Aquachlor-GPHE is an electrolysis plant for obtaining low-concentrated sodium hypochlorite 0.8% from a solution of table salt at the site of application.

LET LLC supplies, installs and maintains sodium hypochlorite generators of any capacity. By the link (or in the “Reviews” section) you can get acquainted with the overview of the high-performance complex.

We also perform coating of ORTA AND OIRT electrodes.

Our company offers the most favorable conditions, as it performs the coating of the electrodes on its own, on its own equipment in accordance with the permits (“Certificate of special registration” No. 0160028664 in the State inspection of assay supervision of the Russian State Assay Chamber).

Model range of electrolysis plants

Typical installations of “Aquachlor-GPH” have a capacity from 0.5 to 1000 kg of active chlorine / day.

Electrolysis plants are installed in complexes, which allows you to get any necessary performance for active chlorine.

Technology and reagent

“Aquachlor-GPHE” – flow electrolyzers. In the sodium hypochlorite generator, the principle of non-fragmented electrolysis is implemented.

The design of the flow-through electrolyzer is arranged so that a solution of sodium chloride enters the reactors of the installation, where chlorine, hydrogen and sodium hydroxide (alkali) are formed during the electrochemical reaction.

The reactor electrodes are not divided into cathode and anode zones, which makes it possible to obtain low-concentrated sodium hypochlorite directly in the reactors of the installation.

The hydrogen is diluted with air and removed from the room.

Advantages of electrolysis plants

Aquahlor-GPHE flow electrolyzers are reliable and easy-to-maintain equipment.

The requirements for the quality of the saline solution are minimal (see the section Salt solution preparation complexes). In combination with equipment for cleaning salt solution, it is allowed to use salt of any quality as a raw material. Flow-through electrolysis plants are widespread and have proven themselves well at water treatment and sanitation facilities.
