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.

New recovery technologies can minimize concentrate volumes

Several emerging technologies show potential to enhance recovery rates during desalination of brackish water. These processes include emerging approaches for concentrate treatment and new desalination technologies. Emerging concentrate treatment technologies that aim to enhance recovery and thus minimize concentrate include physical-chemical or biological treatment of concentrate followed by further reverse-osmosis (RO) treatment; new RO methods based on softening pretreatment and pH control to result in a high-efficiency system; a new RO separator that uses vibration shear force; and seeded slurry processes combined with RO to remove scaling compounds in a controlled fashion. Some of these emerging technologies could be applied at full-scale as the primary desalting step in non-municipal applications. For municipal applications, however, these technologies would likely be most cost-competitive when used to treat the concentrate from a conventional RO system, which is being used as the primary desalting step. These emerging technologies have the potential to enhance recovery rates by about 10% or more, thus resulting in significant concentrate minimization. Additional research, both at the fundamental and applied levels, will be important and beneficial to develop, optimize, and implement practical solutions to minimize concentrate. The full article first appeared in the November/December 2008 issue of D&WR magazine
