Water/Wastewater 49 Measuring Oil/Grease Levels in Wastewater
Determining total oil/grease levels to ensure compliance with governmental regulatory permit requirements for discharging wastewater is a worldwide problem facing all segments of the oil and gas industry. To ensure compliance with these regulations and avoid fines for exceeding permit discharge levels, more frequent wastewater measurements are necessary to determine the total oil/grease concentration. Wilks Enterprise (USA) manufactures portable infrared analyzers that are specifically designed for easy, on-site measurement of the oil/grease concentration and can be used by non- technical personnel.
Based on field-proven infrared technology, the InfraCal TOG/TPH Analyzers -- Model HATR-T2 or the Model CVH – depending on the solvent selected for the extraction process – provide accurate, on-site measurement of total oil/grease concentration in the wastewater. Typical analysis time is 10-15 minutes – including the extraction process. Measurement data obtained with the Model HATR-T2 correlates to EPA Method 1664 and with the Model CVH to ASTM Method D 7066-04 and EPA Methods 413.2 and 418.1.
Over 2,000 InfraCal TOG/TPH Analyzers are currently in worldwide use helping the oil and gas industry analyze produced water on off-shore and on- shore oil platforms, monitor refinery plant wastewater effluents, and measure discharge levels into treatment centers. They provide the assurance that oil/grease content of the wastewater will meet the various regulatory requirements.
Reader Reply Card no 172 Portable and Stationary Sampler
This special sampler in the DUO version is offered by the company QH SERVIS (Czech Republic) in both portable and stationary versions. The sampler contains two independent sampling units with a peristaltic pump enabling two mutually independent sampling modes. The sampler is suitable for sampling from two locations or from two different depths.
The device equipped with an easy-to-use control unit controlled from the external memory in the configuration connector (identical with Simply Sampler samplers), or Bond-oo-Check module with real time clock enabling logging of sampling data including sample temperature and connected analog signal value (identical with Soft Sampler samplers). Each sampling unit is standardly equipped with analog input for flowmeter signal, controlling the sample volume depending on the immediate flow, and digital inputs for remote control.

The need for pH electrode for particular applications is growing, as many users of pH Meters find the standard combination electrode supplied with their meter is not suitable for a particular application.
Sentek (UK) has successfully grown their business because not only do they offer a standard range of probes for various applications, but are prepared to make probes to suit a customers needs.
A good example of a probe which is successfully used for the measurement of beer, blood products, cosmetics, dairy products, paint, and micro samples is the P13. This has a 90 x 4.5mm dia stem, and is also available for NMR use in a 180 x 4mm stem. It has a range of 0-14 pH, with a temperature range of 0-80ºC. It has a ceramic frit junction.
