The swimming pool filtration market (worth 3.2bn) currently lacks chemical-free alternatives despitecustomers’ demands of healthier, easier and cheaper solutions to pool water treatment. This project helps tofully realise the mass market potential for natural bio-filter based water treatment technology, throughinnovative and robust scientific research and development into aquatic pathogen behaviour and control usingbio-films. Project Objectives: Determine how our biofilms reduce levels of waterborne pathogens; ascertainwhether bio-films housed within a bio-filter allow re-introduction of pathogens in water; develop optimalhabitats & management of biofilms to maximise pathogen removal; & quantify pathogen survival rates on full-scale filtration models. The invaluable knowledge gained during the project will enable a set of optimisedoperational parameters (eg: optimal PH/ flow rates) and substrate properties (eg pore size, depth), whichmaximise the efficiency, repeatability and reliability of biofilm performance (w.r.t. pathogen control) for real-world conditions.
