Maltese desalination test-bed shows SalTec energy-recovery advantages
Throughout the desalination industry, plant operators are looking for long-term solutions with lower lifecycle cost because of the link between water costs and energy costs. In order to meet operators' demands and requirements, equipment manufacturers are investing considerable resources in the development of new technologies that will reduce energy costs. The Water Services Corporation in Malta is one example of a forward-looking operator of a seawater reverse-osmosis (SWRO) plant seeking to ensure the production of high-quality drinking water at an affordable price. Established in 1993 to produce and distribute potable water on the islands of Malta and Gozo, WSC has an annual production target of 35 million m to satisfy the needs of its 400,000 residents and in excess of one million tourists. With the drive to produce greater efficiencies and water quality WSC has taken an opportunity to investigate and monitor the potential of a new technology from KSB, the SalTec pressure boosting and energy recovery system. The SalTec DT pressure exchanger in combination with KSB's HGM RO high-pressure pump creates a highly attractive proposition for RO plant designers and operators. The SalTec DT system provides a nominal capacity of 250 m /h, giving it the capability to operate in plants with train sizes ranging between 4,400 m /d and 5,000 m /d of permeate at common recovery rates.

South Florida embraces desalination and water reuse for the future
The days of limitless and cheap water in South Florida are gone. Planning, investments in alternative water sources such as desalination and reuse, and conservation are required to secure reliability and sustainability of current and future water supplies. The South Florida Water Management District (SFWMD) is the oldest and largest of the five districts in Florida. The district's mission is to oversee the water resources in the southern half of the state by balancing and improving water quality, flood control, natural systems and water supply within a 16-county region. A key initiative is restoration of the Everglades, a vast wetlands and US national park. By augmenting supplies through alternative sources - including desalination of brackish and seawater, reclaimed water and reducing demand through year-round water conservation, the SFWMD hopes to continue quenching the thirst for a renewed environment and an ever-growing population. Realizing that water desalination using reverse osmosis is energy-intensive, the district also supports studies and projects that use renewable energy to reduce the carbon footprint, operate more efficiently to reduce water use, and manage concentrate to protect the environment. To encourage diversification of water resources, public utilities that use reclaimed water for outdoor irrigation are exempt from water-shortage restrictions. This article appeared in the February/March 2009 issue of D&WR magazine.
