    UV fluorescence technology for raw water intake monitoring industry

    Naturally occurring organics in raw water are typically removed with chemicals. Total Organic Carbon (TOC) analyzers in the water treatment system can alert technicians when generic organic material is present but cannot differentiate between natural organics, such as algae or decomposed plant matter, and hydrocarbons. Using UV fluorescence technology, a properly configured TD-4100XD can alert operators to upsets caused by hydrocarbons such as gasoline, diesel, fuel oil, and crude oil.

    Monitoring Hydroelectric Dam Sumps

    The TD-4100XD, with its UV fluorescence technology and non-contact flow cell, has very strong advantages over any other oil in water monitor for this application.

    Monitoring of hydrocarbons in bilge water

    Various processes onboard ships, such as machinery wash-down, maintenance, and leakage, generate oily wastewater. This contaminated water flow collects in the bilge of the ship. Marine diesel, lubricating oils, grease, as well as other contaminants may be present in bilge water. The bilge water is discharged overboard, with oil and grease concentrations in the discharged water limited by national and international regulations.

    Monitoring oil in power plant cooling water

    The TD-4100 utilizes a non-fouling, non-contact flow cell which requires little to no maintenance, and uses fluorescence technology to accurately detect oil in water from low ppb to high ppm. For this application, the TD-4100 monitors oil in water at 1 to 5 ppm and signals an operator with an alarm when the concentration exceeds the high alarm relay set-point.

    Monitoring of leaks in heat exchangers

    Optical instruments called fluorometers can very easily detect and measure dissolved petroleum hydrocarbons in water, and at very low concentrations. As shown in the study below, TD-4100 series monitors are able to measure xylene continuously over four consecutive weeks with a direct correlation coefficient of 0.9967 compared to GC grab sample analysis.

  • Monitoring TPH in Produced Sand for Overboard Discharge

    Sitelab's TD-500D analyzer is used on offshore oil platforms to test TPH in produced sand. The sand is contaminated by crude oil and must be treated prior to overboard discharge in order to meet regulatory limits.

    Validation of Salt Water Disposal Well Treatment Plants with Handheld Oil in Water Sample Analyzer

    Ideally, a continuous online monitor would be used for collecting data to determine upset frequencies, duration and normal conditions. Many of the SWD facilities and demonstration plants do not have a budget that allows for continuous monitoring. However, high frequency sample analysis can be performed on site, using a portable analyzer. Easy to use, low cost field analyzers, such as the TD-500D, are essential for optimizing the effectiveness of treatment systems during pilot studies and meeting a budget that includes frequent measurements.
