Method for treating waste water
View Patent ↗An apparatus and method for passively generating a current flow in a body of water is disclosed. The passive water circulating apparatus has an aeration plate having a central opening; a plurality of flotation members joined to the aeration plate, the plurality of flotation members being adapted and disposed for maintaining buoyancy of the aeration plate above a water surface; an uplift tube member having a central orifice in fluid communication with the central opening of the aeration plate; a concentrator member disposed at an end of the uplift tube opposite the aeration plate, the concentrator member having a bottom opening in fluid communication with an upper opening, the bottom opening being wider than the upper opening and the upper opening being connected to the uplift tube member; and a plurality of bio-substrates suspended from the concentrator member below the bottom opening, the plurality of bio-substrates providing a substrate for growth of microbes.
1. A method for passively generating current flow in a body of water, the method comprising:
promoting growth of microbes on a plurality of bio-substrates;
funneling waste gases produced by the microbes along a confined fluid path;
transporting water through the fluid path using the waste gases; and
releasing the waste gases and transported water at an opening of the confined fluid path located at or above a water surface.
2. The method as in claim 1 , wherein the microbes are grown below a thermocline layer.
3. The method as in claim 1 , further comprising supplementing the waste gases with mechanically-generated bubbles.
4. The method as in claim 1 , wherein the transported water is drawn from an area below a thermocline layer.
5. The method as in claim 1 , further comprising radiating the transported water for a defined distance parallel to the water surface before reintroducing the transported water into the body of water.
6. The method as in claim 5 , wherein the transported water is radiated across an aeration plate disposed at a top surface of the body of water.
