Electrodialysis of whey: practice of application at the Bryuhovetskii Canned Milks Plant

Taking into account situation at cheese making plants and at the Bryuhovetskii Canned Milks Plant technology was worked out for receiving demineralized whey powder with demineralization levels of 50, 70 and 90%. Efficiency of the method was assessed at pilot plant Mega Y (Czechia) and in December 2006 an industrial plant Mega with the capacity of 200 t of raw whey processing per 24 hours was put into operation. The demineralization level is 70%.
Technological scheme of electrodialysis with reversion for 70 and 90% levels includes two parallel modules connected with pump station of three centrifugal pumps provided with filters, two heat exchanging facilities for maintaining temperature in the demineralization and concentrating circuit, valves system and pipes for reversion.
