A study published as part of the EPA's Environmental Technology Verification (ETV) Program verifies the performance of a Fyne Process membrane filtration plant tested on high organic-laden surface water in Barrow, Ark. The plant was able to remove significant levels of organics--precursors to disinfection byproducts such as trihalomethanes (THM) and haloacetic acids (HAA)--producing water that easily met the disinfection byproduct standards set by the EPA's stringent Stage 1 D/DBP Rule.
Faucets for point-of-use (POU) water treatment systems must combine an attractive, contemporary appearance with materials that ensure safety and purity. POU faucets and systems are becoming increasingly important to help meet consumer demands for safe, high-quality drinking water. It is estimated that by 2020 almost every household will have a POU or point-of-entry (POE) water treatment system.
When applying zinc metal to steel handrail tubing for corrosion protection, batch hot-dip galvanizing and in-line, continuous galvanizing are the two most common methods. Understanding the metallurgy, bond strength, corrosion mechanisms and testing of these two galvanizing methods may lead to better design decisions for particular applications.

Basic water chemistry, terminology and applications can be very complicated and not seem so basic to individuals without a chemistry background. This series of articles will help shed light on the chemistry of water and the mysteries that it can contain, plus explain the technologies used to treat water so the purchaser can make an educated attempt to find the right solution for a particular application. There are no cut-and-dry formulas for water treatment and certainly no cure-all for every application or problem, but with an understanding of how water works and the technologies developed to treat water, a person can utilize his resources to come up with solutions for his particular need or application.
Brushing Up on Water Chemistry 101
Dealers of drinking water treatment systems today enjoy a growing market of opportunity. However, accompanying this growth is increasing competition, a tightening economy and a far more informed consumer. All of these require dealers to find better ways to differentiate their products and services.
A presentation supported by third-party testing and certification will bring peace of mind to the buyer and dealers closer to the sale.
As the POU/POE water treatment industry progresses to new levels and meets new challenges, issues regarding regulations and standards continually arise. As the industry waits for the EPA and U.S. government to finalize regulations, the industry is forced to ride out the MCL changes, rule withdrawals and estimated costs that each proposal brings. Listed here is a review of regulation changes the industry has seen in the last year and a brief look at which ones to watch for in the future.
Government Regulations and Safe Drinking Water Act Updates
On June 22, 2000, the U.S. Environmental Protection Agency (EPA) announced a proposed rule that would lower the current national primary drinking water standard for arsenic.
Addressing Arsenic Contamination Through Residential Drinking Water Treatment
As Dotcom companies come and go faster than we can click the mouse to catch them, more and more employees of these companies are looking for more than just good pay — they seek what will benefit them in the future and, likely, at other companies.
The rapid changes in technology are so prolific that it has forced us to become life-long learners. Rather than a rigidly structured process, learning is becoming a self-directed process.
In the past year, manufacturers have begun advising consumers that the replacement elements they produce fit other manufacturers housings or pitchers and infer that the hybrid system will perform as well as the original system. This, in NSF's opinion, is not truthful information to the consumer.One of the main purposes of the NSF International Drinking Water Treatment Unit Certification Program is to assure that a drinking water treatment system performs in the marketplace as tested and certified by NSF.
The NSF Certification claims for a water filtration system are null and void when a component is placed in another housing
