Electrodialysis in non-stationary mode


Using alternating asymmetric current, is a unique technology that has no analogues, and isused for the final purification of water with its deionization. This process, based on the transfer of the formed ions through the membrane under the action of a potential difference, leads to the separation of the substances dissolved in it from the water and its deionization.

Electrodialyzers is a filter-type installation consisting of cathode and anodic base plates, and repeating elements. Repetitive elements include alternating desalination and concentration chambers formed by cation-exchange and anion-exchange membranes, and a series of separation walls. Depending on the size of the anodes and cathodes, as well as the number of repeating elements of the electrodialyzer have different performance.


Application area - finishing water purification when desalting.

Electronionit processing in non-stationary modes


The technology of continuous deionization (modified electrodialysis), in which electrodialysis and ion exchange are combined, allows to achieve deep water purification - deeply desalinated water (chemically pure).


Application area:

- in the pharmaceutical industry (for the preparation of drugs);

- in the chemical industry (preparation of chemical reagents and solutions);

- in the electronics industry (manufactured chips are flushed with demineralized water);

- in the food industry, etc.

Filtration modules


Microfiltration in filtration modules (FM) is a baromembrane process occurring at a pressure of not more than 0.2÷0.3 MPa. In tangential filtration mode, water is separated from particles of emulsions and suspensions (organic macromolecules - humic acids), colloidal and suspended substances, which results in a significant clarification of water. Filtration modules are a block of parallel and serially connected, fixedly fixed tubular membranes of the cartridge type. In filter tubes made of specially selected synthetic polymeric materials and designed to work under pressure, water flows in high-speed flow, providing self-washing of surfaces, into tubular membranes, where under the action of pressure difference it seeps through the walls of the tubes. Separated from suspension, it gets inside the case and then goes outside. Its other part, concentrating, moves to the next membrane cartridge and undergoes a similar separation.
