Sustainable method and system for treating water bodies affected by bacteria and microalgae at low cost
First Claim
1. A sustainable method for treating and maintaining a body of water affected by bacteria and microalgae at low cost by filtering a small fraction of the total volume of the body of water, the method comprising:
- a. Collecting water with a concentration of total dissolved solids (TDS) of up to 50,000 ppm;
b. Storing said water in at least one container, wherein said container has a bottom surface able to be thoroughly cleaned by a non-intrusive mobile suction means;
c. Limiting the density of bathers up to 0.05 bathers per cubic meter in said water contained in said container;
d. During a 7 day interval, treating said water in said container for a total oxidation reduction potential (ORP) treatment time during the interval by periodically adding disinfectant agents to said water to establish an ORP of about 500 mV, wherein said total ORP treatment during the interval is dependent on temperature of said water being treated and comprises a minimum period of about 1 hour for each degree Celsius (°
C.) of water temperature up to a maximum temperature of 45°
C.;
e. Activating the following processes through a coordination means to purify said water and eliminate solids from said water by filtering only a small fraction of the total volume of said water in said container, wherein said coordination means receives information regarding water quality parameters controlled by said coordination means and activates processes i, ii, and iii to adjust said parameters within their limits;
i. Suctioning a portion of said water containing settled solids with a mobile suction means to prevent the thickness of settled material from exceeding an average of 3 mm;
ii. Filtering the portion of said water suctioned by the mobile suction means; and
iii. Returning the filtered water to said container.

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. The methods and system of the present invention can be used to treat recreational water bodies affected by bacteria and microalgae and provide sustainable methods for producing water that complies with bacteriological and physicochemical requirements for recreational water, as set forth by governmental regulatory agencies such as the Environmental Protection Agency (EPA), for bathing with full body contact.
