The idea behind using GAC as a filter for biological material is based on its porosity and surface properties. Molecules from viruses to macromolecules to polycellular organisms are able to be trapped by GAC. But using GAC with biological molecules supported on it can remove conventional pollutants; viruses can be immobilised via a GAC and metal combination.
In the second in a five part series on the applications of activated carbon, the use of activated carbon to sequester heavy metals is examined. Heavy metals, for example cadmium and lead, are notoriously difficult to remove from solution and there are serious consequences if these make their way into water courses, drinking water or the sea. Activated carbon is part of the solution.
The first in a five part series on the applications of activated carbon, desalination is discussed here. With certain parts of the world consistently suffering from a poor potable water supply, the concept of desalination is appealing. Contemporary methods for removing the salt from seawater are expensive and energy intensive. The use of activated carbon may help alleviate some of these concerns.
Maddox is a catalyst produced from pure manganese ore that has been treated in a special furnace using proprietary techniques.
Some important properties of feldspar is the alumina and alkali content. Thus they have many applications in the paint, glass, and ceramic industries.
Desalination requires a lot of contaminants to be removed for it to be a viable process. Anthracite and process expanded clay can provide effective, long-term filtration solutions.
In this article, we will go over some of the common water filtration media and find out how they filter water to make it clean and safe for consumption.
Magnetite has many applications beyond iron and steel, here we look at its applications in coatings, pigments and dyes, recording media and in the Fischer-Tropsch process.
Magnetite is a common ore of iron, is the most magnetic of all the naturally occurring minerals in nature and has many uses and applications beyond the production of iron and steel.
We will explore the ways in which anthracite can be used to render salinated water potable and drinkable.
