industrial news Preferred bidder of Algerian desalination plant named
BAF technology may reduce plant upgrade costs
Algerian Energy Company (AEC) has declared Ionics Inc of Watertown, Massachusetts, USA, as the selected bidder for a seawater desalination plant located near Algiers. Ionics and AEC will form a joint-project company to finance, build and operate the plant, with the former owning a majority interest. The projected US$225 million capital investment will be financed by a combination of equity and non-recourse debt. The desalination plant will have a capacity of 200 000 m3 of drinking water a day. Ionics will design and supply the seawater reverse osmosis desalination system, and will operate the facility over a 25-year contract period. The company claims that the plant will be the largest membrane desalination facility in Africa and one of the largest in the world. In other news, Ionics has signed a marketing and licence agreement with Japan’s Mitsubishi Rayon. According to the company, the multi-year agreement gives it an exclusive license to use Sterapore hollow fibre membranes in membrane bioreactor (MBR) applications in the Americas. A number of MBR systems incorporating these membranes are already in commercial operation in the Pacific Northwest, New England and in the Caribbean.
An relatively new technology, known as biological aerated filtration (BAF), is being considered as a way of upgrading the Point Loma wastewater treatment plant in San Diego, California, USA, to federal standards at a fraction of the cost of conventional sewage treatment. San Diego wastewater officials say it has the potential to save more than US$1 billion if the city ever had to upgrade the wastewater facility, which is its main processing plant. Beginning in January 2004, the officials want to conduct a US$1.7 million test of the filtration technology. This is intended to demonstrate how effective the technology is in treating the region’s sewage. Point Loma plant handles 680 million litres of sewage on a daily basis. It currently uses a process called advanced primary treatment to remove 85% of the solids from the sewage before discharging the wastewater offshore. San Diego is one of only a handful of regions in the US that have a waiver from the US Environmental Protection Agency (EPA) allowing it to treat its sewage to a level that is less than the federal standard. To meet that standard, known as secondary treatment, it would have to remove 90% of the solids from its wastewater. The wastewater department estimates it would cost sewer customers $2 billion to upgrade to a conventional method of secondary treatment, called activated sludge. By contrast, the new technology of biological aerated filtration needs relatively little space, negating the expense of constructing another plant. The department estimates the cost of an upgrade to secondary treatment using this new method will be $500 million.

Chinese plant uses WAO to treat problem waste USFilter, Zimpro Products is supplying a Zimpro® wet air oxidation (WAO) unit for ethylene spent caustic treatment to the Shanghai SECCO Petrochemical Co’s industrial wastewater treatment plant in Caojing, China. This is said to be the first Zimpro WAO unit installed in China for ethylene spent caustic. According to USFilter, the use of WAO technology will help SECCO alleviate two problems that are frequently associated with ethylene spent caustic, namely disposal and odour. It says that its WAO technology destroys odorous sulphides and allows acid neutralization of the spent caustic, which can then be discharged and dealt with by conventional biological treatment. ABB Lummus Global and Sinopec Engineering are providing engineering and procurement services for the new petrochemical complex. ABB has recently worked with USFilter, Zimpro Products on other projects using WAO technology. WAO is widely used to treat both refinery-spent caustic and ethylene caustic. In recent years, Zimpro Products has supplied more than 20 WAO systems for spent caustic treatment. Contact: USFilter, Zimpro Products, 301 West Military Road, Rothchild, WI 54474, USA.
