Description
| - Leather industry is a prominent producer of large amount of waste. Some of this waste, especially chrome-tanned waste, is classified as hazardous. Disposal of this waste in landfills is expensive and brings both health and environmental risks. However, this waste also represents interesting source of valuable raw materials and it is advantageous to search for possibilities of its processing. Two-step enzyme hydrolysis seems the most attractive processing technology so far; however, it is not completely zero-waste due to its by-product, so-called chromium sludge. Relatively high protein content in the sludge represents technological obstruction and limits its further treatment and applications. The paper focuses on deproteination (removal of proteins) of chromium cake through a combination of mathematical and experimental methods. Mathematical model has been proposed for desorption of the protein fraction into the washing bath for various soaking numbers and decantation washing. The reliability of the model to predict the course of the desorption process was evaluated by means of experimental desorption of the protein fraction into the washing solution. The results of mathematical modeling showed that appropriate choice of conditions can lead to practically total deproteination of chromium cake. The mathematical model also serves as a basis for optimization of the process.
