For highly humified peat with high mineral content, the most effective solution is alkaline extraction (preferably with KOH) combined with process intensification using the GlobeCore AVS vortex layer device. AVS accelerates mass transfer and breaks agglomerates, allowing you to extract more humic carbon into the liquid phase without harsh temperatures or long processing times. After AVS, use early mineral removal (screen + hydrocyclone), followed by centrifugation and membrane concentration to retain maximum humic compounds in the final liquid extract.
