate monitor has been designed for use on potable water treatment plants as a means of determining the quality of the final treated water. Other applications include blending of high and low nitrate waters and for borehole waters.
The AV455 nitrate monitor has been designed for use on potable water treatment plants as a means of determining the quality of the final treated water. Other applications include blending of high and low nitrate waters and for borehole waters.
The AW100 has been developed as a simple device to monitor the quality of water from softeners. Applications include laundries, utility boiler plants, soft drinks factories, brewing,
food processing and potable water plants. It provides an alarm for high hardness that starts an automatic regeneration of the ion exchange beds used most commonly in these applications.
The AW100 uses one of four reagents that changes from green to red at a predetermined water hardness level. The reagent is added to a known volume of sample via a small pump until a color change takes place. The volume of reagent required to bring about this reaction (monitored photoelectrically) indicates the level of hardness of the water sample. The AW100 also provides an analog signal, the range of which is determined by the choice of one of the four reagents available.
The digital display on the front of the monitor and the analog output show the value of the last analysis cycle. Three alarm outputs are provided – two concentration alarms for control purposes and one alarm to drive an audible signal device. There are also inputs for a flow device and suspension of the flow cycle.
The AW401 design enables connection of up to 3 residual chlorine monitoring sensors to the system or enables pH, ORP and residual chlorine sensors to be combined, thus reducing the cost of each measurement considerably
