Particle separation is a key process in water and wastewater treatment, with a vital role in meeting water quality standards around the world, and encompassing a very wide range of particulates in widely varying contexts. Recent research has extended the field of application of particle separation to include the sub-micron scale, but innovative treatments are being developed across the board. All these aspects were addressed at the Particle Separation 2005 conference.
　　This issue contains 31 papers selected after full peer review that embody the latest advances in particle separation as applied to wastewater treatment technologies.
