West of Scotland Water (WoSW) awarded a contract, under competitive tender, for its first ultrafiltration plant to PCI-Water. This is the first installation in the United Kingdom using a hydranautics-based UltraBar system.
Small Groundwater Site Requires Metals Removal System
In the past, testing for arsenic in drinking water has been as difficult as removing it. A variety of test kits have appeared on the market deriving from the need for easier, cheaper and faster methods. These test kits rival both the accuracy and low detection ability of laboratory instrumentation.
Test strip technology advances make difficult arsenic detection a thing of the past.
Numerous facilities have invested in copper/silver disinfection systems to address the limits of traditional water treatment methods. It seems likely that, as bacterial populations develop resistance, many of these systems will become less effective through time.
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.
How to Select from Available Treatment Options
Carbon block is used in a wide variety of applications and performs a wider range of filtration tasks than other products. How carbon block is engineered will determine its use.
The Kenosha Water Utility treatment facility, located on the shores of Lake Michigan in Wisconsin, needed to upgrade its two plants to meet the expanding water needs of the community it services. Continuous microfiltration helped meet those needs.
The occurrence of Cryptosporidium parvum and other pathogens in water supplies poses a dangerous problem to the water industry and human health. Read about a new technology that is helping rid of this problem.
Escherichia coli, a.k.a. E. coli. A terrible, but familiar word to the public suggests sewage or animal waste contamination. E.
Recent outbreaks of E. coli have brought consumer’s attention to their drinking water. Understanding its source, regulations and prevention will be key to combating this waterborne illness
Recent television news acknowledging the methyl tertiary butyl ether (MTBE) problems has brought attention to this subject once again. In a one-on-one interview, Jack Hoffbuhr, executive director of the AWWA, discusses MTBE's effects, clean-up options and his opinion on television's attempt to inform consumers.
A new water disinfection system has been developed to inactivate Cryptosporidium oocysts and Giardia cysts in drinking water. The technology, known as the CID, inactivates these pathogenic waterborne microorganisms using enhanced ultraviolet (UV) irradiation technology without filtrate disposal, chemical addition or related hazardous by-products.
