Abstract: A method and system for treating water, and using the treated water for the cooling of industrial processes is disclosed. The water is treated and stored in a large container or artificial lagoon, has high clarity and high microbiological quality. A system of the invention generally includes a containing means, such as a large container or artificial lagoon, a coordination means, a chemical application means, a mobile suction means, and a filtration means. The coordination means monitors and controls the processes in order to adjust water quality parameters within specified limits. The large container or artificial lagoon can act as a heat sink, absorbing waste heat from the industrial cooling process, thus creating thermal energy reservoirs in a sustainable manner, which can be later used for other purposes. The method and system can be used in any industrial cooling system with any type of water available, including fresh water, brackish water, and seawater.

Abstract: A sustainable method and system for treating and maintaining bodies of water at low cost for low density recreational use is disclosed. A system of the invention generally includes at least one containing means, at least one coordination means, at least one chemical application means, at least one non-intrusive mobile suction means, and at least one filtration means. The coordinating means can receive information regarding water quality parameters that are controlled, and can timely activate the processes necessary to adjust the water quality parameters within their respective limits. The disclosed methods and system filter only a small fraction of the total water volume, up to 200 times less per day than the flow filtered by conventional swimming pool filtration systems. The disclosed methods and system also use less chemicals, up to 100 times less than conventional swimming pool water treatment systems.

Abstract: A low cost method and system for treating water, which will be used in an industrial process, is provided. A system of the invention generally includes at least one containing means, at least one coordination means, at least one chemical application means, at least one mobile suction means, and at least one filtration means. The coordination means can control the necessary processes depending on the system needs (e.g., water quality or purity). The method and system of the invention purifies the water and eliminates suspended solids without the need of filtering the totality of the water volume, but only filtering a small fraction of up to 200 times less than the flow filtered by a conventional water treatment filtration system.

Abstract: A suction device is disclosed for thoroughly cleaning the a bottom surface of a structure, covered with a non-porous plastic liner, that contains a body of water larger than 15,000 m3 for recreational use, with color, transparency and cleanness characteristics similar to swimming pools or tropical seas, said device operating by suctioning impurities from the bottom surface by a pumping system of said the structure.

Abstract: The invention discloses a process to implement and maintain water bodies larger than 15,000 m3 for recreational use, which comprises the following steps: a.—providing a structure able to contain a large water body larger than 15,000 m3; b.—feeding the structure of step (a) with inlet water; c.—measuring water pH; d.—adding an oxidizing agent to the water contained in the structure of step (a), e.—adding a flocculating agent in concentrations within 0.02 and 1 ppm with maximal frequencies of 6 days and cleaning the bottom of the structure of step (a) with a suction device to remove precipitated impurities from the bottom of said structure, and; f.—generating a displacement of surface water containing impurities and surface oils by means of the injection of inlet water according to step (b), which generates said displacement in such a way to remove said surface water arranged in the structure of step (a), which together with step (e) replaces traditional filtering.

Abstract: The invention discloses a process to implement and maintain large water bodies with color, transparency, and cleanness characteristics similar to swimming pools or tropical seas, at low cost. The present invention also discloses a structure to contain large water bodies, comprising a system for the removal of impurities and surface oils by means of skimmers and a suction device to clean said structure.

Abstract: The invention discloses a process to implement and maintain water bodies larger than 15,000 m3 for recreational use, such as lakes or artificial lagoons, with excellent color, transparency and cleanness properties at low cost, which comprises the following steps: a.—providing a structure able to contain a large water body larger than 15,000 m3; 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, ideally it should be within a range lower than 7.8; d.—adding an oxidizing agent to the water contained in the structure of step (a), with which a 600 mV minimal ORP is controlled in water for a minimal period of 4 hours and in maximal cycles of 48 hours; e.—adding a flocculating agent in concentrations within 0.
