SYSTEM FOR WATER TREATMENT WITH OZONE

摘要

: A water treatment system having an apparatus (2) for the intensive pretreatment of the untreated water with ozone, having a downstream filter (3) with reducing action, and also having an apparatus (4) for the postdisinfection is improved in that the excess ozone which accumulates in the upper part (17) of the filter tank and which is added to the water during the pretreatment is removed anhydrously and fed into the apparatus for the posttreatment of the filtered water. The post-treatment takes place preferably in a retention vessel (4) filled with packing material (15) in which the water comes into contact with ozone by surface contact. The water level (24) is kept constant by regulating the gas discharge from the retention vessel (4). (Illustrated by drawing).
