Silicon’s Activated Carbon Powder
Activated Carbon is a Microporous material manufactured from carbonaceous raw material i.e. Wood, Coconut Shell, Rice Husk, etc. The activation process develops a myraid of pores of molecular dimensious within the carbon which together constitutes an enormous internal surface area. The carbon atoms at the internal surface of Activated Carbon exert an alfraction on the molecules of the surrounding gases and liquids. The Strength of this force is related to the molecular structure of the surrounding medium. This is the mechanism by which Activated Carbon can be used to remove different components from a mixture.
Activated carbons are used as purifying and decolouring agents in a wide range of process and they absorb between 10% to 90% of their own weight of impurities from aquereous solution. Activated Carbon is added to the process liquor in an agitated vessel and filtered off after the required contact time.
It is a mineral of vegetable origin. It represents the accumulation of an enormous number of fossil diatoms. Diatomite is called miraculous mineral because of its lightness, porosity and its uniquely honeycomberd structure which makes it an ideal filtering medium. And because of its inherent stability and the absence of most trace elements, Diatomite is ideal for use by processor who have very high purity requirements such as the food, beverages and pharmaceutical industries, etc.
Filtration using diatomite is a two step operation. First, a thin protective layer of filter aid, called the precoat, is built up on the filter septum by recirculating a filter aid slurry. After precoating, small amounts of filter aid (body feed) are regularly added to the liquid to be filtered. As filtering progresses, the filter aid, mixed with the suspended solids from the unfiltered liquid, is deposited on the precoat. Thus, a new filtering surface is continuously formed. The minute filter aid particles provide countless microscopic channels which entrap suspended impurities but allow liquid to pass through, without clogging.
