Wet Chemical TOC Analysis

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

Automated Treatment, Monitoring System Keeps An Eye On Operations

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.

Project Compares Brackish Water Desalination Technologies - Part 1

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.
