Deep processing of permeate after nano-filtration (nf) of milky whey

Abstract

The method of deep processing of nano-filtration permeate of milk whey is proposed and scientifically substantiated, using ozonation and electrodialysis processes. The ozonation station can remove up to 96 % of organic compounds of NF permeate, and the amount of dissolved ozone in this case should be 20...28 mg/dm3. This treatment allows us to fully utilize NF permeate in the future. It has been established that in order to achieve the posteffect of the impossibility of microflora in the ozone-treated nanofiltration permeate, the minimum amount of dissolved ozone should not be less than 2,5 mg/dm3.
