Diffusion model of washing process

The paper contents the optimization of the washing processes which are characterized by large consumption of water and electrical energy mainly. For this reason is very important deal with them. For the optimization process of washing it is possible to set up an access of the indirect modeling that is based on make-up of mathematical models coming out of study of the physical operation mechanism. The process is diffusion character it is characterized by the value of diffusion effective coefficient and so called structure power of the removing item to the solid phase. The mentioned parameters belong to input data that are important for the automatic control of washing process
