Wilks Enterprise has developed a portable infrared analyser that uses hexane to extract the oil and grease from effluent samples
The US Environmental Protection Agency (EPA) published a final rule on May 13, 2003 (68 FR 25685) for establishing limitation guidelines for discharges of "oily wastes" from facilities that produce, maintain or rebuild metal products and machinery (MP and M).
The rule became effective June, 12, 2003 and effects the following sectors "Aerospace, Aircraft, Bus and Truck, Electronic Equipment, Hardware, Household Equipment, Instruments, Mobile Industrial Equipment, Motor vehicles, Office Machines, Ordnance, Precious Metals and Jewelry, Railroad, Ships and Boats, Stationary Industrial Equipment, and Miscellaneous Metal Products".
These new limits on oil and grease concentration levels will force over 2400 industrial facilities to monitor their effluent more closely prior to discharge.
This means more frequent measurements to ensure compliance.
Wilks Enterprise has developed a unique portable infrared instrument, the InfracCal TOG/TPH Analyzer, Model HATR-T2, that uses hexane to extract the oil and grease from effluent samples.
In the new effluent limitation guidelines, the EPA lists oil and grease as "hexane extractable material".
Because hexane contains hydrocarbons, it must be evaporated off in order not to interfere with the infrared hydrocarbon measurement of oil and grease. Since the InfraCal TOG/TPH Analyzer measures the "hexane extractable material" and uses an evaporation process, it will closely match the EPA hexane/gravimetric method 1664.
With the Infracal TOG/TPH Analyzer, operators of pretreatment systems can quickly and easily assess their system's efficiency and can see how it functions under heavy loads.
They can also avoid discharging effluent that is above the regulatory limit.
