Embodiment 1
[0052] Embodiment 1 adopts electrodialyzer of the present invention to reclaim glutamate from fermented liquid
[0053] The electrodialyzer of the present invention is used to recover glutamate from glutamic acid simulated fermentation broth. It operates intermittently at constant voltage 20V, constant temperature 30°C, and cycle. The initial feed of each chamber is as follows: desalination chamber: 1000ml glutamate simulated fermentation broth (100g L -1 Sodium glutamate or ammonium glutamate), the circulation flow is 100L h -1 ;Concentration chamber: 1000ml initial concentration is 1g L -1 Glutamate (sodium glutamate or ammonium glutamate) solution, the circulation flow rate is 100L h -1 ; Pole chamber: 1000ml 0.2mol L -1 Sodium sulfate solution, the circulation flow is 40L h -1 .
[0054] Glutamic acid simulated fermentation broth: With the prolongation of the running time, the concentration of the desalted solution gradually decreased, and the concentration of the co...
Embodiment 2
[0056] Embodiment 2 adopts electrodialyzer of the present invention to desalt from glutamic acid fermentation liquid
[0057] The electrodialyzer of the invention is used to remove sulfate from the simulated glutamic acid isoelectric mother liquor. It operates intermittently at a constant temperature of 30°C, constant pressure, and circulation. The initial feed is as follows: Desalination chamber: 1000ml sulfate simulated aqueous solution, circulation flow rate is 100L h -1 ;Concentration chamber: 1000ml initial concentration is 0.05mol L -1 Ammonium sulfate solution, the circulation flow rate is 100L h -1 ; Pole chamber: 1000ml 0.2mol L -1 Sodium sulfate solution, the circulation flow is 40L h -1 .
[0058] Simulated fermentation broth: investigate sulfate concentration, desalination rate, current efficiency and energy consumption during electrodialysis desalination of simulated solution. When the feed volume of the desalting chamber: the feed volume of the concentratin...
