Water reuse continues to rise as demand for fresh water supplies increases worldwide. By recycling and reusing treated wastewater, communities and industries can save on the costs of clean water, ensure adequate supplies and help to preserve a diminishing natural resource. The increase in water reuse has been driven largely by innovative treatment technologies that are both cost effective and reliable in removing harmful bacteria and pathogens. Membrane technology offers several varied applications covering many aspects of the textile processing. These applications are unique because they provide a return on investment (ROI) while abating a water pollution problem. This paper presents descriptions of some of the uses membranes have in textile operations and their benefits, it also delivers a scientific and technical overview and useful information to scientists and engineers who work in this field.
