AWWA CEO David LaFrance thanks water professionals nationwide for keeping water safe for drinking
Dec. 16, 2014, marked the 40th anniversary of the Safe Drinking Water Act (SDWA), which today includes regulations for more than 90 contaminants. American Water Works Assn. (AWWA) CEO David LaFrance issued the following statement to mark the occasion.
Iron is one of the Earth’s most plentiful resources, making up at least 5% of its crust. In well water, iron is usually found as ferrous iron, which is in a dissolved state, potentially causing water to appear clear when first drawn from the tap.
Oxidizing filters combat problematic iron contamination
Industrial water treatment can be classified by the following categories (not including wastewater treatment, which is a separate topic):
- Process water treatment;
- Boiler water treatment; and
- Cooling water treatment.
Water treatment is used to optimize most water-based industrial processes, including heating, cooling, processing, cleaning and rinsing, so that operating costs and risks are reduced.
Proper sizing & media selection for successful systems
I have four children under 10 years old, so as you can imagine, my house is filled with excitement—wrestling, roughhousing and playing sports. One of my favorite activities is to play superheroes with the boys. It has been a blast to see my sons enjoy many of the same superheroes I loved as a boy: Superman, Spiderman, Batman, the Hulk, Wolverine, Captain America and many more. Ultimately, the boys like every hero and the special powers or cool gadgets they use to defeat bad guys, but our household favorite has to be Iron Man.
Safe and effective treatment for the ‘troublesome trio’
Elevated levels of arsenic, iron and manganese prompted the Resort Village of Kannata Valley in Saskatchewan, Canada — a community of 149 households situated on the north shore of Last Mountain Lake, approximately 50 km northwest of Regina — to seek a treatment solution for its drinking water. The community water system is served by an artesian well that provides drinking water for approximately 250 residents. In November 2009, AdEdge Water Technologies LLC was selected by the community to supply an arsenic, iron, manganese and turbidity treatment system.
