Recycling Lanolin from Tannery Wastewater by Mixed Flocculation and Extraction Processing
Using mixed flocculation and extraction method to recover the lanolin from Tannery Wastewater, and studied the process research. The result indicated that the recovery rate of lanolin can reached 92% by using aluminium sulfate (AS) and the polyacrylamide (PAM) mixed flocculation, hexane and cyclohexane mixed extraction. Comparing the main indexes and the infrared spectra of recycling lanolin with the industry level lanolin, the results indicated the main indexes of the recycling lanolin achieved the industry level standard, and both similar spectrogram showed the component and the structure of recycling lanolin are almost similar with industry level lanolin. Therefore the method used to deal with tannery wastewater recycling lanolin is practicable and effective.
