Water and Air UV Treatment

UV is an accepted and rapidly growing technology for treating wastewater in the United States. In Europe, it commonly is used as a primary disinfectant in municipal drinking water systems. Other applications include food and beverage, pharmaceutical, semiconductor and power generation. This article will discuss three other commercially successful and growing applications.

POU Options for Arsenic

The topic of arsenic has received a lot of press coverage this year, ever since the Bush administration halted the EPA’s newly issued maximum contaminant level (MCL) of 10 parts per billion (ppb). Since then, the MCL was reinstated back to 50 ppb and further discussions and studies have continued. This article will discuss some of these updates.

The State of Regulations

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.
