Use of zeolite in the International Space Station (ISS) cabin air purification system According to a publication on NASA’s website, zeolite is set to be used in the air purification system of the International Space Station (ISS). In this air purification system (CDRA), which is responsible for safety in the crew cabin, zeolite of varying particle sizes will be used in future to remove carbon dioxide. The cabin air passes through a layer of zeolite, to which water and carbon dioxide molecules are adsorbed, whilst all other gases pass through. The zeolite is reactivated after being heated and exposed to ... Read more

zeolite in hydroponics | Zeolife.gr Hydroponics is an ancient method of growing crops that takes place without soil or earth. Non-aquatic plants grow with their roots in a completely inorganic medium, where they are fed with a nutrient solution. Put simply, the plants grow in water to which the necessary nutrients have been added. The plants’ roots float in the water or on a substrate of ‘pebbles’ through which water constantly flows. In ancient Egypt, Mesopotamia, during the Aztec era, and even in the famous Hanging Gardens of Babylon, the method of hydroponics was used. In modern times, hydroponics is ... Read more

zeolites and their use in crop production – Dr Z. D. Zartaloudis zeolite is a mineral found in volcanic rocks, and possesses interesting properties such as high adsorption capacity and cation exchange capacity. Its crystalline structure is unique in that it cannot be destroyed under any circumstances. It is the only material that can be described as ‘permanently alive’. More specifically, it is a hydrated crystalline aluminosilicate mineral containing alkali cations, with an infinitely open, three-dimensional structure. It is capable of adsorbing and desorbing water and exchanging its structural cations without altering its crystalline structure. Furthermore, zeolites adsorb polar molecules with ... Read more
