Water/Wastewater 39 TOC Analyses Difficult Industrial Water Samples
Expanding GE’s capabilities for process, environmental and wastewater analysis, the Sievers InnovOx On-Line Total Organic Carbon (TOC) Analyser will allow users to analyse challenging water samples on a routine basis without requiring excessive preventive maintenance. Monitoring the levels of TOC in the water is an important step for industrial users to control processes that are critical to their operations and to comply with regulations.
The Sievers InnovOx offers increased uptime and instrument reliability, two important features when it comes to analysing difficult industrial samples. It has been designed by GE Power & Water’s analytical instruments unit (
www.geinstruments.com) for the petrochemical, petroleum, pulp and paper and food and beverage markets, as well as environmental organisations and municipalities.
The InnovOx On-Line, like its InnovOx Laboratory model predecessor, uses an innovative Supercritical Water Oxidation (SCWO) technique that offers enhanced reliability, greater ease of use and lower maintenance than other TOC analysers available today. By utilising SCWO, the InnovOx is the TOC instrument most capable of cost effectively analysing difficult industrial process, environmental and wastewater samples on a routine basis.
SCWO has historically been used to treat large volumes of aqueous waste streams, sludges and contaminated soils. GE is the first company to use this technique in a commercially available TOC analyser.
The first commercial application for the new InnovOx On-Line TOC Analyser is monitoring seawater in Taiwan. The seawater, which contains about 3 percent sodium chloride, is used as industrial process water, and both incoming and outgoing water streams need to be monitored for environmental protection. One of the main sources of contamination can be hydrocarbons coming from a petrochemical refining process. The InnovOx’s robust handling of the brine sample was a significant factor in the analyser’s selection.
“The TOC market demanded technology with greater reliability and uptime, two critical needs that were not being met,” said Stephen Poirier, vice president of business development for the analytical instruments unit of GE Power & Water. “Our patent-pending InnovOx technology offers increased uptime and instrument reliability and handles tough samples easily.”
Submersible Oil-in-Water Probe Monitors Process and Waste Water
One drop of mineral oil can spill 1000 l of water. Even the slightest contamination by mineral oil in surface, process and industrial water can be detected by the new FP 360 sc immersion probe from HACH LANGE - reliably, continuously and uncomplicatedly.

Water Analysis Brochure for Water Quality Issues
Dionex (USA) is pleased to announce the release of its Water Analysis for a Global Market brochure (available in print, or as a downloadable PDF at
www.dionex.com/water). This brochure provides an overview of the issues surrounding water quality, global supply, contaminants, emerging concerns, ion analysis, and system solutions provided by Dionex.
Less than 1% of the planet’s water is available for human consumption. Resources for potable water are under increased demand due to population growth and global warming. With surface water contamination and groundwater resources overexploited, regulation and enforcement levels are increasing along with new regulatory and conservation policies. Coupled with the heightened scrutiny of emerging contaminants, the need for effective water analysis and monitoring has never been higher.
Water analysis requires good chromatography as well as an understanding of regulations. There are also the practical implications of water analysis which include workflow, cost, time, reducing complexity, reporting, system maintenance and upkeep, quality service, and many other factors.
As a leader in providing chromatography solutions for water analysis, Dionex understands the needs of providing the best solutions for water analysis. Dionex offers the most comprehensive capabilities for inorganic and organic contaminant extraction and analysis for drinking, ground, surface, and complex contaminated wastewaters.

FP 360 sc uses a highly sensitive ultraviolet fluorescence method for oil detection. Because most mineral oils contain polycyclic aromatic hydrocarbons (PAH) their concentration can be used to calculate the oil content of water. When PAH are exposed to ultraviolet radiation, they emit fluorescent light at an intensity which is directly related to their concentration. Measuring the intensity of this fluorescence is a much more sensitive method of determining PAH than measuring absorbance or scattered light.
Detection of Diesel fuel in waste water with FP 360 sc
The FP 360 sc immersion fluorometer is suspended directly in the measurement medium with the help of a chain mounting set. No time-consuming installation is needed. With the help of an optional flow cell, the probe can also be installed for bypass applications. The standard model is in stainless steel, and a titanium housing enables the probe to be used in aggressive media.
Quick detection of oil spills in process and waste water allows for taking fast countermeasures and huge savings in cleaning costs and possible fines. The FP 360 sc probe is used in combination with the proven SC controller. Extensive communication variants enable integration into existing BUS systems and into a network via Ethernet or in wireless form using GPRS for site-independent installation.
