Verfahren zur Aufbereitung von Trinkwasser für den Verbrauch

摘要

The invention concerns a method of treating driking water in the following stages: suspended solids are removed by means of a microsieve with a mesh of less than 40 microns, the water is subsequently ozonized and/or chlorinated and the water is filtered through sand to remove finely particulate suspended matter. In order to be able to leave out or reduce the ozonization or chlorination stage, which requires expensive equipment, the sterilization is carried out as a last stage using a microfilter or microsieve with a mesh size of less than or equal to 3 microns. A microsieve of this kind is capable of retaining any coliform bacteria and faecal streptococci remaining in the treated drinking water.
