ESOL drinking water approval

Our ESOL electrolysed water technology has been given drinking water approval

ESOL has been approved under regulation 31 of the Water Supply Regulations 2000 for use in public water supplies in the UK.

What does this mean?

Chlorine (hypochlorite) is added to our tap water to kill bacteria and microbes in tap water. Although deemed safe, chlorine itself has many harmful properties

Disinfecting Water with Chlorine

There are some significant drawbacks to traditional chlorine disinfection:

  • Strict requirements for transportation and storage
  • Potential risk to the health in case of leakage
  • Formation of disinfection by-products, such as trihalomethanes (used in solvent and refrigeration industries and are a environmental pollution)
  • Formation of bromates and brom-organic disinfection by-products at presence of bromides (Bromate in drinking water is undesirable because it is a suspected human carcinogen)

What are the alternatives?

ESOL has drinking water approval and with this brings several advantages:

  • There are a number of applications for ESOL in both the drinking water and waste water sectors of the water industry.
  • As the product is made ‘on site’ there is no need for transportation, reordering or the fear of stock shortage
  • Along with our technology, ESOL (electrolysed water) is made with water, electricity and salt
  • It is safe to drink
  • ESOL reverts back to water after a period of time
  • Environmentally friendly

Mobile drinking water disinfection units

Our technology is currently used as a direct chlorine replacement in Mobile drinking water disinfection units

Since 2013, Bridge Biotechnology have worked in collaboration with Portsmouth Aviation and the University of the West of England to develop a compact and portable water purification system capable of delivering clean drinking water at source.

 ESOL is a key component of this system and serves two purposes:

  • To keep the ultra-filtration membrane completely free from bio-fouling
  • To disinfect the final water product and provide a residual kill protecting the water from recolonization of pathogens after disinfection

 The system was trialed in lab based setting first at the University of the West of England and was independently tested and validated by the

UK’s Health Protection Agency, the University of the West of England (UWE) and Wessex Water Laboratories, meeting Drinking Water Institute (DWI) and World Health Organisation (WHO) standards.

 The system has now been commercially scaled up and is fitted into standard 20ft and 40ft containers making each unit easy to transport by road, ship or train.

Our ESOL technology is installed with an indicator panel – using this panel oxidation reduction potential (ORP) can be used to accurately indicate if water is pathogen free or still dangerous to drink.

This method is scientifically validated and the ESOL product has a number of benefits over chlorine including; safety, cost and environmental sustainability.

In the UK clean, safe drinking water ‘comes as standard’ but do you really know what is in your tap water?
