Metals Plant Needs High-Purity Water   Water Quality Products July 2003   Crown Solutions, Inc.
Dayton Progress Corp.'s focus has been on manufacturing metal punches, punch blanks and metal stamping tools. It also would take experienced water treatment professionals to ensure that the proper quality water was used in each process. That is why it relied on Crown Solutions, Inc. to manage the point-of-use (POU) and point-of-entry (POE) water treatment for each of its manufacturing processes that required water.

Research Racks Up Recognition Points for POU/POE   Water Quality Products June 2003   Wendi Hope King
Some really important research going on right now, which is critical for the point-of-use/point-of-entry (POU/POE) industry in order for POU/POE treatment to become an accepted practice for small public water system compliance. It seems as though we are closer than ever to finding acceptance in this arena.

Arsenic Treatment   Water Quality Products June 2003   Ley Hathcock, Ph.D., Rich Cavagnaro & Greg Gilles
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.

A Solid Future for POU Water Purification   Water Quality Products March 2003   Glenn Land, Aduk, Inc.
Point-of-use (POU) water purification has a solid future. The relatively new POU industry will have to shoulder tremendous responsibility. Serious issues of water quality as well as quantity are apparent. The right of every human to water must be proactively protected if an acceptable quality of life for future generations is to be reasonably assured. This will not happen until it becomes a high priority political issue.

Evaluation of a Chlorine Dioxide Secondary Disinfection System   Water Engineering & Management November 2002   Frank P. Sidari III and Jeanne VanBriesen, Ph.D.
Chlorine dioxide is not a new technology for public drinking water facilities or pulp and paper producers, but its use as a secondary treatment system for small-scale applications is new. Beyond the chemistry and microbiology, potential small-scale operators want answers to a few simple questions: Should I use it? How does it work? What extra work is it going to make for me?

Bottled Water vs. Tap   Water Quality Products October 2002   Nadia Abboud, Severn Trent Services
While both sides of the bottled/tap battle continue trying to inform and ultimately win the consumer over, a few facts cannot be overlooked. Regardless of how a consumer obtains drinking water, both bottled and tap must draw from the same available global freshwater sources. Despite the information with which consumers are presented, ultimately the decision is theirs. When purchasing bottled water, knowing what you are getting requires some research and understanding.

Using Advanced Adsorptive Media for Arsenic Treatment   Water Engineering & Management April 2002   Greg Gilles and Jennifer Mathis
On November 26, 2001, the new arsenic standard was signed into law—lowering the acceptable level for the contaminant from 50 parts per billion (ppb) to 10 ppb. Approximately 4,100 municipal water systems serving nearly 13 million people nationwide are affected by the law and are required to meet compliance by January 2006. According to the U.S. Environmental Protection Agency (EPA), 97 percent of these systems are small systems serving fewer than 10,000 people each. The economic impact on these small systems is likely to be large. However, there currently are options available to small municipalities that may be more affordable than central treatment.

POU Technology Demonstrates Effectiveness   Water Quality Products March 2002   By Jennifer Mathis, Apyron Technologies, Inc.
In March 2001, the U.S. Environmental Protection Agency (EPA) withdrew a proposal for a lower maximum contaminant level (MCL) for arsenic in drinking water that would bring the standard from 50 parts per billion (ppb) to 10 ppb. At that time, the EPA commissioned three studies to examine the benefits, costs and health effects associated with a lower standard for arsenic.

Officials Recognize POU Industry   Water Quality Products February 2002   Wendi Hope King
After the U.S. Environmental Protection Agency (EPA) finally announced the new maximum contaminant level (MCL) of 10 parts per billion (ppb) for arsenic, an estimated 4,000 community water systems are now left to take measures to lower their arsenic levels, which were previously at 50 ppb.
