EMERALD devices are based on electrochemical activation technology (ECA). The essence of ECA technology consists in electrochemical synthesis and subsequent use of electrochemically activated (metastable) substances instead of traditional stable reagents.

The main working element of EMERALD devices is the electrochemical Bakhir Module (MB element) with a porous ceramic diaphragm. MB electrochemical modules are protected by patents № RU 2350692; USA 8,961,750; UK 2479286.

EMERALD devices are developed and manufactured in R&D partnership with the Vitold Bakhir Electrochemical Systems and Technologies Institute — the world’s leading scientific center in the field of electrochemical activation. More than 50 years of experience and modern discoveries have made it possible to manufacture EMERALD devices unrivaled throughout the world in terms of their technical features.

EMERALD HOME device for household water purification and ionization:

  • 60 liters per hour
  • 2 MB-11 elements
MERALD AQUACHLOR device for large-scale water disinfection:

  • 2,000 m3 per hour (2.0 kg/h FAC capacity*)
  • 16 MB-26 elements

*Capacity in terms of free available chlorine

Compact and safe chlorine-caustic plant based on 20 units of EMERALD ECOCHLOR devices:

  • 120.0 kg/h FAC capacity
  • 960 MB-26 elements

Electrochemical mb elements advantages:

  • The ceramic diaphragms do not require periodic replacement and can be easily washed with any common acids (citric, acetic, hydrochloric or phosphoric) in case of impurities.
  • MB elements service life is more than 50,000 hours of continuous work.
  • Wide possible concentration of source electrolytes: from 0.001 to 10 mol per liter.
  • Automatic anode cooling and self-cleaning of the diaphragm and cathode chamber
High significance of ECA technologies is noted in the resolution of the BRICS Water Forum Expert Council in 2016:

“To strengthen cooperation of the BRICS countries in the areas of activities related to industrial production of the most important products of the chemical industry (chlorine, caustic soda, persulfuric acid, hydrogen peroxide) at the places of consumption, as well as for reagent[1]free regulation of physical and chemical properties of water and aqueous solutions, through the use of electrochemical activation in technological processes…”
