Combined Ozonation-Flotation for the Treatment of Potable Water. Water Authorities are tightly regulated to guarantee removal of pollutants such as algal cells and toxins, cryptosporidium oocysts, and geosmin from drinking water. Processing options such as membrane filtration are effective but become very expensive when continuously operated to protect against occasional contamination events. This project aims to develop a fully-integrated process combining flotation and ozonation which can be ....Combined Ozonation-Flotation for the Treatment of Potable Water. Water Authorities are tightly regulated to guarantee removal of pollutants such as algal cells and toxins, cryptosporidium oocysts, and geosmin from drinking water. Processing options such as membrane filtration are effective but become very expensive when continuously operated to protect against occasional contamination events. This project aims to develop a fully-integrated process combining flotation and ozonation which can be operated continuously when required in a number of different modes to provide a barrier against a range of contamination events. The process utilises much of the existing water treatment infrastructure reducing capital and operating costs.Read moreRead less
Ozone-Enhanced Particle Removal in Water Treatment. Combined ozonation/biologically active carbon filtration provides effective contaminant removal while minimizing disinfection by-product formation. However, the cost of installation in conventional water treatment plants is very high. This project will investigate the beneficial influence of ozonation on the micro-flocculation of small particles, with the aim to optimising particle removal by sedimentation prior to filtration. To do this, requi ....Ozone-Enhanced Particle Removal in Water Treatment. Combined ozonation/biologically active carbon filtration provides effective contaminant removal while minimizing disinfection by-product formation. However, the cost of installation in conventional water treatment plants is very high. This project will investigate the beneficial influence of ozonation on the micro-flocculation of small particles, with the aim to optimising particle removal by sedimentation prior to filtration. To do this, requires a clear understanding of how dissolved ozone interacts with particle surfaces for different water chemistries. The ideal outcome would be to develop a robust water treatment system that required BAC filtration only and eliminated the need for a conventional sand filtration stage as well.Read moreRead less
