Getting Smart About WaterWe’ve all heard the adage, “Work smarter, not harder,” but are we living it in the water industry? While the status quo may have merit and is almost certainly more comfortable, these trying times of big problems and small budgets beckon a new approach — to get smarter about water. You likely know the term “smart water” as it pertains to instruments that collect and interpret data, but the focus of this edition of Water Online The Magazine is to first engage the data-collecting instrument within each of us — our brains.

Go With The (Change Of) Flow: 3 Overlooked Tasks At WWTPs
There are certain requirements incumbent upon the wastewater operator when the volume and nature of waste coming into the wastewater treatment plant changes — first and foremost of which is recognition. That’s the easy part...
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.
