Portable water purification devices – better described as point-of-use (POU) water treatment systems and field water disinfection techniques – are self-contained, hand-carried units used by recreational enthusiasts, military personnel, survivalists, and others for water purification when they need to obtain drinking water from untreated sources (e.g. rivers, lakes, groundwater etc.). These personal devices and methods attempt to render water potable (i.e. safe and palatable for drinking purposes - without disease-causing pathogens).Techniques include heat (including boiling), filtration, activated charcoal absorption, chemical disinfection (e.g chlorine, iodine, ozone, etc.), ultraviolet purification (including SODIS), distillation (including solar distillation), and flocculation. Often these are used in combination.Many commercial portable water purification systems or chemical additives are available for hiking, camping, and other travel in remote areas.
