Disinfection solutions for water treatment industry

by Calgon Carbon Corporation     based in Pittsburgh, PENNSYLVANIA (USA)

Ballast Water Solutions. Ship ballasts often carry aquatic organisms that can cause a significant problem when transported from one body of water to another. In fact, the invasion of non-native species via ballast water has been described by maritime and environmental authorities as `one of the greatest threats to the world`s waterways.`

Water intake protection monitoring for wastewater treatment industry

by Pollution & Process Monitoring Ltd     based in Sevenoaks, UNITED KINGDOM

Intake protection systems have been extensively installed to protect water treatment works, from ingress of polluted water and waste-water plants from toxic chemical loads. A suitable system typically comprises a suit of instrumentation, measuring key chemical, physical and indicator parameters dependant upon the identified risks, associated with the individual site activity or discharges from neighbouring industry.

Monitoring industrial trade discharge for wastewater treatement industry

by Pollution & Process Monitoring Ltd     based in Sevenoaks, UNITED KINGDOM

Industry has had to respond to the requirements of progressive environmental legislation such as the Urban Waste Water Directive, IPC, IPPC and now the EPR (Environmental Permitting Regulations). As successive legislation becomes more stringent, discharge consents have been progressively tightened, and the need for self-regulation has become more important. As a consequence, on-line instrumentation has been installed throughout waste-water industry to continuously to provide trade discharge monitoring and perform continuous water analysis for key consent parameters.

Water quality monitoring for semiconductor industry

by Real Tech Inc.     based in Whitby, ONTARIO (CANADA)

Water is fundamental to the manufacturing process in a semiconductor facility. Electronic components are rinsed or washed several times during the producing process with ultrapure water (UPW) to remove residue. Continuous monitoring of organic constituents (TOC) on the influent city water assist with UPW production. Good quality waste streams for the manufacturing process can also be monitored for reuse potential.

Water quality monitoring for dairy industry

by Real Tech Inc.     based in Whitby, ONTARIO (CANADA)

Continuous monitoring of process streams and waste streams in a dairy industry setting can provide various benefits to the operators. One major benefit is that it is possible to minimize product lost to the waste stream by means of reliable online monitoring of organics (TOC) at various points in the plant. In addition, due to the nitrogen deficient nature of milk wastes it is possible to optimize ammonia dosing by accurately and continuously monitoring the organic loads entering the waste stream.

Drinking water analysis for municipalities

by GE Analytical Instruments     based in Boulder, COLORADO (USA)

GE Analytical Instruments offers several Sievers TOC Analyzer models designed specifically to simplify monitoring of drinking water treatment plants. Always knowing the TOC levels throughout a water treatment plant, and improving TOC reduction, can help a plant not only control DBPs, but also implement efficient and potentially cost saving treatment processes.

Process Analytics - Water Purification (THORNTON)

by Mettler - Toledo Int. Inc     based in Greifensee, SWITZERLAND

THORNTON specializes in measurements for pure and ultrapure water treatment with parameters of resistivity, conductivity, total organic carbon (TOC), flow, pH, ORP, dissolved oxygen and ozone. THORNTON products are frequently used in semiconductor and microelectronics manufacturing, pharmaceutical and biotechnology processing, and power and steam generation, as well as food and beverage production.

Determination of TOC in stack

by Pollution Srl     based in Budrio, ITALY

PROBLEM: The industrial chimney's emissions of Volatile Organic Compounds (VOCs) are becoming issues of global importance and to have an accurate knowledge about how to test VOC turns into a strategic issue. VOC emissions are quantified and monitored according to standard EN 12619, using FID analyser which uses hydrogen and other reference gases in pressurized cylinder. Operators must then approach the sampling point, often placed several meters from the ground, climbing chimneys of industrial settlements with instruments and cylinders. Is it possible making this job easier and safer? SOLUTION: Using the Polaris FID analyser produced by Pollution Srl, Italy, it is possible to carry out the VOCs monitoring according to EN 12619 without lifting accessories and heavy weights typically involved with FID analyser. Polaris FID analyser complies with this standard regulation but what is really a breakthrough and cutting-edge, is the unmatched portability and the next generation technology

