How do Bridge Biotechnology Generators make ESOL?


Water and Saline Input

Power to Electrode

Power to Electrode


Cathode Output



The liquid entering the core is a mixture of water and small amounts of saline.

The percentage of saline added to the reaction is controlled by the Bridge Biotechnology Generator. The speed of this pump and therefore the amount of saline mixed into the water is determined by the desired characteristics of the ESOL after the reaction. This is controlled by Bridge Biotechnologies specially written software.

Voltage is applied to the electrodes

An anode and a cathode are created. As the water and saline pass through the system the ions within the water molecules head towards the oppositely charged electrode.

Final position of the ions in the ESOL cell Ion movement across the ESOL cell

Ions have free movement through the partially permeable membrane forming unique liquids in each chamber of the core.

Our target is to maximise the Oxidation Reduction Potential (ORP) of our ESOL solutions whilst keeping free chlorine as low as possible. To achieve this Bridge Biotechnology must efficiently convert salt into ESOL. Inefficient conversion will result in large amounts of unnecessary chlorine in the final ESOL product and poor pathogen kill rates.

The Bridge Biotechnology Core is a proprietary design that has taken fifteen years to refine and gives the operator complete control of all the variables in the reaction.

What makes Bridge Biotechnologies ESOL Generators unique?

When the ions reach the opposite electrode new products are formed with the ions at the electrodes.

Bridge Biotechnology Generators are easy to operate. However inside the generators a carefully controlled reaction is taking place. A key component of a Generator is the core, represented on the right. This is the heart of the operation where water and a little bit of salt is turned into ESOL.

ESOL is formed containing a range of ions and molecules including hypochlorous acid, hydroxide ions, oxygen molecules and oxygen radicals, along with other shorter lived species.
