Utilization of Titanium Oxide in filters for Clay Water Pots

This involves modification of Titanium Oxide by incorporating other metals into it. Taking small portion of the mixed compound and incorporating it to the clay, molding a pot like filter out of it, drying and burning at high degree. When cool the clay pot is placed on top of a another pot or bucket and both placed in the sun where the energy released kills the micro-organisms or reduces the metal ions.Titanium oxide acts ...more »

Use of a clay-polymer nanocomposite for water filtration

This is a project I am currently working on for my Chemistry Honours degree. Using a clay-polymer nanocomposite for water filtration. It is well known that clay is a very abundant material especially in Africa, and it is also very cheap commercially.In comparison to activated carbon, clay is actually 20 times cheaper. Naturally clays are non-toxic and have very good adsorbent properties because of their already existing ...more »

Water filter solution

In Relation to most filtration methods, water is carefully introduced to one side of the filter, which acts to block the passage of anything larger than the pore size, typically bacteria, protozoa, and microbial cysts are removed Ceramic water filters may be treated with silver in a form that will not leach away. The silver helps to kill or incapacitate bacteria and prevent the growth of mold and algae in the body of ...more »
