Description:
This chapter provides an overview of applicability, amenability, and operating parameter ranges for various inorganic parameters:this chapter will also provide a compilation of existing and new online technologies for determining inorganic compounds in water samples. A wide variety of online technologies are used to measure the inorganic parameters discussed in this chapter. The general types of monitors used to analyze inorganic parameters are summarized in Table 6.1. The term "analytical sensor" or "sensor" used in this chapter refers interchangeably to a combination of a sensing/measuring device and an electronic analyzer. The analyzer is an electronic device that performs the computations and typically includes a signital display and a remote signal transmitter. There may be other laboratory or non-commercial analytical methods available for measurement of these parameters in grab sample mode that are not included in this document.
This information presented here for online inorganic monitoring was researched from a number of sources, including vendors of analytical instruments, US EPA, AWWA, the Instrumentation Testing Association (ITA) and other relevant web sites. Many of the analytical methods upon which the identified technologies are based are included in Standard Methods (1998), a reference that is widely used in the water and wastewater industries. At the time of publication of this chapter, the authors were not able to find information describing online monitoring devices for the many inorganic metallic and nonmetallic constituents of interest to drinking water utilities for which discrete sample methods are included in Standard Methods (1998). However, technology is developing at an incredible rate and the reader should keep in mind the possibility that sensors or monitors could be dsigned and available at any time after this book is published.
