WAUKESHA, WI. A new addition to the ChemScan^® Process Analyzer product line offers improved reliability and reduced operation and maintenance cost for automatic analysis of ammonia or phosphate in water. The ChemScan^® UV-2150 Process Analyzer, manufactured by Applied Spectrometry Associates, Inc. (ASA) in Waukesha, Wisconsin, is "targeted to compete with single parameter ion probes and colorimeters, but without the continuous maintenance and high monthly reagent costs that are typical for these other types of on-line analyzers," said Bernie Beemster, President of ASA.

"The typical UV-2150 owner should require no more than 5 hours per month of maintenance time and the consumable items used by the analyzer should cost no more that $10 per month for an automatic analysis of ammonia every five minutes," according to Beemster. "Phosphate analysis using a ChemScan^® UV-2150 will be less than $50 per month for most applications," he added.

The ChemScan^® UV-2150 Process Analyzer contains many of the features that are common to other ChemScan^® Process Analyzers including the use of multiple wavelength ultraviolet-visible light absorbance for analysis. "The use of multiple wavelengths for analysis makes it possible to eliminate sample conditioning steps and to simplify sample reagent additions that would otherwise be required," Beemster noted. "This is why operating and maintenance costs can be reduced to a fraction of the amount required for other products, without sacrificing accuracy or reliability," he added.

Although the ChemScan^® UV-2150 is limited to analysis of a single reagent assisted parameter such as ammonia or phosphate, the analyzer can monitor up to four sample lines and the analyzer is capable of having an individual detection range and data communication output calibration for each sample line. "One ChemScan^® UV-2150 analyzer can be used to monitor multiple points in a treatment process or monitor parallel flow paths at large facilities," said Beemster. "This capability eliminates the problem frequently encountered with fixed range analyzers, where one sample point has very high concentrations and has very small variations at the top end of the range, while another sample point has very small concentrations and all of the variation is at the low end of the range. Accuracy can be improved when each sample point can be individually calibrated over an appropriate range," he said.

Major applications for the ChemScan^® UV-2150 at water treatment plants include on-line analysis of free ammonia to control ammonia feed in chloramination processes and on-line analysis of phosphate products used for corrosion control.

Major wastewater applications for the ChemScan^® UV-2150 include on-line ammonia analysis for nitrification control or effluent monitoring and on-line phosphate analysis for control of chemical or biological phosphate removal processes.

Waukesha, WI. Applied Spectrometry Associates, Inc. (ASA) has been selected to provide ChemScan^® systems for automatic analysis of wastewater process chemistry by two major municipalities in North America.

The City of Orlando, Florida has ordered two ChemScan^® UV-6100 Process Analyzer systems for automatic chemical analysis at multiple sample points directly from the biological treatment process at the Conserv II Wastewater Treatment Facility. One system will detect nitrate, nitrite and ammonia at four separate sample points in the first stage of the treatment process. A second system will detect nitrate and nitrite at six sample points in the second stage of the treatment process. The complete system consists of the ChemScan^® analyzers plus sample control valves, filters, pumps and data communications and controls.

The City of Edmonton, Alberta, Canada has selected the ChemScan^® UV-4100 Process Analyzer System for analysis of ammonia, nitrate, phosphate, and UV light transmittance from the effluent of six biological nutrient removal process reactors at the Goldbar Wastewater Treatment Facility. The ChemScan^® System will also be used to estimate Chemical Oxygen Demand (COD) from one additional sample point at the primary influent to the process.

The Orlando and Edmonton projects have a combined value of "just over $225,000" according to Bernard J. Beemster, President of ASA.

"These projects are both outstanding examples of the ability of ChemScan^® technology to provide wastewater treatment facilities with an automatic stream of information describing significant chemical variables in their biological nutrient removal processes. This stream of information is available to monitor process trends and make operational adjustments to maintain compliance with treatment objectives, while minimizing the use of energy, chemicals and other resources," said Beemster.

"Prior to ChemScan, these facilities had to rely on a labor intensive program of manual sampling and laboratory analysis to obtain process chemistry information. By the time the laboratory results were available, several days may have passed and the process conditions being experienced by the plant may be significantly different than the conditions at the time the sample was obtained," Beemster noted. "Millions of gallons of wastewater may have passed through the plant during this time and any opportunity to improve treatment performance or minimize treatment cost will have been lost," he added.

"With ChemScan, Orlando will automatically receive a new chemical analysis at each sample point in their process every 30 minutes or less. Edmonton automatically will receive a new analysis of four parameters at each of six sample points once every hour. This information will be automatically communicated by the ChemScan^® system directly to the plant computer, which will permit the treatment process to be controlled automatically," Beemster stated.
