Abstract

A water treatment assembly receives a supply taken from surface water bearing a heavy load of algae. The novelty is that: (a) the assembly has a pre-treatment stage in which ozone is dissolved in the water, killing especially bacteria, viruses, algae and oxidising organic substances; (b) the ozone-treated water is surrendered in the next stage in which a flocculant is added; (c) the water with flocculant agent is discharged to a first filtration stage in which killed micro-organisms are removed, and in which the dissolved organic carbon is removed together with the impurities causing cloudiness; (d) the filtered water is discharged to a second flocculating stage and then a second filter stage removing the second-stage flocculant products; (e) the second-stage filtered water is subjected to oxidation in which residual organic substances are broken down, and (f) the water is passed through a final carbon granule filtration stage.
