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.

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.

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.

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.

Versatile Vortex Valves

Water industry officials often consider vortex valves a novel technology for outlet flow control within stormwater detention systems. That's why the majority of the 17,000+ vortex valve installations in Europe and North America are used in stormwater detention. These units, however, can be implemented in water management systems to reduce erosion, aerate discharge, and equalize flow, among other things.

National vs. State Rules

Nationally established stormwater regulations can conflict with statewide enforcement and the trickle-down effect may leave local jurisdictions as well as developers confused about who is regulating what and why the regulations were organized in this way.

Case Study: In Municipal Chambers

Population and regulatory demands, an increased awareness of the need to protect sensitive areas, and the value of water as a resource are driving new ways of thinking about how decentralized wastewater treatment can be used to manage these issues.

Case Study: RTO Replacements with No Upfront Capital

After operating two regenerative thermal oxidizers (RTOs) for the last 25 years, Soliant LLC of Lancaster, S.C., considered what repairs were needed to ensure reliability. The company asked Dürr Systems, Inc. EES, a supplier of RTOs, for recommendations.

The AAI Rule and SOX Intersect

November 1, 2006, was an historic day for the environmental due diligence industry. That’s the date the U.S. Environmental Protection Agency’s All Appropriate Inquiry (AAI) rule took effect, changing the environmental due diligence requirements for those seeking to qualify for cleanup liability protection under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA).
