AQUACHLOR – general name of electrolyser range produced by LLC LET.

AQUACHLOR is an electrochemical system for chlore-alkali brine electrolysis.

Our technology allows to use the cheap types of raw salt, which greatly reduces the cost of the final product.



The range of basic equipment “AQUACHLOR” is represented by installations of various capacities.

Capacity of “AQUACHLOR-500” is 12 kg of active chlorine per day.

Capacity of “AQUACHLOR-100” is 2.4 kg of active chlorine per day.

Capacity of “AQUACHLOR-50” is 1.2 kg of active chlorine per day.

Capacity of “AQUACHLOR-30” is 0.72 kg of active chlorine per day.

Equipment “AQUACHLOR” can be installed in a complex, which allows producing any concentration of active chlorine.

In the GALLERY section of our website you can learn more about our equipment.

Installation complexes “AQUACHLOR” are presented in the INSTALLATIONS section.

We invite you to contact with the specialists of LLC “LET” to make a suitable choice for you.

You can contact us by any comfortable way and we will be happy to give you any consultation about our equipment at anytime.

If you have doubts about your choice, we can offer you to fill THE QUESTIONNAIRE.


The principle of a diaphragm electrolysis is realized in the equipment “AQUACHLOR”.

Sodium chloride solution goes to the device reactors, where during the electrochemical reaction process chlorine (with small amount of chlorine dioxide and ozone), hydrogen, sodium dioxide (alkali) are formed.

Electrodes of the reactor are separated by ceramic porous diaphragm, which allows reaction products to be separated.

Chlorine-containing substances mix with water and form oxidant solution with pH=3, which is used for water disinfection.

Hydrogen is diluted with air and removed from the room.

Alkaline catholyte is removed by separated flow from the device.

The catholyte is used as a reagent for the stabilization treatment of water.

If necessary, you can get a neutral oxidant solution, which is similar to sodium hypochlorite with pH=6-7, by using any model of “AQUACHLOR” equipment.

This does not require changes in the design of the equipment.

Thus, it is possible to get 2 types of reagents for disinfection by using equipment “Aquachlor”, depending on the needs the customer:

  1. Sour oxidants solution (5 gr/L of active chlorine). Due to pH level of the reagent and in addition to chlorine ozone and chlorine dioxide, acidic oxidant solution is the most effective for water disinfection. It is characterized by minimal formation of organochlorine
  2. Neutral oxidant solution (5 gr/L of active chlorine). It is the same as sodium hypochlorite. During the working process alkaline solution isn’t formed.


Equipment “Aquachlor” is intended for production use reagent for the disinfection of water.


Production of own reagent allows to reduce the cost of disinfection,
avoid expenses for transportation and storage of dangerous reagents, withdraw the object from the GCO registry.
For more information about the economic efficiency indicators, please see the CALCULATOR section of our website.

Our equipment is used:

1.     On the places of preparation of household-drinking water.

  1. On water treatment facilities for technical purposes.
  2. At sewage treatment plants.
  3. In swimming pools.

Oxidant solution can be used as the only reagent for disinfection, as well as in combination with ultraviolet devices to maintain the sanitary condition of buildings and ensure the safety of water during transportation to the consumer.
