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.

Combining Forward Osmosis with Reverse Osmosis

A combination of forward osmosis with reverse osmosis could facilitate the treatment of some high fouling wastewaters. The system uses brine to draw water from the wastewater without high pressure or turbulence. Key element is the membrane's ability to allow rapid passage of water without much internal concentration polarization. The diluted draw solution can then be desalinated by reverse osmosis. The Two-Way Osmosis or TWO system may also be usable in very remote areas, where seawater ponds can be built for evaporative recovery of salt. Catalyx is designing a pilot system (patent pending) to desalinate seawater without external electric power. This article was published in the May/June 2009 issue of Desalination & Water Reuse.

Possibilities for energy optimisation in design and operation of SWRO plants

Seawater desalination with reverse osmosis (SWRO) has taken a noteworthy upturn during recent years. One of the reasons for the success of the membrane process is its lower energy consumption in comparison with thermal desalination processes. The high-pressure RO desalination stage is undoubtedly the dominating energy consumer of an SWRO plant. Energy consumption of SWRO, despite its energy-recovery aspects, is also influenced by a huge number of additional factors. These are both of an external nature (eg, environmental conditions and stipulations), but are also determined by design and configuration of the plant. On the basis of an SWRO plant model, which covers the different pre-treatment and RO configurations and also the design with energy consumption of potabilisation and additional wastewater treatment and sludge dewatering facilities, the specific energy consumption of an SWRO and its subsystems has been determined in this article. Considering the various aspects to be taken into account for optimization of energy consumption in seawater reverse osmosis plants and the fact that in most cases these measures are offset by increases in capital costs for equipment or possibly also in chemical consumption, optimisation of the energy consumption of SWRO plants during planning and operation is a quite extensive and complicated matter and a demanding engineering task. This article is an expanded and updated version of the article published in the August/September issue of D&WR magazine.
