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.
