Detection Instruments Corporation, exclusive North American distributor of the OdaLog Hydrogen Sulfide Gas Logger, was the receipt of the Water Environment Federation’s 2002 Innovative Technology Award, Instrumentation category. The Water Environment Federation is the nation’s leading technical organization for the water quality industry. The OdaLog demonstrated a significant achievement in design and operation resulting in long-term water quality improvement.
App-Tek International manufactures the OdaLog in Australia. Ross Church, App-Tek Director, states, "I’m delighted that the OdaLog received this high honor from the Water Environment Federation. The successful introduction of the OdaLog into the North American Wastewater industry has generated more research and development efforts for App-Tek International, which will ultimately benefit the wastewater industry throughout the world."
Typical applications for the OdaLog include locating and monitoring the source of hydrogen sulfide (H2S) emissions at pump stations, collection systems and receiving manholes. Once the source of the odor is determined, the unit can be used to show the effectiveness of the odor reduction strategies implemented."Many of our customers have been able to cost justify several units through chemical savings alone, realized by pinpointing the specific times that the H2S emissions occur," said Lindy Eppinger, OdaLog applications specialist.
Designed specifically for the wastewater industry, the OdaLog is totally sealed and moisture resistant. Unique features include a durable, chemically resistant body, high memory capacity, magnetic switches and an infrared communication link for programming and data downloading. The infrared link eliminates outside pin connections and corrosion problems commonly associated with such connections.
Data generated by the OdaLog has allowed many municipalities to reduce the amount of chemicals and biological agents added to combat H2S gas by determining times of high H2S gas occurrences and dosing accordingly. Better "timing" of H2S inhibiting additives has also led to reduced community odor complaints and decreased corrosion of assets within sewer systems.
The OdaLog software allows the user to configure the OdaLog through a simple graphical user interface, as well as download the data after a sampling session. The user can customize the graph to include titles, footers and labels; gas concentrations; temperature levels and data points; times and dates; and gas action levels. It also can zoom in on specific areas of the data graphs. Stored data can be exported easily to various commercially available spreadsheet formats.
