PROBLEM TO BE SOLVED: To provide a plant for treating water with ozone comprising a plurality of ozone generators and a plurality of contact aeration basins, characterized in that the qualities of the water treated in each basin are uniformized with one another.AMANO ATSUSHI...
With water scarcity intensifying, wastewater treatment and reuse are gaining popularity. But some methods for killing microbes in wastewater create disinfection byproducts (DBPs) that could be harmful to human health. Now researchers have found that ozone treatment and subsequent chlorination can convert ...
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 post-disinfection is improved in that the excess ozone which accumulates in the ...
