By Shannon Murphy There are a number of ways a manufacturer can get a product certified to an ANSI/NSF Drinking Water Treatment Unit (DWTU) Standard. Component manufacturers can get their products certified for material extraction and— in special cases like reverse osmosis (RO) membranes and bottled water applications —for reduction claims. (Bottled water applications are allowed a filter claim for removal of Cryptosporidium; but this is a special circumstance only available to bottled water applications.) These components can then be sold to system manufacturers as already meeting a portion of the requirements of the standard. System manufacturers can then use…

By Kelly A. Reynolds, Ph.D. Could microsporidia be the Cryptosporidium of the new millenium? This is the current question water quality researchers and public health officials are trying to answer. Recently, clinical researchers from the Hepatogastroenterology and AIDS Unit in Lyon, France, identified microsporidia as a causative agent in a waterborne outbreak during the summer of 1995.1 During this incident, 200 persons were infected; however, no fecal contamination of water was evident and no source was found before the outbreak ended. An epidemiological study of conditions surrounding the outbreak and individual risk factors showed that the major factor associated with…

By Dr. Henry Nowicki The 7th Annual International Activated Carbon Conference (IACC) week was held Sept. 13-17, 1999, in Pittsburgh, Pa. About 100 individuals participated as vendors, speakers and attendees. The event followed the same format as prior conferences. Early in the week, Dr. Milton Manes, professor emeritus at Ohio’s Kent State University, provided a two-day short course titled “Activated Carbon Adsorption: Principles and Practices,” and Wayne Schuliger, P.E., research and development director at TIGG Corp. in Bridgeville, Pa., provided a one-day short course “Design of Activated Carbon Process Systems.” These optional courses—available yearly—preceded the two-day conference, which started Sept.…

By Carlos David Mongollón A Solution for Materials Safety While the actual new millenium may be a year away, chronologically and for all practical purposes, the beginning of this month is the date that’ll be celebrated—and if you’re reading this, the world didn’t fall apart as some were predicting. Meanwhile, those in the POU/POE water treatment equipment industry have a major success to celebrate in the agreement by NSF International’s joint committees on Drinking Water Additives (DWA) and Drinking Water Treatment Units (DWTU) to use Standard 61 rules as an option for materials safety compliance. The DWA committee approved it…

By Steven Delgado, WC&P Associate Editor I suppose it could be said that much of this column’s space is very critical of websites, with no apparent favorites. Websites reviewed in the last year have included topics ranging from non-profit, fringe organizations to the trade association of our primary readership, the point-of-use/point-of-entry residential water treatment dealers. The reviews had a tendency to pick on slow, not updated or technically prehistoric websites, so I thought readers would like to hear some do’s and don’ts from someone besides myself. Stephanie Gallagher has been reviewing business websites since the Internet race really took off…

By Carlos David Mogollón, WC&P Executive Editor There are awards we may receive from an organization that we belong to, recognition from our peers for serving our career well and plaques, certificates and titles that may be conferred upon us that require little more than our presence once bestowed. Membership on the Technical Review Committee of Water Conditioning & Purification Magazine is not one of those. “Serving on WC&P’s Technical Review Committee is more than an honor—it’s a job as an active participant in molding the editorial tenor of the magazine,” said Sharon Peterson, president of Publicom Inc., publishers of…

By Jerry Bujaucius The Internet and the World Wide Web represent a set of potent tools to any business. What started as a research network to link together several universities, military organizations and research facilities has now developed into one of the most powerful and profound business tools in memory. NUA, an Internet strategy, research and development agency (http://www.nua.ie), predicted Internet usage worldwide would grow from 150 million users at the end of 1998 to 350 million by 2005. This market remains a potential windfall for the first mover within any industry, as exemplified by Amazon.com (books) and Egghead.com (software).…
