Community systems achieve arsenic removal well below new standard
Overview of offsite media regeneration certification
Using the scope of NSF/ANSI standards to determine the appropriate standard for the application
Understanding possible problems and access to spare parts is critical to UV system installation and maintenance
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.

Commercial POU installations improve drinking water quality in Grimes, Calif.
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.
Joint NSF/EPA study analyzes the feasibility of an economically sustainable POU/POE decentralized public water system
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.