Drinking water solutions for the TOC removal efficiency

by Real Tech Inc.     based in Whitby, ONTARIO (CANADA)

Problem: Organic matter (UV254/TOC) in drinking water can react with chlorine to form harmful disinfection by-products (DBPs). Some removal of TOC is achieved through the conventional drinking water treatment processes, while carbon absorption may be used to further enhance the removal of TOC prior to chlorine disinfection.

Total sulfur measurement for sulfur compounds in CO2 for food & beverage industry

by MOCON - Baseline     based in Lyons, COLORADO (USA)

The BevAlert Model 8900 provides a total sulfur measurement for sulfur compounds in Carbon Dioxide. The measurement includes organic sulfides, Sulfur Dioxide, Carbonyl Sulfide, and Hydrogen Sulfide. The instrument is utilized by Specialty Gas Manufacturers and the Food and Beverage Industry to monitor sulfur compounds in CO2 used in carbonated beverages.

Analysis of VOC compounds in water by Purge & Trap or dynamic headspace

by Chromatotec Group     based in Val de Virvée, FRANCE

Context & Challenges Volatile organic compounds (VOC) can be dissolved in water. Sometimes water is polluted and to study contamination of VOC in finished drinking water, VOC must be measured. Chromatotec® Solutions Chromatotec® has developed a specific system for the measurement of VOC in water: a Purge & Trap system, the airmoPURGE. The analyzer is coupled with a degasing system allowing the extraction of dissolved gases. The complete system is based on: - 502.2 method from US EPA – “Volatile organic compounds in water by purge and trap capillary column gas chromatography with photoionization and electrolytic conductivity detectors in series – Revision 2.1”. - 524.2 method from US EPA – “Measurement of purgeable organic compounds in water by capillary column gas chromatography/mass spectrometry – Revision 4.0”.

Water monitoring for laboratories

by GE Healthcare UK Limited     based in Little Chalfont, UNITED KINGDOM

Chemical purity of water is assessed for a wide variety of different chemicals depending on the type of water and applicable local legislation. 

Chemical analysis of water can include testing for nitrogen compounds, dissolved heavy metals, and total and dissolved organic carbon.

Common water monitoring applications include:

  • Determination of suspended solids in waterusing for example glass fiber filters.
  • Chemical analyses of for example heavy metals, dissolved organic carbons (DOC), and ions.
  • Microbiological analyses using membrane based microfiltration methods

Monitoring surface water for wastewater treatment industry

by Pollution & Process Monitoring Ltd     based in Sevenoaks, UNITED KINGDOM

Pollution Risk: Surface water encompasses storm water derived from hard standing areas, river water and reservoirs. All types of surface water are at risk from ingress of pollution and therefore need to be monitored. On-line continuous monitoring can identify and alarm pollution so corrective action can be taken

Monitoring Raw Water Intake

by Turner Designs Hydrocarbon Instruments, Inc.     based in Fresno, CALIFORNIA (USA)

The Situation: Hydrocarbons in water intake used for municipal drinking water and desalination systems are commonly limited to 1 part per million. Problem: Naturally occurring organics in raw water are typically treated with chemicals. Total Organic Carbon (TOC) analyzers in the water treatment system can alert technicians when some type of organic material is present but cannot differentiate between natural organics, such as algae or leaves and hydrocarbons. Solution: A fluorescence monitor can be configured for sensitivity to hydrocarbons, with no significant response to other organics. The TD-4100XDC has the highest sensitivity to hydrocarbons in raw water, has a low cost of ownership, and can be modified with Teflon, Monel, and other corrosion resistant materials for sea water environments.
