Color Remediation Chromatography Tech
There are several methods to approach color remediation with the most common being Adsorbent Filtration.
A column is packed with adsorbent media in proportion to the amount of oil being remediated. The oil is then dissolved in a non-polar solvent and run through the column of adsorbents. Depending on the adsorbents used, a variety of contaminants can be remediated.
Another common method of Color Remediation is Nano-Filtration Membranes.
Nan-Filtration membranes are a size exclusion method of remediation. Based on the pore size of the membrane, only molecules below that size can pass through. Since color contaminants, fats, and lipids are bigger molecules than cannabinoids they can be excluded while the cannabinoids can pass through freely. There is a much higher startup cost with membranes, but they require significantly less labor and time.
