Ozone improves ceramic membrane use for wastewater reclamation

Ceramic membranes have been used in the industrial production of beer, wine and cheese. One of the reasons for this use is the narrow pore size distribution, where careful separation of different size compounds can be achieved. Outside of Japan, the use of ceramic membranes has been almost non-existent for municipal drinking-water systems. The slow adoption of this technology is largely the result of a perception by many that the costs are significantly higher. While the capital costs may be higher, the whole life cycle costs may not be, due to extended membrane life and more reliable operation. Most water reuse today takes the form of indirect potable reuse. These schemes frequently consist of several steps including physical and chemical disinfection and advanced oxidation. They have the disadvantage of high cost and often poor membrane fluxes due to the nature of the wastewater being treated. The study outlined in this article is preliminary, but shows that ozone in conjunction with ceramic membranes for water-reuse applications has many advantages when disinfection and advanced oxidation is required. As opposed to polymeric membrane systems that cannot tolerate ozone, ceramic membranes in conjunction with ozone can achieve multiple key objectives in one step. This article appeared in the May/June issue of D&WR magazine.

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.
