EPA's Water Report: A Good But Incomplete Start

One study cannot answer every question about water pollution risks from oil and gas drilling, nor should it be expected to. But as my colleague Nichole Saunders pointed out, the oft-quoted statement of EPA’s water study – that it found no evidence of “widespread, systemic impacts on drinking water sources”– implied to some that activities related to hydraulic fracturing had been declared risk-free.

Water Is Energy

More than 2,000 years ago, Greek and Roman engineers harnessed the power of water to drive grain mills, and the technology soon spread as far as China, where it was used to forge iron. By the 4th century, the Romans had scaled up water wheel technology to build a massive flour plant in Arles, France, powered by 16 overshot water wheels. During the Renaissance, Leonardo da Vinci sketched out visions of water-driven sawmills, forges, factories, and spinning works.

Fracking Wastewater Recycled In Four Innovative Steps

Florida-based company Ozonix developed a new chemical-free system that uses four disinfection technologies­ to treat and recycle flowback and produced water for use as fracturing fluid.

Refinery Wastewater: Benefits Of Remediation By Electrocoagulation

Crude oil is a fossil fuel formed from long-dead organisms subjected to intense heat and pressure underground. This resource is the main ingredient in the production of gasoline, diesel fuel, lubricants, kerosene, propane, and asphalt. All of these products can be made in a single refinery through a complex branching series of chemical processes. The central refining process is atmospheric distillation whereby the crude oil is fractured into different components based on their differing boiling points. Each of these fractions will be sent along to separate process to be turned into the different oil products. Therefore, remediation of refinery wastewater from these different processes can be quite complex.

2 Applications That Triggered The Rise Of Coriolis Flow Measurement

Coriolis measurement has been adopted as a default technology in many application scenarios due to its high accuracy and immunity to process variables (temperature, pressure and flow profile). However, Coriolis wasn't always widely accepted. Two applications, in particular, helped what was once a nascent flow measurement technology gain a foothold in the marketplace.

(E)-2-Nonenal In Beer

Numerous compounds contribute to changes in beer flavor as it becomes stale. One of these compounds, (E)-2-nonenal, has been investigated as a major source of the papery/cardboard flavor that develops in aged beer.

A Ready-To-Ship Rental Saves The Day

Aire-02 was approached by a large sugar beet processing facility that was in desperate need of a rapid and effective solution for their deteriorating wastewater treatment system.

Springdale, Arkansas, Wastewater Treatment Plant Operators Call Headworks Screens 'Bulletproof'

The Poultry Capital of the World is a city in northwest Arkansas in the heart of the Ozark Mountain range. Springdale, Arkansas, the fourth largest city in the state, is the headquarters for Tyson Food Corporation, the world's largest meat-producing company. The city was founded in the mid-1800s and has been a hub for agriculture and industry in the region since then. In addition, the region is home to outdoors activities like fishing, hunting, camping, boating, etc., and the natural, outdoors life is enjoyed by many residents as well as visitors to the area.

Wastewater Disinfection And Energy Generation Make 'Hot' Couple

When the Pasteurization Technology Group (PTG) first presented their heat-based wastewater disinfection system to a group of environmental engineers, they didn’t get the response they expected.

Flow Meter Ensures A Smooth Running Recovery Process At Bakery Production Plant

Employing roughly 5,000 workers in 12 countries, Vandemoortele bakery and production plant owes its success to high standards of quality, innovative production technologies, and a flair for finding economic alternatives. The latest example is the SITRANS FC430 Coriolis flow meter.

If Israel Can Find Common Ground Around The Environment, Why Can't Texas?

Deep in the Israeli desert is an academic institute that is building peace in the region by putting nature at its center. The Arava Institute, in partnership with Ben Gurion University, brings students from Israel, Palestine, Jordan, and around the world to find common ground around environmental problems and build trust — and peace — from there.

Pile Cloth Media Filtration For Clean Utilities

Cooling towers and boilers consume the most fresh water in the industry, with industrial process waters carrying the balance. Power plants and refineries use more water volume for the cooling process than any other area of the facility. Mining and food and beverage industries consume higher volumes for their processes. Clean water may come from a range of sources, including clarified surface waters, groundwater or properly treated wastewater (reuse) sources.

Cooling Tower Crisis: How Hydrogen Peroxide Scrubbed Away The Bacteria Buildup

A West coast power plant needed an immediate solution to clean its cooling tower that was fast, cost effective, and did not require removal and manual cleaning of the tower's fill material. 

Holistic Energy-Water Planning: Hedging Your Bets In A Water-Stressed World

You probably have some sort of insurance – for your healthcare, car, house, or apartment. Acting on climate change is also like insurance. It is all about managing the risks.

Topeka WTP Installs Integrity A-758 PLUS™ Lime Slaker System To Replace Existing Lime Slaker

The Topeka Water Treatment Plant (WTP) — a 60 million gallon per day facility - serves Topeka, Kansas and surrounding areas. Built in 1945, the plant underwent several renovations with the most recent upgrading the plant to its current capacity in 1993.

In 2015, plant officials decided to replace the first of the existing slakers and, after considering offers from several slaker suppliers, chose the A-758 PLUS™ paste-type lime slaker manufactured by Integrity Municipal Systems, LLC (IMS). Read the full case study to learn more.

EPA Researchers Develop Tool That Helps Water Quality Managers Meet Nutrient Load Targets

Nutrient pollution is one of America’s most widespread, costly, and challenging environmental problems. This pollution can occur when excess amounts of nutrients, such as nitrogen and phosphorus, run off from land into streams, rivers, lakes, and other water sources. To help water quality managers reduce nutrient pollution, EPA researchers developed the River Basin Export Reduction Optimization Support Tool (RBEROST), a regional online tool currently available for the Upper Connecticut River Basin that provides low-cost solutions to meet nutrient load targets.
