16 Water/Wastewater A Revolution in On-Line Liquid Analysis


BioTector Analytical Systems Ltd. (Ireland) manufactures an innovative range of on-line liquid analysers, which apply a totally new approach to eliminating the many problems associated with on-line TOC, TN and TP measurement.


The BioTector is designed to analyse everything – from clean water to the most corrosive & polluted samples, with no filtering requirements. It’s patented oxidation method is what makes the BioTector unique. This oxidation process, known as Two Stage Advanced Oxidation (TSAO) is extremely aggressive and is therefore totally self-cleaning (Hydroxyl Radicals at an oxidation potential of 2.8 is only below fluorine). The reaction is unaffected by Chlorides (salts) up to 30% and the system can handle oils, fats and calcium up to 12.5%. Hence the BioTector is deemed to be the most reliable on-line liquid analyser on the market, with 6 month service intervals and <99.7% uptime with an accuracy of +/- 3%. It is designed so that there is no drift and therefore calibration is not required for the correct operation of the system.


The BioTector makes direct measurements without dilution in 6.5 minutes (TOC) and on a wide variety of ranges from 0-5mg c/l all the way up to 100,000mg c/l. Up to 86,000 samples per year can be successfully measured by the BioTector and the analysers can be calibrated to read TOC, TN, NO3, TKN, TP, COD, BOD, TC, TIC and VOC.


There are now over 500 BioTector units installed worldwide, many of which are operating in applications that would have been impossible with conventional technologies.

When it comes to industrial wastewater analysis, your testing materials must be tested as rigorously as the wastewater itself, and that’s exactly how we at Merck (Germany) designed our Spectroquant®


test kits. Many Spectroquant® analysis methods conform with


international standards and are thus comparable with references. All Spectroquant®


analysis methods are


validated. Validation data are registered for each single Spectroquant® document.


test kit and recorded in the validation


One of our greatest goals is to reduce the amounts of hazardous or toxic chemicals in our test kits. Some examples Nitrate test: the 2.6 dimethylphenol method is cadmium-free and non-carcinogenic; Lead test: chloroform-free extraction, and Anionic surfactants test: avoids direct exposure to chemicals due to pre-sealed, benzene-free extraction.


What’s more, Spectroquant® Cell test kits The characteristic feature of the Spectroquant® cell test kits is their high user-friendliness. Virtually all of the reagents necessary for the analysis are contained in cells. When you insert your cell into a Spectroquant® NOVA or Pharo photometer, the bar-


code on the cells make the instruments automatically select the correct method of analysis. Reagent test kits Spectroquant®


comes with comprehensive information on disposal and waste management issues. Reader Reply Card no 46


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.


Customised Telemetry Systems


reagent test kits contain highly stable, ready-to-use reagent mixtures. Selection of the appropriate cell format makes it easy to vary the measuring range as you require. We check the linearity of the calibration function for all cell formats. Each pack contains an AutoSelector that gives the bar-code for the selection of the correct method in the photometer. Spectroquant®


test kits can be used in conjunction with all spectrophotometers and also with photometers from other suppliers. Reader Reply Card no 47


Biofuels Producers – Ethanol and Biodiesel – Must Comply with Clean Water Act and Monitor Oil/Grease Discharge Levels


Both Ethanol and Biodiesel producers have been attracting the attention of the U.S. Environmental Protection Agency (EPA), as well as other government regulatory agencies, and coming under closer scrutiny to ensure their wastewater discharges comply with the Clean Water Act (CWA). Both Ethanol and Biodiesel plants have been fined for wastewater discharges exceeding established permit levels for oil/grease levels and polluting nearby streams and waterways. While Ethanol and Biodiesel plants are relatively new to the industrial community, they need to comply with operating permits and be able to respond to potential violations. This requires Biofuels Producers to monitor their waste byproducts more closely prior to discharging and measure oil/grease concentration levels to ensure compliance.


The portable, easy-to-use InfraCal TOG/TPH Analysers from Wilks (USA) are based on field- proven technology for oil/grease measurements. They enable on-site measurements in 10-15 minutes, eliminating the need to wait for off-site lab results. Measurement data obtained with the InfraCal Model HATR-T2 will correlate to EPA Method 1664 and with the InfraCal Model CVH to ASTM Method D 7066-04 and EPA Methods 413.2 and 418.1. With either InfraCal TOG/TPH Analyser, biofuels plant operators can quickly and easily measure the oil/grease concentration level of their waste byproducts and has assurance they are not discharging effluent that is above the regulatory limit.


The InfraCal TOG/TPH Analysers are the world-wide standard for measuring total oil/grease concentration levels in


water. They are widely used in the oil and gas marketplace on offshore oil platforms and refineries, as well as in numerous other industries for measuring fats, oil and grease concentration levels in wastewater.

Solinst (Canada) has a wide variety of telemetry options that you can customise to suit your remote water monitoring applications. With the addition of the RRL Gold Remote Radio Link, Solinst now has two unique systems, each with their own benefits.


STS Telemetry Systems are designed for larger networks or more remote locations, and use digital cellular, long- distance radio, landline or satellite communication. The RRL is ideal for localised, closed loop monitoring projects, and uses short-distance radio communication.


Both Systems work with the highly accurate and durable Levelogger series of dataloggers, and automatically send water level, temperature, rainfall, and conductivity data from the field to your office PC.


Whether you are monitoring water usage at a mine site or golf course, managing a watershed or municipal water supply, monitoring floods and stormwater, or supervising a landfill, using the Solinst Telemetry Selection Chart, you can identify the technology best suited for your application.
