In the fall of 2008, AdEdge was selected by Village of Corona, NM to design, manufacture, and startup a water treatment system for the removal of iron and manganese. By Adedge Technologies Inc.
Everyone wants pathogen-free drinking water, and adding chlorine is a great way to get it. Unfortunately, the dirtier a water treatment plant (WTP)’s raw water inflow — in terms of natural organic matter (NOM) or microbial organisms — the more disinfection byproducts (DBPs) the chlorination process will generate in the form of trihalomethanes (THMs) and haloacetic acids (HAAs). Those DBPs increase the risk of non-compliance with the U.S. EPA’s Disinfectants and Disinfection Byproducts Rules. Choosing the right instrumentation to measure NOM through spectral absorption coefficients (SACs) can have a big impact on treatment strategies — in terms of both costs and compliance performance.
On his way out of office, Barack Obama made a final effort to bolster the Waters of the United States rule (WOTUS), which has drawn controversy since it was issued in 2015.
In the early 1990’s, the volatile organic compounds (VOCs) tetrachloroethylene (PCE), and trichloroethylene (TCE) were discovered in the vicinity of several city water supply wells near the city of Stockton, California.
It may seem farfetched, but the reality is that many Americans don’t have regular access to clean drinking water.
The quality of drinking water is regulated by a variety of guidelines, such as the EU Council Directive 98/831,2 and WHO guideline. The key principles used to define these limits consider both health hazards and sensory and technical reasons. Iron, for example, does not exhibit a risk for health in concentrations usually found in drinking water.
UV disinfection with SENTINEL® provides a proven barrier to harmful pathogens that can be present in source water. This includes bacteria, viruses and chlorine-resistant protozoa such as Cryptosporidium and Giardia.
The oil industry has a wastewater problem. As shale drilling has grown, so has the issue of how to dispose of the huge amounts of water required of the process. After years of injecting brackish wastewater back into wells thousands of feet below the surface, scientists have become concerned that pressure in disposal wells is building to unsustainable levels from overuse.
A couple of weeks ago, Environmental Protection Agency (EPA) administrator Scott Pruitt called PFAS groundwater contamination “a national priority” and pledged action at an EPA national PFAS leadership summit.
Badger Meter has and will continue to manufacture and provide products that meet the requirements of current and future lead-free standards. This white paper discusses these changing industry needs both as they relate to Badger Meter products and to water utilities in general.
