Sustainable system for treating water bodies affected by bacteria and microalgae at low cost
First Claim
1. A system 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 system comprising:
- a container for storing the body of water, the container having a volume greater than 50,000 m3 and comprising a membrane or liner for receiving settled particles that is fixed to a bottom surface of the container;
at least one feeding line of affluent water to the container;
a coordination means for maintaining the water in the container within predetermined water quality limits;
at least one chemical application means for applying or dispersing a disinfectant or antiscalant to the water in the container;
a mobile suction means for moving along the bottom of the container and suctioning a portion of the water from the bottom of the container containing settled particles;
a propelling means for moving the mobile suction means along the bottom of the container, the propelling means operatively coupled to the mobile suction means;
a filtration means having a capacity to filter up to about 2.5% of the total volume of the body of water in a 24 hour period for filtering the portion of water containing settled particles suctioned by the mobile suction means;
at least one collecting line coupled between the mobile suction means and the filtration means; and
a return line from the filtration means to the container;
wherein the coordination means is configured to receive information obtained by visual inspection, an empirical method, an algorithm, or a detector regarding the water quality parameters and control activation of the chemical application means, mobile suction means, and filtration means to adjust the water quality parameters within predetermined limits, the water quality parameters comprising oxidation reduction potential (ORP), temperature, and thickness of settled particles.

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.
