Ultraviolet Dechlorination Technology

At the Procter & Gamble manufacturing plant in Greensboro, N.C., an Aquionics ultraviolet (UV) dechlorination unit was installed before two banks of reverse osmosis (RO) membranes. Trials that ran soon after the UV system’s installation showed a dramatic reduction in the RO membrane wash frequency—down from an average of eight cleanings per month to only two per month.

Using Advanced Adsorptive Media for Arsenic Treatment

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.

Making the Filtration Buying Process Easier for Your Customers

If you’ve seen it once, you’ve seen it a hundred times — customers who come to you looking for a home filtration system, unaware of what their specific needs are. While many consumers simply want a system that improves their water’s taste and aesthetic qualities, the majority are looking for a product that will make their water healthier. But as you know, “healthier” is a subjective term, and without knowing the issues that are present in the customer’s water, providing them with a system that fits their needs isn’t very easy to do.
