"Positive Step..."

 
WEF Supports EPA'S Water Quality Trading Policy

(Alexandria, VA) - The Water Environment Federation (WEF) today welcomed the release of the U.S. Environmental Protection Agency's (EPA) Water Quality Trading Policy. According to WEF Executive Director, Bill Bertera, "WEF supports many of the provisions in the Policy and believes it is a positive step towards recognizing trading as a tool to achieve water quality improvements. Overall, the Federation strongly supports the concept of trading as an innovative approach to reaching water quality goals."

Click hereThe purpose of the Policy is to encourage states, interstate agencies, and tribes to develop and implement voluntary water quality trading programs that facilitate implementation of TMDLs, reduce the costs of compliance with Clean Water Act regulations, establish incentives for voluntary reductions, and promote watershed-based initiatives. As a follow-up to EPA's "Framework for Watershed-Based Effluent Trading", the Policy draws upon lessons learned from pilot programs and state experiences developing water quality trading programs conducted since the September 1996 document was released. WEF supports EPA's water quality trading initiative and endorses trading as a potentially cost-effective, market-incentive method to further local, regional, and national clean water goals.

WEF supports EPA's recognition that trading is a voluntary approach that may be used to more efficiently protect and restore water quality and beneficial uses of the nation's waters. Specifically, WEF supports the Policy's emphasis on watersheds and cooperation between point and nonpoint sources. The Federation has long advocated the watershed management approach and the principle that water quality oriented activities across regulatory programs should be combined to form a strong, integrated basis for planning, priority setting, and implementation on a watershed basis.

WEF initiated Water Quality 2000, a cooperative effort of over 70 organizations to propose and promote national policies and goals for the 21st century to protect and enhance water quality. As a leader in education and technology transfer, WEF has also worked in conjunction with EPA and other federal agencies to sponsor four national Watershed Management conferences and two national TMDL conferences.

New Features and Enhancements

 
USFilter Issued Patent for Diffuser System

WAUKESHA, Wis., Jan. 17, 2003 – USFilter recently received a key patent for its DualAir diffuser assembly and hollow rivet attachment. U.S. Patent No. 6,464,211, issued Oct. 15, 2002, describes an innovative design for attaching 9-in. membrane disc diffusers to an air distribution pipe.

Click hereDeveloped by USFilter’s Envirex Products, the DualAir fine-bubble diffuser system is used to aerate wastewater inside a treatment tank. The system consists of two diffuser bases connected by a curved saddle that fits over conventional PVC air distribution piping. This allows twice as many saddles to be mounted to a given length of pipe, compared to conventional single-pod diffuser designs.

The DualAir diffuser saddle is secured to the aeration pipe by a pair of hollow core rivets with internal threads. Each hollow rivet serves as a regulating orifice, helping to ensure uniform air distribution to all of the diffusers on the distribution pipe network.

Conventional diffusers are permanently glued to the air distribution pipes, and are typically attached at a single, small area at the top of the pipe. For this reason, the joints are more likely to break when excessive torque is applied to loosen a threaded retaining ring during membrane replacement, especially in cold weather.

With the DualAir fine-bubble diffuser system, the two-rivet connection between the diffuser assembly and the distribution pipe grips the pipe over a large area, much like an “eagle claw,” reducing the possibility of damage when torque is applied during maintenance.

This increased flexibility in mounting the diffuser assembly to the distribution pipe network also simplifies the task of mounting numerous diffuser assemblies along the length of a distribution pipe when submerged in a treatment tank, and further minimizes the cost associated with installing, cleaning and/or replacing the diffuser assembly.

USFilter Corporation, a Vivendi Environnement company, is North America’s largest water company providing comprehensive water and wastewater systems and services to commercial, industrial, municipal and residential customers. Visit the company’s web sites at www.usfilter.com

Drinking Water Industry

 

AWWA & Commerce Dept. Partner To Expand Exports

WASHINGTON D.C. – The American Water Works Association (AWWA), the largest drinking water organization in the world, today announced an agreement with the U.S. Department of Commerce to enhance international opportunities for the drinking water industry. The agreement between the two organizations recognizes the critical importance of environmental technologies to the U.S. and international economies, and the contribution of those technologies to global sustainable development and protection of public health.

Established in 1881, AWWA is the oldest and largest nonprofit scientific and educational organization dedicated to safe drinking water in the world. AWWA has 56,000 members worldwide and its 4,500 utility members serve 80 percent of America’s population.

“This alliance creates an opportunity to enhance international trade of environmental technologies and to develop infrastructure projects that support growing populations, economic development, and protect the public health for people worldwide,” said Jack Hoffbuhr, AWWA executive director. “AWWA is truly very honored to partner with the U.S. Department of Commerce and to exchange resources so that we may collectively work toward a unified goal of protecting public health.”

“This agreement demonstrates our commitment to public-private partnerships that stimulate international trade,” said Linda Conlin, Assistant Secretary of Commerce for Trade Development. “This will benefit the U.S. environmental industry, enhance U.S. exports and advance the Administration’s commitment to provide better access to safe drinking water to people around the globe.”

The benefits of this mutual agreement to the drinking water industry and international community include:

  • The opportunity to continue to advance programs to deliver safe, clean drinking water to those most in need.

  • To support sustainable development overseas, protect public health, encourage responsible growth, and minimize the impact of population growth on the environment and the world population as a whole.

  • To support joint U.S. and foreign economic development by establishing partnerships abroad.

AWWA is the authoritative resource for knowledge, information, and advocacy to improve the quality and supply of drinking water in North America and beyond. AWWA is the largest organization of water professionals in the world. AWWA advances public health, safety and welfare by uniting the efforts of the full spectrum of the drinking water community. Through our collective strength we become better stewards of water for the greatest good of the people and the environment.

Mr. Stahl wants help with SO2 tank:

At the Eugene plant we use one-ton cylinders of Cl2 and SO2 for chlorination and dechlorination, feeding liquid chemical into water-bath evaporators and the resulting gas through standard water injectors.

Now here's the strange doings: Our SO2 pressure usually runs from 20-40 PSI on the liquid chemical header. The other night a guy valved on a full cylinder of SO2 and saw two odd things. First, he noticed that the cylinder yoke valve, the pigtail, and the header itself were hot instead of cold (usually as the liquid chemical surges into an empty header the sudden evaporation cools the header). Second, the header pressure shot up to 75 PSI. Over the next several hours the pressure dropped to 65 PSI, but that is still much higher than our system has ever run on the SO2 side.

The evaporator temperature is normal. As far as we can tell the one-ton cylinder was not overfilled with SO2, and anyway I can't see how that would explain the sudden heating of the header. If there was water in the header then the heat of solution when the SO2 formed sulfuric acid dissolved in the water might explain the heat, but would that explain the persistent high pressure? And we've never gotten water in that header, to the best of our knowledge, let alone all the way to the yoke valve at the business end of the pigtail.

Anybody ever seen this kind of thing before?
