• Treatment Facilities Celebrate World Water Day

  Saturday, March 24th was a busy day at the Brightwater Clean-Water Treatment Facility in Woodinville, WA, just outside Seattle. The Utility’s Education and Community Center was full of family-oriented science experiments and art projects with organized tours of the wastewater treatment plant taking place throughout the day. All in recognition of International World Water Day which had occurred two days before.

• Naegleria Fowleri And The Hot Spring

  For many people, hot springs conjure up thoughts of cleansing and purity. For centuries, humans have visited hot springs to relax and recover. But as with any natural water body, hot springs can also exhibit biota that can infect and in severe cases kill.

• Acing The Alpha Factor In Aeration

  Aeration is the heart of every activated sludge system, as well as the most energy-intensive process. When designing or modifying a wastewater treatment facility, the aeration system design will have lasting impacts on effectiveness, capital and operating costs.

• Gulf Of Mexico’s Hypoxic Zone Larger Than Ever

  Last year, the National Oceanic and Atmospheric Administration (NOAA) recorded the largest hypoxic zone in the Gulf of Mexico since monitoring began 32 years ago. Hypoxic waters, often referred to as dead zones, have dissolved oxygen concentrations of less than 2-3 ppm. They are caused by eutrophication or excess nutrients that promote algal growth in water bodies. As algae decompose, they consume oxygen creating dead zones.

• Water Industry World Records

  You may have read recently that Orange County Water District (OCWD) and Orange County Sanitation District (OCSD) set a Guinness World Record for the most wastewater recycled to drinking water in 24 hours. The record attempt kicked off on February 15^th 2018 to mark the 10^th anniversary since the districts’ Groundwater Replenishment System was launched and culminated with more than 100 million gallons per day (MGD) being produced.

• Jet Aeration Systems: A Tool For Improved SBR Operation

  Sequencing Batch Reactors (SBRs) are a variation of the activated sludge process that combine treatment steps into a single basin. Based on a fill-and-draw method, major phases of the SBR process include a cycle of fill (with or without aeration), react, settle, decant, and idle. Today, successful flow control strategies have made SBRs state-of-the-art technology. SBRs are commonly used today and are especially beneficial for many industrial applications.

• DC Water’s Unconventional Approach To Utility Management

  Over the past 10 years, DC Water has become the harbinger of the modern water utility. It’s often unconventional approach to tackling age-old problems usually elicits one of two responses from other utility professionals. The first response is one of resignation — if only I had the budget that size permits, I’d be able to do similar things. And the second is one of awe — there’s no way I have the amount of gumption to convince regulators or customers that I have a better way.

• What Happens To The Chesapeake Bay Now?

  One of the great turnaround stories in the history of our nation’s water bodies is that of the Chesapeake Bay. Since 1976 when the Environmental Protection Agency (U.S. EPA) first undertook a comprehensive study of the Bay, efforts to address excessive nitrogen and phosphorous degradation of water quality have steadily improved the Bay’s complex ecosystem.

• Does Public Outreach Help Or Hinder Acceptance Of Recycled Wastewater As A Drinking Water Source?

• Water Intense Meat Production Processes Will Have To Change

  A few years back, the Secretary of the International Farm Management Association (IFMA) announced that if the world’s population consumed food in the same manner as the citizens of the U.S., we would need 6 planet earths to keep up with demand. Now we know that the traditional diet of hamburgers, steaks and all-you-can-eat buffets across America’s heartland is slowly being diversified by a growing number of eating options, many far greener, i.e. Salad Works.
