In drinking water treatment’s ongoing battle between disinfection and disinfection byproducts (DBPs), most water utility customers are oblivious to the process. One thing they do notice, however, is when their water smells or tastes bad. Here are some insights that can help water treatment plant (WTP) operators deal with their internal concerns about DBPs and residual chlorine or ammonia levels, as well as their external concerns about customer perceptions of water quality.
As fresh water supplies dwindle, the use of sea water becomes more attractive. New technologies are making reverse osmosis (RO) a more effective and cost-efficient method for desalination. Utilizing an effective pretreatment system to improve the quality of the feed water traveling through the RO membranes will aid in improving the performance of your membrane system.
1,4-Dioxane is a contaminant that is known to linger in groundwater and have adverse health effects when consumed. Worse still, it can pose some significant treatment challenges to the operations tasked with eliminating it.
There is little doubt about the importance of taking turbidity readings as part of drinking water treatment. However, there are certain misperceptions about the associated requirements and procedures needed to confirm the validity of those readings. The major points of confusion seem to revolve around perception of the terms “approved,” “calibration,” and “validation.” Here is a quick synopsis on what you really need to know about meeting U.S. EPA Method 180.1: Determination of Turbidity by Nephelometry for accurate turbidity readings.
When California’s AB2022 went into effect earlier this year, allowing the bottling of advanced purified reused water for educational purposes, Orange County Water District (OCWD) and Orange County Sanitation District began the #GetOverIt! campaign to continue to push for consumer acceptance of recycled water systems.
AdEdge Water Technologies specializes in inorganic contaminant removal, relying on a variety of treatment technologies such as adsorption, coagulation, oxidation, filtration, RO and ion exchange. Rich Cavagnaro, CEO of AdEdge Water Technologies and Ronit Erlitzki, Director of Business and Product Development for the Company, recently joined Water Talk to discuss a biological treatment technology for groundwater wells.
A lot has changed over the past 15 years. Back in the early 2000s, many utilities weren’t interested in understanding what was in their water beyond the contaminant and disinfection byproduct levels they were regulated to comply with. But as Pat Whalen, President and CEO of LuminUltra, explains in this ACE 2018 Water Talk interview, a steady stream of ongoing education and the modern data storage and analytics that cloud computing provides, has developed some rabid fans eager to explore the microbiology of their water systems.
Sampling and laboratory testing are major responsibilities for water professionals. Test results are used for process control, and ultimately to determine that water is safe for drinking, reuse, or discharge to the environment. Regulatory agencies rely on reported results for proof of permit compliance. So, obtaining representative, properly collected and preserved samples is the first critical step to ensure accurate test results.
Those who are philanthropically-minded need look no further for a cause than that of water. After all, this is a fundamental aspect of human existence and one that is shockingly scarce in some parts of the world.
The Merrimack River is considered one of the major beneficiaries of the Clean Water Act of 1972.
