DETAILED DESCRIPTION

(8) Referring to drawings shown, this application refers to CONSTRUCTIVE METHOD AND OPERATIONAL PROCESS FOR CREATION OF ARTIFICIAL BEACHES. SUITABLE FOR BATHING, AROUND PLOTS OF LAND, more precisely, a constructive method and operational process for the creation of artificial beaches, suitable for bathing, around plots of land, which allows implementation of watercourse canals (1) for formation of isles (I) and/or peninsulas (P), comprising lots (L) of condominium and/or subdivision, with formation of artificial beaches (2) in perimeter of lots (L), watercourse canals (1) being proper for contemplation and bathing by condominium members and/or owners of subdivision.

(9) According to the constructive method, a main canal (1A) is excavated in closed loop, surrounding an entire block (Q) of lots (L), forming isles (I) and/or peninsulas (P) on banks of the main canal (1A) and secondary canals (1B) are excavated connecting the main canal (1A) of right to the main canal (1A) of left, to form isles (1) within block (Q) of lots (L).

(10) Preferably, if excavated soil of the main and secondary canals (1A and 1B) is adequate, it can be used for landfill and conformation of isles (1) and/or peninsulas (P), so that lots (L) that make up a subdivision are at higher elevation than excavated canals (1A and 1B).

(11) For waterproofing of the excavated main and secondary canals (1A and 1B), use of reinforced concrete, compacted clay soil, vinyl or plastic blanket (3) is foreseen, which will ensure that water stored in the main and secondary canals (1A and 1B) does not contact groundwater table of site.

(12) Over waterproofing (3) a layer of white or clear sand (21) is provided to form beaches (2) all over the main and secondary canals (1A and 1B) excavated, in addition to natural beach-like landscaping.

(13) For filling the main and secondary canals (1A and 1B) raw water (4) is collected from external water sources, of any nature (river, sea, lake, reservoir, etc.), including polluted water, through a pumping system or by gravity through piping or a connection canal (4A) which is then treated in a water treatment plant, by a high-performance flow flotation system (5), and sodium hypochlorite or other oxidizing agent is added in doses (22), making this treated water suitable for use by bathers.

(14) High-performance flow flotation system (5) includes application of coagulant (6) and flocculant (9) material in a watercourse; allowing downstream aggregation of suspended particles (7), defining larger flakes; subjecting these aggregated and larger particles downstream watercourse to at least one stage of dissolution and injection of microbubbles (8) of air or concentrated oxygen, causing flotation of aggregated particles; allowing downstream agglomeration (10) of floated material to occur on the water surface, which is removed from the watercourse by a floating dredging wheel (11); and as a last step of treatment, sodium hypochlorite or other oxidizing agent (22) is added in doses into treated water to ensure its disinfection and use for bathing. This treatment process is efficient in removing more than 95% of pollutants, also eliminating odor and releasing oxygen-saturated water, without being necessary to perform any type of water filtration process, which would greatly increase costs of operation and be unfeasible because of sand on the canal bottom.

(15) The treatment canal does not have any physical division or space between treatment stages, creating a continuous water treatment canal (24), ensuring maximum treatment capacity, increasing hydraulic detention time and consequently greater treatment capacity, thus reducing implementation and operation costs.

(16) Coagulation (6) and flocculation (9) stages are performed in continuous flow (12) of the treatment canal with accurate control of power applied in coagulation (6) and flocculation (9) by injection (8) of thin, medium and thick bubbles with variable and controlled intensity, which increases efficiency of coagulant mixture and subsequent mixture of flocculant in water, and formation of clots (6) and later, formation of flakes (9), thus reducing consumption of these chemicals, and consequently their stock volume and cost of operation.

(17) For continuous treatment of water in the main and secondary canals (1A and 1B), water will be collected (4B) from the main and secondary canals, and routed upstream to the water treatment station (5), to be treated with water collected from an external water source (4), to keep water quality levels of the mentioned canals of block (Q) of lots (L).

(18) Main canal (1A) is provided with an overflow pipe or canal (13), used to equalize water level in the main and secondary canals (1A and 1B), and by this pipe or overflow canal (13), excess water already treated is returned to the external water source, avoiding overflow of the main and secondary canals (1A and 1B). This overflow pipe or canal (13) is also designed to completely empty the main and secondary canals (1A and 1B) to allow them to be completely emptied and maintained.

(19) To assist constant circulation and create water flow through the main and secondary canals (1A and 1B) of block (Q) of the condominium and/or subdivision, one or more axial pumping systems (14) of high flow and low pressure are provided, and pumping systems (14) are housed inside protection grids (15) and hidden at the bottom or banks of the canal (1), to avoid contact of bathers and consequent accidents.

(20) Axial pumping system (14) can also perform add doses (22) of sodium hypochlorite or another oxidizing agent, ensuring adequate distribution all over main and secondary canals (1A and 1B) of block (Q).

(21) Main and secondary canals (1A and 1B) also provide installation, in the same site where the axial pumping system is located (14), of another mechanical or hydraulic pulse equipment (16), which is also housed inside protection grids (15) and hidden in banks of the canal (1), which, by releasing a shock wave (17), creates waves or ripples (18) in the main and secondary canals (1A and 1B) of the block (Q) of the condominium and/or subdivision.

(22) Mechanical or hydraulic pulse equipment (16) also helps in cleaning of the watercourse canal (1A and 1B), once the shock wave (17) released by the mechanical or hydraulic pulse (16) in the watercourse, causes any residues eventually decanted in the main and secondary canals (1A and 1B), to move and circulate and they can be captured (4B) for continuous treatment in the water treatment station by flotation (5).

(23) An overflow system (13) is also provided for treated water, from the main and secondary canals (1A and 1B) of the block (Q) of the condominium and/or subdivision, returning to the external water source, allowing complete drainage of water from the main and secondary canals (1A and 1B) and occasional cleaning of the bottom of the main and secondary canals (1A and 1B), using minimum amount of new external water, only to replace evaporation loss.

(24) Water level in the main and secondary canals (1A and 1B) of the block (Q) of the condominium and/or subdivision is managed by equalization of a catchment (4) of raw water from the external water source, with drainage of water by the overflow system (13) of internal water already treated, keeping a constant water level in the main and secondary canals (1A and 1B).

(25) For access of condominium and/or subdivision members to the block (Q), construction of bridges, passageways or crossings (19) over the main canal (1A) is foreseen, so as not to prevent free circulation of water flow (12A).

(26) External and internal roads (19A) are provided for circulation of cars on isles (I) or peninsulas (P) and one or more pedestrian streets (23) connecting isles (I) of the condominium and/or subdivision, from one end to other.

(27) Installation of one or more common recreational areas (24) of the condominium and/or subdivision is also planned.
