Contaminant Reduction Testing: POE vs. POU

There are obvious differences between point-of-use (POU) and point-of-entry (POE) water treatment products. For example, POE treats water for the whole house, or a majority of the house, while POU treats water for a single tap or multiple taps, but not a majority of the house. For POE systems, pressure drop is a major concern because most of the household plumbing is downstream of the system.

New Arsenic MCL: The Dealer’s Perspective

Water Quality Products asked Frank DeSilva, national sales manager for ResinTech, Inc. to share his thoughts on the potential market the new arsenic rule may create for POU/POE dealers.

The new arsenic rule takes effect on Jan. 23, 2006. The U.S. Environmental Protection Agency (EPA) has set the new arsenic limit to 10 parts per billion (ppb), down from the previous limit of 50 ppb. Municipal water utilities are the major water treatment facilities that are faced with these changes. All purveyors of drinking water are affected, including public and private systems.

Membrane Filtration

As the nation’s population continues to grow, the associated use of chemical products and waste generation rises accordingly. As a result, an increasing variety of contaminants are regularly released into the nation’s water sources, eventually making their way into the drinking water supply.
