Water Analyzer Offers Enhanced Capabilities to Quantify Total Hydrocarbons & VOCs for Greater Environmental Pollution Control

Analytical Systems Keco introduces the Model 204 Hydrocarbon VOC in Water Analyzer with an enhanced method of analytically quantifying total hydrocarbons and volatile organic compounds (VOC) in cooling towers, heat exchangers, holding ponds, run-off water, and wastewater. Utilizing an exclusive sample transfer stripper and solid-state sensor, the water analyzer measures oil and VOCs directly in the water as opposed to the air around the water, a method that misses VOCs and results in non-alarm events.

It also measures very low levels (parts per billion) to detect a small leak very early before becoming an environmental issue.

The Model 204 Water Analyzer provides greater capability for environmental pollution control for wastewater treatment plants that must measure VOC contaminants to ensure water is properly treated before released, chemical/ petrochemical plants that measure VOC directly in the water to ensure no hydrocarbon product leaked from pipes, and power plants for cooling towers and heat exchanger leak detection.

In operation, liquid flows into the analyzer and enters a heated Sample Transfer Stripper (ASI Membrane Technology) unit that effectively strips the volatile hydrocarbons from the oil in the water. The carrier air, then, sweeps the hydrocarbons to a advanced solid state sensor for quantitative analysis in ppb or ppm levels. The advanced transmitter electronics quantify and display the values on a back-lit LCD and can provide outputs including a 4-20mA output loop and RS232/485 Modbus for remote and web-based monitoring and control. An optional ‘True’ Liquid Validation System by PermTube verifies proper operation of the entire analyzer system–not just the sensor–with a flip of a switch or remote activation. This onboard functional validation option introduces hydrocarbons into the analyzer flow path via a Permeation Tube.

The Model 204 Water Analyzer is more accurate in quantifying aliphatic and aromatic hydrocarbons in water (including carcinogenic compounds like benzene, toluene, and xylene) than UV Fluorescence methods that cannot measure aliphatic compounds and often provide false high readings and alarms by accidentally measuring debris and contamination. The Hydrocarbon VOC in Water Analyzer is both economically and operationally superior to inaccurate laboratory analyzers where unstable grab samples result in oil deterioration that produces analytical errors.

The analyzer is simple to maintain and does not require routine field calibrations in the field. With field-proven reliability, the Model 204 Water Analyzer provides continuous and precise analysis of clean and dirty water.
