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.

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.

Hydrogen sulfide is a common component in wastewater treatment plant off-gases (e.g., biogas) and waste gases from certain industrial processes. It is highly toxic and odorous. Therefore, its release into the atmosphere is regulated. In addition, it is very corrosive, which can result in costly damage to equipment and piping systems used in biogas handling. Several technologies exist for removing H2S from gas streams, but many suffer from drawbacks such as insufficient removals, complexity or high cost.
