About

Small Type Bipolar Membrane Electrodialyzer and Electrodialyser 4020

Under the action of a DC electric field, the bipolar membrane can dissociate water and obtain hydrogen ions and hydroxide ions on both sides of the membrane. A bipolar membrane electrodialysis system that combines bipolar membranes with other anion and cation exchange membranes can convert salts in aqueous solutions into corresponding acids and bases without introducing new components, this method is called bipolar Membrane Electrodialysis. Bipolar membrane electrodialysis is not only used for the preparation of acids and bases, but if it is cleverly combined with unipolar membranes, it can achieve a variety of functions and be used in many fields.
The 4020 universal manual electrodialysis experimental device is a universal experimental equipment that integrates the two processes of electrodialysis (ED) and bipolar membrane electrodialysis (BPED). The device can realize the functions of manual operation and control of the device. The device can be used in electric power, chemical, petrochemical, chemical fiber, food, fermentation, biology, medicine, metallurgy, nuclear energy, aerospace and other industrial fields, and can meet the research needs of small and medium-scale experiments before engineering scale-up.

Principle of bipolar membrane electrodialysis two chambers:
1,Principles of preparing acid and alkali from strong base and weak acid salt-ACM

This principle is mainly used for the preparation of organic acids such as gluconic acid, malic acid, vC, propanesulfonic acid, oxalic acid, citric acid, tartaric acid, EDTA, lactic acid, methionine, morpholine ethanesulfonic acid, etc. The bipolar membrane process has no waste water discharge and by-product hydroxide Sodium can be recycled for the fermentation process.
2,The principle of acid and alkali preparation from strong acid and weak base salt-ABM

This principle is mainly used in the preparation of organic bases such as triethylamine hydrochloride, triethylamine tetramethylammonium salt, ornithine tetrapropyl bromide, quaternary amine base, tetraethylammonium hydroxide, methyldiethanolamine, etc. When hydroxide is introduced, cations are not added, and anions are separated.

Under standard operating conditions, the conversion efficiency of the membrane stack is as follows(Other salts can be calculated according to the corresponding equivalent molar mass):

Name	Reaction Formula	Processing Capacity(kg/h)	Power Consumption (kWh/kg)
NaCl	H2O+NaCl--HCl+NaOH	30	1.5
Na2SO4	Na2SO4+H2O--H2SO4+NaOH	36.4	1.2
LiCl	LiCl+H2O--LiOH+HCl	21.8	2.1
Li2SO4	Li2SO4+H2O--H2SO4+LiOH	28.2	1.6
NaNO3	NaNO3+H2O--HNO3+NaOH	43.6	1.1

Usually the acid-base equivalent concentration is 1N, and the acid-base concentration can be further increased by changing the operating conditions.

Applications Areas:

1, Preparation of acid and bases from inorganic salts (such as sodium sulfate, sodium chloride, lithium chloride, etc.)
