Let's take a closer look at the technology and operation of ion exchange resins and processes used today in industrial water treatment systems.
In 2001, the Minnesota State Fair built a 50-foot by 80-foot state-of-the-art barn, which would feature cows, pigs and lambs. The Miracle of Birth Center was built to reflect modern animal production practices in the existing Children's Barnyard at the fairgrounds. Pregnant cows, pigs and lambs were transported from out state Minnesota for the special birthing exhibit in the Children's Barnyard.

In response to the increasing number of outbreaks in U.S. hospitals, Pall Corp. introduced a water filter that prevents the spread of Legionella and other potentially lethal pathogens
Presence of the bacteria Legionella pneumophilia in hospitals and nursing homes in the U.S. and Europe has been detected at an alarming rate. Contaminated water has frequently been found to be the source. In response to the increasing number of outbreaks in U.S. hospitals, Pall Corp. introduced the Pall AquaSafe water filter.
A wide range of technologies, some new and some more traditional, is being marketed and applied for arsenic treatment. Each of these technologies has specific properties impacting its suitability for any particular scale of application. While rare, the ability of a single water treatment technology to perform effectively across many treatment platforms is not unique.
Cross-platform viability of treatment technologies
In February, NSF International arranged for many experts to cover the issues and facets of point-of-use and point-of-entry (POU/POE), how they can be used for PWS compliance and other opportunities for the manufacturers and users. This article is intended to provide opinions and a broad conference overview.
As populations grow, as urban, suburban and ex-urban areas expand, demand for water increases and safety standards rise. An effective and creative way to deal with problems of growth and resource management might just be to think small. A case in point is the Olivenhain Municipal Water District's (OMWD) treatment facility in San Diego County, California.
A combination of increasing arsenic levels from the new well and the lowering of the MCL to 10 ppb has the water company concerned about meeting the new arsenic standards.

The George Warren Fuller Award is presented annually to one member of each section of the American Water Works Association (AWWA). It is based on recommendations from the sections for distinguished service in the water supply field and "in commemoration of the sound engineering skill, the brilliant diplomatic talent and constructive leadership talent" that characterized Fuller's life.
The City of Chesapeake, Va. is located in the region called Hampton Roads, the 27th largest metro area in the country with more than 1.5 million residents. With an annual rainfall of approximately 48", its designers must contend with the prospects of determining where 294 billion gallons of water will go. A large share of this rainfall will find its way into the storm sewers. Last year, the City Council appropriated an extra $467,600 for contract cave-in repairs. The City of Chesapeake has recognized this problem and is developing a program to address it.
