Water/Wastewater
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.

Rapid Detection of Organic Pollutants Reader Reply Card no 78
How does Merck help me keep food and water safe? Easy!
Our broad range of test materials are straightforward and intuitive to use – and they deliver reliable,
rapid results every time. That’s good news for the way we live.
That’s what’s in it for you. Merck Chemicals
Naturally occurring and human-influenced pollution incidents often lead to an increase in harmful levels of organic material in surface and ground waters. This creates a significant threat to potable water quality as well as to the equipment used in treatment plants dependant on these sources. AstraGuard rapidly and continuously measures the UV absorbance of water and gives an instant indication of organic pollution, much faster than other methods, such as TOC and COD, which were primarily developed for laboratory analyses. With no moving parts and a sealed optical system AstraGuard from AstraNet (UK) requires little maintenance and has been proven as an intake protection device at many locations in the UK.
Along with organics AstraGuard can monitor colour and turbidity as well, enabling waste and effluent to be checked for discharge compliance. Enhanced sensitivity is offered by the long path-length flow cell that is linked to the instrument by fibre-optic cables; enabling flexibility in location and ease of access to all parts of the system. Stand alone logging or automatic control through SCADA/PLC systems is supported.

The Spectroquant® Pharo 100 and Spectroquant® Pharo 300 spectrophotometers are programmed to work seamlessly with over 150 Spectroquant® test kits in water and food analysis.
New Water Data Logger Manages Readings from any Location
STS (Switzerland’s) newly developed watermanager solution allows for conveniently managing and reading data loggers from any location at any time. In case of an out-of-limits condition, a warning message is generated and transmitted automatically via SMS and e-mail. In this way, a maximum degree of flexibility and cost efficiency is attained with regard to the monitoring of water levels and temperatures of rivers, lakes, ground water, sources, and boreholes.

The WEB watermanager software offers a clear overview
of all data loggers. It enables the configuration and monitoring of measuring data. Data may be downloaded directly into the customised analysis software or an Excel spreadsheet.

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.
oceanographic instrumentation.
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.
