They are also called point-of-use water treatment systems and field water disinfection techniques. Techniques include heat (including boiling), filtration, activated charcoal adsorption, chemical disinfection (e.g. chlorination , iodine, ozonation , etc.), ultraviolet purification (including sodis ), distillation (including solar distillation ...
Basically, iodine number is a measure of the iodine adsorbed in the pores and, as such, is an indication of the pore volume available in the activated carbon of interest. Typically, water-treatment carbons have iodine numbers ranging from 600 to 1100. Frequently, this parameter is used to determine the degree of exhaustion of a carbon in use.
In water systems subject to heating hardness salts can be deposited as the decomposition of bicarbonate ions creates carbonate ions that precipitate out of solution. Water with high concentrations of hardness salts can be treated with soda ash (sodium carbonate) which precipitates out the excess salts, through the common-ion effect , producing ...
Point of use water filters are used in individual houses or offices to provide filtration of potable water close to the point of consumption. [1] The related topic, point-of-use water treatment describes full-scale water treatment options and technologies designed to serve communities when municipal water treatment fails or is unavailable.
Solar water disinfection (SODIS) application in Indonesia using clear polyethylene terephthalate (PET) plastic beverage bottles. Solar water disinfection, in short SODIS, is a type of portable water purification that uses solar energy to make biologically-contaminated (e.g. bacteria, viruses, protozoa and worms) water safe to drink.
