About Carbon Post Filtration

Steam distillation effectively removes a wide spectrum of contaminants. The boiling process kills waterborne microorganisms like bacteria, cysts and viruses. When steam rises it leaves behind dead microbes, dissolved solids, salts, and heavy metals. While most contaminants are effectively removed by steam distillation, the carbon post filter is the preferred treatment for volatile organic compounds (VOCs) such as chlorine and chloroform.

Technically speaking, activated carbon undergoes and "activation" process that creates an internal network of very fine pores. This enables it to attract microscopic contaminant molecules and increase the absorption capacity to effectively act as a final "polishing" agent after the steam distillation process.

What is carbon post filtration?

Post filtration is used as a final treatment to effectively remove volatile organic compounds (VOCs). It significantly reduces trihalomethanes, synthetic organic compounds such as pesticides and hydrocarbons, and petrochemical byproducts such as benzene, toluene, and methyl tertiary-butyl ether (MTBE).

Why is posttreatment needed?

To remove contaminants that may carry across in the steam. Carbon posttreatment ensures high purity water after the distillation process is completed.

What type of carbon is used?

The disposable filter contains granular activated carbon (GAC) produced from organic coconut shell. Activation reorders the carbon atoms to produce an extremely porous structure with a much larger surface area. This network of very fine pores is extremely effective at trapping contaminant molecules.

How does the filter work?

Organic GAC works by process of aeration and adsorption (versus absorption). Absorption: needs to soak up. GAC does not absorb. Adsorption: means to it here to or on. GAC takes up contaminants by attractive (magnetic) forces.
