Sun-Activated LilyPads Remove Contaminants Without Chemicals

Puralytics LilyPads are hardly noticeable in the ponds, lakes, and catchment areas where they are deployed. Made of mesh and plastic, the flat, 1-meter diameter disks could even be confused for their plant namesake if not for their white color.

Smarter Source Water: Could New Thinking Unite Industry And Environmentalists?

AMD can be a valuable resource for the oil and gas industry and result in cleaning up thousands of streams and rivers in the nation.

Resolving High PH For Mining Operations

For an open-pit taconite mining operation in Minnesota, high pH groundwater required round-the-clock pumping to comply with discharge permit limits. After management installed a control system to neutralize the pH, the treated water leaving the site now meets permit limits. Read this case study to learn more about the installed system and results.

What To Know About The EPA's New Effluent Guidelines

The U.S. EPA’s recently released Preliminary 2016 Effluent Guidelines Program Plan indicates the industries and pollutants that the agency has its eyes on for potential future regulation.

New Hampshire Puts $350 Million To Work From A Successful Lawsuit Over MTBE Contamination

From cleaner water to infrastructure upgrades, good stories are easy to find after the state of New Hampshire set out to hold polluters accountable for contaminating groundwater with methyl tertiary-butyl ether (MTBE), a gasoline additive now banned or limited in several states. Through private well testing, watershed protection and new water facilities, the people of the Granite State are turning the tide on water contamination and restoring the safety and reliability of their drinking water supplies thanks to bold action to make sure polluters pay for damage.

The DELUMPER®: A Sweet Success At ADM

ADM Cocoa Plant in Hazle Township, Pennsylvania needed help with their cocoa bean production. The plant processes two and a half million pounds of cocoa beans each day, turning them into cocoa powder, cocoa butter, and chocolate liquor. The company needed a machine to process sugar with over-sized lumps that could occur in transport or storage. Unless these agglomerated clumps were reduced to a granular form, the process could not work dependably. The machine also had to handle the large quantity of sugar processed daily and be sanitary.

3 Innovative Ways PepsiCo Is Implementing Circular Water Systems The pervasive and increasing incidence of water stress could perhaps be the most clear-cut consequence of climate change. As weather patterns become increasingly erratic and destructive, floods and drought are continuing to deplete water resources. We're no longer seeing predictable rainy and dry seasons to balance water tables. Couple this with growing and migrating populations that create an ever-increasing water demand, and the result is the undeniable water stress we're seeing globally.

Advances In Flowmeter Technology

This article disucsses two trends turning the flowmeter industry on its ear: advances in flowmeter diagnostics and the adoption of smartphone-like technology to improve access and communications.

5 Approaches to Treating Wastewater in Food (Meat) Production

The meat processing industry consists of two major groups - slaughterhouses and packinghouses. A slaughterhouse is a plant that harvests animals and whose main product is fresh meat as a whole or smaller meat cuts. A packinghouse is a plant that both slaughters and processes fresh meat to cured, smoked, canned and other prepared meat products.

Aeration System Upgrade At The Effluent Treatment Plant For The Largest Cheese Manufacturer In The UK

Dairy Crest Davidshow Creamery in Camelford, England is the largest cheddar cheese manufacturer in the UK.

Stator Cooling Water In Power Generation Plants

Power Generation plants produce electricity by converting one form of primary energy (nuclear or non-nuclear) to motive power in order to drive generators and produce electricity.

Dechlorination Of RO Feed Water In Power Station

Plant Bowen, a coal-fired power station in Georgia, successfully implemented Atlantium's HOD UV technology to eliminate microbial growth and improve the performance of their reverse osmosis system. The HOD UV system removed chlorine, reduced maintenance costs, and extended the lifespan of membranes.

SuperDisc™ Filtration System Case Study

Glendale Heights Wastewater Treatment Plant discharges treated water to the East Branch of the DuPage River in Illinois.

Design And Care Of Reverse Osmosis Systems, Part 2: Upstream Equipment

The success of a new reverse osmosis (RO) membrane system is often directly related to its pretreatment. The previous section of this article discussed RO design issues and introduced how a pilot study should include a study of its probable pretreatment equipment since the pretreatment performance will directly affect the performance of the RO system. However, piloting the upstream processes can be challenging in sizing these components for the pilot RO unit’s low flow rate.

Is Your Water System Ready For Population Growth?

Utilities are faced with myriad threats looming in the future, but chief among them is increased stress from population growth. In Denver, comprehensive planning for that future is underway.

Overcoming Flow Measurement Challenges In Wet Gas And Open Stack, Rain-Down Installations

Wet gas is a challenge to measure in a number of industries, including those with combustible gases that represent a safety hazard. In the laboratory, today’s air/gas flow sensors and measurement technologies operate at their highest accuracy and greatest reliability in air or gas free of moisture, droplets, particulates, etc. The real industrial world, however, is a much different environment where moisture can be entrapped in one form or another in air or gas flow streams with variable gas compositions and flow rates.

Stator Cooling Water In Power Generation Plants

Power Generation plants produce electricity by converting one form of primary energy (nuclear or non-nuclear) to motive power in order to drive generators and produce electricity.

How Golf Courses Deal With Wastewater

Maintaining a golf course has a lot of challenges. Often, one of those challenges is how to clean your golf course care equipment. The equipment you use to clean and maintain your golf course very quickly finds grass clippings, soil, and other debris enmeshed in it, and you need to remove these materials regularly. The type of washing you need to do to clean that equipment, however, creates wastewater — and improper wastewater disposal procedures could see you running afoul of U.S. EPA regulations and receiving unwanted fines.

Reducing And Reusing Water In Steel Manufacturing

The art of manufacturing steel for industries is well over 100 years old. Within this time, the steel business has fulfilled consumer needs, including construction, transportation, and manufacturing. The steel manufacturing process is quite intensive as it requires a lot of water to cool down the application. Steel plants constantly look for strategies that can help sustain the steel for a longer time by efficiently improving water and energy consumption.

Lobbying In PFAS Industry Is Rife Across Europe — The Inside Story

A team of academic researchers, lawyers, and journalists from 16 European countries has exposed a huge lobbying campaign aimed at gutting a proposed EU-wide restriction on the use of “forever chemicals.” This campaign saw significant increases in the lobbying expenditure of major producers of per- and polyfluoroalkyl substances (PFAS).
