Method for obtaining a biopolymer from waste acid whey and/or sweet rennet whey and the installation for obtaining a biopolymer from waste acid whey and/or sweet rennet whey

摘要

method for biopolimeru whey waste acidic and / or fresh rennet is that neutralized in a fermentation process to ph 7 sodium lactate solution is subjected to ion chamber in water elektrodializie tetramembranowej divided objectives, in which lactate anion these in combination with cations form hydrogen diluted pure lactic acid.and sodium cations in combination with anionami wodorotlenkowymi form sodium hydroxide.stored in cell compartment electrodialysis dilute pure lactic acid is subjected to concentration process in hydrofobowym, membrane module destylacyjnym with submerged in his chambers peltiera stressed cells, which cyrkuluju0105ca in the water and lactic acid in solution heat up and cooling with simultaneous,according to the heating and cooling phase hydrophobic membrane diffusion of water vapour and skropleniem distillate. concentrated lactic acid is heading for a section where a known polymerization, catalytic polymerization process is to biopolimeru phase.installation for biopolimeru whey waste acidic and / or fresh rennet built section filtration, fermentation, membrane module demineralisation while compaction and solution polymerization section, purification and vacuum section, has a sekcj and fermentation (3) tetramembranowu0105 electrodialysis ion chamber (4),consisting of two extreme carbon electrodes, the cation and anion (10) (11) and the five target (12a, 12b, 12c, 12d, 12e) separated polar membranami jonowymiennymi (13a, 13b, 13c, 13d).side objectives (12a, 12b, 12d, 12e) are filled with water and electrodialysis chamber (4) is a membrane distillation module (5), consisting of four chambers (15a, 15b, 15c, 15d), separated by metal plates (16) alternately with the link peltiera (17) and hydrofobowu0105 paroprzepu szczalnu0105 membrane (18), whereby the metal plates (16) between the chamber (15a, 15b) and a chamber (15c15d) is the peltiera (l7), and between the chamber (15b, 15c) is embedded hydrofobowa paroprzepuszczalna membrane (18). the surfaces of carbon electrodes (10, 11) and polar membranes (13a, 13b, 13c, 13d) electrodialysis chamber (4) are equal, and the metal plates (16) chambers (15a, 15b, 15c, 15d) in destylacyjnym module (5) are covered with a layer of kwasoodpornu0105, preferably ptfe.
