Case study: Optimizing RO

Reverse osmosis treatment requires sufficient feedwater pretreatment to prevent membrane fouling. Depending on the feedwater, pretreatment can be critical to ensuring a sustainable process.

Pump and Treat

When it rains hard in Collierville, Tenn., a sewer pump station right outside the gates of the Shelton Road Wastewater Treatment Plant automatically becomes part of the plant.

Chemical Continuum

Industrial research labs often manage chemical and hazardous waste storage and removal separately, using different contractors at various points in the handling process.

Connecting the Dots

Even if you don't believe global warming is “real" or support U.S. efforts to regulate greenhouse gases (GHGs), the cold hard fact is, this country is headed for GHG regulation … and fast.

A Heated Exchange

A nine-year-old company based in Zurich, Switzerland, has been busy persuading property owners to take a second look at their wastewater.


Superfund Follies Part II

Through 2005, Superfund, has resulted in the expenditure of more than $35 billion in federal funds and an unknown amount of private funds.

So Many Targets

Many water and security experts agree that the U.S. water supply offers an attractive target for terrorists, and that threats could come from either contamination or from disruption of the distribution system.


AIAM Supports National, Not California, Approach to Auto Emissions

Michael J. Stanton of the Association of International Automobile Manufacturers (AIAM) testified at a March 5 public hearing on the U.S. Environmental Protection Agency’s reconsideration of whether to grant California a waiver to regulate greenhouse emissions from automobiles and light trucks.

Assessing Energy Use, Navy-style

Homeowners tend to turn the thermostat down after the high energy bill arrives. Comfort sometimes loses out to cost, which incidentally lowers consumption. The U.S. Department of Navy, which comprises more than 64 installations worldwide, requires the sharp skills of an entire accounting department to make its calculations.

From the Top: Q & A with Ed Gildea

Converted Organics was incorporated under Delaware laws in January 2006. It merged with Mining Organics Management LLC and Mining Organics Harm River Rail Yard LLC, its predecessor organizations, the following month in transactions accounted for as a recapitalization.

Software Update 2009

Software tends to make work easier -- if it works correctly and/or if the user has been trained in the proper way to use it. But once trained, users often find that something is lacking so companies respond with upgraded versions or new versions that incorporate another regulation.

Reliable Power Distribution

Two independent power sources are better than one for wastewater treatment facilities, according to U.S. Environmental Protection Agency guidelines. These sources can either be independent utility feeds or a utility feed with on-site generation.

Wet Electrostatic Precipitators

Fredrick Cottrell first used wet electrostatic precipitators (ESPs) in 1910 to control acid mist emissions at a smelting operation in Selby, Calif. Since then, wet ESPs have been a mainstay of the sulfuric acid mist manufacturing industry, used at pyrometallurgical smelters and acid regeneration plants worldwide.

Case Study: Pebble Beach

The Pebble Beach Community Services District is a public agency formed in 1982 to collect and treat wastewater as well as provide fire protection and garbage pickup service to its nearly 4,500 residents.


From Idealists to Apologists…and Back Again?

In university, we tackle big challenges with innovative solutions. Economic theory, stakeholder collaboration, moral reasoning, and assumptions win the day. So when we graduate, why shouldn’t we be able to implement those solutions?

What's It All About?

Regulated facilities can expect change with a capital C in 2009 in the areas of global warming, hazardous air pollutants, new source review, and enforcement. These changes will come from the Obama administration, rules promulgated in the final days of the Bush administration, and judicial opinions rejecting or modifying past U.S. Environmental Protection Agency actions.

Underwater Temperature Loggers

Whether it is on coral reef bleaching, industrial thermal loading, or modeling freshwater fish populations, researchers and resoure managers must have temperature data collection methods that are accurate, reliable, and practical.

The UN-Comfort Zone

Will You Freak-Out or Hunker Down?

Sometimes motivation is forced upon us.


The Sky Is Falling?

As Reality Undermines Models, Global Warming Become Less Tenable

You're Invited!
