Nitrogen Oxides (NOx) monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

Oxides of Nitrogen (NO/NO2/NOX) is the product of endothermic reactions within combustion engines and causes significant environmental pollution. The main source of NOX is from the engine of automobiles and these pollutants are harmful to humans in their respective forms or in the creation of ozone (O3) or acid rain. NOX is most prevalent in our societies as a contributor to asthmatic conditions as well as the photochemical smog found throughout many industrialized cities.

Ozone monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

Ozone found in ambient air can have a direct affect on human health and also has the potential to create photochemical smog. It is for this reason that the U.S. EPA has set a one hour limit of 120 ppb and an 8 hour limit of 80 ppb. Ozone has been found to affect human health by harming the respiratory and immune system. People with pre-existing respiratory damage or diseases are more likely to suffer from the affects of ozone.

Ozone generators for laundry application

by Absolute Systems Inc.     based in Edmonton, ALBERTA (CANADA)

In recent years ozone laundry technology has proven itself to be an effective tool in helping to reduce water usage and energy consumption while also reducing wash and dry times, ensuring the absence of microorganisms, and improving the quality and useful life of laundered products. There are economic advantages to an ozone system as well as microbiological and environmental benefits. Currently in the United States there are over 2,000 ozone laundry systems in place and as many as 3,000 more in the United Kingdom alone.

Water quality monitoring systems for portable water plants

by SWAN Analytische Instrumente AG     based in Hinwil, SWITZERLAND

Low maintenance and reliability are key requirements for analyzers in potable water plants. Cost of ownership is another big issue.

Water quality monitoring systems for cooling water treatment industry

by SWAN Analytische Instrumente AG     based in Hinwil, SWITZERLAND

A number of treatment products are often added to prevent corrosion, scaling and fouling. Coating of sensors and other effects of these products must be taken into account when selecting analyzers. Discharge monitoring needs special attention because zero measurements must be reliable over time with little maintenance.

Water quality monitoring systems for high water purifier industry

by SWAN Analytische Instrumente AG     based in Hinwil, SWITZERLAND

The monitoring of “Ultra Pure Water” or “High Purity Water” requires the lowest possible detection limits for process analyzers. Resistivity is often around 18 MΩ. Dedicated instruments can detect infinitely small amounts (ppt e.g. parts per trillion) of ions.

Bromate analysis for the drinking water industry

by Metrohm AG     based in Herisau, SWITZERLAND

Bromate forms during the ozonization of drinking water. Several international standards stipulate detection limits and test methods. Conductivity detection with chemical suppression allows the determination of bromate in the lower μg/L range. In the ng/L range, bromate can be detected by IC/MS coupling or post-column derivatization with potassium iodide and subsequent UV detection.

Boiler Water Testing / Cooling Tower Water Testing

by Myron L Company     based in Carlsbad, CALIFORNIA (USA)

Boilers and cooling towers share two major water related problems: deposits and corrosion. As steam is generated by a boiler or water evaporating from a cooling tower, dissolved minerals are left behind, increasing the concentration of these minerals. Additional minerals are introduced via the water added to makeup the water lost to steam/evaporation. Eventually, the minerals reach a level (or cycle) of concentration that will cause either loss of efficiency due to scale or damage from corrosion. This level can be determined by the Ryznar or Langlier indices and correlated to a conductivity or TDS range. Most people recognize problems associated with corrosion. Effects from scale deposits, however, are equally important. For example, as little as 1/8` of scale can reduce the efficiency of a boiler by 18% or a cooling tower heat exchanger by 40%!

Cooling Water Treatment

by ProMinent Group - ProMinent GmbH     based in Heidelberg, GERMANY

Efficiency is everything in the cooling water circuit. Everything at ProMinent revolves around the perfect cooling water circuit, which needs to experience few losses over its long life. The precise metering of inhibitors and biocides and suitable filters make this possible.

Ozone/UV systems for Industrial, municipal, and residential wastewater treatment

by Lifetech     based in Brno, CZECH REPUBLIC

In 2004-2005 LIFETECH`s laboratory worked out an advanced oxidation process (AOP) for removal of dioxins and furans (PCDD/F), chlorophenols and other contaminants from the BCD process wastewater. Consequently, our technology was installed and from April 2006 successfully used in the `Spolana-Dioxins` Project at SPOLANA a.s. in Neratovice, Czech Republic, as a part of Special Wastewater Treatment Plant. Our supply consisted of an ozone generator with the output of 5 kg O3/h at 10% w/w ozone concentration, two reaction tanks with mixing systems, a vent ozone destructor, and a control system. The world largest project for removal of PCDD/F was managed by BCD CZ a.s., a subsidiary of Thermal and Chemical Soil Remediation Ltd.

Ambient Monitor Gas Calibration with Ozone Generators

by Environics, Inc.     based in Tolland, CONNECTICUT (USA)

Environics® Ambient Monitor Calibrator with Ozone Generators facilitate dynamic calibration of ambient air analyzers. These instruments automatically perform zero, precision, span and multi-point calibrations using NO, NO2, SO2, CO, O3, hydrocarbons and other gases of interest. All ozone generators are factory calibrated using a NIST traceable ozone standard. The Series 6100, Series 6103 and Series 9100 all meet or exceed U.S. Environmental Protection Agency requirements.

Utility Water Treatment

by ProMinent Group - ProMinent GmbH     based in Heidelberg, GERMANY

It makes economic sense to reuse process water. Why would you discharge water just because you've used it once? If this water is treated properly, it can be reused with ease, cutting costs in no time.

PTR-TOFMS systems for Flux Measurement of BVOCs

by Ionicon Analytik Ges.m.b.H.     based in Innsbruck, AUSTRIA

The ultra-fast analysis capabilities of IONICON PTR-TOF instruments are essential for eddy covariance flux measurements, allowing to study deposition and emission rates of biogenic volatile organic compounds (BVOCs).

Continuous emissions monitoring for chemical industry

by Opsis AB     based in Furulund, SWEDEN

Process control and emissions monitoring in a chemical plant is a challenge due to corrosive gases, high dust load, and high temperatures. To use an extractive system in this environment will demand a lot of maintenance.

Street-level monitoring

by Opsis AB     based in Furulund, SWEDEN

To measure the air quality in a city is a challenge. A large number of gaseous components need to be measured with high accuracy. The monitoring site needs to be representative for the city and the system has to be easy to maintain and calibrate.

Urban air quality monitoring

by Opsis AB     based in Furulund, SWEDEN

To measure air quality in the ambient air is a challenge. The monitoring site needs to be representative and not dependant on changes in local traffic. A large number of gaseous components need to be measured with high accuracy and high availability.
