Abstract
The present invention relates to systems and related methods of water purification by distillation that will operate in a self-contained mode using a passive heat source, such as, without limitation, solar heat, air conditioning waste heat, or waste heat from the exhaust or cooling systems of an internal combustion engine, which may be used to desalinate sea water, saline water, or saline water containing contaminants. The present invention may also be used to distil sewage water, creek water, swamp water or water containing contaminants or used to cleanse or purify water contaminated with mud, chemicals, minerals, or bacteria in a local environment.

A water purification system comprising:
- an upside down U-tube vessel;
- a vent valve connected to the upside down U-tube vessel at the top of the upside down U-tube vessel;
- a water storage tank;
- a heater attached to a first column of the upside down U-tube vessel;
- a water exit line that is connected to a second column of the upside down U-tube vessel at the bottom of the second column of the upside down U-tube vessel;
- wherein a partial vacuum is generated at the U-tube vessel by keeping the U-tube at the height that is higher than a height at which atmospheric pressure can support the water to be purified;
- wherein a water inlet is connected to the first column of the upside down U-tube vessel at the point that is higher than the water level within the first column of the upside down U-tube vessel to supply water to be purified to the first column by using the partial vacuum created in the U-tube vessel.
A water purification system comprising:
- an evaporating chamber;
- a condensing chamber;
- a pipe for connecting the evaporating chamber to the condensing chamber;
- a source water inlet line;
- a vent valve connected to the top part of the evaporating chamber;
- a water exit line that is attached to the bottom of the condensing chamber;
- a heater attached to the evaporating chamber;
- wherein a partial vacuum is generated within the evaporating chamber by keeping the evaporating chamber at the height that is higher than height at which atmospheric pressure can support the water to be purified;
- wherein the source water inlet line is connected to the evaporator at a point that is above the water line in the evaporating chamber;
- wherein liquid is transferred within the system by using the partial vacuum created within the evaporating chamber.
A method for generating a partial vacuum within a water purification system including an upside down U-tube with a first column and a second column, a heater for heating the first column, a cooler for cooling the second column, a source water inlet line which is connected to the first column of the upside down U-tube vessel at the point that is higher than the water level within the first column of the upside down U-tube vessel, a water discharge line, a vent valve, the method for generating partial vacuum within the water purification system comprising the steps of:
- opening the vent valve;
- sinking an upside down U-tube vessel into a water source until it submerges into the water;
- closing the vent valve after the U-tube vessel is completely submerged into the water;
- raising the upside down U-tube vessel higher than 10 meters such that the water level remains at maximum level while a vacuum is created above it;
- and filling water into one end of the upside down U-tube vessel wherein the pumped water temperature and the water temperature in the U-tube vessel are the same.
