About Anolyte and Catholyte


The Anolyte solution and Catholyte solution are the two distinct by products of the Electro Chemical Activation ( ECA Technology ) process. Basically the Anolyte solution is a disinfectant and the Catholyte is a detergent. These two solutions are used extensively by the Radical Waters clients in several different applications ranging from disinfection to cleaning in both an economical and an environmentally friendly manner.

If you would like to know more about Anolyte and Catholyte or the the ECA Technology process then read on.

The Anolyte solution is:


  • A pH neutral solution (pH between 6.8 and 7.3)
  • A high ORP solution (ORP above +900mV when fresh)
  • A highly effective broad spectrum disinfectant

Anolyte at a neutral pH, is a mixed oxidant solution which includes hypochlorous acid (HOCl) and has a high Oxidation Reduction Potential (ORP) of approximately > + 900mV. The Anolyte solution can be manipulated according to specific application requirements and combinations of the solutions may be generated where a combined detergent and disinfectant effect is required.

Oxidation Reduction Potential (ORP)
represents the tendency of a chemical compound to scavenge or acquire electrons, thereby becoming reduced. Each chemical entity has its own intrinsic oxidation-reduction potential (ORP) and the more positive the potential, the greater the compound's affinity for energy (electrons) and hence its tendency to become reduced. Thus the highly oxidised Anolyte solutions will actively scavenge electrons from any viable source and local microbes represent the most readily available source of energy. Upon loss of electrons, the microbes also lose their ability to maintain their structure and function and they rapidly absorb water, swell and burst.


The Catholyte solution is:

  • An alkaline pH solution (pH between 10.7 and 11.1)
  • A low ORP solution (ORP less than -400mV when fresh, up to +200mV when stored for a few days)
  • A highly effective detergent and cleaning agent

Catholyte, has a very low ORP of approximately < -650mV, and is produced at a pH of approximately 10.8. The Catholyte is a very effective detergent and is very efficient in removing a variety of soils ranging from syrups to fats and oils.

The combination of the reducing ORP in conjunction with the chemical constituents of Catholyte, produce an effective soil mobilising and detergent effect which has been shown to be effective in removing organic residues as well as biological biofilms
