Drinking Water Disinfection

“This is science for the real world addressing urgent problems through positive partnership working. The work being conducted by Darren's team and our partners, Portsmouth Aviation, Pentair and Bridge Biotechnology is world class."

Disinfecting Water with ESOL

There are significant drawbacks to traditional chlorine disinfection:

- strict requirements for transportation and storage

- potential risk to health in case of leakage

- formation of disinfection by-products, such as trihalomethanes.

- formation of bromates and brom-organic disinfection by-products at   presence of bromides

Water Disinfection using chlorine

ESOL has a number of applications in both the drinking water and waste water sectors of the water industry.

 

ESOL is currently used as a direct chlorine replacement in mobile water disinfection units. The oxidation reduction potential 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.

 

ESOL also has applications in the maintenance of existing infrastructure and is particularly effective against biofilm build up.

ESOL Development - From pond to cup - Tackling the global need for clean drinking water

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 ultrafiltration membrane completely free from biofouling

- To disinfect the final water product and provide a residual kill protecting the water from recolonization of pathogens after disinfection

 

The system was trialled 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.

Proof of Concept at UWE

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