Abstract:
1. A process to implement and maintain water bodies larger than 15,000 m 3 for recreational use, including lakes and artificial lagoons with desirable color, transparency and cleanness properties, wherein the process comprises: (a) providing a structure with skimmers able to contain a large water body larger than 15,000 m (b) feeding the structure of step (a) with inlet water having iron and manganese levels lower than 1.5 ppm and turbidity lower than 5 NTU; (c) measuring water pH, wherein the pH is maintained no lower than 5 and no higher than 9; (d) adding an oxidizing agent to the water body contained in the structure of step (a), to maintain an oxidation-reduction potential (ORP) of at least 600 mV in the water body using a pulse of at least 4 hours within a 48 hour cycle; (e) adding a flocculating agent in concentrations within 0.02 and 1 ppm over a time period no greater than 6 days to precipitate impurities in the water to the bottom of the structure of step (a); (f) cleaning the bottom of the structure of step (a) with a movable suction device to remove the precipitated impurities from the bottom of said structure, together with the additional flocculants; and (g) generating a displacement of surface water containing impurities and surface oils by means of injection of inlet water according to step (b), which generates said displacement in such as way to remove said surface water using said skimmers provided in the structure of step (a), which together with step (f) replaces filtration to remove suspended debris from the water body.
