System for treating sewage or other fluids

DETAILED DESCRIPTION This patent combines sui generis use of natural forces to completely purify water by exposing it to a very large hydrophillic solid surface extending up from the contaminated water surface, over the edge of its container and down to a collector at a lower elevation.
An ultra-thin layer of water forms on the surface above the water due to physical intermolecular attraction between the water and the polar substrate, leaving contaminants in the container.
Depending on the molecular polarity and effective area of the substrate, this film can rise to a height of at least several inches.
If the surface curves horizontally, it advances even further, since attractive forces no longer must overcome gravity.
If it then turns downward, the film flows with increased velocity, indefinitely, with the assistance of gravity.
At the lower, distal end of the surface, still with the aid of gravity, the film can coalesce and pool to drip or run off the surface into the collector.
The film on the above-described inverted U-shaped surface acts as a nearly perfect elastomer.
If the weight of the film on the downward flowing leg of the inverted "U" running to the collector is greater than the weight of the connected film on the upward flowing leg rising from the contaminated water, it will create upward elastomeric tension and stretching of the film on the upward leg with a force overcoming gravity, thus drawing the film up and over the top of the inverted "U" onto the downward leg and down to the collector to be released by gravity into it.
This process continues automatically, transferring purified water to the collector at a velocity dependent on the difference in weight of the upward and downward legs of the film.
Velocity will slow, then stop, as the container empties.
As the stretched film flows over the surface, energy is lost to friction so that the distance of travel, or, the total length of the inverted "U" limits the velocity of flow.
A greater medium effective surface area holds a greater volume of flowing film for a greater total flow rate at any given velocity
