Odor complaints have become an all too familiar subject to WWTP managers. They are not only expected to manage their plants effectively and efficiently, meeting both regulatory specs and budget requirements – they are also expected to be good neighbors and keep odor under control. This article describes the successful odor control efforts of the South Dearborn Regional Sewer District located in Lawrenceburg, Ind.
The goal of this article is to demonstrate that the Shimadzu TOC-VW can effectively oxidize the Humic Acid (HA) matrix at high accuracy and precision levels never before witnessed by the wet chemical TOC community. The Shimadzu TOC-VW Carbon analyzer is the only TOC on the market that uses three oxidation techniques of UV light, heat, and persulfate in a single analyzer.1
Humic Acid: A Complex Molecule, A Simple Solution
To make the most of its resources, including operator time and energy, Warrington Township Water and Sewer Department--located in Bucks County, Pennsylvania--installed a compact sequencing batch reactor (SBR) system when the facility was built four years ago. And an equally hardworking Hach OptiQuant SST Analyzer, installed two years ago, keeps a vigilant eye on the final product.

Part one of this article appeared in the February issue and described how nanofiltration, reverse osmosis and electrodialysis reversal are being run side-by-side at the Brackish Water Demonstration Facility in California.
In Port Hueneme, California, a state-of-the-art desalination facility uses three brackish water desalination technologies: reverse osmosis (RO), nanofiltration (NF) and electrodialysis reversal (EDR), operated side-by-side to produce over three million gallons per day (mgd) of high quality drinking water. The Brackish Water Reclamation Demonstration Facility (BWRDF) is the cornerstone of the Port Hueneme Water Agency’s (PHWA) Water Quality Improvement Program. In addition to providing desalted water for local use, the BWRDF also serves as a full-scale research and demonstration facility.
