Swan Analytical USA Inc. is a leading manufacturer of, and field service provider for, online analytical instruments for measuring turbidity, free chlorine, total chlorine, chloramines, bromine, ozone, pH/REDOX, dissolved oxygen, phosphate, fluoride, ammonium, nitrate, and conductivity/TDS in drinking water production.
Based in Wheeling Illinois, and with field sales offices throughout the US, Swan is the US subsidiary of Swan Analytical Instruments AG in Switzerland. For more than 30 years Swan has been a technology leader in online analytical instrumentation that is not only of the highest quality, precision and reliability, but also having the lowest long term cost of ownership due to the low or no maintenance needs of the instrumentation. The Swan group of companies employ many of the world’s recognized expert chemists, engineers and technicians in the field of on-line water quality analyzers for drinking water, electrical power generation, semiconductor, pharmaceutical and food and beverage applications. As a privately held company, Swan continues to be able to take the long view when it comes to product development and support, customer relationships, and employee development.
SWAN Analytical USA is a leading manufacturer of high quality on-line analytical instruments for water analysis in applications such as high purtiy water, steam, condensate, cooling water, potable water and effluent. SWAN instruments measure a number of parameters within these applications such as turbidity, chlorine, sodium, dissolved oxygen, pH, ORP and others. Built with Swiss precision, SWAN's reliable analyzers are designed with the operator in mind.

Swan Analytical provided trusted online analyzers across a broad range of industries for key water quality parameters. Founded in Switzerland in 1991, Swan now brings Swiss quality and innovation to satisfied customers worldwide.
Monitoring raw water turbidity is important to inform the operator of significant changes in water quality, especially turbidity, allowing the operator to make process chemistry changes to respond to the increasing raw water turbidity. Variations in raw water present turbidity measurement challenges different from those found elsewhere in a typical treatment plant.
The SWAN DIST series Distribution Quality Monitor line offers three options for measuring chlorine, pH, conductivity and turbidity on one easy to install, easy to maintain panel. Versatile output options ensure water quality throughout your distribution system, proving piece of mind and customer satisfaction.
When Flint Michigan discontinued purchasing water from the Detroit Water Authority and began using the Flint River as their raw water source they unfortunately did not consider the potential impact on lead and copper corrosion and the impact on the public.
For the Village of Lombard’s Water Division, consistently delivering high-quality tap water to the community’s nearly 44,000 residents and the businesses serving them was once quite a juggling act: constantly fixing old, temperamental analyzers; feeding reagents into the old analyzers; and staying ahead of callers complaining about “musty” water tastes and odors. Not today.
Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.
The City of Gordon Texas’s drinking water facility was struck by lightning. Thinking long term, and desiring the latest technology available, the City took this opportunity to upgrade their on-line instrumentation with a range of new continuous monitoring on-line instruments including chlorine analyzers, pH monitoring, temperature monitoring, and turbidity monitoring.
Continuous analyzers are an integral part of the process to maintain quality, ensure compliance, and protect public health. Therefore it is imperative to ensure the analyzers are functioning properly and provide accurate and reliable data. This requires validation of the data provided by the analyzer on a routine basis. In addition some continuous analyzers incorporate internal data validation capabilities to inform the end user the reliability of the data provided by the analyzer. This paper discusses integrated data validation and how they may be integrated into SCADA systems.
Russellville water treatment plant is a surface water plant using traditional clarification, filtration, and treatment. The plant historically has used traditional contact turbidimeters that employ tungsten lamps that required quarterly maintenance, but replaced their turbidimeters with Swan Turbiwell turbidimeters in 2012. Read the full report for a comparison of the performance of the Swan Turbiwell to the previously installed turbidimeters.
This report gives a brief outline of the general measuring methods. Further, it illustrates the possibilities and limitations of the direct UV oxidation, as well as which technical modifications were made to the monitoring instrument, AMI Line TOC, to improve the performance of the UV reactor and, therefore, the precision of the instrument.
