Depending on complexity and volume, waste water treatment can be extremely costly and difficult. DP has acquired ground breaking, patented GyrecatTM technology, which is a unique hybrid of an Advanced Oxidation Process (AOP) and which has significant advantages over existing AOP processes. The patented photocatalysis process has been tested on a range of organic contaminants and compounds commonly found in waste water.
The GyrecatTMprocess uses a non-slurry based titanium dioxide reactant which is less susceptible to contamination; produces less sludge, and is more energy efficient and cost-effective than the standard AOP processes. These advantages, and a smaller environmental footprint, make it suitable for both community and large scale water treatment applications, whilst a smaller scale module 'Gyrecat NexusTM' is particularly suitable for the treatment of brackish borehole water in agri-rural locations.
