Pennsylvania American Water (PAW) was receiving complaints about the unsightly color of their water, which contained manganese well above U.S. EPA guidelines. The quest began for a cost-conscious and easy-to-operate solution (appropriate to a small, stand-alone system) that would restore water quality by greatly reducing both manganese and iron.

Clear Choice Emerges For Small-System Iron And Manganese Removal
Pennsylvania American Water (PAW) was receiving complaints about the unsightly color of their water, which contained manganese well above U.S. EPA guidelines. The quest began for a cost-conscious and easy-to-operate solution (appropriate to a small, stand-alone system) that would restore water quality by greatly reducing both manganese and iron.
Arsenic 101: 5 Questions Answered
Arsenic in water is one thing, but arsenic in beer? This is getting out of hand. While the drinking water supply is clearly much more of a concern than the beer supply, the sobering fact is that arsenic, a known carcinogen, is far too prevalent in the environment.
Chemical Dependency: A Breakthrough Approach To Ultra-Low Phosphorus
Until recently, chemically enhanced primary treatment (CEPT) wasn’t considered a viable option for removing phosphorus to very low levels — even less so when used with membrane bioreactors (MBR). The trailblazing design of a new reclamation facility in Spokane, WA, has changed that view.
Should You Trash Your Flow Meter?
Generally speaking, market research reports aren’t terribly exciting reads, but they are at times enlightening. Studies on how specific technologies are being applied can reveal trends for the industries they serve — for example, flow meters in water and wastewater. I recently came across some interesting analysis on the subject, homing in on what they reveal about our corner of the world.
