Recycling of Wash Water as a Way to Reduce the Environmental Load and Increase the Utilization Rate of Raw Materials

The problem of recovering the protein and other valuable components from wash water (low-concentrated suspensions) exists in almost all areas of the food industry. Research in this field is quite successful and is mainly based on the processes of evaporation, flotation, the use of force fields, and...
