The Problem
The City of Kenner Louisiana had an odor problem at a pump station adjacent to Greenlawn Terrace elementary school. Parents were dropping off and picking up their children before and after school, right in front of the pump station in addition there was a manhole cover in the street omitting odors. Besides parents complaining of the smell, neighbors had to smell the pump station. After a failed attempt to use ozone injection, chemical treatment upstream of the pump station, and deodorant blocks to solve the odor problem the City through they are operations contractor (Veolia) contacted KCH Engineered Systems for help. Veolia had worked with KCH Engineered Systems in the past on odor control projects in the Caribbean and know KCH could provide a solution to the odor control issue as well as the corrosion issues with the pump station. Veolia conducted a four-month site test to determine the odor control system would see peaks of 390 PPM H2S and an average of 100 PPM H2S and that 99% removal wasn’t enough for this location. Based on this information KCH Engineered Systems design team proposed a Biotrickling Filter followed by a polishing stage Carbon unit.
The Solution
The City of Kenner settled on a Biotrickling Filter followed by a Carbon Adsorber at the recommendation of their operations Contractor (Veolia). KCH Engineered Systems was selected as the odor control system supplier. Below is a picture of the system install for the City of Kenner. The City has not received a single odor complaint from this pump station since the system went online. One neighbor to the pump station stop by the pump station during a system inspection and expressed his appreciation for the City installing the odor control system and that he had not smelled anything since the system was installed.
Conclusions
The City of Kenner is extremely pleased with the KCH Engineered Systems odor control system, so pleased they have given KCH a second order for another pump station odor control system of the exact design.
