Or forced (active) condensation using compressors or Peltier modules to cool ambient air
Fog harvesting systems include a vertical mesh. The size of the filaments, size of the holes between those filaments and mesh coating are critical factors to successfully harvest water
Water harvesting technologies
The use of Stabilized Oxygen is not as known as other chemicals.
Filtration
Natural (passive) condensation using thermal mass to cool down hot / humid air
Chemical Treatments
Dew Harvesting
Desiccation / evaporation
Ultraviolet lights
Ozone has great oxidative power and is very reactive to germs, viruses and microbes
Cooling condensation
Many chemicals can be used to kill organisms that are known to cause illnesses. Some more common than others:
- Iodine
- Hydrogen Peroxide
- Bleach (regular - highly diluted)
- and even wine...
Filtration
Activated Oxygen
Desalination
Other chemicals can create health problems if used for extended periods of time, whereas Stabilized Oxygen has no such undesirable effects. Additionally, it does not adversely affect the taste of the water as do chemical treatments.
In this process, water is first "absorbed" by a desiccant (silica gel, calcium oxide, molecular sieve, clay or brine). Once saturated, the desiccant is heated to release vapors. Vapors then condense on a cold surface to create water.
Depending on the desiccant used, water might need to be filtered or purified to remove any chemicals.
Many ideas were developed after studying a beetle that uses its abdomen to condense water and channel it to its head to sustain hot and dry desert conditions
Boiling water (sterilization) has been used for centuries, however, it is overkill. Pasteurization at lower temperatures has the same effect and takes less time.
Simple water Purification Systems
Pasteurization
Dew wells like this one above have existed for centuries and can be found in Europe, Asia and Africa.
