Z-88® Radium Treatment Process - City Of New Underwood, South Dakota Case Study

This radium removal pilot study was conducted for the City of New Underwood, South Dakota. New Underwood’s water system contains concentrations of radium and gross alpha in excess of the Maximum Contaminant Levels (MCL).

The Value Of Virtual Reality In Wastewater Inspection

Discover how AR and VR are helping workers in the water and wastewater sectors visualize buried utilities from aboveground, enabling the public to tour their local treatment plants, and more. 

Compact Footprint And Flexible Hydraulics Ease Initial Expansion, Leave Room For Future Growth

When Plainfield, IN, needed to double their permitted capacity from 2 MGD to 4 MGD at their South wastewater treatment plant, they faced a dilemma. Like most treatment plants, space is at a premium, and compact design was needed not only for the current expansion, including the addition of a post aeration structure, but to preserve as much room as possible for projected future expansions.

Case Study: Steel Processor Wastewater Recycle

The reuse of industrial wastewater is becoming increasingly common because of water shortages, environmental necessities, economic incentives, government mandates, and societal desires. By David Christophersen, Technical Support Manager, Veolia Water Technologies

Carbon Dioxide For pH Control Of Landfill Leachate

A landfill operator’s leachate treatment plant in Missouri required pH reduction following lime-softening and prior to the biological wastewater treatment process. Carbon dioxide (CO2) was chosen as a substitute for sulfuric acid due to improved process control and a reduced tendency to form scale.

Ontario - Modular MBR Sewage Treatment Plant

The Detour Lake deposit is Canada’s largest undeveloped pure gold reserve, and is located approximately eight kilometers west of the Ontario-Québec border, 180 kilometers northeast of Cochrane, Ontario. Gold production at the site began in early 2013 and production at the mine is expected to grow over time.

Pentair Next-Gen Submersible Helps Protect Danville, Indiana

The County Home Lift Station in Danville, Indiana, plays a crucial role in managing wastewater for a diverse area that includes a regional hospital, a county jail, a landfill, and numerous businesses and residences.

AquaSBR® System Treats High Strength Vegetable Processing Waste

In early 1993, Birds Eye Foods was faced with a difficult decision, to construct a new wastewater treatment facility or to retrofit their existing flow-through extended aeration treatment system

White Paper: Water Reuse Strategies: Steel Industry Case Studies

The steel industry has historically presented challenges for effective water treatment because it is a high water user and the applications may involve high heat, critical noncontact cooling, direct contact cooling, high suspended solids waters, oil and grease contamination, and complicated cascading. By Dave Christophersen, Veolia Water Technologies

A Time-Based Alternative To Multi-Stage Biological Nutrient Removal

A phase-activated sludge system (PASS) reduces energy consumption by combining the aerobic and anoxic tanks and alternating diffusers between the on and off position based on a preprogrammed schedule.

Analyzing Total Organic Carbon In Sea Water

The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

Pile Cloth Media Filtration Effectively Removes COD And TSS From Oil Refinery Wastewater

This application profile focuses on two test sites with different treatment requirements and describes how Aqua-Aerobic Systems’ OptiFiber® pile cloth media filtration was used at both sites to address the removal of harmful constituents from refinery wastewater.

Waste Technologies Transform Problems To Profit

Anaerobic digestion processes that radically improve the quality of wastewater while delivering green energy extracted from biological waste streams are emerging as a profitable way for agricultural and food processing industries cope with the twin impact of drought and pollution challenges.

Biogas Measurement From Wastewater To Power Plant

Stockholm water company produces biogas from their wastewater facility which feeds Scandinavian Biogas for energy production. As they need to accurately meter what they sell to the energy facility they used a project contractor firm to engineer and define the best solution for the project.

Environmental Applications Of The Agilent 1290 Infinity UHPLC: The Evolution Of Chromatography This application note presents examples of the use of UHPLC (ultrahigh performance liquid chromatography) for environmental applications using the new Agilent 1290 Infinity LC. By E. Michael Thurman and Imma Ferrer Center for Environmental Mass Spectrometry Department of Environmental Engineering University of Colorado Boulder, CO, USA

Recording & Control: Aeration Control In Wastewater Plants – Accurate And Fast Control Of Aeration Process

Waste water, or raw sewage, is water that drains from toilets, sinks, showers, baths, dishwashers, washing machines and liquid industrial wastes.

Reduce SBR Maintenance Costs With Jet Aeration

Aeration has been a primary method for treating municipal and industrial wastewater for over a century. It is a natural way to reduce biological oxygen demand (BOD) and control odors. In the SBR process, aeration helps foster nitrification by bubbling air through the mixture of wastewater and activated sludge, encouraging the multiplication of aerobic microbes which consume nutrients and convert ammonia into nitrites and nitrates.

Primary Wastewater Treatment: Influent Monitoring

The raw sewage entering a wastewater treatment plant comes from a variety of sources. In addition to effluent from domestic users, effluent from industrial users and storm water run off can be present.

An Ideal Aeration System For Aquaculture Corporations

Successful aquaculture corporations know that there are many variables that need to be accounted for in order for the bottom line to be “in the black”, let alone grow annually by 10-20%.

Repair Or Rethink

The Moundsville Wastewater Treatment Plant in West Virginia chooses not to fix a broken blower unit, but rather to correct an outdated approach. The result is a savings of $50-60K a year in energy costs.
