Editor-in-Chief Elisabeth Lisican showcases a handful of features to read in the April 2017 issue of Water & Wastes Digest.
A major urban Department of Sanitation needed a system for monitoring gasoline vapors, kerosene and other hydrocarbons that might enter the screen pit area in the pump station screening room (the first step in the waste treatment process).
Because this application was aimed at detecting hydrocarbon-based spills into the system it required a monitor with low-level detection ability that would alert operators to even a minor change in hydrocarbon levels.
Solution: An eight-point MSA Chemgard Photoacoustic Infrared Monitor for 0-1,000 ppm hydrocarbon monitoring was chosen for this application. The Chemgard Infrared Gas Monitor is designed as a sample draw system with advanced photoacoustic infrared (PIR) sensing technology and is extremely stable, highly selective and can operate for months with virtually no zero drift. The Chemgard Monitor provided the customer with a low initial hardware cost, low installation cost and low routine maintenance cost (with periodic calibration of a single sensor versus eight sensors).
