Well-designed water distribution and cooling systems,
coupled with sound management and operational procedures, are essential to
control Legionella in industrial facilities—and a monitoring program
should not be considered as a replacement. However, most experts even those
ill-disposed towards routine Legionella monitoring, would agree that monitoring
should be considered if enough legionellosis risk factors apply to the system
in question. No management program, regardless of its treatment, maintenance or
monitoring components, can guarantee the absence of future legionellosis, but
prudent operational practices combined with ongoing review of risk factors will
allow facility managers to minimize exposure to Legionella and to its legal consequences.
Water specialists should make Legionella reduction a top priority
Recent market research showed that more than 73 percent of consumers prefer to consult with a water treatment professional when dealing with arsenic. Combining this inclination with the preference for the POE approach, the treatment professional has a unique opportunity to generate significant new revenue from POE sales with minimal upfront effort.
In Port Hueneme, California, a state-of-the-art desalination facility uses three brackish water desalination technologies: reverse osmosis (RO), nanofiltration (NF) and electrodialysis reversal (EDR), operated side-by-side to produce over three million gallons per day (mgd) of high quality drinking water. The Brackish Water Reclamation Demonstration Facility (BWRDF) is the cornerstone of the Port Hueneme Water Agency’s (PHWA) Water Quality Improvement Program. In addition to providing desalted water for local use, the BWRDF also serves as a full-scale research and demonstration facility.
Kaldnes North America, an Anglian Water Company, was chosen to supply the city of Broomfield, Colo., with the Moving Bed Biofilm Reactor (MBBR) process to treat its municipal wastewater.
Under the terms of the contract, Kaldnes will retrofit Broomfield's existing aerobic basins with Kaldnes media, an aeration grid system and sieve assemblies. In addition, there will be new construction for phosphorus and nitrate removal.

The patented combination of slowsand with nanofiltration offers benefits that merit considerable discussion. This combination successfully was piloted by the University of Arizona beginning in 1987.
Understanding and reacting to the performance of a reverse osmosis (RO) system is necessary for continued successful operation. It is this interaction that allows us to quickly and correctly identify and correct issues that may arise.
Tending to System Maintenance is Necessary for Successful Operation
To most people, water clarity is important, but the nautical
archaeologists at Texas A&M University know that to rebuild a 300-year-old
ship, it is essential. They needed filtration equipment that was up to the
The Belle, a small 17th-Century French frigate, was discovered in July 1995 in Matagorda Bay, Texas, in 12 feet of water. The delicate nature of the waterlogged wood meant it could not be allowed to dry out. The water storing the ship must be free of particulate, algae and bacteria and may contain only chemicals safe for the staff to work in. Water also must be kept particulate-free in order for the conservation solution to work properly.
Harmsco filters provide maximum performance for ship’s excavation.
If our water supplies actually do come under attack, the question remains: Is there any way for consumers to protect themselves? Unfortunately, it seems to be too early to tell, yet some companies are beginning to emerge with products that may be the answer.
Can POU/POE technology aid the war on bioterrorism?
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.
